Building and Deploying Docker Images to Heroku via CircleCI

circleci.yml

machine:
  services:
    - docker

dependencies:
  override:
    - echo "no deps"

test:
  post:
    - echo "yay - no tests"

deployment:
  production:
    branch: master
    commands:
      - docker build -t backer-board .
      - docker login --email=_ --username=_ --password=$HEROKU_TOKEN registry.heroku.com
      - docker tag backer-board:latest registry.heroku.com/backer-board/web
      - docker push registry.heroku.com/backer-board/web

Yes. same question. I've the following in config.yml

- run:
          name: Deploy to Heroku
          command: |
             docker login --username=$HEROKU_LOGIN --password=$HEROKU_API_KEY registry.heroku.com
             docker tag khizarali/dockerized-store:$CIRCLE_SHA1 registry.heroku.com/$HEROKU_APP_NAME/web
             docker push registry.heroku.com/$HEROKU_APP_NAME/web

Here image is pushed to registry.heroku.com and what next to get it up and running on heroku app. something heroku container:release ?
