Kubernetes is a container orchestration framework. The Kubernetes architecture has a control plane made up of one or more computers, virtual or real. The control plane acts as an intermediary between the world outside the cluster and the internal cluster. (A cluster is a collection of one or many computers, virtual or real.)In Kubernetes this is done with rolling updates. A rolling update allows a Deployment update to take place with zero downtime. It does this by incrementally replacing the current Pods with new ones. The new Pods are scheduled on Nodes with available resources, and Kubernetes waits for those new Pods to start before removing the old Pods.Sep 3, 2021 · Kubernetes SecurityContext Overview.
