When using heroku container:release -a MyApp web I get error: process type already running the specified docker image

Question

I'm using Heroku with Docker. When pushing my image with:

heroku container:release -a MyApp web 

My console returns:

The process type web was not updated, because it is already running the specified docker image

Someone knows what going on here ? I have never pushed this image in my app.

Any hint would be great.

Answer 1

You need to build the images, before pushing it.

so run this command:

heroku container:push web --app application-name

and then try to run

heroku container:release  web --app application-name
