+# NAME
+podman-container-exists- Check if a container exists in local storage
+
+# SYNOPSIS
+**podman container exists**
+[**-h**|**--help**]
+CONTAINER
+
+# DESCRIPTION
+**podman container exists** checks if a container exists in local storage. The **ID** or **Name**
+of the container may be used as input. Podman will return an exit code
+of `0` when the container 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 an container called `webclient` exists in local storage (the container does actually exist).
+```
+$ sudo podman container exists webclient
+$ echo $?
+0
+$
+```
+
+Check if an container called `webbackend` exists in local storage (the container does not actually exist).
+```
+$ sudo podman container exists webbackend
+$ echo $?
+1
+$
