Using the Skupper console
The Skupper console provides data and visualizations of the traffic flow between Skupper sites.
| This is a preview feature and may change before becoming fully supported by skupper.io. |
Enabling the Skupper console
By default, when you create a Skupper site, a Skupper console is not available.
When enabled, the Skupper console URL is displayed whenever you check site status using skupper status
.
-
A Kubernetes namespace where you plan to create a site
-
Determine which site in your service network is best to enable the console.
Enabling the console also requires that you enable the flow-collector component, which requires resources to process traffic data from all sites. You might locate the console using the following criteria:
-
Does the service network cross a firewall? For example, if you want the console to be available only inside the firewall, you need to locate the flow-collector and console on a site inside the firewall.
-
Is there a site that processes more traffic than other sites? For example, if you have a frontend component that calls a set of services from other sites, it might make sense to locate the flow collector and console on that site to minimize data traffic.
-
Is there a site with more or cheaper resources that you want to use? For example, if you have two sites, A and B, and resources are more expensive on site A, you might want to locate the flow collector and console on site B.
-
-
Create a site with the flow collector and console enabled:
$ skupper init --enable-console --enable-flow-collector
Currently, you must enable the console on the same site as you enable the flow collector. This requirement may change before the console is fully supported by skupper.io.
Accessing the Skupper console
By default, the Skupper console is protected by credentials available in the skupper-console-users
secret.
-
Determine the Skupper console URL using the
skupper
CLI, for example:$ skupper status Skupper is enabled for namespace "west" in interior mode. It is not connected to any other sites. It has no exposed services. The site console url is: https://skupper-west.apps-crc.testing
-
Browse to the Skupper console URL. The credential prompt depends on how the site was created using
skupper init
:-
Using the
--console-auth unsecured
option, you are not prompted for credentials. -
Using the
--console-auth openshift
option, you are prompted to enter OpenShift cluster credentials. -
Using the default or
--console-user <user> --console-password <password>
options, you are prompted to enter those credentials.
-
-
If you created the site using default settings, that is
skupper init
, a random password is generated for theadmin
user. To retrieve the password theadmin
user:$ kubectl get secret skupper-console-users -o jsonpath={.data.admin} | base64 -d JNZWzMHtyg
Exploring the Skupper console
After exposing a service on the service network, you create an address, that is, a service name and port number associated with a site. There might be many replicas associated with an address. These replicas are shown in the Skupper console as processes. Not all participants on a service network are services. For example, a frontend deployment might call an exposed service named backend, but that frontend is not part of the service network. In the console, both are shown so that you can view the traffic and these are called components.
The Skupper console provides an overview of the following:
-
Topology
-
Addresses
-
Sites
-
Components
-
Processes
The Skupper console also provides useful networking information about the service network, for example, traffic levels.
-
Check the Sites tab. All your sites should be listed. See the Topology tab to view how the sites are linked.
-
Check that all the services you exposed are visible in the Components tab.
-
Click a component to show the component details and associated processes.
-
Click on a process to display the process traffic.
The process detail displays the associated image, host, and addresses. You can also view the clients that are calling the process. -
Click Addresses and choose an address to show the details for that address. This shows the set of servers that are exposed across the service network.
| To view information about each window, click the ? icon. |

It seems once you have gotten past automating building, testing and deploying you are in a different territory beyond simple scripting. Sure you could write a script (Ant) which aggregates your errors and produces a report, but at that point you are allowing your scripting to bleed into the domain of what the application would be better equipped to handle.\r\n\r\nIt is best to ensure that build scripts do not go too far. To script a database you will likely have PL/SQL (or T/SQL) procedures you can schedule or set up with a trigger to run on an as needed basis which works best in that domain. I know how trivial it is to create a DTS package in SQL Server and schedule it to run nightly. And by allowing that code to be written in that language native to that area you allow the experts in that area to maintain it because not everyone on a team will take the time to learn to write an Ant script.\r\n\r\nI also consider that automation scripts should be a very small portion of a project which act as the glue to keep everything together. If they become a significant portion of your project you have to reconsider the role of that scripts. It reminds me of how you can put looping and conditional statments into XSLT and soon you end programming more in your templating solution than you do in your actual code. Just because you can do it, does not mean it is a good idea." - id: 204 author: Geoff Lane author_email<EMAIL_ADDRESS>author_url: http://www.zorched.net date: '2006-08-20 21:10:38 -0400' date_gmt: '2006-08-21 03:10:38 -0400' content: "I want to talk about relentless build automation, once you get outside of the things that you need to get a system up and running from source, then you're outside that realm. So, error reporting wouldn't count in my book...\r\n\r\nThe beauty of a shared automation script is that not everyone on the team has to be an expert in that scripting technology. Everyone on the team can benefit from the automation expertise of only a few people. The same way that you can benefit from having a CSS expert or a SQL expert. Everyone will know the basics, but you'll have a \"goto guy\" for more complex tasks.\r\n\r\nI also don't think that script size is relevant, they should be as big as they need to be and no bigger. Automation with something like Ant is programming in a Domain Specific Language. It is a DSL that is optimized for scripting repeatable developer tasks (just like XSLT is a DSL for transforming XML documents). DSLs can be much more powerful and expressive because they are working at a higher level of abstraction.

How far is going to far when you are doing build automation? My answer to that question, is that it's basically not possible to go to far. Any task that you need to do more than three times deserves automation. Three times is my heuristic. The longer and more complex the task, the smaller the number you should allow yourself to do it by hand. Compiling for example is a pain if you don't automate it, so you automate it the first time. Computers are good at one thing, running algorithms. If you are doing those algorithms by hand, you're wasting your computer's potential.
Reducing errors is easy. We want to have a repeatable, dependable process that anyone can use to achieve the same results. If your deploy master has to know 15 steps and the ins and outs of some complex process, what happens when she goes on vacation? You don't do deployment.
But being lazy? Yes! A truly great computer programmer is lazy and does everything in their power to avoid having to work that they've already done before. Likewise, if you've done it 10 times, doesn't it get boring to do the same thing over and over again? Wouldn't you rather be getting coffee or reading blogs while your computer works at what it does best? In addition to general laziness, automation will make your life easier when you want to do other things that you know you should be doing like unit testing, integration testing and functional testing.
Going back to my introduction, I say automate everything that you or someone new coming onto a project will need to do more than a few times. A little bit of effort up front can save every member of a team a lot of effort later on. So, as a punch list to get you started:
Most people doing Java development will automate code compilation and packaging all of the time. Some of the times, they'll automate unit tests, sometimes deployment, and rarely a few other things. We usually use some excellent script-based tools for that kind of thing like Ant or Maven. Even if you do all of these things, is that going far enough? I think that for most projects the answer is no.
If you are slightly more ambitious you will also automate:
There, now you've got all of your day-to-day activities automated. So you must be done right?
Databases are the bane of automation. People don't take the time to script their database creation or to script their default or testing data. When you don't script your database, you make integration and functional testing very difficult. It's really easy to write functional tests and integration tests if they rely on the data being in a known state. If they do not, then running them is very difficult because the data underneath is always changing. That usually means that integration and automated functional testing are deemed to hard and are not done. But don't blame the tests. You're avoiding a little bit of work, that if you did it, would allow you to avoid A LOT of work. (I think little jobs that prevent you from having to do big jobs are a good tradeoff.)
Generating your database will make new team members lives a breeze. They should be able to check out a project from source control and with one simple command, generate a database, compile the code, run the tests and know with confidence that everything is working for them. When they make any changes to the project they can repeat this process to know with confidence that they haven't broken anything. Likewise in day-to-day development, being able to get back to a known state is going to give you the ability to develop with more confidence and test with ease.
Ant has a core task for running SQL queries, so you don't even need any other tools to accomplish this. One problem that you might run into is that running DDL commands in JDBC can cause some problems. I found a great article on executing PL/SQL with Ant that you can probably apply to other databases as well. It allows you to run more database specific queries to build your schema from a blank database. This helped me overcome the last hurdle in a recent project to get it so I had the entire database scripted from scratch. So check it out.
I find that having a few standard Ant tasks makes this a breeze:
Together these tasks can be woven together to fully to create the full database. To support development and testing, it is also handy to have loadable datasets around. Either maintain a list of SQL INSERT statements or use a tool like DBUnit to load the data into your database. Often it can be nice to have a few sets of base data:
The only thing lacking is an easy way to dump a schema from a working database so that you can use nice GUI tools to modify the database and then dump it out using an easy Ant target. Even with this, you'll likely need to maintain change scripts so that you can apply them to working production systems without wiping out all of the data. I guess since I'm complaining, that will have to be my next side project. Leave a comment if you know how to do this.
What things do you like to automate that you see people skipping on projects?

The Porting SDK contains a modified version of the Flash Player designed to help a 3rd party easily port Flash to any platform or application, as well as the documentation to perform this task. The code in the Porting SDK is a partial rewrite of the Flash 4 code, modified for ease of porting and platform independence.
The code as provided compiles on a Win32 system.
A Visual C++ project file is provided. The code is ready to compile with one caveat: if you are not on a system that supports Unicode Cut and Paste, comment out:
#define EDITTEXT_CLIPBOARD_WIDE
in global.h. (In the very likely case you donít know, compile the project and if you get an error that CF_UNICODETEXT is undefined, then comment out EDITTEXT_CLIPBOARD_WIDE.)
After you compile, the Flash player should run from your C++ IDE.
Is provided in the Documentation subdirectory. We recommend starting with Design.htm (or design.doc in the Docs in MSWord directory.)
We welcome your feedback and comments on the product, and hope you will find it meets your needs. We
would like to extend thanks to the Beta testers who have contributed, and continue to contribute, their comments on the product.
Thanks again, and we look forward to talking to you.

NAME
munin_selinux - Security Enhanced Linux Policy for the munin processesDESCRIPTION
SELinux Linux secures munin (Munin network-wide load graphing (formerly LRRD)) processes via flexible mandatory access control.
FILE CONTEXTS
SELinux requires files to have an extended attribute to define the file type.You can see the context of a file using the -Z option to lsP Policy governs the access confined processes have to these files. SELinux munin policy is very flexible allowing users to setup their munin processes in as secure a method as possible.
The following file types are defined for munin:
munin_disk_plugin_exec_t
- Set files with the munin_disk_plugin_exec_t type, if you want to transition an executable to the munin_disk_plugin_t domain.

Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels.
PORT TYPES
SELinux defines port types to represent TCP and UDP ports.You can see the types associated with a port by using the following command:
semanage port -l
Policy governs the access confined processes have to these ports. SELinux munin policy is very flexible allowing users to setup their munin processes in as secure a method as possible.
The following port types are defined for munin:
- munin_port_t
-
Default Defined Ports: tcp 8021
PROCESS TYPES
SELinux defines process types (domains) for each process running on the systemYou can see the context of a process using the -Z option to psP Policy governs the access confined processes have to files. SELinux munin policy is very flexible allowing users to setup their munin processes in as secure a method as possible.
The following process types are defined for munin:
munin_mail_plugin_t, munin_disk_plugin_t, munin_services_plugin_t, munin_selinux_plugin_t, munin_system_plugin_t, munin_t
Note: semanage permissive -a PROCESS_TYPE can be used to make a process type permissive. Permissive process types are not denied access by SELinux. AVC messages will still be generated.
COMMANDS
semanage fcontext can also be used to manipulate default file context mappings.semanage permissive can also be used to manipulate whether or not a process type is permissive.
semanage module can also be used to enable/disable/install/remove policy modules.
semanage port can also be used to manipulate the port definitions
system-config-selinux is a GUI tool available to customize SELinux policy settings.

I just graduated and got my Software Engineer Certificate from Prime Digital Academy. Prime Digital Academy is an intensive 20-week program that prepares student so they can join the industry as entry-level software engineers. At Prime we learn the most update to date technologies like HTML5, CSS, JavaScript, AngularJS, React.JS, jQuery and Node.js to provide foundational concepts, techniques and design patterns essential in all coding environments. I look forward to utilizing all the skills that I have learned at Prime to build things that only people can imagine about.
During my time with Prime Digital Academy I was able to create a full stack application called Sa-Bai-Dee (Learn Lao). Learning Lao is hard especially if you don't know where to start. If you search online all the contents that you want to study is not all in one page. With Sa-Bai-Dee it list the basic of what you should be studying. You can favorite the words/vocabulary that you want to study more and add personal comments too.
At Prime, we also get the honor to create an application that help solve a solution for a real life client. For 4 weeks, I worked with a team of 5 members where we planned, scoped, and created an application called JFuerst Scheduling that help streamline our client scheduling system by integrating the client's third party api and google api to help calculate each photographer drive time, mileages, and display all the needed information in one place. Instead of using 3-4 application to create the photographer schedule, our client can just use one.
Prior to Prime I was in the financial industry for 4+ years and have learned a ton regarding the industry. During my time there, I was in the Production department, Customer Service department and before I left was in the Account Management team where I help mange investors accounts. Not only that, but I was able to acquired a lot of the soft skills that came with all the roles. I'm excited to continue using all the skills that I have learned thus far.

GPKG -- GeoPackage raster
Driver short name
GPKG
Build dependencies
libsqlite3 (and any or all of PNG, JPEG, WEBP drivers)
This driver implements full read/creation/update of tables containing raster tiles in the OGC GeoPackage format standard. The GeoPackage standard uses a SQLite database file as a generic container, and the standard defines:
Expected metadata tables (
gpkg_contents
,gpkg_spatial_ref_sys
,gpkg_tile_matrix
,gpkg_tile_matrix_set
, ...)Tile format encoding (PNG and JPEG for base specification, WebP as extension) and tiling conventions
Naming and conventions for extensions
This driver reads and writes SQLite files from the file system, so it must be run by a user with read/write access to the files it is working with.
The driver can also handle GeoPackage vectors. See GeoPackage vector documentation page
Various kind of input datasets can be converted to GeoPackage raster :
Single band grey level
Single band with R,G,B or R,G,B,A color table
Two bands: first band with grey level, second band with alpha channel
Three bands: Red, Green, Blue
Four band: Red, Green, Blue, Alpha
GeoPackage rasters only support Byte data type.
All raster extensions standardized by the GeoPackage specification are supported in read and creation :
gpkg_webp: when storing WebP tiles, provided that GDAL is compiled against libwebp.
gpkg_zoom_other: when resolution of consecutive zoom levels does not vary with a factor of 2.
Driver capabilities
Supports CreateCopy()
This driver supports the GDALDriver::CreateCopy()
operation
Supports Create()
This driver supports the GDALDriver::Create()
operation
Supports Georeferencing
This driver supports georeferencing
Supports VirtualIO
This driver supports virtual I/O operations (/vsimem/, etc.)
Opening options
By default, the driver will expose a GeoPackage dataset as a four band (Red,Green, Blue,Alpha) dataset, which gives the maximum compatibility with the various encodings of tiles that can be stored. It is possible to specify an explicit number of bands with the BAND_COUNT opening option. Starting with GDAL 3.6, a special metadata item is written when creating a GeoPackage raster with GDAL (when using the default CUSTOM tiling scheme), and it is used on reading as the default number of bands.
The driver will use the geographic/projected extent indicated in the gpkg_contents table, and do necessary clipping, if needed, to respect that extent. However that information being optional, if omitted, the driver will use the extent provided by the gpkg_tile_matrix_set, which covers the extent at all zoom levels. The user can also specify the USE_TILE_EXTENT=YES open option to use the actual extent of tiles at the maximum zoom level. Or it can specify any of MINX/MINY/MAXX/MAXY to have a custom extent.
The following open options are available:
TABLE=<table_name>: Name of the table containing the tiles (called "Tile Pyramid User Data Table" in the GeoPackage specification language). If the GeoPackage dataset only contains one table, this option is not necessary. Otherwise, it is required.
ZOOM_LEVEL=value: Integer value between 0 and the maximum filled in the gpkg_tile_matrix table. By default, the driver will select the maximum zoom level, such as at least one tile at that zoom level is found in the raster table.
BAND_COUNT=[AUTO/1/2/3/4]: Number of bands of the dataset exposed after opening. Only used for Byte data type. Some conversions will be done when possible and implemented, but this might fail in some cases, depending on the BAND_COUNT value and the number of bands of the tile. Before GDAL 3.6, the default value is 4 (which is the always safe value). Starting with GDAL 3.6, when the metadata of the file contains an hint of the number of bands, this one is used in AUTO mode (default value), or fallback to 4 when it is not present.
MINX=value: Minimum longitude/easting of the area of interest.
MINY=value: Minimum latitude/northing of the area of interest.
MAXX=value: Maximum longitude/easting of the area of interest.
MAXY=value: Maximum latitude/northing of the area of interest.
USE_TILE_EXTENT=[YES/NO]: Defaults to
NO
. Whether to use the extent of actual existing tiles at the zoom level of the full resolution dataset.TILE_FORMAT=[PNG_JPEG/PNG/PNG8/JPEG/WEBP]: Format used to store tiles. See Tile formats. Only used in update mode and for Byte data type. Defaults to PNG_JPEG, unless, starting with GDAL 3.6, if the raster has one band, in which case PNG is used.
QUALITY=1-100: Defaults to
75
. Quality setting for JPEG and WEBP compression. Only used in update mode.ZLEVEL=1-9: Defaults to
6
. DEFLATE compression level for PNG tiles. Only used in update mode.DITHER=[YES/NO]: Defaults to
NO
. Whether to use Floyd-Steinberg dithering (forTILE_FORMAT=PNG8
). Only used in update mode.
Note: open options are typically specified with "-oo name=value" syntax in most GDAL utilities, or with the GDALOpenEx() API call.
Creation issues
Depending of the number of bands of the input dataset and the tile format selected, the driver will do the necessary conversions to be compatible with the tile format.
To add several tile tables to a GeoPackage dataset (seen as GDAL subdatasets), or to add a tile table to an existing vector-only GeoPackage, the generic APPEND_SUBDATASET=YES creation option must be provided.
Fully transparent tiles will not be written to the database, as allowed by the format.
The driver implements the Create() and IWriteBlock() methods, so that arbitrary writing of raster blocks is possible, enabling the direct use of GeoPackage as the output dataset of utilities such as gdalwarp.
On creation, raster blocks can be written only if the geotransformation matrix has been set with SetGeoTransform() This is effectively needed to determine the zoom level of the full resolution dataset based on the pixel resolution, dataset and tile dimensions.
Technical/implementation note: when a dataset is opened with a non-default area of interest (i.e. use of MINX,MINY,MAXX,MAXY or USE_TILE_EXTENT open option), or when creating/ opening a dataset with a non-custom tiling scheme, it is possible that GDAL blocks do not exactly match a single GeoPackage tile. In which case, each GDAL block will overlap four GeoPackage tiles. This is easily handled on the read side, but on creation/update side, such configuration could cause numerous decompression/ recompression of tiles to be done, which might cause unnecessary quality loss when using lossy compression (JPEG, WebP). To avoid that, the driver will create a temporary database next to the main GeoPackage file to store partial GeoPackage tiles in a lossless (and uncompressed) way. Once a tile has received data for its four quadrants and for all the bands (or the dataset is closed or explicitly flushed with FlushCache()), those uncompressed tiles are definitely transferred to the GeoPackage file with the appropriate compression. All of this is transparent to the user of GDAL API/utilities
The driver updates the GeoPackage last_change
timestamp when the file is
created or modified. If consistent binary output is required for
reproducibility, the timestamp can be forced to a specific value by setting the
OGR_CURRENT_DATE
global configuration option.
When setting the option, take care to meet the specific time format
requirement of the GeoPackage standard,
e.g. for version 1.2.
Tile formats
Tiled rasters
This section only applies for raster of Byte data type.
GeoPackage can store tiles in different formats, PNG and/or JPEG for the baseline specification, and WebP for extended GeoPackage. Support for those tile formats depend if the underlying drivers are available in GDAL, which is generally the case for PNG and JPEG, but not necessarily for WebP since it requires GDAL to be compiled against the optional libwebp.
By default, GDAL will use a mix of PNG and JPEG tiles (PNG_JPEG tile format, or AUTO). PNG tiles will be used to store tiles that are not completely opaque, either because input dataset has an alpha channel with non fully opaque content, or because tiles are partial due to clipping at the right or bottom edges of the raster, or when a dataset is opened with a non-default area of interest, or with a non-custom tiling scheme. On the contrary, for fully opaque tiles, JPEG format will be used. Starting with GDAL 3.6, if the raster has only one band, the default is PNG.
It is possible to select one unique tile format by setting the creation/open option TILE_FORMAT to one of PNG, JPEG or WEBP. When using JPEG, the alpha channel will not be stored. When using WebP, the gpkg_webp extension will be registered. The lossy compression of WebP is used. Note that a recent enough libwebp (>=0.1.4) must be used to support alpha channel in WebP tiles.
PNG8 can be selected to use 8-bit PNG with a color table up to 256 colors. On creation, an optimized color table is computed for each tile. The DITHER option can be set to YES to use Floyd/Steinberg dithering algorithm, which spreads the quantization error on neighbouring pixels for better rendering (note however than when zooming in, this can cause non desirable visual artifacts). Setting it to YES will generally cause less effective compression. Note that at that time, such an 8-bit PNG formulation is only used for fully opaque tiles, as the median-cut algorithm currently implemented to compute the optimal color table does not support alpha channel (even if PNG8 format would potentially allow color table with transparency). So when selecting PNG8, non fully opaque tiles will be stored as 32-bit PNG.
Tiled gridded coverage data
Since GDAL 2.3, tiled gridded coverage data can be stored using PNG unsigned 16bit tiles (with potential offset and scaling so as to be able to represent floating point data) or TIFF 32-bit floating-point LZW compressed tiles.
When converting a GDAL Int16 or UInt16 dataset, PNG tiles will be used. When converting a GDAL Float32 dataset, TIFF tiles will be used by default, unless PNG is explicitly selected, in which case scaling and offsetting will be automatically computed for each tile.
Warning
The tiled gridded extension initially implemented in GDAL 2.2 was not officially adopted and had been later reworked by OGC. The adopted tiled gridded coverage data has a few differences that will make GDAL 2.2 datasets not be compliant with the final extension. GDAL 2.3 can open those GDAL 2.2-generated files.
Tiling schemes
By default, conversion to GeoPackage will create a custom tiling scheme, such that the input dataset can be losslessly converted, both at the pixel and georeferencing level (if using a lossless tile format such as PNG). That tiling scheme is such that its origin (min_x, max_y) in the gpkg_tile_matrix_set table perfectly matches the top left corner of the dataset, and the selected resolution (pixel_x_size, pixel_y_size) at the computed maximum zoom_level of the gpkg_tile_matrix table will match the pixel width and height of the raster.
However to ease interoperability with other implementations, and enable use of GeoPackage with tile servicing software, it is possible to select a predefined tiling scheme that has world coverage. The available tiling schemes are :
GoogleMapsCompatible, as described in WMTS 1.0 specification, Annex E.4. That tiling schemes consists of a single 256x256 tile at its zoom level 0, in EPSG:3857 CRS, with extent in easting and northing in the range [-20037508.34,20037508.34].
InspireCRS84Quad, as described in Inspire View Services. That tiling schemes consists of two 256x256 tiles at its zoom level 0, in EPSG:4326 CRS, with extent in longitude in the range [-180,180] and in latitude in the range [-90,90].
PseudoTMS_GlobalGeodetic, based on the global-geodetic profile of OSGeo TMS (Tile Map Service) specification. This has exactly the same definition as InspireCRS84Quad tiling scheme. Note however that full interoperability with TMS is not possible due to the origin of numbering of tiles being the top left corner in GeoPackage (consistently with WMTS convention), whereas TMS uses the bottom left corner as origin.
PseudoTMS_GlobalMercator, based on the global-mercator profile of OSGeo TMS (Tile Map Service) specification. That tiling schemes consists of four 256x256 tiles at its zoom level 0, in EPSG:3857 CRS, with extent extent in easting and northing in the range [-20037508.34,20037508.34]. The same remark as with PseudoTMS_GlobalGeodetic applies regarding interoperability with TMS.
GoogleCRS84Quad, as described in OGC 07-057r7 WMTS 1.0 specification, Annex E.3. That tiling schemes consists of a single 256x256 tile at its zoom level 0, in EPSG:4326 CRS, with extent in longitude and latitude in the range [-180,180]. Consequently, at zoom level 0, 64 lines are unused at the top and bottom of that tile. This may cause issues with some implementations of the specification, and there are some ambiguities about the exact definition of this tiling scheme. Using InspireCRS84Quad/PseudoTMS_GlobalGeodetic instead is therefore recommended. NOTE: OGC WMTS Simple Profile 13-082r2 changed the definition of GoogleCRS84Quad (so not implemented by the driver). The new definition includes a -1 level (that cannot be modeled in GeoPackage given constraints on zoom_level being positive or 0), with a single tile at origin -180,90 and whose bottom 128 lines are empty. Levels 0 or greater are identical to the InspireCRS84Quad tiling scheme. So for practical purposes, InspireCRS84Quad in GeoPackage is conformant to the new GoogleCRS84Quad definition.
In all the above tiling schemes, consecutive zoom levels defer by a resolution of a factor of two.
Starting with GDAL 3.2, it is also possible to use a Tile Matrix Set definition,
encoded as a JSon file, according to the OGC Two Dimensional Tile Matrix Set standard
Examples of such files can be found at http://schemas.opengis.net/tms/1.0/json/examples/
The GDAL data directory also contains files prefixed with tms_
and with a .json
extension. If there is a tms_FOO.json
file, then FOO
can be used as the
value of the TILING_SCHEME creation option. There are restrictions on the types
of tile matrix set supported:
all zoom levels must have the same origin
consecutive zoom levels defer by a resolution of a factor of two.
all zoom levels must have the same tile dimension
variable matrix width tile set are not supported.
Nodata value
The concept of the nodata value is only supported for tiled gridded elevation datasets. For regular tiled rasters, the alpha band must rather be used.
For Float32 datasets with TIFF tiles, the concepts of nodata in GDAL and null_value in the GeoPackage internals perfectly match.
For Int16, UInt16 or Float32 with PNG tiles, GDAL will generally remap the input nodata value to another value.
On writing, for PNG tiles, the behavior is the following one:
GDAL data type |
Input GDAL nodata value |
null_value in GPKG gpkg_2d_gridded_coverage_ancillary |
Int16 |
Any |
65535 |
UInt16 |
X (if coverage offset == 0 and coverage scale == 1) |
X |
Float32 |
Any |
65535 |
On reading, for PNG tiles, the behavior is the following one:

Creation options
The following creation options are available:
RASTER_TABLE=value: Name of tile user table. By default, based on the filename (i.e. if filename is foo.gpkg, the table will be called "foo").
APPEND_SUBDATASET=[YES/NO]: Defaults to
NO
. If set to YES, an existing GeoPackage will not be priorly destroyed, such as to be able to add new content to it.RASTER_IDENTIFIER=value: Human-readable identifier (e.g. short name), put in the identifier column of the gpkg_contents table.
RASTER_DESCRIPTION=value: Human-readable description, put in the description column of the gpkg_contents table.
BLOCKSIZE=<integer>: Defaults to
256
. Block size in width and height in pixels. Maximum supported is 4096. Should not be set when using a non-customTILING_SCHEME
.BLOCKXSIZE=<integer>: Defaults to
256
. Block width in pixels. Maximum supported is 4096.BLOCKYSIZE=<integer>: Defaults to
256
. Block height in pixels. Maximum supported is 4096.TILE_FORMAT=[PNG_JPEG/PNG/PNG8/JPEG/WEBP/TIFF/AUTO]: Defaults to
AUTO
. Format used to store tiles. See Tile formats.QUALITY=1-100: Defaults to
75
. Quality setting for JPEG and WEBP compression.ZLEVEL=1-9: Defaults to
6
. DEFLATE compression level for PNG tiles.DITHER=[YES/NO]: Defaults to
NO
. Whether to use Floyd-Steinberg dithering (forTILE_FORMAT=PNG8
).TILING_SCHEME=[CUSTOM/GoogleCRS84Quad/GoogleMapsCompatible/InspireCRS84Quad/PseudoTMS_GlobalGeodetic/PseudoTMS_GlobalMercator/other]: Defaults to
CUSTOM
. See Tiling schemes.Starting with GDAL 3.2, the value of TILING_SCHEME can also be the filename of a JSON file according to the OGC Two Dimensional Tile Matrix Set standard, a URL to such file, the radical of a definition file in the GDAL data directory (e.g.
FOO
for a file namedtms_FOO.json
) or the inline JSON definition. Note: the TILING_SCHEME option with a non-CUSTOM value is best used with the gdal_translate utility / CreateCopy() API operation. If used with gdalwarp, it requires setting the -tr switch to the exact value expected by one zoom level of the tiling scheme.ZOOM_LEVEL_STRATEGY=[AUTO/LOWER/UPPER]: Defaults to
AUTO
. Strategy to determine zoom level. Only used by CreateCopy() forTILING_SCHEME
different from CUSTOM. LOWER will select the zoom level immediately below the theoretical computed non-integral zoom level, leading to subsampling. On the contrary, UPPER will select the immediately above zoom level, leading to oversampling. Defaults to AUTO which selects the closest zoom level.RESAMPLING=[NEAREST/BILINEAR/CUBIC/CUBICSPLINE/LANCZOS/MODE/AVERAGE]: Defaults to
BILINEAR
. Resampling algorithm. Only used by CreateCopy() for TILING_SCHEME different from CUSTOM. Defaults to BILINEAR.PRECISION=<floating_point_value_in_vertical_units>: Defaults to
1.0
. Smallest significant value. Only used for tile gridded coverage datasets.UOM=value: Unit of Measurement. Only used for tiled gridded coverage datasets. Also set through SetUnitType()
FIELD_NAME=value: Defaults to
Height
. Field name. Only used for tiled gridded coverage datasets.QUANTITY_DEFINITION=value: Defaults to
Height
. Description of the field. Only used for tiled gridded coverage datasets.GRID_CELL_ENCODING=[grid-value-is-center/grid-value-is-area/grid-value-is-corner]: Grid cell encoding. Only used for tiled gridded coverage datasets. Defaults to grid-value-is-center, when AREA_OR_POINT metadata item is not set.
VERSION=[AUTO/1.0/1.1/1.2/1.3]: Set GeoPackage version (for application_id and user_version fields). In AUTO mode, this will be equivalent to 1.2 starting with GDAL 2.3. 1.3 is available starting with GDAL 3.3
ADD_GPKG_OGR_CONTENTS=[YES/NO]: Defaults to
YES
. Defines whether to add a gpkg_ogr_contents table to keep feature count for vector layers, and associated triggers.
Overviews
gdaladdo / BuildOverviews() can be used to compute overviews. Power-of-two overview factors (2,4,8,16,...) should be favored to be conformant with the baseline GeoPackage specification. Use of other overview factors will work with the GDAL driver, and cause the gpkg_zoom_other extension to be registered, but that could potentially cause interoperability problems with other implementations that do not support that extension.
Overviews can also be cleared with the -clean option of gdaladdo (or BuildOverviews() with nOverviews=0)
Metadata
GDAL uses the standardized gpkg_metadata and gpkg_metadata_reference tables to read and write metadata.
GDAL metadata, from the default metadata domain and possibly other metadata domains, is serialized in a single XML document, conformant with the format used in GDAL PAM (Persistent Auxiliary Metadata) .aux.xml files, and registered with md_scope=dataset and md_standard_uri=http://gdal.org in gpkg_metadata. In gpkg_metadata_reference, this entry is referenced with a reference_scope=table and table_name={name of the raster table}
It is possible to read and write metadata that applies to the global GeoPackage, and not only to the raster table, by using the GEOPACKAGE metadata domain.
Metadata not originating from GDAL can be read by the driver and will be exposed as metadata items with keys of the form GPKG_METADATA_ITEM_XXX and values the content of the metadata columns of the gpkg_metadata table. Update of such metadata is not currently supported through GDAL interfaces ( although it can be through direct SQL commands).
The specific DESCRIPTION and IDENTIFIER metadata item of the default metadata domain can be used in read/write to read from/update the corresponding columns of the gpkg_contents table.
You can set the CREATE_METADATA_TABLES configuration option to NO to avoid creating and filling the metadata tables.
IMAGE_STRUCTURE metadata item
Note
Implementation details, normally transparent to GDAL users, but useful for other implementations.
Starting with GDAL 3.6.1, the following optional metadata items can be read and
write into the IMAGE_STRUCTURE
metadata domain, in the
<GDALMultiDomainMetadata>
XML element:
BAND_COUNT=1, 2, 3 or 4. Applies only for Byte data. Set when creating a dataset so that GDAL knows the number of bands when reopening it.
COLOR_TABLE={{r0,g0,b0,a0},...{r255,g255,b255,a255}}. Applies only for Byte data and a single band dataset. Set when creating a dataset from a source dataset that has a color table.
TILE_FORMAT=PNG/PNG8/PNG_JPEG/JPEG/WEBP. Set when creating a dataset so that GDAL knows the tile format when reopening it, for updates.
NODATA_VALUE=integer between 0 and 255. Applies only for Byte data.
Example:
INSERT INTO gpkg_metadata VALUES(
1,
'dataset',
'http://gdal.org',
'text/xml',
'<GDALMultiDomainMetadata><Metadata domain="IMAGE_STRUCTURE"><MDI key="BAND_COUNT">1</MDI><MDI key="NODATA_VALUE">255</MDI></Metadata></GDALMultiDomainMetadata>')
);
INSERT INTO gpkg_metadata_reference VALUES(
'table','my_raster_table',NULL,NULL,'2022-11-09T18:44:59.723Z',1,NULL);

Translation of a GeoTIFF into GeoPackage using GoogleMapsCompatible tiling scheme (with reprojection and resampling if needed)
gdal_translate -of GPKG byte.tif byte.gpkg -co TILING_SCHEME=GoogleMapsCompatible
Building of overviews of an existing GeoPackage, and forcing JPEG tiles
gdaladdo -r cubic -oo TILE_FORMAT=JPEG my.gpkg 2 4 8 16 32 64
Addition of a new subdataset to an existing GeoPackage, and choose a non default name for the raster table.
gdal_translate -of GPKG new.tif existing.gpkg -co APPEND_SUBDATASET=YES -co RASTER_TABLE=new_table
Reprojection of an input dataset to GeoPackage
gdalwarp -of GPKG in.tif out.gpkg -t_srs EPSG:3857
Open a specific raster table in a GeoPackage
gdalinfo my.gpkg -oo TABLE=a_table
Raster SQL functions
The raster SQL functions mentioned at Raster related functions are also available.
The gdal_get_layer_pixel_value()
function (added in GDAL 3.7), variant of the
generic gdal_get_pixel_value()
, can be used to extract the value of a pixel
in a raster layer of the current dataset.
It takes 5 arguments:
a string with the layer/table name
a band number (numbering starting at 1)
a string being "georef" to indicate that subsequent values will be georeferenced coordinates, or "pixel" to indicate that subsequent values will be in column, line pixel space
georeferenced X value or column number
georeferenced Y value or line number
SELECT gdal_get_layer_pixel_value('my_raster_table', 1, 'georef', 440720, 3751320)
SELECT gdal_get_layer_pixel_value('my_raster_table', 1, 'pixel', 0, 0)

Varnish 5.0 changes some (mostly) internal APIs and adds some major new features over Varnish 4.1.
Varnish 5.0 supports jumping from the active VCL's vcl_recv{} to another VCL via a VCL label.
The major use of this will probably be to have a separate VCL for each domain/vhost, in order to untangle complex VCL files, but it is not limited to this criteria, it would also be possible to send all POSTs, all JPEG images or all traffic from a certain IP range to a separate VCL file.
VCL labels can also be used to give symbolic names to loaded VCL configurations, so that operations personnel only need to know about "normal", "weekend" and "emergency", and web developers can update these as usual, without having to tell ops what the new weekend VCL is called.
We are in the process of adding HTTP/2 support to Varnish, but the code is very green still - life happened.
But you can actually get a bit of traffic though it already, and we hope to have it production ready for the next major release (2017-03-15).
Varnish supports HTTP/1 -> 2 upgrade. For political reasons, no browsers support that, but tools like curl does.
For encrypted HTTP/2 traffic, put a SSL proxy in front of Varnish.
HTTP/2 support is disabled by default, to enable, set the http2 feature bit.
We have added to the directors VMOD an overhauled version of a director which was available as an out-of-tree VMOD under the name VSLP for a couple of years: It's basically a better hash director, which uses consistent hashing to provide improved stability of backend node selection when the configuration and/or health state of backends changes. There are several options to provide the shard key. The rampup feature allows to take just-gone-healthy backends in production smoothly, while the prewarm feature allows to prepare backends for traffic which they would see if the primary backend for a certain key went down.
It can be reconfigured dynamically (outside vcl_init{}), but different to our other directors, configuration is transactional: Any series of backend changes must be concluded by a reconfigure call for activation.
Almost since the beginning of time (2008), varnish has hit-for-pass: It is basically a negative caching feature, putting into the cache objects as markers saying "when you hit this, your request should be a pass". The purpose is to selectively avoid the request coalescing (waitinglist) feature, which is useful for cacheable content, but not for uncacheable objects. If we did not have hit-for-pass, without additional configuration in vcl_recv, requests to uncacheable content would be sent to the backend serialized (one after the other).
As useful as this feature is, it has caused a lot of headaches to varnish administrators along the lines of "why the beep doesn't Varnish cache this": A hit-for-pass object stayed in cache for however long its ttl dictated and prevented caching whenever it got hit ("for that url" in most cases). In particular, as a pass object can not be turned into something cacheable retrospectively (beresp.uncacheable can be changed from false to true, but not the other way around), even responses which would have been cacheable were not cached. So, when a hit-for-pass object got into cache unintentionally, it had to be removed explicitly (using a ban or purge).
We've changed this now:
A hit-for-pass object (we still call it like this in the docs, logging and statistics) will now cause a cache-miss for all subsequent requests, so if any backend response qualifies for caching, it will get cached and subsequent requests will be hits.
In short: We've changed from "the uncacheable case wins" to "the cacheable case wins" or from hit-for-pass to hit-for-miss.
The primary consequence which we are aware of at the time of this release is caused be the fact that, to create cacheable objects, we need to make backend requests unconditional (that is, remove the If-Modified-Since and If-None-Match headers): For conditional client requests on hit-for-pass objects, Varnish will now issue an unconditional backend fetch and, for 200 responses, send a 304 or 200 response to the client as appropriate.
As of the time of this release we cannot say if this will remain the final word on this topic, but we hope that it will mean an improvement for most users of Varnish.
We have made the ban lurker even more efficient by example of some real live situations with tens of thousands of bans using inefficient regular expressions.
The new parameter ban_lurker_holdoff tells the ban lurker for how long it should get out of the way when it could potentially slow down lookups due to lock contention. Previously this was the same as ban_lurker_sleep.
Previously, we would only send a request body for passed requests (and for pipe mode, but this is special anyway and should be avoided).
Not so any more, but the default behaviour has not changed:
Whenever a request has a body, it will get sent to the backend for a cache miss (and pass, as before). This can be prevented by an unset bereq.body and the builtin.vcl removes the body for GET requests because it is questionable if GET with a body is valid anyway (but some applications use it).
So the often-requested ability to cache POST/PATCH/... is now available, but not out-of-the-box:
To summarize: You should know what you are doing when caching anything but a GET or HEAD and without creating an appropriate cache key doing so is almost guaranteed to be wrong.
Previously, ESI subrequests depending on objects being fetched from the backed used polling, which typically added some ~5ms of processing time to such subrequests and could lead to starvation effects in extreme corner cases.
The waitinglist logic for ESI subrequests now uses condition variables to trigger immediate continuation of ESI processing when an object being waited for becomes available.
Are now supported through the .proxy_header attribute of the backend definition.
For default builds, vcl files are now also being looked for under /usr/share/varnish/vcl if not found in /etc/varnish.
For custom builds, the actual search path is ${varnishconfdir}:${datarootdir}/varnish/vcl
The basic device detection vcl is now bundled with varnish.

Success stories:
Dialogue Education is a unique synthesis of the key insights of how adults learn that can be applied to improve any training curriculum.Our clients find that our Dialogue Education approach to learning design and facilitation helps them in creating participatory learning events (workshops, trainings, seminars, capacity building events, public engagement events) that are engaging and energizing, yet rigorous and effective.
The approach has helped them to name what makes for effective learning, and to do it more consistently in how they design curriculum and train.
As well, Dialogue Education has helped them to develop a common philosophy, language and approach to learning design and facilitation that has helped staff to work together and to create transparent, readily transferrable training materials.
Testimonial:
Ouida Cooper Rodriguez, Training Director, Women's InitiativeDialogue Education is a powerful tool for organizations, clients and staff. It gives a framework for empowering clients and creating a safe, inclusive environment. For organizations, it provides a sound structure for program development, as well as staff development and communication. It gives each person a voice to bring all of themselves to a process. It is powerful when an entire organization comes from this empowerment model.
As a consultant and facilitator for almost 10 years, this work has enriched my skills and has given me the terms and concrete concepts for what I have been doing intuitively for years. I am even more conscious and aware of every aspect of "learner as decision maker." The Seven Steps of Design have been particularly valuable for me.
When put into active practice, these principles can transform lives and organizations. This training is priceless! It is an investment worth every dollar. The results will speak for themselves!

"Last week I had the opportunity to attend a CRWRC training event led by two GLP Certified Teachers in Choluteca, Honduras. I just wanted to let you know what a wonderful event it was! I was a high school teacher before I attended seminary and I am a big fan of Jane Vella / Global Learning Partners adult education. This event... reflected the best of adult education. People were involved in many meaningful small group tasks, time was managed well, leaders provided many opportunities for input from participants, the process of the workshop itself was evaluated periodically and feed-back was helpful and presented in a non-threatening way."
