NAME

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

SYNOPSIS

podman diff [options] name

podman container diff [options] name

DESCRIPTION

Displays changes on a container or image's filesystem. The container or image will be compared to its parent layer

OPTIONS

--format

Alter the output into a different format. The only valid format for 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.

The latest option is not supported on the remote client.

EXAMPLE

# podman diff redis:alpine
C /usr
C /usr/local
C /usr/local/bin
A /usr/local/bin/docker-entrypoint.sh

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