The following changes were made:
The
gitlab-registry.cern.ch/key4hep/k4-deploy/alma9-buildimage is used as base. There are two images generated:mucoll-spack: Contains a spack installation.mucoll-sim: Contains the installation of the Muon Collider software as a spack environment.The images are now based on the spack package distribution system using packages from the key4hep-spack and mucoll-spack repositories. The exact tested commits for each repository and spack itself are specified.
The version of spack is taken from key4hep-spack's
.latest-commitfile. That way we use an externally tested version.Any patches to spack to fix packages broken outside of their control (ie: download links) are applied using a new
apply_patches.shscript for both key4hep-spack and mucoll-spack. This script checks that the corresponding spack version is cloned (via.latest-commit) and runs the.cherry-pickscript.The desired spack environment is named
simand copied from mucoll-spack/tree/release/environments/mucoll-release.The following setup scripts are available. This corresponds to the setup sued for the CERN 2023 tutorial.
/opt/setup_spack.sh: Load Spack only./opt/setup_mucoll.sh: Load the sim environment. Only this one is needed by most end users.
