podman-diff(1) General Commands Manual 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
