Issue with the --username option in docker login when using --password-stdin

[aminelch]

Description

There seems to be an issue with the usage of docker login when providing the --username and --password-stdin options. The --username option is being ignored or misinterpreted when placed after --password-stdin. Based on the official documentation, it should work in this order, but it leads to an error message when executed in this sequence.

Reproduce

Use the following command to log in to a Docker registry:

$ echo "$TARGET_GITLAB_PAT" | docker login -u "$TARGET_GITLAB_USERNAME" --password-stdin registry.gitlab.com
Must provide --username with --password-stdin
Cleaning up project directory and file based variables 00:01
ERROR: Job failed: exit code 1

Expected behavior

Expected Behavior: The --username and --password-stdin options should work regardless of their order, as the documentation clearly specifies both options.

There's an issue with populating your variables. Try this:

Populate the variables:

export TARGET_GITLAB_USERNAME="username"
export TARGET_GITLAB_PAT="pat"

Confirm they're populated:

echo $TARGET_GITLAB_USERNAME     
echo $TARGET_GITLAB_PAT 

Authenticate with GitLab registry:

The following command will succeed regardless of the order of --username and --password-stdin options:

echo "$TARGET_GITLAB_PAT" | docker login registry.gitlab.com --password-stdin -u "$TARGET_GITLAB_USERNAME"
