BOOTC-CONTAINER-INSPECT(8)

🎀 BOOTC-CONTAINER-INSPECT 🎀

okay bestie, so this is a page from the System Manager's Manual — it's the bootc-container-inspect(8) girlie, and she's here to spill the whole container image metadata situation directly into your stdout. ✨

---

💖 NAME 💖

bootc-container-inspect — spits out JSON to stdout with all the container image metadata inside. that's the whole job. and she ate. 💅

---

🌸 SYNOPSIS 🌸

bootc container inspect

---

🦋 DESCRIPTION 🦋

Output JSON to stdout containing the container image metadata.

that's it. that's the vibe. she looks at the container image, she tells you what's in it, in JSON, on stdout. main character energy only. 👑

---

✨ OUTPUT ✨

so what you get back is a JSON object, and it's got these fields, periodt:

• kargs — an array of the kernel arguments that are embedded right there in the container image. 🧚
• kernel — an object with kernel info in it, OR null if no kernel was found at all (yes, she can just hand you a null, no cap):
  • version — the kernel version identifier. for vmlinuz kernels this is derived from the /usr/lib/modules/<version> directory name (equivalent to uname -r, iykyk). for UKI images, this is the UKI filename minus the .efi extension — which should usually be the same as the uname. 🌈
  • unified — a boolean telling you whether the kernel is packaged as a UKI (Unified Kernel Image). ⭐

---

💅 OPTIONS 💅

• --rootfs=ROOTFS — operate on the rootfs you hand over, bestie.

Default: /

• --json — output it in JSON format. 📋
• --format=FORMAT — what format the output should be in.

Possible values:

• humanreadable
• yaml
• json

🌈 EXAMPLES 🌈

wanna inspect the container image metadata? say less:

bootc container inspect

Example output when it's a vmlinuz kernel:

{
  "kargs": [
    "console=ttyS0",
    "quiet"
  ],
  "kernel": {
    "version": "6.12.0-0.rc6.51.fc42.x86_64",
    "unified": false
  }
}

Example output when it's a UKI:

{
  "kargs": [],
  "kernel": {
    "version": "7e11ac46e3e022053e7226a20104ac656bf72d1a",
    "unified": true
  }
}
