philbarker79/tetherd repository overview

⁠Tetherd

Keeps containers attached to the network of the container they route through.

If you run apps through a VPN sidecar with --network container:gluetun, those apps lose their networking whenever the VPN container restarts or is recreated. Tetherd watches for that and repairs it — preferring a plain restart, and only rebuilding a container when it genuinely has to.

This is a clean-room successor to Rebuild-DNDC⁠. It is not a fork. It reads configuration from the live Docker API, not from Unraid XML templates.

Unraid: install from Community Applications (search Tetherd) once the template is listed. Until then, add the XML from Phil-Barker/unraid-templates⁠.

The image talks to the host Docker socket and runs as root for the same reason Watchtower does: that socket is typically root:docker mode 660.
