Summary
In this chapter, we looked at four different tools for launching both single-node and multi-node Kubernetes clusters. We discovered that while the method of launching each of the clusters is slightly different, once they are up and running, you get a mostly consistent experience once you start to interact with them using standard Kubernetes tools like kubectl.
At this point, I should probably confess something: two of the four tools we have covered in this chapter do not actually use Docker in the traditional sense – both MicroK8s and K3s actually use containerd.
As you may recall from Chapter 1, Docker Overview, containerd is an easily embeddable container runtime. It started life at Docker Inc., but the project was donated to the Cloud Native Computing Foundation (CNCF) – it is the container runtime of the Moby project, which Docker uses as its upstream project.
It is not only small and lightweight, but it also offers full OCI Image and OCI Runtime...
