docker-sops

What is this?

I wanted to try out SOPS on my Raspberry Pi and there was no ARM version available. Thought I'd Dockerize it. I have a bash function in my .bash_profile to then run the container.

Bash function example

function docker-sops { 
        docker run -it --rm \
          --name docker-sops \
          -v $(pwd):/home -v $HOME/.gnupg:/root/.gnupg \
          rakheshster/sops:latest $@ ;
}

This pulls the image from DockerHub, calls it "docker-sops" (the name doesn't matter), mounts the current directory as "/home" in the container (so sops can work on it), mounts the ".gnupg" directory in your home folder into the container (so sops & gnupg can access your keys), and runs the container with the arguments to the function passed to it. Simple!

I invoke this as docker-sops <whatever>. I could have called the function sops but I decided to prefix it with docker- in case I install an ARM binary of sops later. You could call the function sops if you want.
