Instala Docker

En Raspberry Pi:

Instala Docker:
```
curl -sSL https://get.docker.com | sh
```
Si quieres usar Docker como usuario no raíz, sin requerir sudo antes de cada comando, modifica la configuración del usuario. Sal para que se apliquen los cambios:
```
sudo usermod -aG docker $USER
```
Inicia Docker si aún no se está ejecutando:
```
sudo dockerd
```

Habilita el reenvío de IP

Por lo general, Linux inhabilita el reenvío de IP de forma predeterminada. Ejecuta la secuencia de comandos setup-host para habilitar el reenvío de IP en el sistema host.

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

Obtén la imagen de Docker de OTBR

Para obtener la imagen de Docker de OTBR, extrae la imagen directamente del OpenThread Docker Hub o clona el repositorio de OTBR y compila el Dockerfile incluido de forma local.

Extrae la imagen de Docker Hub

Extrae la imagen:

docker pull openthread/border-router:latest

Ahora debería aparecer en tu lista de imágenes de Docker:

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

Compila el Dockerfile

Para crear la imagen por tu cuenta, clona el repositorio de OpenThread Border Router y compila el Dockerfile incluido.

Instala git:
```
sudo apt install git
```

Clona el repositorio de OTBR:

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

Compila el Dockerfile:

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

Crea un archivo de configuración de OTBR

Crea un archivo otbr-env.list para almacenar las configuraciones de Docker de OTBR.

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: Especifica la conexión al coprocesador de radio de Thread (RCP).
OT_INFRA_IF: Es la interfaz de red que se usa para la red de infraestructura adyacente (por lo general, Wi-Fi o Ethernet).
OT_THREAD_IF: Es el nombre de la interfaz de red que se usa para la red Thread.
OT_LOG_LEVEL: Es el nivel de verbosidad de los registros que genera OpenThread.

Inicia el contenedor de Docker de OTBR

Crea y ejecuta un contenedor nuevo a partir de la imagen de OTBR.

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: Es el comando base para ejecutar un contenedor de Docker.
--name=otbr: Asigna el nombre "otbr" al contenedor en ejecución. Esto facilita la referencia al contenedor más adelante para acciones como detenerlo, iniciarlo o inspeccionarlo.
--detach: Ejecuta el contenedor en modo desconectado, lo que significa que se ejecuta en segundo plano y no conecta la terminal a las entradas, salidas o flujos de errores estándar del contenedor.
--network=host: Hace que el contenedor use directamente la pila de red de la máquina anfitrión. Esto suele ser necesario para la OTBR, ya que necesita tener acceso directo a las interfaces de red.
--cap-add=NET_ADMIN: Otorga al contenedor la capability NET_ADMIN. Esto es necesario para que el contenedor realice tareas de administración de redes, como configurar interfaces de red y enrutamiento.
--device=/dev/ttyACM0: Asigna el dispositivo /dev/ttyACM0 del host al contenedor. Por lo general, es el puerto en serie conectado al coprocesador de radio de Thread (RCP). El nombre específico del dispositivo (ttyACM0) puede variar según el sistema.
--device=/dev/net/tun: Asigna el dispositivo /dev/net/tun del host al contenedor. Esto es necesario para crear y usar interfaces de red virtuales, que usa OTBR.
--volume=/var/lib/otbr:/data: Activa el directorio del host /var/lib/otbr en el contenedor en /data. Esto permite que el contenedor conserve datos, como la configuración de red, incluso cuando se detiene o reinicia.
--env-file=otbr-env.list: Lee las variables de entorno del archivo especificado y las establece dentro del contenedor. Es probable que estas variables de entorno sean parámetros de configuración para el OTBR.
--restart=always: Configura el daemon de Docker para que reinicie automáticamente el contenedor si se detiene. Esto garantiza que el OTBR siempre esté en ejecución. openthread/border-router: Especifica la imagen de Docker que se usará para el contenedor. En este caso, es la imagen oficial del router de borde OpenThread.

Visualiza registros de Docker

Usa el siguiente comando en el host para ver los registros:

docker logs otbr

Si OTBR se ejecuta de forma correcta, deberías obtener un resultado similar al siguiente:
