podman-diff - Man Page

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.

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"
  ]
}
