# ZeroTierBridge
|
|
|
|
A container to provide out-of-the-box bridging functionality to a ZeroTier network.
|
|
|
|
## Running
|
|
|
|
### Prerequisites
|
|
|
|
- Docker running as your logged in user (if `docker ps` runs then you're good, if not follow the link ->) - [Linux instructions here](https://docs.docker.com/engine/install/linux-postinstall/)
|
|
|
|
### ZeroTier UI Changes
|
|
|
|
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. Add this a bit larger than normal because of [longest prefix matching](https://en.wikipedia.org/wiki/Longest_prefix_match).
|
|
|
|
|
|
|
|
### Docker Compose
|
|
|
|
**You need to edit the `ZT_NETWORKS` and `ARCH` variable in the `docker-compose.yml` file first to add your networks and make sure your acrhitecture is correct (see [this page](http://download.zerotier.com/debian/buster/pool/main/z/zerotier-one/) for examples, usually either amd64 or arm64)**
|
|
|
|
Easiest way to bring up is via Docker Compose. Rename `docker-compose.yml.example` to `docker-compose.yml` and run `docker compose up -d`.
|
|
|
|
If you want to disable bridging, set `ZT_BRIDGE=false`. This can be done after the initial networks have been joined (just change the environment variable in the `docker-compose.yml` file and run `), as the ZeroTier config persists but IPTables forwarding is done on each container startup.
|
|
|
|
### OG Docker
|
|
|
|
`docker build -t zerotierbridge .`
|
|
|
|
`docker run --privileged -e ZT_NETWORKS=NETWORK_1 NETWORK_2 -e ZT_BRIDGE=true zerotierbridge:latest`
|
|
|
|
Add your network ID(s) into the `ZT_NETWORKS` argument, space separated.
|
|
|
|
Disable bridging by passing `ZT_BRIDGE=false`. This can be done after the initial networks have been joined (just rebuild the container), as the ZeroTier config persists but IPTables forwarding is done on each container startup.
|
|
|
|
#### Persistent Storage
|
|
|
|
If you would like the container to retain the same ZeroTier client ID on reboot, attach a volume as per the below.
|
|
|
|
`docker run --privileged -e ZT_NETWORKS=NETWORK_ID_HERE ZT_BRIDGE=true -v zt_config:/var/lib/zerotier-one/ zerotierbridge:latest`
|
|
|
|
#### Caveat: Architecture
|
|
|
|
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.
