⁠Usage

The container can be configured through the following environment variables:

  • SSH_PORT change the default ssh port (default is 22)
  • SSH_KEY_SEPARATOR change the public key separator (default is comma)
  • SSH_PUB_KEY set your ssh public key so that you can connect to this container (you can set multiple public keys separated by the character defined in the SSH_KEY_SEPARATOR environment variable)

⁠Deployment examples examples
