Docker Ssh To Container As Root Free Intro To

Using docker ps I obtained the CONTAINER ID, and then used docker inspect grep IPA to obtain the IP address for the running container.

The entry that begins The scenario you described is the correct solution.

While some questions about Docker are loosely programming-related, this one is not.

This is a network sys admin question, and is no different than How do I enable SSH in Linux.

Therefore, the IP address of the container cannot be used in this way on the Mac.

Error EADDRINUSE means that this address already in use in case if you meet this error once more.

If you want to use ssh and ensure that an ssh daemon is up and running you should expose corresponding ports from the container with -p parameter like this: docker run -d -p 22:22 myimage.

Start Learning Docker Updated on May 25th, 2018 in docker Docker Tip 56: Volume Mounting SSH Keys into a Docker Container On paper this sounds easy.

Just mount in your SSH directory and youre done, but its not that simple with Windows based Docker hosts.

It starts off easy.

Just run: docker run --rm -it -v.ssh:root.ssh:ro alpine.

If youre running Linux or MacOS, thats all you need to do.

I like adding in the extra:ro bit to the volume mount to make it read-only.

This just removes the possibility of you overriding your SSH keys in the container by accident.

But What about Windows (specifically WSL) Theres 2 problems.

PROBLEM 1. Permissions are busted: Unfortunately Windows doesnt respect Linux file permissions.

Your SSH folder and files will all be set to 777 and SSH wont work with those permissions.

As of Windows 10 Spring 2018 edition, you can mount in your drives into WSL using metadata which supports Linux file permissions, and thats fantastic, but Docker for Windows mounts that drive in through CIFS and that will strip out the metadata.

So youre stuck with 777 permissions when mounting in your SSH keys through Windows.

PROBLEM 2. You cant Docker volume mount files from directly inside of WSL: In addition to the above problem, you cant mount in files that exist directly in your WSL drive.

They will come up empty, so mounting.ssh doesnt work.

But you can get around this one easy enough.

You just need to copy your SSH keys to somewhere that gets mounted into WSL, rather than living directly in WSLs file system.

Fixing the problem with a Docker ENTRYPOINT script: First up, make a docker-entrypoint.sh script in the same directory as your Dockerfile.

Then when the container starts, the ENTRYPOINT kicks in and copies everything to the correct location with the correct permissions.

Problem solved, you can now use your SSH keys If youre a Docker image author and you require users to volume mount in their SSH keys, please think about people running Windows by including the above ENTRYPOINT script.
