# docker-compose.gcp.yml
#
# Use this instead of docker-compose.yml when running on Google Cloud.
# Vault is removed. KMS is handled by GCP Cloud KMS.
#
# Required env vars (set in .env or your CI/CD secret manager):
#
#   GCP_KMS_KEY_NAME — full resource name of the key version
#
# Authentication — pick one, no file mounts required:
#
#   Option A: Inline credentials (running outside GCP)
#     Set GOOGLE_APPLICATION_CREDENTIALS_JSON to the full contents of your
#     service account key JSON. Paste the JSON as a single-line string or
#     use your secret manager to inject it.
#
#   Option B: Workload Identity (GKE, Cloud Run, GCE)
#     Attach a service account to your compute resource.
#     Leave both credential env vars unset — the SDK finds them automatically.
#
# Usage:
#   docker compose -f docker-compose.gcp.yml up
