Share Git credentials with your container and use ssh access

This is a run down of this article - Link! On how to access your git accounts from within your running devcontainers using SSH.

  1. Add openssh-client to your Dockerfile 
RUN apt-get update && \
    apt-get install -y --no-install-recommends \
        git \
        curl \
        unzip \
        stow \
        zsh \
        openssh-client \ # <-- ADD
    && \
    # Clean up the apt cache to keep the image size small
    rm -rf /var/lib/apt/lists/*
Enter fullscreen mode Exit fullscreen mode
  1. Allow Agent Forwarding 
Host s1
    HostName stash.stil.dk
    AddKeysToAgent yes
    User x151998
    UseKeychain yes
    IdentityFile  ~/.ssh/id_rsa.stil
    ForwardAgent yes # <-- ADD
Enter fullscreen mode Exit fullscreen mode
  1. Start your devcontainer

How to test the setup

root# echo $SSH_AUTH_SOCK
/tmp/vscode-ssh-auth-secret.sock
root# ssh-add -l
2048 SHA256:finger sukkerfrit@secret.local (RSA)

root# ssh -T git@github.com
Hi sukkergris! You've successfully authenticated, but GitHub does not provide shell access.

Now let's enable the usage of aliases!

  1. Add .ssh to your dotfiles 
Host g1
    HostName github.com
    User git
    ForwardAgent yes
    PreferredAuthentications publickey
Enter fullscreen mode Exit fullscreen mode

So, if you like me ara using aliases you can now use git from within your container :)

Vola!
