A container to provide out-of-the-box bridging functionality to a ZeroTier network.
docker build -t zerotierbridge .
docker run --privileged -e ZT_NETWORK=NETWORK_ID_HERE zerotierbridge:latest
Once running, log into your ZeroTier interface and approve the new device. Click the wrench next to the name and select 'Allow Ethernet Bridging.'
You also need to add a static route into ZeroTier so that the traffic is routed correctly. see below
If you need to run this on a device with different architecture (a raspberry pi, for instance), then just edit line 3 of the Dockerfile.
If you were using a Raspberry Pi 4, you would change this to ARCH=arm64 and the container will pull the correct ZeroTier installer.
ARCH=arm64
