Introduction

Repository for building Docker containers for openHAB (Home Automation Server). Comments, suggestions and contributions are welcome!

Image Variants

openhab/openhab:<version>-<architecture>

Version

Architecture:

  • amd64 for most desktop computer (e.g. x64, x86-64, x86_64)
  • armhf for ARMv7 devices 32 Bit (e.g. most RaspberryPi 1/2/3)
  • arm64 for ARMv8 devices 64 Bit (not RaspberryPi 3)

If you are unsure about what your needs are, you probably want to use openhab/openhab:2.0.0-amd64.

Prebuilt Docker Images can be found here: Docker Images

Usage

Important: To be able to use UPnP for discovery the container needs to be started with --net=host.

The following will run openHAB in demo mode on the host machine:

docker run -it --name openhab --net=host openhab/openhab:2.0.0-amd64

NOTE: Although this is the simplest method to getting openHAB up and running, but it is not the prefered method. To properly run the container, please specify a host volume for the directories.

Starting with Docker named volumes (for beginners)

Following configuration uses Docker named data volumes. These volumes will survive, if you delete or upgrade your container. It is a good starting point for beginners. The volumes are created in the Docker volume directory. You can use docker inspect openhab to locate the directories (e.g. /var/lib/docker/volumes) on your host system. For more information visit Manage data in containers:

Running from command line

docker run \
        --name openhab \
        --net=host \
        -v /etc/localtime:/etc/localtime:ro \
        -v /etc/timezone:/etc/timezone:ro \
        -v openhab_addons:/openhab/addons \
        -v openhab_conf:/openhab/conf \
        -v openhab_userdata:/openhab/userdata \
        -d \
        --restart=always \
        openhab/openhab:2.0.0-amd64

Running from compose-file.yml

Create the following docker-compose.yml and start the container with docker-compose up -d

openhab:
  image: "openhab/openhab:2.0.0-amd64"
  restart: always
  net: host
  volumes:
    - "/etc/localtime:/etc/localtime:ro"
    - "/etc/timezone:/etc/timezone:ro"
    - "openhab_addons:/openhab/addons"
    - "openhab_conf:/openhab/conf"
    - "openhab_userdata:/openhab/userdata"
  environment:
    OPENHAB_HTTP_PORT: "8080"
    OPENHAB_HTTPS_PORT: "8443"

Running openHAB with libpcap support

You can run all openHAB images with libpcap support. This enables you to use the Amazon Dashbutton Binding in the Docker container. For that feature to work correctly, you need to run the image as root user. Create the following docker-compose.yml and start the container with docker-compose up -d

openhab:
  container_name: openhab
  image: "openhab/openhab:2.0.0-amd64"
  restart: always
  net: host
  user: root
  cap_add:
    - NET_ADMIN
    - NET_RAW
  volumes:
    - "/etc/localtime:/etc/localtime:ro"
    - "/etc/timezone:/etc/timezone:ro"
    - "openhab_conf:/openhab/conf"
    - "openhab_userdata:/openhab/userdata"
    - "openhab_addons:/openhab/addons"

If you could provide a method to run libpcap support in user mode please open a pull request.

Starting with Docker mounting a host directory (for advanced user)

You can mount a local host directory to store your configuration files. If you followed the beginners guide, you do not need to read this section. When using mounted volumes Docker only mounts existing data into the openHAB container. If you have no configuration files in this folder, openHAB will not start. You can copy the initial configutration files from the openHab image to the mounted volume. First you need to create the host directories.

mkdir /opt/openhab/ && \
mkdir /opt/openhab/addons/ && \
mkdir /opt/openhab/conf/ && \
mkdir /opt/openhab/userdata/ && \
chown 9001.9001 /opt/openhab -R

By default the openHAB user runs as user id 9001. Next copy the initial configuration files from the openHAB image to your host folder:

docker run --rm \
  --user 9001
  -v /opt/openhab/addons:/openhab/addons \
  -v /opt/openhab/conf:/openhab/conf \
  -v /opt/openhab/userdata:/openhab/userdata \
  openhab/openhab:2.0.0-amd64 \
  sh -c 'cp -av /openhab/userdata.dist/* /openhab/userdata/ && \
  cp -av /openhab/conf.dist/* /openhab/conf/'

You should now be able to run the container with following command:

sudo docker run \
  --user 9001 \
  --name openhab \
  --net=host \
  -v /etc/localtime:/etc/localtime:ro \
  -v /etc/timezone:/etc/timezone:ro \
  -v /opt/openhab/addons:/openhab/addons \
  -v /opt/openhab/conf:/openhab/conf \
  -v /opt/openhab/userdata:/openhab/userdata \
  openhab/openhab:2.0.0-amd64

Accessing the console

You can connect to a console of an already running openHAB container with following command:

  • docker ps - lists all your currently running container
  • docker exec -it openhab /openhab/runtime/bin/client - connect to openHAB container by name
  • docker exec -it c4ad98f24423 /openhab/runtime/bin/client - connect to openHAB container by id

The default password for the login is habopen.

Debug Mode

You can run a new container with the command docker run -it openhab/openhab:2.0.0-amd64 ./start_debug.sh to get into the debug shell.

Environment variables

  • EXTRA_JAVA_OPTS=""
  • LC_ALL=en_US.UTF-8
  • LANG=en_US.UTF-8
  • LANGUAGE=en_US.UTF-8
  • OPENHAB_HTTP_PORT=8080
  • OPENHAB_HTTPS_PORT=8443
  • USER_ID=9001

By default the openHAB user in the container is running with:

  • uid=9001(openhab) gid=9001(openhab) groups=9001(openhab)

Parameters

  • -p 8080 - the port of the webinterface
  • -v /openhab/addons - custom openhab addons
  • -v /openhab/conf - openhab configs
  • -v /openhab/userdata - openhab userdata directory
  • --device=/dev/ttyUSB0 - attach your devices like RFXCOM or Z-Wave Sticks to the container

Building the image

Checkout the github repository and then run these commands:

$ docker build -t openhab/openhab .
$ docker run -it openhab/openhab server
