Hello everyone,

I have stumbled across an odd issue when trying to set up an SSH server =
using Alpine as a base for a docker image.
I am getting a "git@localhost: Permission denied (publickey).=E2=80=9D =
error, although the correct key is inside athorized_keys. I have also =
set the correct permissions for the directories.

After a lot of debugging if found out that I recreate the set up =
(install git, openssh, create bare repo) for the root user I am able to =
clone, ssh into the server etc. But as soon as I create a new user =
=E2=80=9Cgit=E2=80=9D and set up a bare repository and authorized_keys I =
start getting the permissions error.

The logs from the ssh server don=E2=80=99t show anything interesting, =
just that the public key is being rejected. Logs on the client side show =
the same.

Here=E2=80=99s my Dockerfile: https://pastebin.com/jPLqJfQc

I would appreciate any pointers because I am not sure what to debug any =
more.

Thanks,
Val=
