Changing image base from Ublue images to vanilla Silverblue - what is the best approach?
Hi! I have a question, if I wanted to migrate my custom image's base from ublue's
silverblue-main to Fedora's vanilla Silverblue, what would be the best way to do so successfully?
I've tried doing so several times in the past w these steps:
1. Create a custom Silverblue image in my repo with quay.io/fedora/fedora-silverblue as base-image. This creates custom-silverblue-base
2. Builds just fine with the signing module
3. Update my existing result image recipe.yml (let's call this result-image) - base-image is replaced from ghcr.io/ublue-os/silverblue-main to gchr.io/username/custom-silverblue-base
4. result-image builds just fine with the signing module
5. result-image is deployed just fine on the target machine, boots & runs as expected
6. When running rpm-ostree update, it fails giving errors as such:
Some digging around made me think perhaps it has something to do w/ files under /etc/pki/containers and/or /etc/containers/registries.d/, but sudo ostree admin config-diff doesn't show that the files have been modified locally. Also, my cosign keys are unmodified, so this is not like the case of Bluefin's cosign keys from last year.
I wonder if it would be more efficient to just create a new repo altogether?
Would appreciate any input on this!13 replies
