bentastic27/tinysshd-jumpbox repository overview

⁠tinysshd-jumpbox

Docker container to be used as a tinysshd jumpbox

⁠usage

You need to mount a dir containing a file named authorized_keys (list of public keys) to /keys-src on the container.

docker run -v /dir/containing/authorized_keys:/key-src -p 22:22 bentastic27/tinysshd-jumpbox

Per tinysshd it will only work with ed25519 keys. So you will need to generate with something like following:

ssh-keygen -o -a 100 -t ed25519 -f ~/.ssh/id_ed25519

Once you put the public key generated from the last command into the aforemented authorized_keys file and mount it appropriately, this will work:

ssh -i .ssh/id_ed25519 root@localhost
