feat(eks): support for Kubernetes version 1.23 #22638

kaizencc · 2022-10-25T19:28:18Z

Add support for Kubernetes Version 1.23. In order to use this version, customers must pass in a KubectlLayer object from @aws-cdk/lambda-layer-kubectl-v23 to the kubectlLayer construct prop of Cluster.

New Features

Have you added the new feature to an integration test?
- Did you use yarn integ to deploy the infrastructure and generate the snapshot (i.e. yarn integ without --dry-run)?

The EKS Cluster construct has a property called `kubectlLayer`. When this property was not given, it would add a two default layers to the custom resource: - One with kubectl - One with the AWS CLI However, if the property was given, the one layer must contain both kubectl as well as the AWS CLI. This makes the `kubectl` layer unnecessarily large -- it must also contain the AWS CLI which the CDK already has and can bundle itself. Add a separate `awscliLayer` parameter to control the AWS CLI layer, if the user so wants. If not, the default AWS CLI layer will be added. If some user is already using a `kubectlLayer` which includes the AWS CLI, we now add both the default AWS CLI layer as well as the user's kubectl layer with the AWS CLI in it. There is no conflict: multiple layers can contain the same files. Last layer wins (which is the kubectl layer with the user's preferred AWS CLI).

readme exempt; this is a feature for a new version and the method to include new kubectl versions is already included in the readme.

✅ Updated pull request passes all PRLinter validations. Dissmissing previous PRLinter review.

@pahud We need MVP awards/recognition for each release. I nominate @madeline-k & @kaizencc for the upcoming v2.48.0 release 😃 🎉 🚀

madeline-k

This looks good to me and has my approval! I am not going to officially approve, as I am now a significant co-author, and I'd like someone else in the team to approve.

Is it that it may cause errors or that it will? If we know it will, I think this should be an error.

If not, no issues here.

It is not for certain. In some cases you can use a version of kubectl that is not guaranteed to be compatible with the version of the Kubernetes engine you are using. It just depends on the APIs being used.

Is this a concern?

No, a lambda layer is a stateless resource, and we are replacing it with an upgraded version of kubectl. So, the replacement is expected here.
