v2.0.0

MqDockerUp v2.0.0 🎉

A major release that fixes multi-container / multi-host support and adds a container whitelist. It contains breaking changes to how entities are published to Home Assistant — please read the upgrade notes below before updating.

⚠️ Breaking Changes

MQTT topics and Home Assistant entity identities are now based on the container name instead of the image (#645).

Previously every entity's MQTT topic, unique_id and device identifiers were derived from the container's image. Running several containers from the same image — or the same image across multiple hosts — made them collide and overwrite each other, so only one container showed up in Home Assistant. They are now based on the container name (optionally prefixed via MAIN_PREFIX), so each container gets its own device and entities.

What happens when you upgrade

• On first start, v2.0.0 runs a one-time automatic migration that clears the old image-based discovery topics. Home Assistant removes the stale entities and they are republished under the new container-based names — no manual broker cleanup is needed for the entities.
• Because entity unique_ids change, any automations, scripts, dashboards or history that referenced the old entity IDs must be updated to the new ones.
• Multi-host setups: give each host a unique MAIN_PREFIX so containers with the same name on different hosts stay distinct.

✨ New Features

Container monitor / whitelist (#644). List only the containers you want monitored instead of denylisting everything else:

• MONITOR_CONTAINERS — only these containers are monitored.
• MONITOR_UPDATES — only these containers are checked for updates.
• Per-container labels mqdockerup.monitor_container / mqdockerup.monitor_updates.
• Leave empty (or *) to keep the default of monitoring everything. Existing ignore rules still take precedence.

🔧 Maintenance

• Centralized MQTT topic/identity generation into a new TopicService.
• Migrated the database driver from sqlite3 to better-sqlite3 (same SQLite data file, no data loss) and updated dependencies; npm audit is now clean.
