Kubernetes 1.27

Important Change

Support for Juju 3.1

With this release, Charmed Kubernetes can be deployed with a juju 2.9, 3.0 or 3.1 controller. This release is intended to serve as a migration point away from juju 2.9 deployments which is why we offer a tested strategy of our charms on both 2.9 and 3.1 releases.

Cilium CNI

We are excited to announce the inclusion of Cilium in our portfolio of Container Network Interface solutions for Charmed Kubernetes. Cilium is a powerful CNI, network security and observability solution which provides enhanced performance and improved security for containerised applications. The current version of Cilium shipped within the charm is 1.12.5. It also comes bundled with Hubble: a networking and security observability solution that offers real time insights of the network and the security state of the cluster with little performance impact.

Cloud Providers and Cloud Storage

Operator charms for external cloud providers have been expanded and now include AWS, Azure, GCP, and vSphere. Previously, cloud-specific features such as load balancing and storage were managed by Kubernetes in-tree solutions. Today, cloud provider charms offer flexible management of these features decoupled from any specific Kubernetes release.

NVIDIA Network Operator

The NVIDIA network operator charm is a new addition to the Charmed Kubernetes ecosystem. It simplifies the deployment, operation, and management of NVIDIA networking resources for Kubernetes.
