Docker #

It is possible to run Zigbee2mqtt in a Docker container using the official Zigbee2mqtt Docker image.

This image support the following architectures: 386, amd64, arm/v6, arm/v7, arm64. Since zigbee2mqtt images are manifest listed, Docker will auto-detect the architecture and pull the right image.

Note for Raspberry Pi 1 and zero users: there is a bug in Docker which selects the wrong image architecture. Before executing docker run pull the correct image with docker pull koenkk/zigbee2mqtt --platform linux/arm/v6.

First run the container, this will create the configuration directory. Change configuration.yaml according to your situation and start again.

Running #

Run by executing the following commmand:

docker run \
   -it \
   -v $(pwd)/data:/app/data \
   --device=/dev/ttyACM0 \
   -e TZ=Europe/Amsterdam \
   -v /run/udev:/run/udev:ro \
   --privileged=true \
   koenkk/zigbee2mqtt

Parameters explanation #

-v $(pwd)/data:/app/data: Directory where Zigbee2mqtt stores it configuration
--device=/dev/ttyACM0: Location of adapter (e.g. CC2531)
-v /run/udev:/run/udev:ro --privileged=true: is optional, only required for autodetecting the port

Updating #

To update to the latest Docker image:

docker rm -f [ZIGBEE2MQTT_CONTAINER_NAME]
docker rmi -f [ZIGBEE2MQTT_IMAGE_NAME] # e.g. koenkk/zigbee2mqtt:latest
# Now run the container again, Docker will automatically pull the latest image.

Tags #

The following tags are available:

Latest release version: latest
Latest dev version (based on dev branch): latest-dev
Specific release version, e.g: 1.7.0

Docker Stack device mapping #

This is only relevant when using Docker Stack

Docker stack doesn’t support device mappings with option --devices when deploying a stack in Swam mode. A workaround is to bind the device as volume binding and set the right permissions.

The workaround is based on the solution found at Add support for devices with “service create”, all credits goes this him.

Identify cc2531 device Identify the cc2531 device using the following command:

UDEV Rules

Create a new udev rule for cc2531, idVendor and idProduct must be equal to values from lsusb command. The rule below creates device /dev/cc2531:

 echo "SUBSYSTEM==\"tty\", ATTRS{idVendor}==\"0451\", ATTRS{idProduct}==\"16a8\", SYMLINK+=\"cc2531\",  RUN+=\"/usr/local/bin/docker-setup-cc2531.sh\"" | sudo tee /etc/udev/rules.d/99-cc2531.rules

Reload newly created rule using the following command:

 sudo udevadm control --reload-rules

Create docker-setup-cc2531.sh

 sudo nano /usr/local/bin/docker-setup-cc2531.sh

Copy the following content:

 #!/bin/bash
 USBDEV=`readlink -f /dev/cc2531`
 read minor major < <(stat -c '%T %t' $USBDEV)
 if [[ -z $minor || -z $major ]]; then
     echo 'Device not found'
     exit
 fi
 dminor=$((0x${minor}))
 dmajor=$((0x${major}))
 CID=`docker ps -a --no-trunc | grep koenkk/zigbee2mqtt | head -1 |  awk '{print $1}'`
 if [[ -z $CID ]]; then
     echo 'CID not found'
     exit
 fi
 echo 'Setting permissions'
 echo "c $dmajor:$dminor rwm" > /sys/fs/cgroup/devices/docker/$CID/devices.allow

Set permissions:

 sudo chmod 744 /usr/local/bin/docker-setup-cc2531.sh

Create docker-event-listener.sh

 sudo nano /usr/local/bin/docker-event-listener.sh

Copy the following content:

 #!/bin/bash
 docker events --filter 'event=start'| \
 while read line; do
     /usr/local/bin/docker-setup-cc2531.sh
 done

Set permissions:

 sudo chmod 744 /usr/local/bin/docker-event-listener.sh

Create docker-event-listener.service

 sudo nano /etc/systemd/system/docker-event-listener.service

Copy the following content:

 [Unit]
 Description=Docker Event Listener for TI CC2531 device
 After=network.target
 StartLimitIntervalSec=0
 [Service]
 Type=simple
 Restart=always
 RestartSec=1
 User=root
 ExecStart=/bin/bash /usr/local/bin/docker-event-listener.sh

 [Install]
 WantedBy=multi-user.target

Set permissions:

 sudo chmod 744 /etc/systemd/system/docker-event-listener.service

Reload daemon

 sudo systemctl daemon-reload

Start Docker event listener

 sudo systemctl start docker-event-listener.service

Status Docker event listener

 sudo systemctl status docker-event-listener.service

Enable Docker event listener

 sudo systemctl enable docker-event-listener.service

Verify and deploy Zigbee2Mqtt stack

Now reconnect the cc2531. Verify using the following command:

 ls -al /dev/cc2531

 lrwxrwxrwx 1 root root 7 Sep 28 21:14 /dev/cc2531 -> ttyACM0

Below an example of a docker-stack-zigbee2mqtt.yml:

 version: "3.7"
 services:
   zigbee2mqtt:
     image: koenkk/zigbee2mqtt:latest-dev
     environment:
       - TZ=Europe/Amsterdam
     volumes:
       - /mnt/docker-cluster/zigbee2mqtt/data:/app/data
       - /dev/cc2531:/dev/cc2531
     networks:
       - proxy_traefik-net
     deploy:
       placement:
         constraints: [node.hostname == rpi-3]
       replicas: 1

 networks:
   proxy_traefik-net:
     external: true

In the above example, proxy_traefik-net is the network to connect to the mqtt broker. The constraint makes sure Docker deploys only to this (rpi-3) node, where the cc2531 is connected to. The volume binding /mnt/docker-cluster/zigbee2mqtt/data is the zigbee2mqtt persistent directory, where configuration.yaml is saved.

The zigbee2mqtt configuration.yaml should point to /dev/cc2531:

 [...]
 serial:
   port: /dev/cc2531
 [...]

Deploy the stack:

 docker stack deploy zigbee2mqtt --compose-file docker-stack-zigbee2mqtt.yml

zigbee2mqtt.io
