💖 singularity(1) — the manual page, but make it slay 💖

okay bestie, pull up a chair, we're reading the singularity manual together and honestly? it's giving iconic. this is section 1 of the singularity manual, and today's main character is the overlay sync situation. let's get into it 🫶

✨ NAME ✨

singularity-overlay-sync — sync your OCI-SIF manifest & config with your overlay content, no cap 💅

🌸 SYNOPSIS 🌸

singularity overlay sync oci-sif

that's it. that's the whole vibe. three little words and a target 🎀

🦋 DESCRIPTION 🦋

so the overlay sync command does one very specific little thing and it does it well: it updates the OCI manifest and config in an OCI-SIF image, so that they reflect any changes you've made to the content of a writable overlay. 🧚

like, you changed stuff in the overlay? the manifest and config were not aware. they were living in the past. this command drags them into the present. periodt. 🔥

👑 OPTIONS 👑

  • -h, --help[=false] — help for sync. that's the whole option list. she's minimal, she's focused, she's got main character energy. ⭐

🌈 EXAMPLE 🌈

wanna synchronize an OCI-SIF image that's holding an overlay? say less:

To synchronize an OCI-SIF image containing an overlay:
$ singularity overlay sync /tmp/overlay.oci.sif

literally copy, paste, slay. 🍓

heads up bestie: this whole page was auto generated by spf13/cobra, so nobody hand-crafted these words with love. the facts are the facts though — manifest, config, OCI-SIF, writable overlay. don't shoot the messenger 💀

and that's a wrap on the singularity manual, section 1 — written up in Sep 2026, auto generated by spf13/cobra (yes, again, she's everywhere). stay synced, stay iconic, and may your manifest always match your overlay 💖✨🎀🦋🌸💅🫶
