The web, once broken down, is a very simple mechanism. The user (you and I) send a request through the computer and its browser to the server through the internet using HTTP. The Server then send the requested information back through the internet to your browser, through he use of HTML documents. The browser then interprets this and displays it on the computers screen.
HTML or Hypertext Markup Language is the heart of the web. Within a HTML document you have text content, which describes "what you see" and markup which is the "how you see it". HTML also includes references to other documents, such as images and videos , as well as links to other pages, like this one.
HTML documents are made up of elements. The basic structure of a element is the HTML tag its content and the closing tag.
 It rather refers to the simple fact that a computer does exactly as its being told to. There is no thought process of its own to interpret what the user really wants it to do.
A HTML element can either be inline, where the tag is actually within the content, or block, where it creates and ivsible box around its contents.
Developer tools can be brought up in the browser to allow the user to view that webpages coding. This is helpful in the sense that you can learn from everyone, everywhere. If you see something tat a web page has that you would like to learn, you can simply open the developer tools and read the coding.
This idea stems from the fact that an element can contain multiple elements inside of it. This is similar to a actual tree because it creates a branching effect within the coding itself. Simply, there are boxes inside of boxes inside of boxes.
Everything, an I mean everything, in HTML coding is in boxes. You see a circle? It's a box. You see a tringle? It's a box. This is really good because it makes it easy to structure and design a web page easily. With everything in boxes all you have to do is great a gride to neatly align and center your page with structure.
Sublime and scratchpad are just a couple of examples of text editors. These programs help make life easier for programing by doing things such as automatically creating the closing tag.
Avoiding repetition is important for a variety of reasons.
Avoiding Errors: When programmers don't avoid repetition, they will often have to do the same thing over and over. This may mean copy and pasting certain style attributes into many HTML elements or rewriting the same code (sometimes with minor differences) many times. This can lead to errors when the programmer decides to make a change to something. If they don't dilligently make that same change everywhere the repeated code appears, problems will arise.
Consistency: In this web page, I wanted every lesson to look the same. Instead of manually giving each one the same style, I was able to assign each lesson div the same class and then specify the style for that class in only one place! By avoiding repetion, it's now very easy for me to make changes to this style.
CSS stands for Cascading Style Sheets and they give programmers a way to control the style of related HTML elements. This is done by giving similar HTML elements the same class name and then specifying the style that should apply to that class.


I love learning!
I'm good at communicating with children!
I love learning langueages and practicing them while thavelling or work!

Jarvis is an open-source assistant, listening to your orders from any service.
Asciinema? YouTube?
--- layout: landing_page title: Control anything from any service css: home ---
Asciinema? YouTube?
Jarvis relies on addons.
There are 3 different types: sources, receivers and clients.
Sources are feeding Jarvis with data.
It can be a Tweet, a picture from Instagram, an email, or even a pressed button. Sky is the limit! If you can retrieve data from a service, an object, then it can become a source.
Receivers are handling data. They are waiting to be triggered.
What about publishing every Instagram pic you post on Tumblr, saving them in local, and sending it to your mum via mail? Or receiving a failed notification from Travis-CI, playing an alarm sound on your computer/homeserver, and blinking every Philips Hue in your house/office?
Clients are the gate between sources and receivers.
They are used by receivers to emit something. If you need to tweet anything, you don't have to create a way to do it in the receiver, there is probably a client to do that. You can find different clients: Twitter, Tumblr, Instagram, but also Philips Hue, speakers... Anything with an input can become a client.
$ git clone https://github.com/Jarvis-Bot/Jarvis-Core.git Jarvis
$ export PATH=Jarvis/bin:$PATH
$ jarvis addons install
$ jarvis
Now that Jarvis is successfully installed, you can look for addons on Github, or craft your owns!
Don't forget to put this at the end of your .bashrc / .zshrc file :
export PATH=[PATH/TO/JARVIS/FOLDER]/bin:$PATH


Google’s free Wi-Fi tested – Here are the real speeds
by Jan VermeulenGoogle has launched free Wi-Fi hotspots for the residents of several communities in the Cape Flats through its Google Station programme.
The hotspots were launched in partnership with Think WiFi. Google told MyBroadband in an interview that each hotspot has 100Mbps of either fibre or microwave backhaul, depending on what is available.
Other than a renewable session limit of 30 minutes, Google said there are no other restrictions on usage at its Station hotspot.
Each site can cover 40–60 meters, though some are configured in a mesh to provide bigger hotspots around certain areas. At last count, there were around 28,000 people per day using Google Station in the Western Cape.
Townships covered include Langa, Ruyterwacht, Elsies Rivier, Guguletu, Khayelitsha, Delft, and Philippi.
We were recently in Cape Town as part of our quarterly mobile network quality testing, and we decided to stop in Langa for a few minutes to test Google Station.
Our tests were conducted outside Lelalpa Restaurant in Langa, using a laptop with a built-in dual-band 802.11ac Wi-Fi radio.
The screenshots below show the process of connecting to the hotspot, followed by our test results.
Connecting to Google Station
The Google Station captive portal displays a loading screen, then presents a “Connect” button.
Watch an ad
Before you are connected to the Internet, you are played a video advertisement. Telkom and Showmax are the two first advertising partners for Station in South Africa, Google said.
Get more time by watching more ads
Each session on Google Station is 30 minutes long. To extend the session or reconnect, you can elect to watch another video ad.
Google Station Wi-Fi settings
The laptop we performed our tests with connected to the Google Station hotspot in 802.11n mode. According to the operating system, a maximum speed of over 100Mbps was possible.
Test results
Speed tests to MyBroadband’s server at NAPAfrica in Cape Town achieved download speeds of 1Mbps, and upload speeds of around 0.7Mbps.
Trying to download a large file, like an installation image for Ubuntu Linux, achieved only a fraction of that speed. At most, our downloads ran at speeds of 200kbps.
Despite problems with throughput on downloads, other services appeared to work well enough. We were able to watch a YouTube video from the Crash Course channel while browsing Wikipedia.
However, Khan Academy and Coursera were unusably slow.


Greta Thunberg to set sail for Europe after climate talks relocated
Swedish climate activist Greta Thunberg is due to set sail across the Atlantic for the second time in a few months on Wednesday.
Ms Thunberg travelled from Europe to the United States across the ocean for the UN’s Climate Action Summit in New York and was due to attend a global climate meeting in Santiago, Chile, in December.
But Chile cancelled at short notice and the meeting moved to Spain, forcing the 16-year-old to look for a way to head back to Europe.
She will leave on La Vagabonde, a 15-metre long catamaran whose green credentials include solar panels and hydro-generators for power.
It also has a toilet, unlike the boat on which she sailed from the United Kingdom to New York in August.
“There are countless people around the world who don’t have access to a toilet,” she said about the upgrade. “It’s not that important. But it’s nice to have.”
The owners of the boat are Riley Whitelum and Elayna Carausu, an Australian couple who have an 11-month-old son named Lenny.
The family, which has a large online following, responded to Ms Thunberg’s call on social media for a carbon-free ride to Europe while an expert sailor, Nikki Henderson, is also coming along.
The trip could take two to four weeks, and November is considered off-season for sailing across the Atlantic.
As Ms Thunberg spoke on Tuesday in Hampton, Virginia, the temperature had dipped to around 4C as sleet turned into light snow.
But the Swede, who refuses to fly because of the carbon price of plane travel, did not seem bothered.
“I’m looking forward to it, just to be able to get away and recap everything and to just be disconnected,” she said.
Ms Thunberg just finished a nearly three-month trip through North America, where she gave an impassioned speech before the United Nations and took part in climate strike rallies and protests from California to Colorado to North Carolina.
It should be the adults who take that responsibility. But it feels like the adults and the people in power today are not.
She has become a symbol of a growing movement of young climate activists after leading weekly school strikes in Sweden that inspired similar actions in about 100 cities worldwide.
She has also drawn criticism from conservative commentators in the US as well as Russian President Vladimir Putin.
But she brushed off the criticism during her round of back-to-back interviews in the catamaran on Tuesday.
“It should be the adults who take that responsibility,” she said. “But it feels like the adults and the people in power today are not.”
When she looks back on her time in the US and Canada, Ms Thunberg said the things that stick out the most include a glacier in Canada’s Jasper National Park that is destined to disappear “no matter what we do”.
She also was surprised at how much she was recognised.
“There are always people who come up to me and ask for selfies and so on,” she said.

blockmatrix: blockmatrix: Tools to solve algebraic systems with partitioned
matrices
Some elementary matrix algebra tools are implemented to manage
block matrices or partitioned matrix, i.e. "matrix of matrices"
(http://en.wikipedia.org/wiki/Block_matrix). The block matrix is here
defined as a new S3 object. In this package, some methods for "matrix"
object are rewritten for "blockmatrix" object. New methods are implemented.
This package was created to solve equation systems with block matrices for
the analysis of environmental vector time series .
Bugs/comments/questions/collaboration of any kind are warmly welcomed.

Entering 1 will cause no change;
entering 2 will make every interval twice as large.
This will add a random amount of detuning to each note of the scale.
Select a subset from the current scale.
Select a ratio that approximates the interval.
Note: if you enter an odd number, the interval of equivalence will change (e.g. mistuned octaves)
Divides your interval of equivalence into an equal number of steps, then rounds each interval in your scale to the nearest equal step.
 Intervals in your scale which are larger than the modulus will wrap around, leaving only a remainder.
Rotates the mode of your scale.
The resulting scale will be sorted ascendingly.
Select the options for the note map.

Remove surrounding $() to avoid executing output (or use eval if intentional).
if $(which epstopdf)
then
echo "Found epstopdf"
fi
or
make_command() {
printf 'cat header %q footer > %q\n' "$1" "$2" | tee log
}
$(make_command foo.html output/foo.html)
if which epstopdf
then
echo "Found epstopdf"
fi
or
make_command() {
printf 'cat header %q footer > %q\n' "$1" "$2" | tee log
}
eval "$(make_command foo.html output/foo.html)"
ShellCheck has detected that you have a command that just consists of a command substitution. This often happens when you want to run a command (possibly from a variable name), without realizing that $(..)
is for capturing and not for executing.
For example, if you have this shell function:
sayhello() { echo "hello world"; }
Then $(sayhello)
will:
sayhello
, capturing "hello world"hello world
, resulting in bash: hello: command not found
Meanwhile, just sayhello
will:
sayhello
, outputting "hello world" to screenNote that this is equally true if the command is in a variable, e.g. x=sayhello; $($x)
.
If you do have a command that outputs a second command, similar to how ssh-agent
outputs export
commands to run, then you should do this via eval
. This way, quotes, pipes, redirections, semicolons, and other shell constructs will work as expected. Note that this kind of design is best avoided when possible, since correctly escaping all values can be difficult and error prone.

University students whose personal details were emailed to hundreds of their classmates have been paid more than £140,000 in compensation.
A spreadsheet containing student health problems, bereavements and personal issues was sent to 298 people at the University of East Anglia in June 2017.
Insurers have since paid out £142,512 to affected students from UEA, which said it had reviewed data practices. The Information Commissioner said at the time no further action was needed. One affected student, who asked to remain anonymous, said the figure was "a lot of money" but she was not "massively shocked" given the scale and sensitivity of the breach.
She highlighted subsequent data-management mistakes at the university, adding: "You'd think leaking private medical history, the names of sexual assault victims and personal family traumas just once would be enough to learn the lesson and move on." 'Life on show'
The compensation payouts were revealed through a Freedom of Information Act release reported by student newspaper Concrete. Ian Callaghan, chief resource officer and university secretary at UEA, said "great strides" had been made in raising awareness of data management since the breach.
He said all data on hard and shared drives had been reviewed, mandatory data protection training had been introduced and access to group email accounts had been limited.
The offending email, sent to all American Studies students at the Norwich-based university, contained personal data relating to 191 undergraduates.
It listed extenuating circumstances in which essay extensions and other concessions were granted. Students described how they felt their "life was on show".
The Information Commissioner's Office, which investigates data breaches and can fine serious offenders, said the breach did not meet the requirements for regulatory action.
The UEA's own report into the breach found its attempts to contain the damage had been "timely and appropriate" and it had tightened procedures.
The following November, an urgent investigation was launched after personal details about a UEA staff member were sent to 300 people.


Didier Drogba sends message to Chelsea FC striker Tammy Abraham
Didier Drogba has a special message for Tammy Abraham after the Chelsea FC striker netted his first goal for England
by Social SpyDidier Drogba has taken to social media to pay tribute to Tammy Abraham after the Chelsea FC striker scored his first goal for England last week.
The 22-year-old has made a brilliant start to the new season with Chelsea FC and has been a regular fixture in the first team under Frank Lampard.
Abraham has scored an impressive 10 goals and made two assists in the Premier League for Lampard’s men this season to help the Blues up into third place in the table.
The young striker’s fine form has earned him a spot in Gareth Southgate’s England side and the forward came off the bench to score in the Three Lions’ 7-0 thrashing of Montenegro at Wembley on Thursday night.
Chelsea FC posted about Abraham’s England goal after the game on the club’s official Instagram account, and Blues legend Drogba left a comment under the photo.
Drogba wrote in the comment: “Waaw!!!! Tammy Abraham, so proud of you!!! Congrats son.”
Chelsea FC fans will be hoping to see Abraham continue his fine form for the Blues when they take on Manchester City at The Etihad on Saturday evening.
The Blues are aiming to maintain their spot in the top four this season and they currently find themselves eight points behind leaders Liverpool FC.


Edges, lines and scaffolds
A DISCOVAR de novo assembly is a graph whose edges represent DNA
sequences. Within any assembly one can find regions that are essentially linear.
We call these lines. Here is an example:
This line has four cells. In this case, for each cell, there
are two paths across the cell, except for the third cell, which has three.
Any line can be completely linearized by replacing each cell by parallel
edges (representing the paths across it), like this:
Multiple paths within a cell may reflect biological differences, such as
heterozygous sites, or somatic mutations. Similarly a line could represent
multiple, highly similar loci (which would be reflected in the observed copy
number). Partial phasing will sometimes lead to more than two paths.
However multiple paths can also represent non-biological differences,
such as those arising at loci that are very hard to sequence, and for which
consequently the assembly is unable to determine the exact sequence, instead
providing alternatives.
We allow cells having no paths across, representing captured gaps, and
displayed in files below using 100 Ns.
DISCOVAR de novo assemblies are symmetric: for each edge, there is
a reverse complement edge, and for each line, there is a reverse complement line.
DISCOVAR de novo provides several output forms from which you
can select:
- a.fasta = fasta file of edges
- a.lines = binary file of lines, mathematically a
vec<vec<vec<vec<int>>>>, in which the ints are edge ids
- a.lines.efasta* = standard scaffold efasta file, which shows {s1,...,sn}
for the ALTERNATIVES associated to a given cell
- a.lines.fasta* = standard scaffold fasta file, obtained by taking the FIRST
path through each cell; LOSES INFORMATION
- a.lines.src = human-readable form of a.lines, represented using nested
brackets {...}
* 'Duplicate' reverse complement lines have been removed from these files.
Also for circular chromosomes or episomes, the header line is labeled
'circular' and the ends of the sequence overlap by exactly K-1 bases (K = 200).
We invite requests for alternative forms.

And if you had tried to make a mutual appointment, you would certainly have broken away from the appointment, but -- in order that Allah might bring about a matter which had to be done; that he who perished by clear argument might perish, and he who lived by clear argument might live. And surely Allah is Hearing, Knowing: |
| 008:042 Pickthal | : |
When ye were on the near bank (of the valley) and they were on the yonder bank, and the caravan was below you (on the coast plain). And had ye trysted to meet one another ye surely would have failed to keep the tryst, but (it happened, as it did, without the forethought of either of you) that Allah might conclude a thing that must be done; that he who perished (on that day) might perish by a clear proof (of His Sovereignty) and he who survived might survive by a clear proof (of His Sovereignty). Lo! Allah in truth is Hearer, Knower. |
| 008:042 Rashad | : |
Recall that you were on this side of the valley, while they were on the other side. Then their caravan had to move to lower ground. Had you planned it this way, you could not have done it. But GOD was to carry out a predetermined matter, whereby those destined to be annihilated were annihilated for an obvious reason, and those destined to be saved were saved for an obvious reason. GOD is Hearer, Omniscient. |
| 008:042 Sarwar | : |
Recall when your army was positioned at the less defensible brink of the valley, (the pagans') army had the more defensible higher side of the valley and the caravan was led (out of your reach) below. This situation did not take place according to your previous plans, otherwise, everything would have been different. (It was God's plan ) to place you in a vulnerable position, exposed to the enemy and it was His plan to lead the caravan out of your reach) so that His decree that you would be granted a victory by a miracle would become a doubtless fact and so that those who were to be destroyed would face destruction with a clear knowledge of the Truth and those who were to survive would also survive with a clear knowledge of the Truth. God is All-hearing and All-knowing. |
| 008:042 Shakir | : |
When you were on the nearer side (of the valley) and they were on the farthest side, while the caravan was in a lower place than you; and if you had mutually made an appointment, you would certainly have broken away from the appointment, but-- in order that Allah might bring about a matter which was to be done, that he who would perish might perish by clear proof, and he who would live might live by clear proof; and most surely Allah is Hearing, Knowing; |
| 008:042 Sherali | : |
When you were on the nearer bank of the Valley, and they were on the further bank, and the caravan was below you. And if you had to make an appointment between you, you would have certainly differed with regard to the time of the appointment. But the encounter was brought about without appointment that ALLAH might accomplish the thing that was decreed, so that he, who had already perished by a clear proof, should perish, and he, would had already come to life by a clear proof, should live. And certainly ALLAH is All-Hearing, All-Knowing. |
| 008:042 Yusufali | : |
Remember ye were on the hither side of the valley, and they on the farther side, and the caravan on lower ground than ye. Even if ye had made a mutual appointment to meet, ye would certainly have failed in the appointment: But (thus ye met), that Allah might accomplish a matter already enacted; that those who died might die after a clear Sign (had been given), and those who lived might live after a Clear Sign (had been given). And verily Allah is He Who heareth and knoweth (all things). |

Top 6 scheduling tips
I’m someone who LOVES to stay organized and keeping my schedule in order is a big part of
that. Managing your schedule can definitely be difficult as a busy university student,
but it’s also such an important skill to master. I’ve compiled a list of tips that I’ve
found helpful for managing my time in my five (!) years as a UVic student.
1.Use a scheduling tool.
I’m not particularly good at keeping track of anything in my head, so it’s important that it
all gets written down. I prefer to maintain my schedule in a hard-copy planner; there is
something about physically dividing up my time onpaper that really works for me. Plus, my
paper planner won’t ever run out of battery!
2.Write down important deadlines on the first day of class.
On the first day of class, students receive a syllabus, or course outline, which contains
important dates and deadlines. As soon as I receive my syllabus, I transfer all of these dates
into my planner, taking note of particularly busy periods and any potential conflicts. If I’m still “course shopping”,
or finalizing which courses I’m going to take, timing may influence my decision.
3.Use colour.
At the beginning of each term, I assign each class a certain colour of highlighter. After
writing down important deadlines, I highlight each with the corresponding colour for that
class. Highlighting makes those important dates really stand out, ensuring the deadline
doesn’tcreep up on me and allows me to note key points in the term for each class.
4.Schedule all commitments.
I use my planner to schedule all activities that I have each day, both for school and my
life outside of school. I allot chunks of time for class, meetings, work, coffee with friends,
or anything else that I may have planned. Even if the activity is routine (for example, I have
class every Monday and Thursday at 10 a.m.), I still take note of it. This makes
it very easy for me to see, at a glance, what my day looks like and when I have free time.
Whew, I think that’s it! I’ll admit that I can be more than a little intense about my
organization,but this combination of methods has never failed me!

- class dscribe.core.lattice.Lattice(matrix)[source]¶
Bases:
object
A lattice object. Essentially a matrix with conversion matrices. In general, it is assumed that length units are in Angstroms and angles are in degrees unless otherwise stated.
Create a lattice from any sequence of 9 numbers. Note that the sequence is assumed to be read one row at a time. Each row represents one lattice vector.
- Parameters
matrix – Sequence of numbers in any form. Examples of acceptable input. i) An actual numpy array. ii) [[1, 0, 0], [0, 1, 0], [0, 0, 1]] iii) [1, 0, 0 , 0, 1, 0, 0, 0, 1] iv) (1, 0, 0, 0, 1, 0, 0, 0, 1) Each row should correspond to a lattice vector. E.g., [[10, 0, 0], [20, 10, 0], [0, 0, 30]] specifies a lattice with lattice vectors [10, 0, 0], [20, 10, 0] and [0, 0, 30].
- property abc¶
Lengths of the lattice vectors, i.e. (a, b, c)
- get_cartesian_coords(fractional_coords)[source]¶
Returns the cartesian coordinates given fractional coordinates.
- Parameters
fractional_coords (3x1 array) – Fractional coords.
- Returns
Cartesian coordinates
- get_fractional_coords(cart_coords)[source]¶
Returns the fractional coordinates given cartesian coordinates.
- Parameters
cart_coords (3x1 array) – Cartesian coords.
- Returns
Fractional coordinates.
- get_points_in_sphere(frac_points, center, r, zip_results=True)[source]¶
Find all points within a sphere from the point taking into account periodic boundary conditions. This includes sites in other periodic images.
Algorithm:
place sphere of radius r in crystal and determine minimum supercell (parallelpiped) which would contain a sphere of radius r. for this we need the projection of a_1 on a unit vector perpendicular to a_2 & a_3 (i.e. the unit vector in the direction b_1) to determine how many a_1”s it will take to contain the sphere.
Nxmax = r * length_of_b_1 / (2 Pi)
keep points falling within r.
- Parameters
frac_points – All points in the lattice in fractional coordinates.
center – Cartesian coordinates of center of sphere.
r – radius of sphere.
zip_results (bool) – Whether to zip the results together to group by point, or return the raw fcoord, dist, index arrays
- Returns
- [(fcoord, dist, index) …] since most of the time, subsequent
processing requires the distance.
- else:
fcoords, dists, inds
- Return type
if zip_results
- property inv_matrix¶
Inverse of lattice matrix.
- property lengths¶
- property matrix¶
Copy of matrix representing the Lattice
- property reciprocal_lattice¶
Return the reciprocal lattice. Note that this is the standard reciprocal lattice used for solid state physics with a factor of 2 * pi. If you are looking for the crystallographic reciprocal lattice, use the reciprocal_lattice_crystallographic property. The property is lazily generated for efficiency.
- property reciprocal_lattice_crystallographic¶
Returns the crystallographic reciprocal lattice, i.e., no factor of 2 * pi.

Pompeo says NATO needs to change, or risk becoming obsolete
BERLIN (Reuters) - NATO needs to grow and change or else the alliance runs the risk of becoming obsolete, U.S. Secretary of State Mike Pompeo said on Friday.
“Seventy years on NATO now, it needs to grow and change. It needs to confront the realities of today and the challenges of today,” Pompeo said during a question and answer session after giving a speech in Berlin.
“If nations believe that they can get the security benefit without providing NATO the resources that it needs, if they don’t live up to their commitments, there is a risk that NATO could become ineffective or obsolete,” he added.


Install DDC in a sandbox for evaluation
Estimated reading time: 11 minutesThese are the docs for UCP version 1.1
To select a different version, use the selector below.
This page introduces Docker Datacenter (also known as DDC): a combination of Docker Universal Control Plane (UCP) and Docker Trusted Registry (DTR), and walks you through installing it on a local (non-production) host or sandbox. Once you’ve installed, we also give you a guided tour so you can evaluate its features.
The instructions here are for a sandbox installation on Mac OS X or Windows systems. If you’re an experienced Linux user, or if you want more detailed technical information, you might want to skip this evaluation and go directly to Plan a production installation and then to Install UCP for production.
Note: This evaluation installs using the open source software version of Docker Engine inside of a VirtualBox VM which runs the small-footprint
boot2docker.iso
Linux. This configuration is not a production configuration.
Introduction: About this example
In this tutorial, we use Docker’s provisioning tool - Docker Machine - to
create two virtual hosts. These two hosts are VirtualBox VMs running a small
footprint Linux image called boot2docker.iso
, with the open source version of
Docker Engine installed.
A UCP installation consists of an UCP controller and one or more hosts. We install UCP on one host, then join the second node to UCP as a swarm member. The two VMs create a simple swarm cluster with one controller, which by default secures the cluster via self-signed TLS certificates.
DDC’s second component is DTR, which must be installed on a host that’s a member of the UCP swarm. So next, we install DTR on that second node.
Once you’ve installed UCP and DTR, use this tutorial to deploy a container through UCP, and explore the user interface.
Note: The command examples in this page were tested for a macOS environment. If you are in another, you may need to adjust to use analogous commands for your environment.
Verify the prerequisites
This example requires that you have:
- Docker Toolbox installed (contains Docker Machine and Docker Engine)
- A free Docker ID account
Step 1: Provision hosts with Engine
In this step, you provision two VMs for your UCP sandbox installation. One will run UCP and one will be used to run containers, so the host specifications will be slightly different.
In a production environment you would use enterprise-grade hosts instead of local VMs. These nodes could be on your company’s private network or in the cloud. You would also use the Commercially Supported (CS Engine) version of Docker Engine required by UCP.
Set up the nodes for your evaluation:
-
Open a terminal on your computer.
-
Use Docker Machine to list any VMs in VirtualBox.
$ docker-machine ls NAME ACTIVE DRIVER STATE URL SWARM default * virtualbox Running tcp://<IP_ADDRESS>:2376
-
Create a VM named
node1
using the following command.$ docker-machine create -d virtualbox \ --virtualbox-memory "2500" \ --virtualbox-disk-size "5000" node1
When you create your virtual host you specify the memory and disk size options. UCP requires a minimum of 3.00 GB disk space and runs best with a minimum of 2 GB of memory.
-
Create a VM named
node2
using the command below.$ docker-machine create -d virtualbox \ --virtualbox-memory "2500" \ --virtualbox-disk-size "5000" node2
-
Use the
docker-machine ls
command to list your hosts.$ docker-machine ls NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS default - virtualbox Stopped Unknown node1 - virtualbox Running tcp://<IP_ADDRESS>:2376 v1.12.1 node2 - virtualbox Running tcp://<IP_ADDRESS>:2376 v1.12.1
At this point, both nodes are in the
Running
state and ready for UCP installation.
About the ucp tool
To install UCP, use the Docker CLI to pull and run the docker/ucp
image, which contains a bootstrapper tool designed to make UCP easier
to install than many enterprise-grade applications. The ucp
tool runs
docker run
commands to install
a UCP controller or join
a node to a UCP
controller.
The general format of these commands is docker run --rm -it docker/ucp
with
one or more subcommands, which are discussed later in this document. For this
tutorial, we use the -i
option for “interactive” install mode, but
you can run these commands without -i
(unattended) in production.
Regardless of how you use the docker/ucp
tool, the default install supplies
default options for both data volumes and the certificate authority (CA). In a
production installation you can also optionally:
- use the high availability feature
- customize the port used by the UCP web application
- customize the port used by the Swarm manager
- create your own data volumes
- use your own TLS certificates
You can learn more about these when you plan a production installation.
Step 2. Install the UCP controller
In this step, you install the UCP controller on the node1
you provisioned
earlier. A controller serves the UCP application and runs the processes that
manage an installation’s Docker objects.
In a production installation, a system administrator can set up UCP’s high availability feature, which allows you to designate several nodes as controller replicas. This way if one controller fails, a replica node is ready to take its place.
For this sandbox installation, we don’t need high availability, so a single host for the controller works fine.
-
Open a terminal on your computer if you don’t have one open already.
-
Connect the terminal environment to the
node1
you created.a. Use the
docker-machine env
command to get the settings.$ docker-machine env node1 export DOCKER_TLS_VERIFY="1" export DOCKER_HOST="tcp://<IP_ADDRESS>:2376" export DOCKER_CERT_PATH="/Users/ldr/.docker/machine/machines/node1" export DOCKER_MACHINE_NAME="node1" # Run this command to configure your shell: # eval $(docker-machine env node1)
b. Run the
eval
command found in the final line to set your environment.$ eval $(docker-machine env node1)
Running this
eval
command sends thedocker
commands in the following steps to the Docker Engine onnode1
.c. Verify that
node1
is the active environment.You can do this by running
docker-machine ls
and checking that there is an*
(asterisk) in theACTIVE
field next tonode1
.  Instead, edit the command supplied to replace it with the actual IP address.The first time you run the
ucp
tool, thedocker run
command pulls the UCP bootstrapper image from Docker Hub. The tool downloads the packages it needs, and verifies that your system will support a UCP installation. -
Enter a password for UCP when prompted, and then confirm it.
The system prompts you for Subject alternative names (SANs). In this sandbox, you’ve already provided the IP address and the
ucp
tool discovered this for you and shows it in the controller list. -
Press enter to proceed using the list the
ucp
tool provided.UCP requires that all clients, including the Docker Engine, use a Swarm TLS certificate chain signed by the UCP Swarm Root CA. You can provide the certificate system with subject alternative names or SANs, which allow you to set up individual “leaf certificates.”
When it completes, the
ucp
tool prompts you to log in into the UCP web interface and gives you its location. You do this in the next step so you can install a license.
Step 3. License your installation
In this step, you get a license, log in to the UCP web interface and install the license. Docker allows you to run an evaluation version of UCP with a single controller and node for up to 30 days.
Learn how to get a trial license.
In your terminal window you should have instructions on how to access the UCP web UI. It should look like this:
INFO[0056] Login as "admin"/(your admin password) to UCP at https://<IP_ADDRESS>:443
In your browser navigate to that IP address, and upload your trial license.
Step 4. Join a node
In this step, you join your node2
to the controller using the ucp join
command. In a production installation, you’d do this step for each node
you want to add.
-
Open a terminal on your computer if you don’t already have one open.
-
Connect the terminal environment to the
node2
you provisioned earlier.- Use
docker-machine env
command to get the settings command fornode2
.
$ docker-machine env node2 export DOCKER_TLS_VERIFY="1" export DOCKER_HOST="tcp://<IP_ADDRESS>:2376" export DOCKER_CERT_PATH="/Users/ldr/.docker/machine/machines/node2" export DOCKER_MACHINE_NAME="node2" # Run this command to configure your shell: # eval $(docker-machine env node2)
b. Run the
eval
command to set your environment.$ eval $(docker-machine env node2)
Running this
eval
command sends thedocker
commands in the following steps to the Docker Engine onnode2
. - Use
-
Run the
docker/ucp join
command.Note: If you are on a Windows system, your shell can’t resolve the
$(docker-machine ip node2)
variable. Instead, edit the command supplied to replace it with the actual IP address.$ docker run --rm -it \ -v /var/run/docker.sock:/var/run/docker.sock \ --name ucp docker/ucp join -i \ --host-address $(docker-machine ip node2)
The
join
command pulls several images, then prompts you for the URL of the UCP Server. -
Enter the URL of the UCP server to continue.
-
Press
y
when prompted to continue and join the node to the swarm. -
Enter the admin username and password for the UCP server when prompted.
The installer continues and prompts you for SANs. In this sandbox, you’ve already provided the IP address and the
ucp
tool discovered this for you and shows it in the controller list. -
Press
enter
to proceed without providing a SAN.The installation is complete when you see the message
Starting local swarm containers
. -
Log in to UCP with your browser and confirm that the new node appears.
Step 5: Install Docker Trusted Registry
Next, we install Docker Trusted Registry (DTR). DTR provides a secure location to store your organization’s Docker images. Images are used by UCP to run containers that make up a service. By providing a secure connection between DTR and UCP, you can verify that your production services contain only signed code produced by your own organization.
-
First, make sure you know the IP addresses of both your UCP and DTR nodes. You can find this easily by running
docker-machine ls
. -
Run the
docker-machine env node2
command to make sure that you are passing commands to the node on which you will install DTR. -
Next, use the following command to install DTR on
node2
.$ docker run -it --rm docker/dtr install \ --ucp-url $(docker-machine ip node1) \ --ucp-insecure-tls \ --ucp-node node2 \ --dtr-external-url $(docker-machine ip node2)
You are prompted for the credentials of the UCP administrator.
-
Verify that DTR is running by navigating your browser to the DTR server’s IP.
-
Confirm that you can log in using your UCP administrator credentials.
Congratulations! You now have a working installation of Docker Datacenter running in your sandbox. You can explore on your own, or continue your evaluation by walking through our guided tour.
