package only available for one arch

[gfrankliu]

Use this example https://github.com/bazel-contrib/rules_distroless/blob/main/examples/debian_snapshot/bullseye.yaml

If one of the packages is only available for amd64, when running lock, it will complain the said package is not available for arm64. How can I write the yaml file to tell this package is only for amd64?

For example, I need to include package "intel-media-va-driver" that is only available to amd64. Now I can't generate the lock file because this package is not available for arm64.

ok, I added a patch so we can specify arch for a package, so that the package is only included for the specified arch, eg:

archs:
  - "amd64"
  - "arm64"

packages:
  - "ncurses-base"
  - "libncurses6"
  - "tzdata"
  - "coreutils"
  - "dpkg"
  - "apt"
  - "perl"
  - "ca-certificates"
  - "nvidia-kernel-common"
  - "bash"
  - "nginx-full"
  - "nginx-core"
  - "google-cloud-cli"
  - "intel-media-va-driver-non-free/amd64"
 

So all packages are for both amd64 and arm64, except the last "intel-media-va-driver-non-free" which is only for amd64.

Here is the patch:

You can just use a second yaml file to pull in amd64 only deps.

FWIW, #183 will fix this.
