Multipass build provider does not support resource settings core core22 snaps

[Justin Cattle]

Hi,

As per the docs, you can set custom resource usage for the Multipass instance using environment variables: https://snapcraft.io/docs/build-providers

$ export SNAPCRAFT_BUILD_ENVIRONMENT_CPU=8
$ export SNAPCRAFT_BUILD_ENVIRONMENT_MEMORY=16G

It's noted in the docs that this is not possible for core22 snaps, which means that it's a breaking change for core22.

Ideally, this still would be supported in some way for core22 snaps.

This was discussed a little here: https://forum.snapcraft.io/t/build-providers/4157/34?u=jocado

Cheers,
Just

Related issue with the envvar SNAPCRAFT_MAX_PARALLEL_BUILD_COUNT: https://github.com/canonical/craft-providers/issues/212

I'm wondering if there should be an interaction between SNAPCRAFT_BUILD_ENVIRONMENT_CPU and SNAPCRAFT_MAX_PARALLEL_BUILD_COUNT. I can't think of a normal scenario where these 2 env vars would be different.

Confirmed that this is not currently supported in core22.

Is this still not working ? Building Firefox with only 2 CPUs is suboptimal.
