Canonical has improved security of the latest releases of its Charmed Kubernetes and Microk8s by adding support for containerd.

The momentum continues to be strong for containerd – the industry-standard container runtime. According to Carmine Rimi, product manager for Kubernetes at Canonical, “Enabling Kubernetes to drive containerd directly reduces the number of moving parts, reduces latency in pod startup times, and improves CPU and memory usage on every node in the cluster.”

Canonical promises to continue to support the traditional Docker runtime in its Kubernetes offerings. Clusters will preserve their choice of runtime during upgrades, Canonical added.

“After being accepted into CNCF nearly two years ago, containerd continues to see significant momentum – showcasing the demand for foundational container technologies,” said Chris Aniszczyk,
CTO of the Cloud Native Computing Foundation.

With the multi-cloud Kubernetes operations, compatibility and portability, Canonical supports customers on Amazon EKS, Azure AKS, and Google GKE with Ubuntu worker nodes, and Charmed Kubernetes and MicroK8s for on-premise Kubernetes.
