Health score?A 0-100 score computed nightly from four factors: maintained (40%: recent commits and steady activity), popular (25%: GitHub stars, log scale), easy to install (20%: platforms, install notes, setup guides, Docker image) and light to run (15%: minimum RAM, ARM support). When the source code has been checked, a fifth factor, security check (20%: automated scan for committed secrets, unsafe desktop-app settings, known-vulnerable dependencies and project hygiene; any serious finding caps it at 20), is added. Factors without data are left out and the rest are rescaled.

Common questions

What network configuration is required for Rebuild-DNDC to manage dependent containers?

Create a Docker network named container:lowercase_master_container_name and attach dependent containers to it, or add --net=container:lowercase_master_container_name to extra parameters. The master container name must be all lower case.

In what order should the VPN, dependent containers, and Rebuild-DNDC start?

Start the VPN/master container first, start the routed containers next, and start Rebuild-DNDC after them. Use a short startup delay so the VPN has time to establish a connection.

How does Rebuild-DNDC handle loss of connectivity from the master container?

Set mastercontconcheck=yes and configure ping_ip or ping_ip_alt targets. The app pings the target ping_count times before restarting the master container if connectivity fails.

Where are Rebuild-DNDC’s configuration files stored?

The example stores its configuration in /config/rebuild-dndc, mapped to /mnt/appdata/rebuild-dndc/config/rebuild-dndc on Unraid. It also needs /var/run/docker.sock read-write and the Docker Man templates-user directory read-only.

How do I install Rebuild-DNDC on Unraid?

Open Community Applications, search for Rebuild-DNDC, and click Install. This installs the app for use from the Unraid server.
