Containers-roadmap: [EKS] [request]: Support DryRun on API server

[vdboor]

Tell us about your request
Could you enable the DryRun feature gate on the API server?
This feature is available in Kubernetes 1.13, but on 1.12 it's still an alpha feature.

See: https://kubernetes.io/blog/2019/01/14/apiserver-dry-run-and-kubectl-diff/

Which service(s) is this request for?
This could be EKS

Tell us about the problem you're trying to solve. What are you trying to do, and why is it hard?
During deployments, we'd like to use kubectl --server-dry-run to make sure the whole deployment output contains valid Kubernetes syntax. Otherwise, there is a risk of partial deployments.

The used deployment strategy is running: kustomize build | kubectl apply -f -

Are you currently working around this issue?
Not possible.

This also would allow the use of kubectl diff which would be super useful

Any news on that?

Woah, looks like it was sneakily enabled in 1.14 :) Dry run and diff both work!

Dry-run and diff are both stable and available from Kubernetes v1.13 (beta) and Kubernetes 1.18 (stable). Closing this issue as these features are available for all EKS supported versions of Kubernetes.
