trails/infrastructure/docker-compose.staging.yml

# Staging / PR-preview compose file.
#
# Used for both the persistent staging stack and ephemeral PR previews.
# The cd-staging.yml workflow picks the project name and fills in the host
# ports + DOMAIN + STAGING_DATABASE from the PR number (or "staging" for the
# persistent stack):
#
#   # Persistent staging
#   PROJECT=trails-staging
#   JOURNAL_HOST_PORT=3100 PLANNER_HOST_PORT=3101 \
#   DOMAIN=staging.trails.cool STAGING_DATABASE=trails_staging \
#   docker compose -f docker-compose.staging.yml -p $PROJECT up -d
#
#   # PR 123 preview (port = 3200 + 2N for journal, 3201 + 2N for planner)
#   PROJECT=trails-pr-123
#   JOURNAL_HOST_PORT=3446 PLANNER_HOST_PORT=3447 \
#   DOMAIN=pr-123.staging.trails.cool STAGING_DATABASE=trails_pr_123 \
#   JOURNAL_IMAGE_TAG=pr-123 PLANNER_IMAGE_TAG=pr-123 \
#   docker compose -f docker-compose.staging.yml -p $PROJECT up -d
#
# `trails-shared` is created by the production compose file (see
# docker-compose.yml) so staging/preview containers can reach the production
# `postgres` host. BRouter lives on a separate host and is reached over
# vSwitch using the production-shared BROUTER_URL / BROUTER_AUTH_TOKEN.
#
# Container names are not pinned — Docker Compose generates them from the
# project name (e.g. `trails-pr-123-journal-1`), which keeps each preview
# isolated without manual naming.
