The current implementation is running v2.2.1 which is two year old and end of life. This PR add the ability to use etcd and set the versions if required. Note at the moment the image is still using the gcr.io registry image. As note, much like TLS their presently is not 'automated' migration path from v2 to v3.
- the feature is gated behine the storageType of the etcd cluster, bot clusters events and main must use the same storage type
- the version for v2 is unchanged and pinned at v2.2.1 with v2 using v3.0.17
- @question: we shoudl consider allowing the use to override the images though I think this should be addresses more generically, than one offs here and then. I know chris is working on a asset registry??
User reports of kubelet flags not being passed; moved more to code.
Also found & fixed the likely root-cause issue: we have two copies of
the cluster spec and were not being precise about which one we wanted to
use at all times.
