I chose this ecosystem because it's very natural and seems very obvious to prototype. I wanted to be able to build a natural ecosystem that users can watch peacefully and let it grow. In order to have an apple tree grow in an environment, I thought of 3 essential objects that affect the tree: sun, sky, and cloud.  As shown in a diagram below.
In order to have an essential environment for a tree, it would also need environmental changes where it would rain on certain occasions and have it's own time so that sun can rise and set.
I originally thought to have naturally growing environment for a tree to grow, but there was no interaction. There needed to be ways for users to be more engaged with the prototype.
In the code, itw as difficult to find right timing for the enviornment to start raining and how to keep track of the environment so that the tree would grow depending on how much sunlight and water it receives.
void updateTime() {
if (rate >= 1) {
rate = 0;
minutes += 1;
} else {
rate++;
}
if (minutes == 60) {
minutes = 0;
hours++;
}
if (hours == 24) {
hours = 0;
day++;
}
}
Since 30 frames are drawn in a second, I created own updateTime function to update the time every frame. Therefore, every second, the prototype's in-time would be 30 minutes.
Since it would be unrealistic for users to be able to change time, it was more natural for users to create clouds if the users want it to rain, so that the user can simply click on the screen and probability of raining will increase as numbers of clouds adds up on the screen.
While clouds are able to be generated from clicking the screen, it's also generated randomly every 1/30 of the seconds. It's not implemented yet, but the goal is that the user will have enough balance of precipitation so that the tree won't die.
The spaceship can move around, rotate and shoot missles. Once an asteroid collides with the ship, the game is over.
Right now, it will rain when there are 20 clouds shown on the screen. However, that means that the users can keep clicking on the screen whenever they want it to rain. It would be more interesting to have the chance of rain to increase as the number of clouds increase.
Sun rises and sets, and it's only hidden when it rains. Right now, the user has to make the environment rain so that the tree will grow. However, users will be more engaged in making the rain happen with probabilities, and having them to realize that having too much of water will eventually kill the tree. If this is implemented, the users have to make decisions on when create clouds.

The EC2 discovery plugin provides a list of seed addresses to the discovery process by querying the AWS API for a list of EC2 instances matching certain criteria determined by the plugin settings.
Installation
This plugin can be installed using the plugin manager:
sudo bin/opensearch-plugin install discovery-ec2
The plugin must be installed on every node in the cluster, and each node must be restarted after installation.
You can download this plugin for offline
install from https://artifacts.opensearch.org/downloads/opensearch-plugins/discovery-ec2/discovery-ec2-1.0.0.zip. To verify
the .zip
file, use the
SHA hash or
ASC key.
Removal
The plugin can be removed with the following command:
sudo bin/opensearch-plugin remove discovery-ec2
The node must be stopped before removing the plugin.
Using the EC2 discovery plugin
The discovery-ec2
plugin allows OpenSearch to find the master-eligible nodes in a
cluster running on AWS EC2 by querying the
AWS API for the addresses of the EC2
instances running these nodes.
It is normally a good idea to restrict the discovery process just to the master-eligible nodes in the cluster. This plugin allows you to identify these nodes by certain criteria including their tags, their membership of security groups, and their placement within availability zones. The discovery process will work correctly even if it finds master-ineligible nodes, but master elections will be more efficient if this can be avoided.
The interaction with the AWS API can be authenticated using the instance role, or else custom credentials can be supplied.
Enabling EC2 discovery
To enable EC2 discovery, configure OpenSearch to use the ec2
seed hosts provider:
discovery.seed_providers: ec2
Configuring EC2 discovery
EC2 discovery supports a number of settings. Some settings are sensitive and must be stored in the OpenSearch keystore. For example, to authenticate using a particular access key and secret key, add these keys to the keystore by running the following commands:
bin/opensearch-keystore add discovery.ec2.access_key
bin/opensearch-keystore add discovery.ec2.secret_key
The available settings for the EC2 discovery plugin are as follows.
discovery.ec2.access_key
(Secure, reloadable)-
An EC2 access key. If set, you must also set
discovery.ec2.secret_key
. If unset,discovery-ec2
will instead use the instance role. This setting is sensitive and must be stored in the OpenSearch keystore. discovery.ec2.secret_key
(Secure, reloadable)-
An EC2 secret key. If set, you must also set
discovery.ec2.access_key
. This setting is sensitive and must be stored in the OpenSearch keystore. discovery.ec2.session_token
(Secure, reloadable)-
An EC2 session token. If set, you must also set
discovery.ec2.access_key
anddiscovery.ec2.secret_key
. This setting is sensitive and must be stored in the OpenSearch keystore. discovery.ec2.endpoint
-
The EC2 service endpoint to which to connect. See https://docs.aws.amazon.com/general/latest/gr/rande.html#ec2_region to find the appropriate endpoint for the region. This setting defaults to
ec2.us-east-1.amazonaws.com
which is appropriate for clusters running in theus-east-1
region. discovery.ec2.protocol
-
The protocol to use to connect to the EC2 service endpoint, which may be either
http
orhttps
. Defaults tohttps
. discovery.ec2.proxy.host
-
The address or host name of an HTTP proxy through which to connect to EC2. If not set, no proxy is used.
discovery.ec2.proxy.port
-
When the address of an HTTP proxy is given in
discovery.ec2.proxy.host
, this setting determines the port to use to connect to the proxy. Defaults to80
. discovery.ec2.proxy.username
(Secure, reloadable)-
When the address of an HTTP proxy is given in
discovery.ec2.proxy.host
, this setting determines the username to use to connect to the proxy. When not set, no username is used. This setting is sensitive and must be stored in the OpenSearch keystore. discovery.ec2.proxy.password
(Secure, reloadable)-
When the address of an HTTP proxy is given in
discovery.ec2.proxy.host
, this setting determines the password to use to connect to the proxy. When not set, no password is used. This setting is sensitive and must be stored in the OpenSearch keystore. discovery.ec2.read_timeout
-
The socket timeout for connections to EC2, including the units. For example, a value of
60s
specifies a 60-second timeout. Defaults to 50 seconds. discovery.ec2.groups
-
A list of the names or IDs of the security groups to use for discovery. The
discovery.ec2.any_group
setting determines the behaviour of this setting. Defaults to an empty list, meaning that security group membership is ignored by EC2 discovery. discovery.ec2.any_group
-
Defaults to
true
, meaning that instances belonging to any of the security groups specified indiscovery.ec2.groups
will be used for discovery. If set tofalse
, only instances that belong to all of the security groups specified indiscovery.ec2.groups
will be used for discovery. discovery.ec2.host_type
-
Each EC2 instance has a number of different addresses that might be suitable for discovery. This setting allows you to select which of these addresses is used by the discovery process. It can be set to one of
private_ip
,public_ip
,private_dns
,public_dns
ortag:TAGNAME
whereTAGNAME
refers to a name of a tag. This setting defaults toprivate_ip
.If you set
discovery.ec2.host_type
to a value of the formtag:TAGNAME
then the value of the tagTAGNAME
attached to each instance will be used as that instance’s address for discovery. Instances which do not have this tag set will be ignored by the discovery process.For example if you tag some EC2 instances with a tag named
opensearch-host-name
and sethost_type: tag:opensearch-host-name
then thediscovery-ec2
plugin will read each instance’s host name from the value of theopensearch-host-name
tag. Read more about EC2 Tags. discovery.ec2.availability_zones
-
A list of the names of the availability zones to use for discovery. The name of an availability zone is the region code followed by a letter, such as
us-east-1a
. Only instances placed in one of the given availability zones will be used for discovery.
discovery.ec2.tag.TAGNAME
-
A list of the values of a tag called
TAGNAME
to use for discovery. If set, only instances that are tagged with one of the given values will be used for discovery. For instance, the following settings will only use nodes with arole
tag set tomaster
and anenvironment
tag set to eitherdev
orstaging
.discovery.ec2.tag.role: master discovery.ec2.tag.environment: dev,staging
NoteThe names of tags used for discovery may only contain ASCII letters, numbers, hyphens and underscores. In particular you cannot use tags whose name includes a colon. discovery.ec2.node_cache_time
-
Sets the length of time for which the collection of discovered instances is cached. OpenSearch waits at least this long between requests for discovery information from the EC2 API. AWS may reject discovery requests if they are made too often, and this would cause discovery to fail. Defaults to
10s
.
All secure settings of this plugin are reloadable, allowing you to update the secure settings for this plugin without needing to restart each node.
Recommended EC2 permissions
The discovery-ec2
plugin works by making a DescribeInstances
call to the AWS
EC2 API. You must configure your AWS account to allow this, which is normally
done using an IAM policy. You can create a custom policy via the IAM Management
Console. It should look similar to this.
{
"Statement": [
{
"Action": [
"ec2:DescribeInstances"
],
"Effect": "Allow",
"Resource": [
"*"
]
}
],
"Version": "2012-10-17"
}
Automatic node attributes
The discovery-ec2
plugin can automatically set the aws_availability_zone
node attribute to the availability zone of each node. This node attribute
allows you to ensure that each shard has copies allocated redundantly across
multiple availability zones by using the
Allocation Awareness
feature.
In order to enable the automatic definition of the aws_availability_zone
attribute, set cloud.node.auto_attributes
to true
. For example:
cloud.node.auto_attributes: true
cluster.routing.allocation.awareness.attributes: aws_availability_zone
The aws_availability_zone
attribute can be automatically set like this when
using any discovery type. It is not necessary to set discovery.seed_providers:
ec2
. However this feature does require that the discovery-ec2
plugin is
installed.
Binding to the correct address
It is important to define network.host
correctly when deploying a cluster on
EC2. By default each OpenSearch node only binds to localhost
, which will prevent it
from being discovered by nodes running on any other instances.
You can use the core network host settings to bind
each node to the desired address, or you can set network.host
to one of the
following EC2-specific settings provided by the discovery-ec2
plugin:
| EC2 Host Value | Description |
|---|---|
|
The private IP address (ipv4) of the machine. |
|
The private host of the machine. |
|
The public IP address (ipv4) of the machine. |
|
The public host of the machine. |
|
Equivalent to |
|
Equivalent to |
|
Equivalent to |
These values are acceptable when using any discovery type. They do not require
you to set discovery.seed_providers: ec2
. However they do require that the
discovery-ec2
plugin is installed.
Best Practices in AWS
This section contains some other information about designing and managing an OpenSearch cluster on your own AWS infrastructure.
Storage
EC2 instances offer a number of different kinds of storage:
-
Instance storage works well for OpenSearch clusters and offers excellent performance. Because it replicates each shard across multiple nodes, OpenSearch works well with this kind of ephemeral storage. If a node fails and its instance storage is lost, OpenSearch rebuilds any lost shards from replicas.
-
EBS-based storage also works well, especially on modern instance types. Be sure to use provisioned IOPS to ensure your cluster has satisfactory performance.
-
EFS-based storage is not recommended. Historically, shared network filesystems such as EFS have not always offered precisely the behaviour that OpenSearch requires of its filesystem, which can lead to index corruption. Although EFS offers durability, shared storage, and the ability to grow and shrink filesystems dynamically, you can achieve the same benefits using OpenSearch directly.
Choice of AMI
We recommend the Amazon Linux 2 AMIs. These images are lightweight and have EC2-specific performance enhancements.
Networking
-
Smaller instance types have less network bandwidth. Check the EC2 instance types to make sure the bandwidth meets your needs.
-
It is a good idea to distribute your nodes across multiple availability zones and use shard allocation awareness to ensure that each shard has copies in more than one availability zone.
-
Do not span a cluster across regions. OpenSearch expects that node-to-node connections within a cluster are reasonably reliable and offer high bandwidth and low latency, and these properties do not hold for connections between regions. Although an OpenSearch cluster will behave correctly when node-to-node connections are unreliable or slow, it is not optimised for this case and its performance may suffer. If you wish to geographically distribute your data, use features like cross-cluster search.
Other recommendations
-
If you have split your nodes into roles, consider tagging the EC2 instances by role to make it easier to filter and view your EC2 instances in the AWS console.
-
Consider enabling termination protection for all of your data and master-eligible nodes. This will help to prevent accidental termination of these nodes which could temporarily reduce the resilience of the cluster and which could cause a potentially disruptive reallocation of shards.
-
If running your cluster using one or more auto-scaling groups, consider protecting your data and master-eligible nodes against termination during scale-in. This helps prevent automatic termination of these nodes, which could temporarily reduce the resilience of the cluster and could cause a potentially disruptive reallocation of shards. If these instances are protected against termination during scale-in, you can use shard allocation filtering to gracefully migrate any data off these nodes before terminating them manually.
Azure Classic Discovery Plugin
The deprecated Azure Classic Discovery plugin uses the Azure Classic API to identify the addresses of seed hosts.
Installation
This plugin can be installed using the plugin manager:
sudo bin/opensearch-plugin install discovery-azure-classic
The plugin must be installed on every node in the cluster, and each node must be restarted after installation.
You can download this plugin for offline
install from https://artifacts.opensearch.org/downloads/opensearch-plugins/discovery-azure-classic/discovery-azure-classic-1.0.0.zip. To verify
the .zip
file, use the
SHA hash or
ASC key.
Removal
The plugin can be removed with the following command:
sudo bin/opensearch-plugin remove discovery-azure-classic
The node must be stopped before removing the plugin.
Azure Virtual Machine Discovery
Azure VM discovery allows to use the Azure APIs to perform automatic discovery. Here is a simple sample configuration:
cloud:
azure:
management:
subscription.id: XXX-XXX-XXX-XXX
cloud.service.name: opensearch-demo-app
keystore:
path: /path/to/azurekeystore.pkcs12

Advanced settings
The following are a list of settings that can further control the discovery:
discovery.azure.host.type
-
Either
public_ip
orprivate_ip
(default). Azure discovery will use the one you set to ping other nodes. discovery.azure.endpoint.name
-
When using
public_ip
this setting is used to identify the endpoint name used to forward requests to OpenSearch (aka transport port name). Defaults toopensearch
. In Azure management console, you could define an endpointopensearch
forwarding for example requests on public IP on port 8100 to the virtual machine on port 9300. discovery.azure.deployment.name
-
Deployment name if any. Defaults to the value set with
cloud.azure.management.cloud.service.name
. discovery.azure.deployment.slot
-
Either
staging
orproduction
(default).
For example:
discovery:
type: azure
azure:
host:
type: private_ip
endpoint:
name: opensearch
deployment:
name: your_azure_cloud_service_name
slot: production
Setup process for Azure Discovery
We will expose here one strategy which is to hide our OpenSearch cluster from outside.
With this strategy, only VMs behind the same virtual port can talk to each other. That means that with this mode, you can use OpenSearch unicast discovery to build a cluster, using the Azure API to retrieve information about your nodes.
Prerequisites
Before starting, you need to have:
-
OpenSSL that isn’t from MacPorts, specifically
OpenSSL 1.0.1f 6 Jan 2014
doesn’t seem to create a valid keypair for ssh. FWIW,OpenSSL 1.0.1c 10 May 2012
on Ubuntu 14.04 LTS is known to work. -
SSH keys and certificate
You should follow this guide to learn how to create or use existing SSH keys. If you have already did it, you can skip the following.
Here is a description on how to generate SSH keys using
openssl
:# You may want to use another dir than /tmp cd /tmp openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout azure-private.key -out azure-certificate.pem chmod 600 azure-private.key azure-certificate.pem openssl x509 -outform der -in azure-certificate.pem -out azure-certificate.cer
Generate a keystore which will be used by the plugin to authenticate with a certificate all Azure API calls.
# Generate a keystore (azurekeystore.pkcs12) # Transform private key to PEM format openssl pkcs8 -topk8 -nocrypt -in azure-private.key -inform PEM -out azure-pk.pem -outform PEM # Transform certificate to PEM format openssl x509 -inform der -in azure-certificate.cer -out azure-cert.pem cat azure-cert.pem azure-pk.pem > azure.pem.txt # You MUST enter a password! openssl pkcs12 -export -in azure.pem.txt -out azurekeystore.pkcs12 -name azure -noiter -nomaciter
Upload the
azure-certificate.cer
file both in the OpenSearch Cloud Service (underManage Certificates
), and underSettings → Manage Certificates
.ImportantWhen prompted for a password, you need to enter a non empty one. See this guide for more details about how to create keys for Azure.
Once done, you need to upload your certificate in Azure:
-
Go to the management console.
-
Sign in using your account.
-
Click on
Portal
. -
Go to Settings (bottom of the left list)
-
On the bottom bar, click on
Upload
and upload yourazure-certificate.cer
file.
You may want to use Windows Azure Command-Line Tool:
-
-
Install NodeJS, for example using homebrew on MacOS X:
brew install node
-
Install Azure tools
sudo npm install azure-cli -g
-
Download and import your azure settings:
# This will open a browser and will download a .publishsettings file azure account download # Import this file (we have downloaded it to /tmp) # Note, it will create needed files in ~/.azure. You can remove azure.publishsettings when done. azure account import /tmp/azure.publishsettings
Creating your first instance
You need to have a storage account available. Check Azure Blob Storage documentation for more information.
You will need to choose the operating system you want to run on. To get a list of official available images, run:
azure vm image list
Let’s say we are going to deploy an Ubuntu image on an extra small instance in West Europe:
| Azure cluster name |
|
| Image |
|
| VM Name |
|
| VM Size |
|
| Location |
|
| Login |
|
| Password |
|
Using command line:
azure vm create azure-opensearch-cluster \
b39f27a8b8c64d52b05eac6a62ebad85__Ubuntu-13_10-amd64-server-20130808-alpha3-en-us-30GB \
--vm-name myesnode1 \
--location "West Europe" \
--vm-size extrasmall \
--ssh 22 \
--ssh-cert /tmp/azure-certificate.pem \
opensearch password1234\!\!
You should see something like:
info: Executing command vm create
+ Looking up image
+ Looking up cloud service
+ Creating cloud service
+ Retrieving storage accounts
+ Configuring certificate
+ Creating VM
info: vm create command OK
Now, your first instance is started.

Tip
|
Working with SSH
You need to give the private key and username each time you log on your instance:
But you can also define it once in
|
Next, you need to install OpenSearch on your new instance. First, copy your keystore to the instance, then connect to the instance using SSH:
scp /tmp/azurekeystore.pkcs12 azure-opensearch-cluster.cloudapp.net:/home/opensearch
ssh azure-opensearch-cluster.cloudapp.net
Once connected, install OpenSearch and check that it is running:
GET /
This command should give you a JSON result:
{
"name" : "Cp8oag6",
"cluster_name" : "opensearch",
"cluster_uuid" : "AT69_T_DTp-1qgIJlatQqA",
"version" : {
"number" : "{bare_version}",
"build_type" : "tar",
"build_hash" : "f27399d",
"build_date" : "2016-03-30T09:51:41.449Z",
"build_snapshot" : false,
"lucene_version" : "8.7.0",
"minimum_wire_compatibility_version" : "1.2.3",
"minimum_index_compatibility_version" : "1.2.3"
}
}
Install OpenSearch cloud azure plugin
# Stop OpenSearch
sudo service opensearch stop
# Install the plugin
sudo /usr/share/opensearch/bin/opensearch-plugin install discovery-azure-classic
# Configure it
sudo vi /etc/opensearch/opensearch.yml
And add the following lines:
# If you don't remember your account id, you may get it with `azure account list`
cloud:

password: your_password_for_keystore
discovery:
type: azure
# Recommended (warning: non durable disk)
# path.data: /mnt/resource/opensearch/data
Restart OpenSearch:
sudo service opensearch start
If anything goes wrong, check your logs in /var/log/opensearch
.
Scaling Out!
You need first to create an image of your previous machine. Disconnect from your machine and run locally the following commands:
# Shutdown the instance
azure vm shutdown myesnode1
# Create an image from this instance (it could take some minutes)
azure vm capture myesnode1 esnode-image --delete
# Note that the previous instance has been deleted (mandatory)
# So you need to create it again and BTW create other instances.
azure vm create azure-opensearch-cluster \
esnode-image \
--vm-name myesnode1 \
--location "West Europe" \
--vm-size extrasmall \
--ssh 22 \
--ssh-cert /tmp/azure-certificate.pem \
opensearch password1234\!\!

Tip
|
It could happen that azure changes the endpoint public IP address. DNS propagation could take some minutes before you can connect again using name. You can get from azure the IP address if needed, using:
|
Let’s start more instances!
for x in $(seq 2 10)
do
echo "Launching azure instance #$x..."

Installation
This plugin can be installed using the plugin manager:

GCE Virtual Machine Discovery
Google Compute Engine VM discovery allows to use the google APIs to perform automatic discovery of seed hosts. Here is a simple sample configuration:
cloud:
gce:
project_id: <your-google-project-id>
zone: <your-zone>
discovery:
seed_providers: gce
The following gce settings (prefixed with cloud.gce
) are supported:
project_id
-
Your Google project id. By default the project id will be derived from the instance metadata.
Note: Deriving the project id from system properties or environment variables (`GOOGLE_CLOUD_PROJECT` or `GCLOUD_PROJECT`) is not supported.
zone
-
helps to retrieve instances running in a given zone. It should be one of the GCE supported zones. By default the zone will be derived from the instance metadata. See also Using GCE zones.
retry
-
If set to
true
, client will use ExponentialBackOff policy to retry the failed http request. Defaults totrue
. max_wait
-
The maximum elapsed time after the client instantiating retry. If the time elapsed goes past the
max_wait
, client stops to retry. A negative value means that it will wait indefinitely. Defaults to0s
(retry indefinitely). refresh_interval
-
How long the list of hosts is cached to prevent further requests to the GCE API.
0s
disables caching. A negative value will cause infinite caching. Defaults to0s
.

Binding the network host
It’s important to define You can use core network host settings or gce specific host settings: |
GCE Network Host
When the discovery-gce
plugin is installed, the following are also allowed
as valid network host settings:
| GCE Host Value | Description |

Setting up GCE Discovery
Prerequisites
Before starting, you need:
-
Your project ID, e.g.
opensearch-cloud
. Get it from Google API Console. -
To install Google Cloud SDK
If you did not set it yet, you can define your default project you will work on:
gcloud config set project opensearch-cloud
Login to Google Cloud
If you haven’t already, login to Google Cloud
gcloud auth login
This will open your browser. You will be asked to sign-in to a Google account and authorize access to the Google Cloud SDK.
Creating your first instance
gcloud compute instances create myopensearchnode1 \
--zone <your-zone> \
--scopes compute-rw
When done, a report like this one should appears:
Created [https://www.googleapis.com/compute/v1/projects/opensearch-cloud-1070/zones/us-central1-f/instances/myesnode1].
NAME ZONE MACHINE_TYPE PREEMPTIBLE INTERNAL_IP EXTERNAL_IP STATUS
myopensearchnode1 us-central1-f n1-standard-1 <IP_ADDRESS> <IP_ADDRESS> RUNNING
You can now connect to your instance:
# Connect using google cloud SDK
gcloud compute ssh myopensearchnode1 --zone europe-west1-a
# Or using SSH with external IP address
ssh -i ~/.ssh/google_compute_engine <IP_ADDRESS>
|
Important
|
Service Account Permissions
It’s important when creating an instance that the correct permissions are set. At a minimum, you must ensure you have:
Failing to set this will result in unauthorized messages when starting OpenSearch. See Machine Permissions. |
Once connected, install OpenSearch:
Install OpenSearch discovery gce plugin
Install the plugin:
# Use Plugin Manager to install it
sudo bin/opensearch-plugin install discovery-gce
Open the opensearch.yml
file:
sudo vi /etc/opensearch/opensearch.yml
And add the following lines:
cloud:
gce:
project_id: opensearch-cloud
zone: europe-west1-a
discovery:
seed_providers: gce
Start OpenSearch:
sudo /etc/init.d/opensearch start
If anything goes wrong, you should check logs:
tail -f /var/log/opensearch/opensearch.log
If needed, you can change log level to trace
by opening log4j2.properties
:
sudo vi /etc/opensearch/log4j2.properties
and adding the following line:
# discovery
logger.discovery_gce.name = discovery.gce
logger.discovery_gce.level = trace
Cloning your existing machine
In order to build a cluster on many nodes, you can clone your configured instance to new nodes. You won’t have to reinstall everything!
First create an image of your running instance and upload it to Google Cloud Storage:
# Create an image of your current instance
sudo /usr/bin/gcimagebundle -d /dev/sda -o /tmp/
# An image has been created in `/tmp` directory:
ls /tmp
e4686d7f5bf904a924ae0cfeb58d0827c6d5b966.image.tar.gz
# Upload your image to Google Cloud Storage:
# Create a bucket to hold your image, let's say `opensearchimage`:
gsutil mb gs://opensearchimage
# Copy your image to this bucket:
gsutil cp /tmp/e4686d7f5bf904a924ae0cfeb58d0827c6d5b966.image.tar.gz gs://opensearchimage
# Then add your image to images collection:
gcloud compute images create opensearch-2-0-0 --source-uri gs://opensearchimage/e4686d7f5bf904a924ae0cfeb58d0827c6d5b966.image.tar.gz
# If the previous command did not work for you, logout from your instance
# and launch the same command from your local machine.
Start new instances
As you have now an image, you can create as many instances as you need:
# Just change node name (here myopensearchnode2)
gcloud compute instances create myopensearchnode2 --image opensearch-2-0-0 --zone europe-west1-a
# If you want to provide all details directly, you can use:
gcloud compute instances create myopensearchnode2 --image=opensearch-2-0-0 \
--zone europe-west1-a --machine-type f1-micro --scopes=compute-rw
Remove an instance (aka shut it down)
You can use Google Cloud Console or CLI to manage your instances:
# Stopping and removing instances
gcloud compute instances delete myopensearchnode1 myopensearchnode2 \
--zone=europe-west1-a
# Consider removing disk as well if you don't need them anymore
gcloud compute disks delete boot-myopensearchnode1 boot-myopensearchnode2 \
--zone=europe-west1-a
Using GCE zones
cloud.gce.zone
helps to retrieve instances running in a given zone. It should be one of the
GCE supported zones.
The GCE discovery can support multi zones although you need to be aware of network latency between zones.
To enable discovery across more than one zone, just enter add your zone list to cloud.gce.zone
setting:
cloud:
gce:
project_id: <your-google-project-id>
zone: ["<your-zone1>", "<your-zone2>"]
discovery:
seed_providers: gce
Filtering by tags
The GCE discovery can also filter machines to include in the cluster based on tags using discovery.gce.tags
settings.
For example, setting discovery.gce.tags
to dev
will only filter instances having a tag set to dev
. Several tags
set will require all of those tags to be set for the instance to be included.
One practical use for tag filtering is when a GCE cluster contains many nodes that are not master-eligible OpenSearch nodes. In this case, tagging the GCE instances that are running the master-eligible OpenSearch nodes, and then filtering by that tag, will help discovery to run more efficiently.
Add your tag when building the new instance:
gcloud compute instances create myopensearchnode1 --project=opensearch-cloud \
--scopes=compute-rw \
--tags=opensearch,dev
Then, define it in opensearch.yml
:
cloud:
gce:
project_id: opensearch-cloud
zone: europe-west1-a
discovery:
seed_providers: gce
gce:
tags: opensearch, dev
Changing default transport port
By default, OpenSearch GCE plugin assumes that you run OpenSearch on 9300 default port.
But you can specify the port value OpenSearch is meant to use using google compute engine metadata opensearch_port
:
When creating instance
Add --metadata opensearch_port=9301
option:
# when creating first instance
gcloud compute instances create myopensearchnode1 \
--scopes=compute-rw,storage-full \
--metadata opensearch_port=9301
# when creating an instance from an image
gcloud compute instances create myopensearchnode2 --image=opensearch-1-0-0-RC1 \
--zone europe-west1-a --machine-type f1-micro --scopes=compute-rw \
--metadata opensearch_port=9301
On a running instance
gcloud compute instances add-metadata myopensearchnode1 \
--zone europe-west1-a \
--metadata opensearch_port=9301
GCE Tips
Store project id locally
If you don’t want to repeat the project id each time, you can save it in the local gcloud config
gcloud config set project opensearch-cloud
Machine Permissions
If you have created a machine without the correct permissions, you will see 403 unauthorized
error messages. To change machine permission on an existing instance, first stop the instance then Edit. Scroll down to Access Scopes
to change permission. The other way to alter these permissions is to delete the instance (NOT THE DISK). Then create another with the correct permissions.
- Creating machines with gcloud
-
Ensure the following flags are set:
--scopes=compute-rw
- Creating with console (web)
-
When creating an instance using the web portal, click Show advanced options.
At the bottom of the page, under
PROJECT ACCESS
, choose>> Compute >> Read Write
. - Creating with knife google
-
Set the service account scopes when creating the machine:
knife google server create www1 \ -m n1-standard-1 \ -I debian-8 \ -Z us-central1-a \ -i ~/.ssh/id_rsa \ -x jdoe \ --gce-service-account-scopes https://www.googleapis.com/auth/compute.full_control
Or, you may use the alias:
--gce-service-account-scopes compute-rw
Testing GCE
Integrations tests in this plugin require working GCE configuration and therefore disabled by default. To enable tests prepare a config file opensearch.yml with the following content:
cloud:
gce:
project_id: opensearch-cloud
zone: europe-west1-a
discovery:
seed_providers: gce
Replaces project_id
and zone
with your settings.
To run test:
mvn -Dtests.gce=true -Dtests.config=/path/to/config/file/opensearch.yml clean test

We purchased our ThermoSecure Thermostat to help save on heating and cooling costs. In the first month we had it we saw a big difference in the amount of heat we paid for. I love the look, it was easy to install, easy to use and I really like having the app on my phone and the ability to control our HomeCone from anywhere. I would highly recommend this product its amazing.
Trevor V. | January 18, 2018
This is absolutely the best thermostat available! Beautiful design. Quick and simple installation. Plenty of help online if you don’t think it’s so easy, or you can get a professional installer. Smart AI. Great features / functions (learning your preferences, when you’re home or away, turning on or off to minimize overshooting temperature goals, scheduling). Adjustable from the unit, mobile app, or the web. Remote interfaces are easy to use, and show a 10-day history.
Jarrod O. | March, 2018
The HouseCon thermostat has helped save me money and made adjusting the temperature of the house easier. I can turn the heat up before I get home to warm things up after being away so I don’t come home to a cold house. The auto-away function saves me money by not running the furnace when I’m away but keeping my house from getting to cold. Easy to install, setup and operate! Works great both with my Amazon Alexa and my Google Home devices!
When products work with ThermoSecure, you don’t have to tell them how to connect. Or what to do. They just work. In real homes for real people.

Susan Granger's review of "THE PATRIOT" (Columbia Pictures)
Do you realize there's never been a big, blockbuster Revolutionary War movie - until now? "The Patriot" will change all that. In 1776 in South Carolina, Benjamin Martin (Mel Gibson), a former hero of the French and Indian War, is now a widower and devoted father of seven children. Rebuking those who advocate war against England's King George III over taxation, he's become a pacifist - until the battle literally lands in his backyard, as a cruel, arrogant British colonel (Jason Isaacs) deliberately murders an innocent child.  These excellent marksmen are guerrilla fighters, avoiding muzzle-to-muzzle confrontations with Redcoats in an open field. But Martin's not the real patriot - that honor goes to his idealistic son Gabriel (Heath Ledger), whose early enlistment in the Colonial Army is motivated by principle. Written by Robert Rodat ("Saving Private Ryan") and directed by Roland Emmerich ("Independence Day"), it's a challenging, exciting, character-driven story, capturing the human element that is too often lost in history - with heart-wrenching moments like melting a lead toy soldier into ammunition. As the tale's emotional pivot, the conflicted father and reluctant hero, Mel Gibson delivers a touching, tautly textured performance, ably supported by Heath Ledger, Jason Isaacs, Chris Cooper, Tcheky Karyo, Rene Aubjonois, Lisa Brenner and Tom Wilkinson. Caleb Deschanel's cinematography is magnificent, even when capturing the violence of war at its most brutal, and John Williams's score is superb. Sure, there are some cliches, but on the Granger Movie Gauge of 1 to 10, "The Patriot" is a compelling, powerful 10. It's a stunning, sweeping, spectacular saga.

WEEK 4 MONDAY
Year 1 (Year 2)
FIRST READING Hebrews 11:32-40
A reading from the Letter to the Hebrews
Brethren: What more
shall I say? For time would fail me to tell of Gideon, Barak,
Samson, Jephthah, of David and Samuel and the
prophets-- who through faith conquered kingdoms, enforced justice, received
promises, stopped the mouths of lions, quenched raging fire, escaped the edge
of the sword, won strength out of weakness, became mighty in war, put foreign
armies to flight. Women received their dead by resurrection. Some were
tortured, refusing to accept release, that they might
rise again to a better life. Others suffered mocking and scourging, and even
chains and imprisonment. They were stoned, they were sawn in two, they were
killed with the sword; they went about in skins of sheep and goats, destitute,
afflicted, ill-treated-- of whom the world was not
worthy-- wandering over deserts and mountains, and in dens and caves of the
earth. And all these, though well attested by their faith, did not receive what
was promised, since God had foreseen something better for us, that apart from
us they should not be made perfect.
The word of the Lord
RESPONSORIAL PSALM Psalm 31:<IP_ADDRESS>.24 (R. 25)
R. Be strong, let your heart take courage, all who hope in the Lord.
How great is the
goodness, LORD, that you keep for those who fear you, that
you show to those who trust you in the sight of the children of men.
R. Be strong, let your
heart take courage, all who hope in the Lord.
You hide them in the
shelter of your presence, secure from human scheming; you keep them safe within
your tent from disputing tongues.
R. Be strong, let your
heart take courage, all who hope in the Lord.
Blest be the LORD
for he has wondrously shown me his merciful love in a fortified city!
R. Be strong, let your
heart take courage, all who hope in the Lord.
'I am far removed
from your sight,' I said in my alarm. Yet you heard the voice of my plea when I
cried to you for help.
R. Be strong, let your
heart take courage, all who hope in the Lord.
Love the LORD, all
you his saints. The LORD guards the faithful. But the LORD will repay to the
full the one who acts with pride.
R. Be strong, let your
heart take courage, all who hope in the Lord.
FIRST READING 2 Samuel 15:13-14.30; 16:5-13

The word of the Lord
RESPONSORIAL PSALM Psalm 3:2-3.4-5.6-7 (R. 7c))
R. Arise, Lord, save me.
How many are my foes, O LORD! How many are rising
up against me! How many are saying about me, 'There is no help for him in God.'
R. Arise, Lord, save me.
 I cry aloud to the LORD. From his holy mountain he answers me.
R. Arise, Lord, save me.
I lie down, I sleep and I wake, for the LORD
upholds me. I will not fear even thousands of people who are ranged on every
side against me. Arise, LORD; save me, my God.
R. Arise, Lord, save me.
R. Alleluia. A great prophet has risen among us, and God has visited his people. R. Alleluia.
GOSPEL Mark 5:1-20
A reading from the holy Gospel according to Mark
At that time: Jesus and his disciples came to the
other side of the sea, to the country of the Gerasenes.
And when he had come out of the boat, there met him out of the tombs a man with
an unclean spirit, who lived among the tombs; and no one could bind him any more,
even with a chain; for he had often been bound with fetters and chains, but the
chains he wrenched apart, and the fetters he broke in pieces; and no one had
the strength to subdue him. Night and day among the tombs and on the mountains
he was always crying out, and bruising himself with stones. And when he saw
Jesus from afar, he ran and worshiped him; and crying out with a loud voice, he
said, "What have you to do with me, Jesus, Son of the Most High God? I
adjure you by God, do not torment me." For he had said to him, "Come
out of the man, you unclean spirit!" And Jesus asked him, "What is
your name?" He replied, "My name is Legion; for we are many." And
he begged him eagerly not to send them out of the country. Now a great herd of
swine was feeding there on the hillside; and they begged him, "Send us to
the swine, let us enter them." So he gave them
leave. And the unclean spirits came out, and entered the swine; and the herd,
numbering about two thousand, rushed down the steep bank into the sea, and were
drowned in the sea. The herdsmen fled, and told it in the city and in the
country. And people came to see what it was that had happened. And they came to
Jesus, and saw the demoniac sitting there, clothed and in his right mind, the
man who had had the legion; and they were afraid. And those who had seen it
told what had happened to the demoniac and to the swine. And they began to beg
Jesus to depart from their neighbourhood. And as he was getting into the boat,
the man who had been possessed with demons begged him that he might be with
him. But he refused, and said to him, "Go home to your friends, and tell
them how much the Lord has done for you, and how he has had mercy on you."
And he went away and began to proclaim in the

Vagrant
In order to allow you to easily set up the required configuration for wallabag, we offer you a Vagrantfile file to be used with Vagrant.
Vagrant is computer software for creating and configuring virtual development environments. It can be seen as a wrapper around virtualization software such as VirtualBox, KVM, VMware and around configuration management software such as Ansible, Chef, Salt or Puppet.
Use Vagrant for wallabag
Here is the procedure to run wallabag inside a Vagrant container:
wget -O wallabag-dev.zip https://github.com/wallabag/wallabag/archive/dev.zip
unzip wallabag-dev.zip
cd wallabag-dev
vagrant up
Now, go to http://localhost:8003
, wallabag should be available there! (make sure you do not use the port 8003 of your machine for something else before)
What did the Vagrantfile install ?
The script install a LAMP server, i.e. :
- Ubuntu 14.04
- an Apache2 web server
- PHP5
- SQLite or MySQL or PostgreSQL for PHP
- XDebug for PHP


Just a couple of days ago, the term “version control” meant nothing more than its most basic definition - controlling or keeping track of different versions of a document, git was just a quicker way of saying GitHub, and GitHub was a website full of terms I didn’t understand that my coding friends would name-drop when geeking out. After a full day of research and command line coding challenges, I’ve begun to understand the importance of version control in the coding world.
We’ve all found ourselves working on a team project at some point in our lives. I can remember the difficulty I faced trying to coordinate edits to a group research paper through email, constantly sharing documents back and forth. Now imagine if you were a web developer, working on a team and writing code to build a website. The chances of overwriting someone else’s changes or working from the wrong version are pretty darn high.
This is where git comes in. Git is a version control software that can be installed on your computer. With the implementation of git, everyone on the team can work on any file at any time. Git tracks changes and allows its users to merge all the changes to a common version. Another benefit of git for web developers is it’s ability to efficiently and effectively store versions of code with the option of restoring previous versions if you mess up on a new edit.
Git helps keep track of changes by treating your history as a tree of changes. You can create your working tree by starting your own project or cloning an existing repository (from GitHub) to your computer. Tracking branches get their content from “git clone” and can be modified by users. Changes to the branch can be saved with the “git add .” and “git commit” commands.
Git and GitHub are not the same thing. GitHub is a place to remotely store working directories and share your own repo’s publicly or with a team. Web developers use GitHub because it’s an excellent collaboration tool, allowing you to push, pull and merge repositories.

XREFRESH
Section: User Commands (1)Updated: xrefresh 1.0.4
Index Return to Main Contents
NAME
xrefresh - refresh all or part of an X screenSYNOPSIS
xrefresh [-option ...]DESCRIPTION
Xrefresh is a simple X program that causes all or part of your screen to be repainted. This is useful when system messages have messed up your screen. Xrefresh maps a window on top of the desired area of the screen and then immediately unmaps it, causing refresh events to be sent to all applications. By default, a window with no background is used, causing all applications to repaint ``smoothly.'' However, the various options can be used to indicate that a solid background (of any color) or the root window background should be used instead.
ARGUMENTS
- -white
- Use a white background. The screen just appears to flash quickly, and then repaint.
- -black
- Use a black background (in effect, turning off all of the electron guns to the tube). This can be somewhat disorienting as everything goes black for a moment.
- -solid color
- Use a solid background of the specified color. Try green.
- -root
- Use the root window background.
- -none
- This is the default. All of the windows simply repaint.
- -geometry WxH+X+Y
- Specifies the portion of the screen to be repainted; see X(7).
- -display display
- This argument allows you to specify the server and screen to refresh; see X(7).
X DEFAULTS
The xrefresh program uses the routine XGetDefault(3) to read defaults, so its resource names are all capitalized.
- Black, White, Solid, None, Root
- Determines what sort of window background to use.
- Geometry
- Determines the area to refresh. Not very useful.
ENVIRONMENT
- DISPLAY - To get default host and display number.
SEE ALSO
X(7)BUGS
It should have just one default type for the background.

(So it was) till then there came Our Command and the oven gushed forth (water like fountains from the earth). We said: "Embark therein, of each kind two (male and female), and your family, except him against whom the Word has already gone forth, and those who believe. And none believed with him, except a few." |
| 011:040 Maulana | : |
At length when Our command came and water gushed forth from the valley, We said: Carry in it two of all things, a pair, and thine own family -- except those against whom the word has already gone forth -- and those who believe. And there believed not with him but a few. |
| 011:040 Pickthal | : |
(Thus it was) till, when Our commandment came to pass and the oven gushed forth water, We said: Load therein two of every kind, a pair (the male and female), and thy household, save him against whom the word hath gone forth already, and those who believe. And but a few were they who believed with him. |
| 011:040 Rashad | : |
When our judgment came, and the atmosphere boiled over, we said, "Carry on it a pair of each kind, together with your family, except those who are condemned. Carry with you those who have believed," and only a few have believed with him. |
| 011:040 Sarwar | : |
When at last Our decree was fulfilled, water gushed forth from the Oven (in Noah's house). We told him to carry in the Ark a pair (male and female) from every species, his family - except those who were destined to perish - and the believers. No one believed in him, except a few. |
| 011:040 Shakir | : |
Until when Our command came and water came forth from the valley, We said: Carry in it two of all things, a pair, and your own family-- except those against whom the word has already gone forth, and those who believe. And there believed not with him but a few. |
| 011:040 Sherali | : |
Till -- when our command came and the fountains of the earth gushed forth - WE said, 'Embark therein two of every kind, male and female, and thy family, except those against whom the word has already gone forth, and those who believe.' And there had not believe in him except a few. |
| 011:040 Yusufali | : |
At length, behold! there came Our command, and the fountains of the earth gushed forth! We said: "Embark therein, of each kind two, male and female, and your family - except those against whom the word has already gone forth,- and the Believers." but only a few believed with him. |

HyFed (Hybrid Federated) is a framework for privacy-preserving machine learning. It provides an easy-to-use API to develop federated learning based algorithms, where each client (1) obtains the global parameters from the server, (2) computes the local parameters from its private data and global parameters, (3) perturbs the local parameters with noise, and (4) shares the noisy local parameters with the server and noise with the compensator. The compensator aggregates the noise values from the clients and sends the resulting aggregated noise to the server. The server aggregates the noisy local parameters and the negative of the aggregated noise to compute the global parameters.

Which of these is not a defining property of a flyweight?
There is only one copy of the flyweight (that is shared).
Since a flyweight is reused, the implementor cannot count on its ability to store state (since all occurrances are the same.
It doesn't matter how big the flyweight is.
