How to deploy to cloud RUN from GitLab CI

In this article, I will demonstrate the list of steps to deploy to Cloud Run from your GitLab repository.

For that, you need to have:

• Gitlab repository
• GCP project

In the GCP project, you MUST follow steps bellow:

• activate API fro Cloud RUN
• create a service account having as IAM roles: Cloud Run Admin & Run Service Agent
• create key (json format) for the created service account

In your Gitlab repository, you MUST create:

• .gitlab-ci.yml
• upload the service account key file in the (CI / CD Settings -> variable).

I decided to pusblish docker image to Cloud Registry (I will move to Cloud Artifact Registry asap), then I deploy the last published image to cloud Run.

Below, the two stages that allow you to do that:

• Fist, I build the docker image, tag it and then push it to Cloud Registry

docker-build:
  stage: package
  script:
       - echo "********  Starting docker build & gcr push ********"
    - docker login -u _json_key --password-stdin https://eu.gcr.io < "$GCR_CREDENTIAL"
    - docker build -t api .
    - docker tag api eu.gcr.io/$GCP_PROJECT_ID/api
    - docker push eu.gcr.io/$GCP_PROJECT_ID/api

• Then, I deploy it to a cloud RUN (already created using GCP Consol)

deploy:
  when: manual
  stage: deploy
  image: google/cloud-sdk
  services:
    - docker:dind
  script:
    - gcloud config set project $GCP_PROJECT_ID
    - gcloud auth activate-service-account --key-file "$CLOUD_RUN_DEPLOYER"
    - gcloud run deploy CLOUD_RUN__SERVICE_NAME --image eu.gcr.io/$GCP_PROJECT_ID/api:latest --platform=managed --region=europe-west1 --project=$GCP_PROJECT_ID

Let’s build :) !
