# Build using: 
docker build -t eg_sshd .

# from
# https://docs.docker.com/engine/examples/running_ssh_service/



# Then run it. You can then use docker port to find out what host port the container’s port 22 is mapped to:
#
#  docker run -d -P --name test_sshd eg_sshd
#  docker port test_sshd 22
