GitLab Terraform Demo

Some code to create content within a GitLab environment. This will create a public project with a repo and a sample Java app with CI build

Usage

• Ensure you have a GitLab runner for your environment (not really needed - you can ignore this - you just won't have a pipeline run)

  docker run -d --name gitlab-runner --privileged --network host --restart always \
  -v /srv/gitlab-runner/config:/etc/gitlab-runner -v /var/run/docker.sock:/var/run/docker.sock \
  --hostname 172.17.0.3 gitlab/gitlab-runner:latest
  
  export REG_TOKEN="<Your Runner Registration token>"
  docker run --rm -it --privileged --network host -v /srv/gitlab-runner/config:/etc/gitlab-runner \
  gitlab/gitlab-runner --debug -l debug register --non-interactive  --url "http://localhost" \
  --registration-token "$REG_TOKEN" --executor "docker" --docker-image alpine:latest --description "docker-runner" \
  --maintenance-note "Free-form maintainer notes about this runner" --tag-list "docker,aws" \
  --run-untagged="true"  --locked="false" --access-level="not_protected"
  
  # Update the runner to use host network (sigh)
  sudo vi /srv/gitlab-runner/config/config.toml
    # Under [runners.docker]
    network_mode = "host"
  
  # Restart the runner 
  docker ps 
  docker stop gitlab-runner  # Might need the container ID here instead of gitlab-runner
  docker start gitlab-runner

• Log into an existing GitLab server and create a personal access token. In the upper right click your user icon and click Edit Profile. Then on the left menu click 'Access Tokens'. Create a personal access token with all scopes.

  • MAKE CERTAIN THIS IS CALLED Migration Token
  • Direct by URL would be https://YourGitlab.example.com/-/profile/personal_access_tokens

• Clone this repo

• Create a var file like env.tfvars with your environment details

gitlab_token = "glpat-#############"
gitlab_url   ="http://localhost"
##gitlab_url   = "https://YourGitlab.example.com/api/v4/"

• Execute Terraform

apt-get update && apt-get -y install terraform
terraform init
terraform apply -var-file=env.tfvars

Note this will run scripts/java_hello_automation.sh to setup and configure the GitLab CLI and populate some repo content

• Once all done, cleanup:

terraform apply -destroy -var-file=env.tfvars
