podman-container-diff(1)

NAME

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

SYNOPSIS

podman container diff [options] container [container]

DESCRIPTION

Displays changes on a container's filesystem. The container 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 container 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)

EXAMPLE

    # podman container diff container1
    C /usr
    C /usr/local
    C /usr/local/bin
    A /usr/local/bin/docker-entrypoint.sh

    $ podman container diff --format json container1 container2
    {
         "added": [
              "/test"
         ]
    }
