# Gitlab-CI Workflow
# stages:
#   build:
#     - Runs on commits on master or tags that match the pattern "v[0-9]+\.[0-9]+.*$". (e.g. 1.0, v2.1rc1)
#   deploy-staging:
#     - Runs on commits on master or tags that match the pattern v1.0, v2.1rc1 (continues deployment)
#   deploy-production:
#     - Runs on tags that match the pattern v1.0, v2.1rc1 (manual deployment)
