Unable to push to registry due to group requirement

[snowe2010]

Describe the bug

For some reason, the quarkus docker plugin requires a group name. #1300 (comment)

This is incorrect. With private ECR registries on AWS there is no need for a group. You push directly to the registry/image name. This restriction seems very arbitrary and should be removed.

Expected behavior

I expect to be able to push to a repository like 1234.dkr.ecr.us-west-2.amazonaws.com/quarkusio without needing a user or group.

Actual behavior

Attempting to set the group to something like

quarkus.container-image.group=""

results in an error message:

We actually use code from Jib for this, so I would propose asking the Jib folks about this.

[snowe2010]

The corresponding Jib code allows for a null user so it still seems like the issue is on quarkus's side.

[geoand]

The code you linked to is not the user for the repository, it's for the OS user as which the process in the container will run.
