Infra Update v8: spack v1 Support

Important

This PR is a major update to the deployment infrastructure. See below for the prerequisites for this repository to be able to merge this PR.

Important

This major version change marks the end of major infrastructure updates for deployments to spack < 1.0.
If you want to deploy to instances of spack < 1.0, you must use build-cd < v8.
If you want to deploy to instances of spack >= 1.0, you must use build-cd >= v8.

Background

We are moving on up to spack v1! This update to spack contains many bug fixes, optimisations and new features that can be incorporated into build-cd.

This update also contains changes that make spack v0.X incompatible with this build-cd v8 update - the most prominent one being the splitting of spacks core codebase from it's builtin spack-packages repo. This means that for provenance, one to keep track of both builtin spack-packages and our own, renamed access-spack-packages. build-cd will centrally control the version of builtin spack-packages for a given instance, and config/versions.jsons spack-packages key is renamed to access-spack-packages.

As noted earlier, this major version of build-cd can only support spack v1, due to spack v1-specific commands in the infrastructure. If you still want to deploy to spack v0.X, you will need to change build-cd to v7, and update the config/versions.json file/spack.yaml.

Features

• Support for spack v1: We're moving to a new, non-beta version of spack! It contains bug fixes, features and optimisations over the old version.

Prerequisites for Merging

• Update build-cd entrypoints (this PR!)
• Update config/versions.json with new inputs (also this PR!)
• Validate compiler additions to the spack manifest (this PR, too!)
• Test and Verify Model built with spack v1

🚀 Attempted to deploy esmf Prerelease pr19-2 with commit d18bdc3

🖥️ Gadi Deployment ✔️

Usage Instructions

esmf, defined in esmf/spack.yaml, will be deployed to Gadi as:

• v8.7.0 as a Release (when merged).
• pr19-2 as a Prerelease (during this PR).

This Prerelease is accessible on Gadi using:

module use /g/data/vk83/prerelease/modules
module load esmf/pr19-2

When using the above modules, the binaries shall be on your $PATH.

For advanced users, this Prerelease is also accessible on Gadi via /g/data/vk83/prerelease/apps/spack/1.1/spack in the esmf-pr19-2 environment.
Due to inode-saving measures, one will have to manually untar the environment metadata before environment activation with tar -xf .spack-env .spack-env.tar. It will require one to have write privileges.

Configuration Information

This Prerelease is deployed using:

• access-nri/spack on branch 1.1
• spack/spack-packages version 8ed34337e15d759890b68682d704aa55dd243537
• access-nri/access-spack-packages version 2026.02.002
• access-nri/spack-config version 2026.02.001

If the above was not what was expected, commit changes to config/versions.json in this PR, or propose changes to build-cds config/settings.json.

FYI, babeltrace2 was added to the upstream spack-packages: https://github.com/spack/spack-packages/blob/develop/repos/spack_repo/builtin/packages/babeltrace2/package.py
