 Docker-SSH adds SSH capabilities to any container in a compositional way. It implements an SSH server that transparently
 bridges the SSH session with docker exec. The requirements for this to function properly are:
 
-- The container has a shell environment installed (e.g. `bash` or `sh`)
-- The Docker command and docker socket are mapped into the container

 Let's assume you have a running container with name 'web-server1'. Run the following command to start Docker-SSH:

-    --name sshd-web-server1 -p 2222:22  --rm \

 The SSH server in this example is now running in its own container named 'sshd-web-server1' and exposes the SSH
 service on port 2222.
