Description

After setting up gitea on Docker using a user called "gitea", creating a user and adding its public key, cloning fails with the Permission denied (publickey) error.

I looked into this and found something strange - in /etc/ssh/sshd_config, the AllowedUsers directive showed giteaea instead of gitea. In fact, every time I restarted the container, the user gained another "ea" at the end - so it went to giteaeaea etc. Changing the directive back to gitea manually doesn't help, because during startup it changes to giteaea.

My workaround: I copied /etc/ssh/sshd_config from the container to the host, and bound it into the container, setting the :ro flag so it would be immutable.

Did you pass the USER environment variable to the container?

If yes, then it is likely because of this line:

gitea/docker/usr/bin/entrypoint

Line 7 in 801843b

sed -i -e "s/AllowUsers git/AllowUsers ${USER}/g" /etc/ssh/sshd_config

It seems the regex should grep for AllowUsers git on a line, instead of search for that string where it could be the middle.
