The shared \`intranet\` Docker network has many other containers aliased as \`db\` and \`redis\` (mastodon-db, mailman redis, etc.). Docker's embedded DNS resolved those before our own services, sending the app's MySQL connection to the wrong IP and crashing it in a restart loop. Switched both DATABASE_URL and REDIS_URL in the prod overlay to use the project-prefixed container names (readmarkets-db-1, readmarkets-redis-1), which are globally unique on the Docker daemon. Applied to both app and scheduler. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

# Production overlay. Applied on the VPS with:
|
|
#
|
|
# docker compose -f docker-compose.yml -f docker-compose.prod.yml up -d
|
|
#
|
|
# Drops the host port binding entirely and joins the `intranet` external
|
|
# Docker network so a front-side proxy (Nginx Proxy Manager) on the same
|
|
# network can reach the container directly. The app listens on port 80
|
|
# inside the container so NPM upstreams are uniform across services
|
|
# (always `<container-name>:80`).
|
|
#
|
|
# The local-dev compose (just `docker-compose.yml` alone) still binds to
|
|
# the host port from `.env` / CASSANDRA_PORT — unchanged.
