Tips

A CI/CD variable contains a $

If a gitlab cicd variable contains a $, we can escape it addin another $ in the value

asljfrower$34onamdgflg > asljfrower$$34onamdgflg

Credentials to pull image

• create a credential with pull permissions in your registry

• Add a masked variable to the CI/CD with this format

name: DOCKER_AUTH_CONFIG
value: {"auths":{"FQDN":{"username":"your-username","password":"your-password"}}}

And thats it. GitLab will automatically use these credentials to authenticate with your registry. The authentication happens at the GitLab Runner level, not within your job container.
