# ============================================================================
# Semaphore configuration-as-code
# ============================================================================
# Drives a freshly-deployed Semaphore instance into its desired state via
# the Semaphore REST API. Idempotent: every object is checked first; only
# missing ones are created. Existing objects are left alone.
#
# Loaded from group_vars/all/semaphore.yml so that the configuration is
# version-controlled in the homelab repo and survives a wipe-and-redeploy
# of the Semaphore VM.

#   semaphore_config:
#     project:        single dict — the lab uses one project ("mk-labs")
#     keys:           list of credentials Semaphore stores
#     repositories:   git repos Semaphore can clone
#     inventories:    Ansible inventories from those repos
#     environments:   env-var bundles
#     templates:      task templates that tie everything together
#
# Each list element has a unique "name" used as the natural identity key.
