Issue description

When using incus image export, the metadata.yaml in the tarball might have a wrong creation_date field. For example today (13 november) the images exported (and imported by simplestreams) have a date of the 6th of november…

Steps to reproduce

• Create an image imageX a few days ago
• incus launch imageX container
• edit some stuff in the container
• incus stop container
• incus publish container imageY
• incus image show imageY show the correct creation date (right now)
• incus image export imageY imageY creates imageY.tar.gz with metadata.yaml… THAT CONTAINS imageX's CREATION DATE!

Also, imageY's expiry date is 1 month after imageX's creation, not imageY…

So it looks like the creation_date "leaks" via container launch / publication ?

Information to attach

• Any relevant kernel output (dmesg)
• Container log (incus info NAME --show-log)
• Container configuration (incus config show NAME --expanded)
• Main daemon log (at /var/log/incus/incusd.log)
• Output of the client with --debug
• Output of the daemon with --debug (alternatively output of incus monitor --pretty while reproducing the issue)

@stgraber I just tested your branch and it does not seem to fix the issue. See:

EDIT: I'm sorry I did not understand that export is actually called while publishing an instance, and not when calling incus image export, so I re-ran a container creation, publication and export, and the issue is still present.

(actually I also discovered that I just need to extract metadata.yaml from /var/lib/incus/images/3e6cdf28b6dbd831daadaf034210a3a3499e45470f9d82ea086863ee0dbb51c9, and it's the same (wrong) date)

Also in the debug logs I can see:

time="2024-11-14T13:01:52+01:00" level=info msg="Exporting instance" created="2024-11-14 12:01:01.248950148 +0000 UTC" ephemeral=false instance=pouet instanceType=container project=default used="2024-11-14 12:01:10.4493817 +0000 UTC"
