   [Cloud Foundry Command Line Interface (cf CLI)](../../cf-cli/install-go-cli.html) to push an app with a new or updated Docker image. Cloud Foundry then uses the Docker image to create containers for the app.
   
   See [Using Docker in Cloud Foundry](https://docs.cloudfoundry.org/adminguide/docker.html) in the Cloud Foundry documentation for an explanation of how Docker works in Cloud Foundry.

  #### Step 2: Deploy the GCP Image
  
  Run the following command to deploy your GCR image using the cf CLI:
  `CF_DOCKER_PASSWORD="$(cat key.json)" cf push APP-NAME --docker-image docker://MY-REGISTRY-URL/MY-PROJECT/MY-IMAGE-NAME --docker-username _json_key`
  <br>Replace the placeholder values in the command as follows:
  
  
negative.code: 
  <%= vars.app_runtime_abbr %> supports pushing apps from images hosted on Amazon Web Services ECR, which authenticates with temporary password tokens.
  
  * To push an app as a Docker image from ECR:
  
      ```
      $ CF_DOCKER_PASSWORD=AWS_ECR_PASSWORD cf push APP-NAME --docker-image REPO/IMAGE:TAG --docker-username AWS_ECR_USER
      ```
  
      Where:
      - `AWS_ECR_USER`: the user returned by the `aws ecr get-login --no-include-email` command. It usually is `AWS`
          - Setting `CF_DOCKER_PASSWORD` prepended to the `cf push --docker-image` makes the value temporary, which is more secure than setting the environment variable indefinitely with `export`
      - `APP-NAME`: The name to give the pushed app on <%= vars.app_runtime_abbr %>
      - `REPO`: The ECR repository containing the image being pushed
      - `IMAGE`: The name of the app image being pushed
      - `TAG`: (Optional, but recommended) The tag or version for the image
      - `AWS_ECR_PASSWORD`: the long password returned by the `aws ecr get-login --no-include-email` command. 
  
  **How it Works**: Running `cf push` with an ECR registry triggers <%= vars.app_runtime_abbr %> to:
