Bump Kubernetes versions to `1.14.1` #45

Closed anton-johansson closed 5 years ago

anton-johansson commented 5 years ago

I never upgraded from 1.13.1 to 1.14.0, i went straight to 1.14.1 using the changes of this pull request.

I do want to highlight that it didn't go as smooth as I'd like. Everything went as expected until the end of the playbook. My NGINX ingress controllers all went down for a short period. I have a hard time figuring out why.

I see these events in my NGINX ingress controller pods:

Warning  Unhealthy  7m23s  kubelet, k8s-nginx-11  Readiness probe failed: HTTP probe failed with statuscode: 500

And I see logs like this from the pods:

Received SIGTERM, shutting down
k8s.io/ingress-nginx/internal/ingress/controller/store/store.go:153: watch of *v1.Service ended with: too old resource version: 18603171 (18603183)

I believe the SIGTERM comes from the readiness probe returning 500, but I can't find any indications for why it would return 500. :(

I don't believe this is related to 1.14.1 though, this would probably have happened if I went to 1.14.0 too, so I think we can ignore that when we review this pull request. It would be nice to know what happened though.
