version: 0.1.1

The current guide is the optional step and can be involved only after provided Deployment Marionette Exchange System
You should use the same VM for deployment as was used in the pointed "Deployment Marionette Exchange System on Stage" guide.

Also, you need a root level access to the operation system of your PC, basic knowledge on Git and SSH as well, an account on TuneX Gitlab (address: gitlab.tunex.io).
If you don't match some of these requirements please read the manual carefully and use the explanations provided as links to external resources.

Gitlab-runner is a tool for executing instructions from a special ".gitlab-ci.yml" file. In the scope of current guide Girlab-runner automates the rendering of compose and template files and restarting services on each change in the Marionette project. Of course, it make sense only after after finished initial deployment of the Marionette Exchange System

1. Install Gitlab Runner for Deployment

If you are a client and can't perform the actions below yourself, or you are not sure experienced in this topic enough, please contact us and our support will execute this part on your behalf.

1.1. Take hint for install and register Group gitlab-runner on TuneX Gitlab

Note: The Group gitlab-runner can be used for any CI/CD jobs for each project of your Group on TuneX Gitab. That is the main reason to create one Group runner instead of several runners for each project inside your Group on TuneX Gitab.

1.1.1. Open Gitlab menu Settings -> CI/CD inside your Gitlab group on the TuneX Gitlab and push 'Expand' button for runners:

1.1.2. On expanded runners click "Take me there":

1.1.3. Get runners page and click there on "Register a group runners' and push "Show runner installation adn registration instructions":

1.1.4. Use window for next guide steps to install and register runner:

1.2. Connect to VM and install gitlab-runner

Run to connect the VM:

ssh root@[IP address]

where [IP address] - the address of the VM for deploy

You should got something like:

Below used "Download and install binary" from step 1.1.4

Install Gitlab runner (recommend binary install: https://docs.gitlab.com/runner/install/linux-manually.html#install-1 ):

curl -L --output /usr/local/bin/gitlab-runner "https://gitlab-runner-downloads.s3.amazonaws.com/latest/binaries/gitlab-runner-linux-amd64"

Give permissions to execute gitlab-runner

Run next command to add execute permissions:

chmod +x /usr/local/bin/gitlab-runner

create a GitLab CI user:

useradd --comment 'GitLab Runner' --create-home gitlab-runner --shell /bin/bash

install and run as service:

gitlab-runner install --user=gitlab-runner --working-directory=/home/gitlab-runner

gitlab-runner start

1.3. Add user gitlab-runner to sudoers and to docker group

usermod -aG sudo gitlab-runner

usermod -aG docker gitlab-runner

Enable sudo without password for gitlab-runner by next command:

visudo

!!! You should never edit /etc/sudoers with a regular text editor, such as Vim or nano, because they do not validate the syntax like the visudo editor

To the end of the opened /etc/sudoers file add this line:

gitlab-runner    ALL=(ALL) NOPASSWD:ALL

e.g.:

and save changes

2. Register Group gitlab-runner

Connect to the VM again (in case you exit or loose connection):

ssh root@[IP address]

where [IP address] - the address of the VM for deploy

2.1. Register Group gitlab-runner on VM for deploy in TuneX Gitlab

Use "Command to register runner" from the step 1.1.4:

Here is command for register gitlab-runner:

gitlab-runner register --url https://gitlab.tunex.io/ --registration-token [Registration token]

where [Registration token] copied from "Command to register runner"

Just copy row from "Command to register runner", run it and answer the questions like on the screen:

For success working of the gitlab-runner for CI-CD task rename .bash_logout to .bash_logout.back in the runner home directory:

cd /home/gitlab-runner/
mv .bash_logout .bash_logout.back

Make sure you have .bash_logout.back inside /home/gitlab-runner folder, type command:

cd /home/gitlab-runner/
ls -lha

get similar to the screen:

Restart gitlab-runner service:

service gitlab-runner-restart

Check the status of gitlab-runner:

service gitlab-runner status

You should get green active (running) status:

Use "Ctrl+C" on the keyboard to exit the status window of gitlab-runner.

2.2. Check registration of the Group gitlab-runner on the TuneX Gitlab

2.2.1. Open Gitlab menu Settings -> CI/CD inside Your group and push 'Expand' button for runners:

2.2.2. On expanded runners click "Take me there":

2.2.3 Check the gitlab-runner is available in the list of Group runners

Here is an example of available gitlab-runner and pointed VM IP and answers during runner register:

3. Set Group gitlab-runner to CI/CD job and run pipeline for deploy
