gistfile1.md

Make cache (S3) works with Gitlab and K8S (gitlab-managed-apps)

1. Add secret carries your aws keys:

kubectl create secret generic runner-secrets --from-literal=CACHE_S3_ACCESS_KEY="" --from-literal=CACHE_S3_SECRET_KEY="" -n gitlab-managed-apps

2. Specify cache env vars:

kubectl edit deploy runner-gitlab-runner -n gitlab-managed-apps then add:

        - name: CACHE_TYPE
          value: s3
        - name: CACHE_SHARED
          value: "true"
        - name: CACHE_S3_SERVER_ADDRESS
          value: s3.amazonaws.com
        - name: CACHE_S3_BUCKET_LOCATION
          value: us-east-1          
        - name: CACHE_S3_ACCESS_KEY
          valueFrom:
            secretKeyRef:
              key: CACHE_S3_ACCESS_KEY
              name: runner-secrets
        - name: CACHE_S3_SECRET_KEY
          valueFrom:
            secretKeyRef:
              key: CACHE_S3_SECRET_KEY
              name: runner-secrets
        - name: CACHE_S3_BUCKET_NAME
          value: your-s3-bucket
        - name: CACHE_S3_INSECURE
          value: "false"

3. restart

kubectl rollout restart deployment/runner-gitlab-runner -n gitlab-managed-apps
