Kubernetes Repo Changes

The Kubernetes community has changed to community-owned package repositories. Learn how to update your SLATE Clusters in this blog.

What Changed?

• Kubernetes Legacy Package Repositories Will Be Frozen On September 13, 2023
• pkgs.k8s.io: Introducing Kubernetes Community-Owned Package Repositories

How does this affect us as SLATE Administrators?

The amount of work to change over to the new package repositories is relatively small.

1. SSH to your SLATE Cluster master node and switch to the root user.

2. Execute the following to update the package repository file for Kubernetes 1.24.x.

   export KUBE_VERSION=1.24 && \
   cat <<EOF | tee /etc/yum.repos.d/kubernetes.repo
   [kubernetes]
   name=Kubernetes
   baseurl=https://pkgs.k8s.io/core:/stable:/v${KUBE_VERSION}/rpm/
   enabled=1
   gpgcheck=1
   gpgkey=https://pkgs.k8s.io/core:/stable:/v${KUBE_VERSION}/rpm/repodata/repomd.xml.key
   EOF
   

3. Verify the changes by executing:

   yum list kubectl
   

   If the results include versions other than 1.24.x, remove cached Yum packages and headers:

   yum clean all
   

   and check again.

4. Close the connection and repeat the previous steps on each of your SLATE Cluster worker nodes.

5. Continue to update patch versions of the various Kubernetes 1.24.x packages normally through commands like yum update ... or dnf update ....
