+
+## NAME
+podman\-pod\-restart - Restart one or more pods
+
+## SYNOPSIS
+**podman pod restart** [*options*] *pod* ...
+
+## DESCRIPTION
+Restart containers in one or more pods. Containers will be stopped if running and then restarted.
+Stopped containers will only be started. You may use pod IDs or names as input.
+The pod ID will be printed upon successful restart.
+When restarting multiple pods, an error from restarting one pod will not effect restarting other pods.
+
+## OPTIONS
+
+**--all, -a**
+
+Restarts all pods
+
+**--latest, -l**
+
+Instead of providing the pod name or ID, restart the last created pod.
+
+## EXAMPLE
+
+podman pod restart mywebserverpod
