# Deploy with:
#   docker stack deploy -c synapse.yml synapse
#
# Runs on: pve-social
# Matrix homeserver. Client/federation API on port 8008.
#
# First deploy generates /data/homeserver.yaml automatically.
# After first boot, update homeserver.yaml on pve-social to add PostgreSQL:
#   database:
#     name: psycopg2
#     args:
#       user: synapse_user
#       password: <from pass homelab/SYNAPSE_DB_PASSWORD>
#       database: synapse_db
#       host: postgres_postgres
#       cp_min: 5
#       cp_max: 10
