Readiness Probe

A Kubernetes check that determines whether a pod can receive traffic; failing pods are removed from Service endpoints.

Definition

Readiness probes protect users during startup, dependency outages, or overload without restarting the container. Rolling updates wait for new pods to be ready.

Example

readinessProbe: httpGet: {path: /ready, port: 8080}

Exam tip

Readiness does not restart containers.
