Building x86_64-v2 instead of x86_64-v3

Hi all, hi @Luke Skywunker ! For my https://eu-os.eu project, I switched to AlmaLinux packages. They build by default for arch = amd64v3. On old hardware (think of schools), this does not run anylonger. Also not on my Thinkpad x220 test device. A PR is open to build the bootc image for amd64v2 as well. https://github.com/AlmaLinux/atomic-desktop/pull/38 It seems to me that bluebuild does not expose the --arch flag from podman, so I do not see how I could force bluebuild to pick one x86_64 over the other (unless I build on a device with only v2 support). Closest issue so far is https://github.com/blue-build/cli/issues/340 on multi-arch. For the time being, one specific arch would be good for me.

For example as in this upstream: being able to publish multiarch images, something like: image-version: 41 default-arch: amd64 arch: amd64,aarch64

Almalinux now has a v2 variant:

podman manifest inspect quay.io/almalinuxorg/atomic-desktop-kde | jq .manifests[].platform
{
  "architecture": "amd64",
  "os": "linux"
}
{
  "architecture": "amd64",
  "os": "linux",
  "variant": "v2"
}

podman manifest inspect quay.io/almalinuxorg/atomic-desktop-kde | jq .manifests[].platform
{
  "architecture": "amd64",
  "os": "linux"
}
{
  "architecture": "amd64",
  "os": "linux",
  "variant": "v2"
}

Things I tried:

bluebuild build --platform linux/amd64/v2 recipes/recipe.yml 
error: invalid value 'linux/amd64/v2' for '--platform <PLATFORM>'
  [possible values: native, linux/amd64, linux/arm64]

  tip: a similar value exists: 'linux/amd64'

bluebuild build --platform linux/amd64/v2 recipes/recipe.yml 
error: invalid value 'linux/amd64/v2' for '--platform <PLATFORM>'
  [possible values: native, linux/amd64, linux/arm64]

  tip: a similar value exists: 'linux/amd64'

In recipe.yml: base-image: --variant=v2 quay.io/almalinuxorg/atomic-desktop-kde

bluebuild build --platform linux/amd64 recipes/recipe.yml
INFO  => Recipe recipes/recipe.yml is valid
INFO  => Templating for recipe at recipes/recipe.yml
ERROR => Failed:

bluebuild build --platform linux/amd64 recipes/recipe.yml
INFO  => Recipe recipes/recipe.yml is valid

I also tried to set the sha256, but this did not work either.

base-image: quay.io/almalinuxorg/atomic-desktop-kde # alternative: quay.io/fedora/fedora-kinoite
image-version: sha256:eea5219ade655f98c5c956497dd8a9a9e4096cb8dd0188b1dca38933cdc05fbc # latest is also supported if you want new updates ASAP

Gives same error as above.

I'll have to add this in as a platform

Got a change to add more platforms https://github.com/blue-build/cli/pull/501

@Luke Skywunker Is selecting a particular image by sha256 already supported?

Luke Skywunker•2mo ago

Yeah, it just requires the right syntax I put that in the issue
