I started learning about containerization just this week. I didn't even know there were other popular alternatives to docker. So from what I gather, coreOS/rkt is an alternative to alpine/docker, with kubernetes instead of docker swarm as their primary orchestration solution?

no. there is no clear distinction like that with coreOS. Its just one of the distributions that try to be a ... docker hypervisor for lack of a better term. It tries to be a tiny distribution for the sole purpose of letting you use a docker daemon. a direct competitor would be RancherOS /edit: furthermore, the kubernetes docker daemon is (afaik) a fork from the original docker and predates docker swarm by a long time. It was the only way to really scale with docker back then. Docker Swarm seems to be a viable alternative at this point, however. And honestly, its way easier to use from my experience.

Calling rkt a competitor to docker would be a stretch. Docker has undergone really vast improvements since its inception which is not really true for rkt.
