- Add pull_policy: always
- Add logging: *default-logging
- Add network block (gitea / external: false)
- Switch environment from list to map format
- Add CONTAINER_NAME to environment
- Use HOSTNAME: ${BASE_HOST_NAME:-...} pattern
- Switch volumes from absolute paths to ./volumes relative paths
- Bind ports to 172.17.0.1 (not 0.0.0.0)
