# Require `livenessProbe` and `readinessProbe`

Liveness and readiness probes need to be configured to correctly manage a pods lifecycle during deployments, restarts, and upgrades.

For each pod, a periodic `livenessProbe` is performed by the kubelet to determine if the pod's containers are running or need to be restarted. A `readinessProbe` is used by services and deployments to determine if the pod is ready to recieve network traffic.
