## SYNOPSIS
**podman inspect** [*options*] *name* [...]
-**podman image inspect** [*options*] *image*
-
-**podman container inspect** [*options*] *container*
-
## DESCRIPTION
+
This displays the low-level information on containers and images identified by name or ID. By default, this will render
all results in a JSON array. If the container and image have the same name, this will return container JSON for
unspecified type. If a format is specified, the given template will be executed for each result.
+For more inspection options, see:
+
+ podman container inspect
+ podman image inspect
+ podman network inspect
+ podman pod inspect
+ podman volume inspect
