eigrad/ssh-ambassador repository overview

⁠eigrad/ssh-ambassador docker image

Lightweight ssh client container based on alpine linux image. Suitable to be used as docker ambassador container for containers located on different hosts connected over the insecure network.

⁠Example usage

docker run -d \
  --name mysql_ambassador \
  -v .ssh:/keys \
  eigrad/ssh-ambassador [email protected] 3306 \
  -p 3022  # if ssh uses the custom port on server

docker run -d --link mysql_ambassador:mysql examplecom/wordpress

Default ssh_config expects to find the id_rsa key and the known_hosts file in the /keys directory. Password authentication and host key adding are disabled (ensure that the key of the host where you would like to connect is already added to the known_hosts file).

Of course, you can override it by -v your_own_ssh_config:/etc/ssh/ssh_config.

It is also possible to pass an additional ssh parameters after the service port number in the command:

docker run -d \
  --name mysql_ambassador \
  -v .ssh:/keys \
  eigrad/ssh-ambassador example.com 12345 \
  -o StrictHostKeyChecking=no \
  -o UserKnownHostsFile=/dev/null

⁠Environment variables

• TARGET_HOST - host to connect on the remote side (default: localhost)

• EXPOSED_PORT - port to expose (bind) on the local side (default: equal to the service port)
