podman-image-diff - Inspect changes on an image's filesystem
podman image diff [options] image [image]
Displays changes on an image's filesystem. The 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. |
Alter the output into a different format. The only valid format for podman image diff is json.
$ podman diff redis:old C /usr C /usr/local C /usr/local/bin A /usr/local/bin/docker-entrypoint.sh
$ podman diff --format json redis:old redis:alpine { "changed": [ "/usr", "/usr/local", "/usr/local/bin" ], "added": [ "/usr/local/bin/docker-entrypoint.sh" ] }
