I am running several k3s clusters that I am upgrading from a Rancher 2 server.
I noticed that k3s is upgraded correctly, but the containerd version did not change since the initial installation.
$ sudo k3s --version
k3s version v1.18.8+k3s1 (6b595318)
$ sudo k3s ctr version
Latest rancher/containerd release seems to be v1.3.6-k3s2.
Is v1.3.3-k3s2 the right version for k3s v1.18.8+k3s1 or is there another way to upgrade it?
