WIP: Bump Kubernetes to v1.17.9 #69

Closed anton-johansson closed 3 years ago

anton-johansson commented 4 years ago

NOTE: Not fully tested. Do not merge.

Kubernetes changelog can be found here: https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG/CHANGELOG-1.17.md

Version bumps other than Kubernetes ones

etcd

etcd was bumped from 3.3.15 to 3.4.3, because this was found in the changelog:

Update etcd client side to v3.4.3 (kubernetes/kubernetes#83987, @wenjiaswe) Update default etcd server version to 3.4.3 (kubernetes/kubernetes#84329, @jingyih)

An upgrade from 3.3 to 3.4 should be zero-downtime using a regular rolling upgrade, according to their own documentation: https://etcd.io/docs/v3.3.12/upgrades/upgrade_3_4/

CNI plugins

The CNI plugins was bumped from 0.7.5 to 0.8.6, because this was found in this changelog:

Update CNI to v0.8.6

Note that this bump was performed in Kubernetes 1.17.7, but since we're bumping to 1.17.9, this feels very appropriate. :)

Other

I don't see anything related to runc or containerd - however - we probably never see that in their changelog since there are different container runtimes. But the current versions of containerd and runc that we use are both released after Kubernetes 1.17, so I think we can leave these as is for now, and maybe revisit this for the 1.18 bump. Or what do you think @amimof?

Breaking changes

I could not find any breaking changes or deprecations regarding the command line parameters to the various services (kube-apiserver etc).

@anton-johansson awesome work. Everything looks good to me. There is a CI build error though. I'll check it out. Regarding containerd and runc, lets keep current versions for now.

anton-johansson commented 4 years ago

Sounds good! Build is now fixed. Let me perform some real-cluster tests before we proceed here.

I'm actually not backing up my etcd yet, and since this PR involves a version-bump of etcd, this is a perfect opportunity to fix that first. :) So it might take some time before I can resume this.

If you (or anyone else) need 1.17 before I can resume, feel free to take over!

Closing in favor of #71.
