Kubernetes Pod and Container Security

Internal

• Kubernetes Security Concepts

Overview

Containers instantiated from container images and running in pods in a Kubernetes cluster are executing by default with container image configuration - for example, the user and the group various container processes run under are by default specified with the USER directive in the container image -, in non-privileged mode and using a pre-defined set of kernel capabilities. The pod and container security contexts, described below, are a declarative method to modify all these run-time settings and get the containers to run with a different run-time configuration.
