Trigger VyOS basic tasks via Gitlab

This lab requires attendees to run same VyOS basic deployment playbook again as they did on day 2 but this time trigger via Gitlab instead of Ansible command line.

Step 1 - Ensure previous lab task has been completed and Ansible container exists at the container registry

Step 2 - Ensure vyos-basic-setup.yml playbook exists at desired path i.e /home/a01/git-repo/vyos-basic-setup.yml

Step 3 - Ensure inventory file exists at the desired path i.e /home/a01/git-repo/inventory

Note: These paths/files names can be changed but the same must be reflecting at Gitlab CI/CD configuration.

Step 4 - Update .gitlab-ci.yml This can be done locally & changes can be pushed. It is advised to do this via Gitlab itself so that integrated linter can be used.

Add a new stage in existing file for this

stages:
  - Docker build
  - Setup

Next, add the job to trigger the playbook using Ansible docker image:

vyos_basic_setup:
  image: "$CI_REGISTRY_IMAGE:latest"
  stage: Setup
  script:
    - eval $(ssh-agent -s)
    - echo "$SSH_PRIVATE_KEY" | tr -d '\r' | ssh-add -
    - ansible-playbook -i inventory vyos-basic-setup.yml
    - exit 
  when: manual  

Step 5 - Add your SSH private key from server on Gitlab as a variable cat /home/a01/.ssh/id_rsa select the output and copy. Next go to your Gitlab project > Settings (from left sidebar) > CI/CD > Variables and click expand. Click on add variable Add the key as - SSH_PRIVATE_KEY and paste your SSH private key from server as the value and click add.

Next, trigger this playbook manually from web UI and ensure it works.
