WordPress Cloud Run CI/CD Setup

I already have WordPress containerised and running under its own domain; what’s missing is the move to Google Cloud Run and a clean, automated Git-based deployment workflow. I’d like you to:

• Deploy the existing container image to Google Cloud Run, making sure the current domain keeps resolving without disruption.
• Wire everything into GitLab CI with a straightforward build-and-deploy pipeline so every push to the main branch automatically rebuilds the image and rolls it out to Cloud Run.

No extra environments beyond production are needed, so the pipeline can stay lean. If secrets, variables or IAM permissions are required for the deploy stage, please document the steps you take so I can maintain them later. Once the job is done I should be able to run a git push and watch GitLab handle the rest all the way to a live site on Cloud Run.
