Kubernetes changelog

CNI remains unchanged at v0.7.5. (kubernetes/kubernetes#75455)

We have v0.7.5 already, so we're fine.

Default etcd server version remains unchanged at v3.3.10. The etcd client version was updated to v3.3.10. (kubernetes/kubernetes#71615, kubernetes/kubernetes#70168, kubernetes/kubernetes#76917)

We have v3.3.12, so we must be fine! :)

I haven't found any service options that we use that has been deprecated.

Testing

  • Creating a new cluster with 1.15, add basic things to the cluster (pod networking, DNS, Ingress controller and a sample deployment)
  • Upgrading an existing 1.14 to 1.15, expect no downtime.

I got a few seconds downtime during an upgrade from 1.14 to 1.15 in a test cluster. It's not really related to Kubernetes version, so I opened up #62 instead.

FYI: I got into issues with CNI after upgrading to 1.15. Turns out I was missing a cniVersion in my flannel config.
