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 con-
tainer. Note: the last started container can be from other users of
Podman on the host machine. (This option is not available with the re-
mote 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 for-
mat:
$ podman diff --format json myimage
{
"changed": [

"/usr/local",
"/usr/local/bin"
],
"added": [
"/usr/local/bin/docker-entrypoint.sh"
]
}
