Docker

• Build container

  $ docker build -t gcr.io/PROJECT_ID/APP_NAME:APP_VERSION
  

• Push container to Google image registry

  $ gcloud docker push gcr.io/PROJECT_ID/APP_NAME:APP_VERSION
  

Container Engine

• Deployment config file (e.g. deployment.yaml)

  apiVersion: extensions/v1beta1
  kind: Deployment

          image:  gcr.io/PROJECT_ID/APP_NAME:APP_VERSION
          ports:
          - containerPort: CONTAINER_PORT
