I am setting up nodes to use the containerd runtime but want docker installed on some of them too, after running init with the containerd settings is there a way to check k8s is talking to containerd directly?
If you run kubectl describe node <yournode> there should be a line called Container Runtime Version under the system info heading.
For example mine reads: Container Runtime Version: docker://18.9.6
You could also add a label to the nodes as well.
