Install Docker

On Raspberry Pi:

Install Docker:
```
curl -sSL https://get.docker.com | sh
```
If you want to use Docker as non-root, without requiring sudo before each command, modify your user settings. Sign out for the changes to take effect:
```
sudo usermod -aG docker $USER
```
Start Docker if it is not already running:
```
sudo dockerd
```

Enable IP forwarding

Linux typically disables IP forwarding by default. Run the setup-host script to enable IP forwarding on the host system.

curl -sSL
https://raw.githubusercontent.com/openthread/ot-br-posix/refs/heads/main/etc/docker/border-router/setup-host | bash

Get the OTBR Docker image

Get the OTBR Docker image by pulling it directly from the OpenThread Docker Hub, or by cloning the OTBR repository and building the included Dockerfile locally.

Pull the image from Docker Hub

Pull the image:

docker pull openthread/border-router:latest

It should now appear in your list of Docker images:

docker images
REPOSITORY                 TAG       IMAGE ID       CREATED       SIZE
openthread/border-router   latest    08666d77013d   2 hours ago   132MB

Build the Dockerfile

To create the image yourself, clone the OpenThread Border Router repository and build the included Dockerfile.

Install git:
```
sudo apt install git
```

Clone the OTBR repository:

git clone --depth=1 https://github.com/openthread/ot-br-posix
cd ot-br-posix

Build the Dockerfile:

docker build --no-cache -t openthread/border-router -f etc/docker/border-router/Dockerfile .

Create an OTBR configuration file

Create a otbr-env.list file to store OTBR Docker configurations.

OT_RCP_DEVICE=spinel+hdlc+uart:///dev/ttyACM0?uart-baudrate=1000000
OT_INFRA_IF=wlan0
OT_THREAD_IF=wpan0
OT_LOG_LEVEL=7

OT_RCP_DEVICE: Specifies the connection to the Thread Radio Co-Processor (RCP).
OT_INFRA_IF: The network interface used for the adjacent infrastructure network (typically Wi-Fi or Ethernet).
OT_THREAD_IF: The network interface name used for the Thread network.
OT_LOG_LEVEL: The verbosity level of logs generated by OpenThread.

Start the OTBR Docker container

Create and run a new container from the OTBR image.

docker run --name=otbr --detach --network=host --cap-add=NET_ADMIN --device=/dev/ttyACM0 --device=/dev/net/tun --volume=/var/lib/otbr:/data --env-file=otbr-env.list --restart=always openthread/border-router

docker run: The base command for running a Docker container.
--name=otbr: Assigns the name "otbr" to the running container. This makes it easier to refer to the container later for actions like stopping, starting, or inspecting it.
--detach: Runs the container in detached mode, meaning it runs in the background and doesn't attach the terminal to the container's standard input, output, or error streams.
--network=host: Makes the container use the host machine's network stack directly. This is often necessary for OTBR, as it needs to have direct access to network interfaces.
--cap-add=NET_ADMIN: Grants the container the NET_ADMIN capability. This is necessary for the container to perform network administration tasks, such as configuring network interfaces and routing.
--device=/dev/ttyACM0: Maps the host's /dev/ttyACM0 device into the container. This is typically the serial port connected to the Thread Radio Co-Processor (RCP). The specific device name (ttyACM0) might vary depending on your system.
--device=/dev/net/tun: Maps the host's /dev/net/tun device into the container. This is necessary for creating and using virtual network interfaces, which are used by OTBR.
--volume=/var/lib/otbr:/data: Mounts the host directory /var/lib/otbr into the container at /data. This allows the container to persist data, such as network configuration, even when the container is stopped or restarted.
--env-file=otbr-env.list: Reads environment variables from the specified file and sets them within the container. These environment variables are likely configuration parameters for the OTBR.
--restart=always: Configures the Docker daemon to automatically restart the container if it stops. This ensures that the OTBR is always running. openthread/border-router: This specifies the Docker image to use for the container. In this case, it's the official OpenThread Border Router image.

View Docker logs

Use the following command on the host to view logs:

docker logs otbr

If OTBR is running successfully, you should have output similar to this:
