# deploy/portainer/federated-test.stack.yml
#
# Portainer / Docker Swarm stack template — federated-tier test instance
#
# PURPOSE
#   Deploys a single federated-tier Mosaic gateway with co-located Postgres
#   (pgvector) and Valkey for end-to-end federation testing. Intended for
#   mos-test-1.woltje.com and mos-test-2.woltje.com (DEPLOY-03/04).
#
# REQUIRED ENV VARS (set per-stack in Portainer → Stacks → Environment variables)
#   STACK_NAME          Unique name for Traefik router/service labels.
#                       Examples: mos-test-1, mos-test-2
#   HOST_FQDN           Fully-qualified domain name served by this stack.
#                       Examples: mos-test-1.woltje.com, mos-test-2.woltje.com
#   POSTGRES_PASSWORD   Database password — set per stack; do NOT commit a default.
#   BETTER_AUTH_SECRET  Random 32-char string for BetterAuth session signing.
#                       Generate: openssl rand -base64 32
#   BETTER_AUTH_URL     Public gateway base URL, e.g. https://mos-test-1.woltje.com
#
# OPTIONAL ENV VARS (uncomment and set in Portainer to enable features)
#   ANTHROPIC_API_KEY   sk-ant-...
#   OPENAI_API_KEY      sk-...
#   OTEL_EXPORTER_OTLP_ENDPOINT  http://<collector>:4318
#   OTEL_SERVICE_NAME   (default: mosaic-gateway)
#
# REQUIRED EXTERNAL RESOURCES
#   traefik-public      Docker overlay network — must exist before deploying.
#                       Create: docker network create --driver overlay --attachable traefik-public
#   letsencrypt         Traefik cert resolver configured on the Swarm manager.
#   DNS A record        ${HOST_FQDN} → Swarm ingress IP (or Cloudflare proxy).
#
# IMAGE
#   Pinned to digest fed-v0.1.0-m1 (DEPLOY-01 verified).
#   Update digest here when promoting a new build.
#
# NOTE: This is a TEST template — production deployments use a separate
#       parameterised template with stricter resource limits and secrets.
