- Run cache:warmup in the build stage so containers start with a
pre-built Symfony kernel and DI container
- Scope the cache volume to var/cache/prod/pools where Symfony writes
pool data, preserving the warmed kernel across container restarts
- Add docker-compose.prod.yml for deploying the registry image without
the dev override being picked up automatically
- Expand .dockerignore to exclude vendor/, tests/, docs, compose files,
and env files from the build context
