✨ podman-image-diff(1) ✨

okay bestie, welcome to the podman-image-diff page from the General Commands Manual 💖 this one's all about peeking at what changed inside an image's filesystem, and honestly? it's giving detective energy 🔍

🌸 NAME 🌸

podman-image-diff — inspect changes on an image's filesystem 🦋

---

💅 SYNOPSIS 💅

podman image diff [options] image [image]

---

✨ DESCRIPTION ✨

So basically, this command displays changes on an image's filesystem. The image gets compared to its parent layer, OR to the second argument if you hand it one. Two images in, one little diff story out 🎀

The output is prefixed with these symbols, and you're gonna want to know them by heart:

• 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 image diff is json. that's it, that's the whole menu, no cap 🍓

---

🔥 EXAMPLES 🔥

Display image differences from images parent layer:

$ podman image diff redis:old
C /usr
C /usr/local
C /usr/local/bin
A /usr/local/bin/docker-entrypoint.sh

Display image differences between two different images in JSON format:

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