When you run kubeadm join
, it is falling down with the next preflight check:
[preflight] Some fatal errors occurred:
[ERROR SystemVerification]: unsupported graph driver: zfs
Succesful join to the cluster
Use zfs and docker with --storage-driver zfs
Temprorary solution for run kubeadm
with --ignore-preflight-errors=SystemVerification
flag.

google says that people are actually running zfs +docker + k8s, so i'm going to assume that it just works.
but we don't treat zfs
as valid here:
https://github.com/kubernetes/kubernetes/blob/master/test/e2e_node/system/docker_validator.go#L92
should i just add zfs
to the GraphDriver
slice?

For me zfs is working fine in test instances. We going to use it in production.
looks like this was fixed in https://github.com/kubernetes/kubernetes/pull/65635
