Heroku: docker deploy throws unauthorized: authentication required

docker heroku

The same error occurred to me. I just ran the command below and it worked.

heroku container:login

docker heroku

Yes, as the original answer points out first run

heroku container:login

But also ensure that the docker image is tagged correctly with the following naming convention:

docker tag <image> registry.heroku.com/<app>/<process-type>

<app> should exactly match your apps name in the dashboard of Heroku.

docker heroku

docker hub login before

heroku container:login

andheroku container:push web --app app_name

heroku container:release web --app app_name

worked for me
