Docker images pushed from CircleCI to Herouku doesn't work

Hi all,

I follow instructions from here and here to build Docker image in CircleCI and push it to Heroku.

All looks ok, build and push is successful but application doesn’t work with error:

Now the trick, pull the deployed image from Heroku:

sudo docker pull

Status: Downloaded newer image for

And push the absolutely same image back:

sudo docker push                                                                                                                           

The push refers to a repository []

Pay attention all layers exists this is exactly the same image. And now… all works!

I have been fighting with this issue about 3 days.

There is circle.yml:

    - docker

    - docker info
    - docker login -e $DOCKER_EMAIL -u $DOCKER_USER -p $DOCKER_PASS
    - docker build --rm=false -t mycompany/dl-extensions .

    - docker run -d -p 8888:8888 mycompany/dl-extensions
    - curl --retry 10 --retry-delay 5 -v http://localhost:8888

    branch: continious-deployable
      # Push image to Docker Hub
      - docker push mycompany/dl-extensions

      # Push image to Heroku
      - docker login --email=_ --username=_ --password=$HEROKU_API_KEY
      - docker tag mycompany/dl-extensions
      - docker push
