Add kubernetes-1.28 package and variants #3329

etungsten · 2023-08-04T22:39:53Z

Issue number:

Resolves #3274

Description of changes:
This adds the package for K8s 1.28 for building kubelet and new 1.28 Bottlerocket variants.

The new variants will use 6.1 kernel, include secure boot, and use XFS for the data volume filesystem.

Testing done:

Added aws-k8s-1.28 to a 1.27 EKS cluster:

$ k get nodes
NAME                                           STATUS   ROLES    AGE    VERSION
ip-192-168-4-253.us-east-2.compute.internal    Ready    <none>   4m7s   v1.28.0-rc.0-eks-506ffcd
ip-192-168-41-249.us-east-2.compute.internal   Ready    <none>   4m6s   v1.28.0-rc.0-eks-506ffcd

Attempted to deploy pod with image hosted in private registry of a different account:

$ k get pod
NAME     READY   STATUS         RESTARTS   AGE
brtest   0/1     ErrImagePull   0          4s

Applied credential-provider settings:

apiclient apply <<EOF
[settings.kubernetes.credential-providers.ecr-credential-provider]
enabled = true
cache-duration = "30m"
image-patterns = [
  "*.dkr.ecr.us-east-2.amazonaws.com",
  "*.dkr.ecr.us-west-2.amazonaws.com"
]

[settings.aws]
profile = "ecr"
config = “W3...o=”
EOF

Checked kubelet status and logs and verified image able to be pulled and run:

$ k get pod
NAME     READY   STATUS    RESTARTS   AGE
brtest   1/1     Running   0          23m

Ran sonobuoy run --mode=certified-conformance --wait and verified tests passed:

15:34:34             e2e                                         global   complete   passed   Passed:378, Failed:  0, Remaining:  0
15:34:34    systemd-logs    ip-192-168-4-253.us-east-2.compute.internal   complete   passed

jpculp · 2023-08-09T23:40:43Z

We'll probably want to add seccomp-default to kubelet-config if #3334 merges first.

bcressey · 2023-08-14T17:55:40Z

Will need to rebase on the changes in #3259 also which changes the 76-oci-defaults-capabilities.toml symlink.

This adds the K8s 1.28 package.

Everything looks good. Not much has changed since my last test, but built and added node to a 1.27 cluster.

Starting with K8s 1.28, the supported skew between the node and control plane componenets expands by one minor version from n-2 to n-3. See https://kubernetes.io/blog/2023/08/15/kubernetes-v1-28-release/#changes-to-supported-skew-between-control-plane-and-node-versions

etungsten · 2023-08-29T22:04:29Z

EKS-D is planning to do another release for 1.28.1 sometime tomorrow(?) but there are no kubelet changes and the only change is a windows CVE fix. I'll grab the update if it's available and if this doesn't merge by tomorrow.

etungsten · 2023-08-29T23:08:57Z

If we update to the next EKS-D release, we can drop the 0001-Make-gomaxprocs-install-optional-limit-to-tests.patch patch since it's included in 1.28.1: kubernetes/kubernetes@cce3f6f

It looks like the RotateKubeletServerCertificate feature gate was dropped - is this on by default in 1.28?

stmcginnis · 2023-08-30T17:00:01Z

It looks like the RotateKubeletServerCertificate feature gate was dropped - is this on by default in 1.28?

Yeah, this was actually enabled by default since K8s 1.12 (!), but I think it's good to only make the change for the new variant.

bcressey · 2023-08-30T18:15:03Z

Yeah, this was actually enabled by default since K8s 1.12 (!), but I think it's good to only make the change for the new variant.

Is there any output that can be used to confirm that the feature gate is still enabled?

There apparently is no way to query kubelet at runtime to see what feature gates are enabled/disabled.
We can however check the feature gate defaults in k8s source: https://github.com/kubernetes/kubernetes/blob/v1.28.0/pkg/features/kube_features.go#L1136
