Deploying ElasTest on a Linux server

Through the following lines you will find a guide to deploy ElasTest on a single machine (physical or virtual). So the same steps can be applied to a server on your data center or an instance on AWS, OpenStack, Azure or Google Cloud.

We've tried to deploy ElasTest on Ubuntu 16.04, Ubuntu 18.04 and CentOS 7 and the steps are basically the same.

You only need remote or physical access to a Linux interactive shell to run commands as a privilegiated user.

You can also deploy ElasTest on Amazon Web Services

Depends on your infraestructure the access will be different. Please, refer to your system administrator to know how to grant access to the console.

First of all, you'll need to install Docker, please, refer to the official documentation to install onto your platform:

Ubuntu

Centos

If you want to use docker with a regular user add the user to docker group:

sudo usermod -aG docker YOUR_USER

In order to launch ElasTest platform just type

docker run -ti \
  --rm \
  -v ~/.elastest:/data \
  -v /var/run/docker.sock:/var/run/docker.sock \
  elastest/platform start \
  --server-address=X.Y.Z.W \
  --testlink \
  --jenkins \
  --user=xxxxxx \
  --password=yyyyyy

ElasTest needs to use Docker to launch other containers, so we bind the socket as a volume inside the platform.

The server-address is web address you will reach the platform. If you're deploying on a cloud provider (like AWS, GCE o Azure) this address should be your public IP, if you're deploying on your private LAN this is the address you're using to connect the server.It's necessary to use the --server-address option and also open all ports from 32768 to 61000 both included. It is highly recommended to also set user and password using the --user and --pass options.

Alternatively, you can use a domain name like elastest.my_company.com for the server_address parameter.

--testlink stands for TestLink and --jenkins stands for Jenkins. These fields are not obligatory but its use is recommended.

You can also use your own Jenkins and install the ElasTest plugin for Jenkins

Finally, set user and password to grant access to the platform. You can omit this parameters if you're working on a safe evironment.

You'll see the following lines on the terminal when the platform is up and ready

Pulling some necessary images...

Preload images finished.

Starting ElasTest Platform (normal mode)...

ElasTest services are starting. This will likely take some time. The ElasTest URL will be shown when ready.

ElasTest Platform is available at http://X.Y.Z.W:37000

Press Ctrl+C to stop.

It'll show the domain name instead the IP address in the case you're using a DNS service.

Type the following command to get more information about start command:

docker run --rm -v ~/.elastest:/data -v /var/run/docker.sock:/var/run/docker.sock elastest/platform start --help
Options

You can include the option --server-address=(docker-machine ip) to set up the machine ip address.

docker run --rm -v ~/.elastest:/data -v /var/run/docker.sock:/var/run/docker.sock elastest/platform start --server-address="myip"

You can set an access username and password using the options --user and --pass (or -u and -p)

docker run --rm -v ~/.elastest:/data -v /var/run/docker.sock:/var/run/docker.sock elastest/platform start --user=elastest --password=elastest

The --logs option allows you to show all the containers logs.

docker run --rm -v ~/.elastest:/data -v /var/run/docker.sock:/var/run/docker.sock elastest/platform start --logs

You can add --testlink if you want to start the TestLink integrated in ElasTest and enable access to it. If you do not add this option, you can start it later manually from the ElasTest GUI.

docker run --rm -v ~/.elastest:/data -v /var/run/docker.sock:/var/run/docker.sock elastest/platform start --testlink

The --jenkins option can be added if you want to start the Jenkins integrated in ElasTest and enable access to it. If you do not add this option, you can start it later manually from the ElasTest GUI.

docker run --rm -v ~/.elastest:/data -v /var/run/docker.sock:/var/run/docker.sock elastest/platform start --jenkins

You can execute --help if you need more information about the options.

docker run --rm -v /var/run/docker.sock:/var/run/docker.sock elastest/platform --help

To start ElasTest automatically on a system with Systemd, two scripts are needed:

1) Start ElasTest (/usr/local/bin/elastest-start)

This script will launch elastest and contains the following lines:

#!/bin/bash
PUBLIC_IP=$(curl ifconfig.co)
nohup docker run -d -v ~/.elastest:/data -v /var/run/docker.sock:/var/run/docker.sock elastest/platform start --server-address=${PUBLIC_IP} &>/dev/null &
disown

exit 0

As you can see, we set less parameters here as the initial configuration was made on the first launch.

For --server-address, we use an external service like ifconfig.co to get the external IP on every launch using curl. This works fine on a cloud provider who give the instance a diferent IP on every boot, nevertheless, if you're using a static IP or a DNS name feel free to change the parameter.

Set execution permissions:

sudo chmod 0755 /usr/local/bin/elastest-start
2) Stop ElasTest (/usr/local/bin/elastest-stop)

The second script is elastest-stop to stop ElasTest.

#!/bin/bash
docker run -d -v /var/run/docker.sock:/var/run/docker.sock elastest/platform stop

Set execution permissions:

sudo chmod 0755 /usr/local/bin/elastest-stop
3) Systemd start script (/etc/systemd/system/elastest.service)
[Unit]
Description=ElasTest Platform
After=docker.service
Requires=docker.service

[Service]
TimeoutStartSec=60
Restart=always
ExecStop=/usr/local/bin/elastest-stop
ExecStart=/usr/local/bin/elastest-start
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

Reload systemd daemon:

sudo systemctl daemon-reload

Enable the service to start with the system

sudo systemctl enable elastest
Start and Stop ElasTest

From now on, everytime you want to launch ElasTest:

sudo systemctl start elastest

or stop

sudo systemctl stop elastest

It is possible that elastest needs some swap space. If your server is physical, it probably has some space already. You can check by running:

free -m

And you should see something like:

              total        used        free      shared  buff/cache   available
Mem:          15921        5059        5278        1130        5582        9337
Swap:           975           0         975

The line labeled as swap shows the swap space. When you have no swap space, it shows this:

              total        used        free      shared  buff/cache   available
Mem:          15921        5059        5278        1130        5582        9337
Swap:             0           0           0

If you're working on the cloud, you'll probably need to add some swap space. To do that follow this steps:

1) Creating a swap file

With Ubuntu:

sudo fallocate -l 4G /swapfile

With Centos:

sudo dd if=/dev/zero of=/swapfile count=4096 bs=1MiB

Both commands will create a 4G file in / called swapfile. You can check it by doing:

ls -lh /swapfile

Now, set up the proper file permissions:

sudo chmod 0600 /swapfile
2) Mark the file as swap space
sudo mkswap /swapfile
3) Activate the swap
sudo swapon /swapfile
4) Checking

If you run the free command again you'll see the swap space available.

free -m
5) Making changes permanent

To make those changes permanent, add the following line to your /etc/fstab file:

sudo echo "/swapfile none swap sw 0 0" >> /etc/fstab

ElasTest makes use of a folder and two volumes to store the data:

/data folder

As you may have seen above in the ElasTest start command, two volumes are binded. The first one is the /data folder that, in the example commands, we have bind to the host's ~/.elastest folder, but you can choose the host folder you want.

In this folder some data like the videos of the tests or configurations of Elastest are saved.

elastest_edm-mysql volume

The elastest_edm-mysql volume contains the ElasTest database, which contains all the data information of the tests, such as projects, suts, monitoring traces, test results, etc.

elastest_etm-testlink volume

The elastest_etm-testlink volume contains TestLink configuration information, such as the name of the MySql schema created in the database of elastest_edm-mysql volume.
