Gotchas and maintenance

Gotchas

Some images use the latest tag or no tag. Images without a pinned version: beszel: henrygd/beszel (no tag). A later pull can get a different version. (github.com/henrygd/beszel/blob/b97abf7/supplemental/docker/hub/docker-compose.yml, checked 2026-10-22)
The compose file publishes host ports. Host ports: 8090 (beszel). A port without a host address listens on all host network interfaces. (github.com/henrygd/beszel/blob/b97abf7/supplemental/docker/hub/docker-compose.yml, checked 2026-10-22)
The compose file mounts host folders. Host paths mounted into containers: ./beszel_data at /beszel_data (beszel). (github.com/henrygd/beszel/blob/b97abf7/supplemental/docker/hub/docker-compose.yml, checked 2026-10-22)
