spack-deployment-workflow.yml

# Release pipeline:
# 
# This pipeline performs the deployment of a new gchp spack
# package upon the release of a new version
#
# This pipeline is triggered by tagged versions excluding 
# pre-releases. 
#
# Notes:
#   - This workflow requires a personal access token for pushing to the 
#     pr-source-repo. The PAT needs repo + read:org permissions. The PAT
#     needs to be added to the GCHP repo as an action secret 
#     called GH_PUSH_PAT.
