podman-diff(1)

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 will be 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. If you use methods other than Podman to run containers such as CRI-O, the last started container could be from either of those methods. (This option is not available with the remote Podman client, including Mac and Windows (excluding WSL2) machines)

EXAMPLE

    $ podman diff container1
    A /myscript.sh

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

    $ podman diff container1 image1
    A /test
