Docker-SSH

SSH Server for Docker containers This is an extension of Docker-SSH which adds capability of logging in into multiple Docker containers.

Run one Docker SSH server through which you can connect to multiple Docker containers depending on user.

Features:

• multiContainerAuth authentication method.

Quick start

• build Docker image

docker build -t docker-ssh github.com/maxivak/docker-ssh

• run SSH server in Docker container

docker run -d -p 2222:22 \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -e AUTH_MECHANISM=multiContainerAuth \
  -e AUTH_TUPLES="u1:pwd1:container1;u2:pwd2:container2" \
  docker-ssh

• or specify users with passwords and corresponding containers in a separate file

docker run -d -p 2222:22 \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -e AUTH_MECHANISM=multiContainerAuth \
  -e AUTH_TUPLES_FILE="/auth" \
  -v /path/to/local/file/auth:/auth \
  docker-ssh

where file auth contains data like this:

u1:pwd1:container1
u2:pwd2:container2

• login

# login as user u1 to container1
ssh -p 2222 u1@localhost

# user u1 enters container 'container1'


# login as user u2 to container2
ssh -p 2222 u2@localhost

# user u2 enters container 'container2'
