My chromebook (Samsung 550 from 2012) can not run the Docker daemon (see here for technical explanation), which is sad and makes it next to useless in a modern DevOps project.
RKT to the rescue
BUT it runs regular Docker images just fine with CoreOS RKT !
Follow these install instructions to install RKT, nothing special required.
Proof you say ?
OK, let´s start a shell with rkt and Redis and netcat to it from a second shell. How does that sound ?
rkt with Redis
Using crouton (Ubunty trusty) to launch a terminal and starting the standard Redis container.
--net=host is required to expose the port to the host and use the prefix
docker:// to fetch images from the Docker repo.
sudo rkt run --net=host docker://redis
info to Redis
So for me this allows me to run Docker containers on my Chromebook, something I was missing last year.
