# How to setup BCO via Docker

Follow the instructions step by step in order to setup your own home cube.

# Define Default User

If you want to use the current user as the default one, just execute the following command. Otherwise store the name of the default user in the following variable:

export DEFAULT_USER=$(whoami)

# Setup Docker Environment

Follow the official setup guidelines at Docker Docs
- Short summary for the pi:
  1. curl -fsSL https://get.docker.com -o get-docker.sh
  2. sudo sh get-docker.sh
Add default user to docker group

sudo usermod -aG docker ${DEFAULT_USER}

HINT

All following docker commands are performed as root via the sudo prefix since this is the default for the PI. In case you setup BCO in a rootless docker environment, then you have to remove the sudo prefix before performing each docker command. Otherwise it could happen that all containers are deployed to the docker v1 environment of the root user.

# MQTT Broker Setup

# Create Docker Container

echo -e "allow_anonymous true\nlistener 1883" > $HOME/.mosquitto.conf && \
sudo docker run \
  --name mosquitto \
  --publish 1883:1883 \
  --volume $HOME/.mosquitto.conf:/mosquitto/config/mosquitto.conf \
  --restart=always \
  --log-driver=local \
  -d \
  eclipse-mosquitto

At this stage, you can follow the bco demo setup in case you just want to play around with BCO without any smart home devices being involved.

# Openhab Setup

Create a new openHAB user + group

sudo adduser --system --shell /usr/sbin/nologin openhab
sudo addgroup --system openhab
sudo usermod -a -G openhab openhab

Enable the openHAB user to access usb gateways such as zwave or zigbee sticks

sudo usermod -a -G dialout openhab
sudo usermod -a -G tty openhab

# Add the default user to the openHAB group

sudo usermod -a -G openhab ${DEFAULT_USER}

# Setup Z-Wave USB Stick

INFO

Skip this subsection if you do not have a Z-Wave USB Stick!

At this point, make sure your Z-Wave USB Stick is plugged in and that it is available under the following path:

export ZWAVE_STICK=--device=/dev/ttyACM0

# Deploy the openHAB Docker

sudo docker run \
    --name openhab \
    --net=host \
    -v /etc/localtime:/etc/localtime:ro \
    -v /etc/timezone:/etc/timezone:ro \
    -v openhab_conf:/openhab/conf \
    -v openhab_userdata:/openhab/userdata \
    -v openhab_addons:/openhab/addons \
    --detach \
    -e USER_ID=$(id -u openhab) \
    -e GROUP_ID=$(getent group openhab | cut -d: -f3) \
    --restart=always \
    --log-driver=local \

# Deploy the BCO Webapp Docker

The docker deploys a local webserver thats serving the BCO webapp within your local network. This supports an installation free control of your home environment on any device thats offers a web browser.

INFO

If port 80 is already in use you can alter the X in --publish X:80 in order to refer to another port (e. g. --publish 8282:80).

sudo docker run \
    --name bco-webapp \
    --publish 80:80 \
    --volume /etc/localtime:/etc/localtime:ro \
    --volume /etc/timezone:/etc/timezone:ro \
    --detach \
    --restart=always \

# Enable BCO to access the openHAB sitemap directory in order to generate or update sitemaps

Make BCO user a member of the openHAB group

sudo chmod -R g+rwX /var/lib/docker/volumes/openhab_conf/_data/sitemaps
sudo chgrp bco /var/lib/docker/volumes/openhab_conf/_data/sitemaps

# Setup Portainer as Docker Management Tool

The official installation can be found at: Portainer Doc or use this shortcut:

sudo docker volume create portainer_data
sudo docker run \
    -d -p 8000:8000 \
    -p 9000:9000 \
    --name portainer \
    --restart=always \
    --log-driver=local \
    -v /var/run/docker.sock:/var/run/docker.sock \
    -v portainer_data:/data portainer/portainer-ce

# Setup auto update service with watchtower

Watchtower can be used to automatically keep your docker containers up-to-date. The following modifications has been applied:

WATCHTOWER_CLEANUP cleans up images that has been replaced by newer ones.
WATCHTOWER_INCLUDE_STOPPED even update stopped containers.
WATCHTOWER_TIMEOUT give components more time to perform a proper container shutdown.
-v /etc/timezone:/etc/timezone:ro use the timezone of the hosts system.

Checkout the watchtower documentation for more details.

# Setup Watchtower as a daemon service

Once watchtower is deployed as a daemon service, it will check every 300 seconds for new container images. In case a new image is available, the container will be stopped, updated and started after the update has finished.

Use the following command to setup watchtower as a daemon:

sudo docker run -d \
    --name watchtower \
    -v /var/run/docker.sock:/var/run/docker.sock \
    -v /etc/timezone:/etc/timezone:ro \
    --restart=always \
    --log-driver=local \
    --env WATCHTOWER_CLEANUP=true \
    --env WATCHTOWER_INCLUDE_STOPPED=true \
    --env WATCHTOWER_TIMEOUT=60 \
    containrrr/watchtower:latest

# Setup Watchtower as a one shot service

In case you still want to be the one who is in change when updates should be performed, you can setup watchtower as a one shot service. Therefore, updates are only checked in case you manually start the watchtower container. Once started, watchtower will update all containers and stop itself afterwards again.

Use the following command to setup watchtower as aon shot service.

sudo docker run -d \
    --name watchtower \
    -v /var/run/docker.sock:/var/run/docker.sock \
    -v /etc/timezone:/etc/timezone:ro \
    --log-driver=local \
    --env WATCHTOWER_CLEANUP=true \
    --env WATCHTOWER_INCLUDE_STOPPED=true \
    --env WATCHTOWER_TIMEOUT=60 \
    --env WATCHTOWER_RUN_ONCE=true \
