Problem with enabled 2FA on local GitLab instance

[hirnschmalz]

Hi there,

I've problems with (I guess) 2FA enabled accounts. The following error message occures while trying to push:

ERROR - Unable to sync repo https://github.com/TYPO3/TYPO3.CMS.git -> https://git.custom-domain.tld/mirror-test/TYPO3.CMS.git (Command "git" "push" "--mirror" "https://git.custom-domain.tld/mirror-test/TYPO3.CMS.git" failed with exit code: 128, Stderr: fatal: could not read Username for 'https://git.custom-domain.tld': terminal prompts disabled

Maybe the reason is the slightly different username/password handling with enabled 2FA?

I'm using the docker image.

Have you tried using SSH instead of HTTP to push to your instance?

[hirnschmalz]

Our local git instance does not allow SSH.

Currently to only way to push to HTTPS is to include the credentials in the URL:

git-mirror -u https://user:[email protected]/

I haven't tried this tough. Let me know if this works.

[hirnschmalz]

This does not work, since this is only used for fetching the repositories inside the group. As far as I can see the URL for pushing is fetched via the GitLab API.

For now I will add .gitconfig and a .git-credential file with the required information.

If you get it working it would be nice if you could write a quick howto that can be included in the README.

Hi @bachp ,

there are two things I had to do

• Enable saving of git credentials via git config credential.helper store
• Save the credentials to the .git-credentials file https://user:[email protected] where the password is the access token

So as far as I can see to make git-mirror working with GitLab 2FA enabled the docker image must respect two new Environment variables

• one two tell that 2FA is enabled
• if 2FA is enabled a username must be provided

With this Information it should be possible to make everything working even if 2FA with http only access.

I need to give it some more tought how this could be improved.

One idea would be to set GIT_ASKPASS and write a small helper that provides the credentials to git from config or environment variables.
