WebAssembly is now used in browsers, Node.js, Deno,...

How to Secure Your Kubernetes Cluster with OpenID Connect and RBAC

A Kubernetes (k8s) cluster comprises worker machines called nodes and a control plane consisting of the API server, scheduler, etcd, controller manager, and in the case of a PaaS (platform as a service), the cloud controller manager. The containers deployed to the cluster run in pods on the worker nodes. At the same time, the control plane takes care of scheduling, responding to requests, and managing the cluster. When you communicate with a Kubernetes cluster,...
