pull access denied repository does not exist or may require docker login

Question

I am using Laravel 4.2 with docker. I setup it on local. It worked without any problem but when I am trying to setup online using same procedure then I am getting error

Answer 1

Docker might have lost the authentication data. So you'll have to reauthenticate with your registry provider. With AWS for example:

aws ecr get-login --region us-west-2 --no-include-email

And then copy and paste that resulting "docker login..." to authenticated docker.
