You don’t need to install SSHd on your Docker containers.. However, the method you use has changed. Now Docker has the exec command to do this for you.

If you have a container named my-app-container then you would run:

$ docker exec -it my-app-container bash

To open a bash shell in your container.

As an added bonus, if you’re in development and you want to get into your Docker VM then the easiest way is to run:

$ docker-machine ssh [docker_vm_name]

For most of us using the default VM it would look like this:

$ docker-machine ssh default

Once you’ve opened ssh into your VM, then you can run the docker exec command at the top.
