git-sync asking for password even while using ssh-key-file

[rishabhgargg]

With the following docker command:

docker run -it --rm -v $PWD/git-sync-essentials:/work -w /work -v $PWD/git-sync-cloned:/git-sync-cloned -v $PWD/destination:/destination --entrypoint sh registry.k8s.io/git-sync/git-sync:v3.6.9

Note: git-sync-cloned, git-sync-essentials, destination all have ownership user:group as 65533:65533

I am running the git-sync:v3.6.9 container on my machine. Inside it, when I am executing following command:

/git-sync -ssh -v=2 -ssh-key-file=/work/id_rsa -ssh-known-hosts=false -dest=/destination -root=/git-sync-cloned -repo=git@<repo_url>

With this setup, I am getting the following error, I have tried it multiple time, but this doesn't seem to work.

 docker run -it --rm -v $PWD/git-sync-essentials:/work -w /work -v $PWD/git-sync-cloned:/git-sync-cloned -v $PWD/destination:/destination --entrypoint sh registry.k8s.io/git-sync/git-sync:v3.6.9
$ /git-sync -ssh -v=2 -ssh-key-file=/work/id_rsa -ssh-known-hosts=false -dest=/destination -root=/git-sync-cloned -repo=git@gitlab.<example>.com:<username>/<repo>.git

git@gitlab.<example>.com's password:

Do note that, I have used the same key to clone the repo without the git-sync container on my local machine on a fresh ubuntu container and it worked as expected, but I don't know why I am facing issues with this git-sync container.

I don't know that even when I am passing the ssh key, why is it asking me for password, I am stuck here for past 3 days now.

@thockin Any help is appreciated. Thanks in advance.

1. Can you run with -v 6 and show the logs?

2. If you manually run git clone <repo> with the exact repo syntax, what happens?

3. If you can try v4.1.0 that would also help (soem flags have changed between v3 and v4, there's a doc)

The issue was regarding the port, as git sync over ssh uses port 22 (as expected), and it was blocked in my infrastructure and becuase of that reason, even when I supplied the ssh key, it was falling back to https (443).

Thank you for your response.

Thanks for the update!
