[BUG] - Cannot deploy a new version of a docker image

[ivaaaan]

What is the current behavior?

I have created a new app and successfully deployed a docker image. It works, but now I've rebuilt the image and pushed it to the registry. After heroku container:release web I'm getting The process type web was not updated, because it is already running the specified docker image..

Steps to reproduce:

1. Create a new app
2. Build and tag an image locally:

docker build -t api -f Docker/Dockerfile .
docker tag api registry.heroku.com/api/web

3. Release it heroku container:release web
4. Modify Dockerfile and repeat steps 2 and 3.

What is the expected behavior?

A new docker container is created.

Is it even possible to release a new version of your app with docker in heroku?

I tried this out using a very simple example docker app, but I was not able to reproduce the error. @ivaaaan are you still experiencing this issue?
