# Require `livenessProbe` and `readinessProbe`
|
|
|
|
For each pod, a `livenessProbe` is carried out by the kubelet to determine if containers are running and when to restart the pod. A `readinessProbe` is used by services and deployments to determine if the pod is ready to recieve network traffic.
|
|
|
|
Both liveness and readiness probes need to be configured to manage the pod lifecycle during restarts and upgrades.
