Imagine you're deploying an app in Kubernetes, and you want to ensure it doesn't misbehave or get exploited. Just like you lock your front door at night, Kubernetes gives you a way to lock down containers using something called a Security Context. Security Context lets you define security-related settings—like user IDs, privilege levels, filesystem permissions—for your pods and containers. It's like giving each pod a security badge that says: “Here’s what I can and can’t do.”
