NAME

       podman-diff - Inspect changes on a container or image's filesystem

SYNOPSIS

       podman diff [options] container|image [container|image]

DESCRIPTION

       Displays changes on a container or image's filesystem.  The container or image is compared
       to its parent layer or the second argument when given.

       The output is prefixed with the following symbols:

       ┌───────┬──────────────────────────────────┐
       │Symbol │ Description                      │
       ├───────┼──────────────────────────────────┤
       │A      │ A file or directory was added.   │
       ├───────┼──────────────────────────────────┤
       │D      │ A file or directory was deleted. │
       ├───────┼──────────────────────────────────┤
       │C      │ A file or directory was changed. │
       └───────┴──────────────────────────────────┘

OPTIONS

   --format
       Alter the output into a different format.  The only valid format for podman diff is json.

   --latest, -l
       Instead of providing the container name or ID, use the last created container.  Note:  the
       last  started  container  can  be  from  other users of Podman on the host machine.  (This
       option is not  available  with  the  remote  Podman  client,  including  Mac  and  Windows
       (excluding WSL2) machines)

EXAMPLE

       Show container-modified files versus the container's image:

       $ podman diff container1
       A /myscript.sh

       Show container-modified files versus the container's image in JSON format:

       $ podman diff --format json myimage
       {
         "changed": [
           "/usr",
           "/usr/local",
           "/usr/local/bin"
         ],
         "added": [
           "/usr/local/bin/docker-entrypoint.sh"
         ]
       }

       Show the difference between the specified container and the image:

       $ podman diff container1 image1
       A /test
