+# NAME
+podman-pod-exists- Check if a pod exists in local storage
+
+# SYNOPSIS
+**podman pod exists**
+[**-h**|**--help**]
+POD
+
+# DESCRIPTION
+**podman pod exists** checks if a pod exists in local storage. The **ID** or **Name**
+of the pod may be used as input. Podman will return an exit code
+of `0` when the pod is found. A `1` will be returned otherwise. An exit code of `125` indicates there
+was an issue accessing the local storage.
+
+## Examples ##
+
+Check if a pod called `web` exists in local storage (the pod does actually exist).
+```
+$ sudo podman pod exists web
+$ echo $?
+0
+$
+```
+
+Check if a pod called `backend` exists in local storage (the pod does not actually exist).
+```
+$ sudo podman pod exists backend
+$ echo $?
+1
+$
+```
