WebThings Gateway

Docker image based on Debian Buster for running the WebThings Gateway. The image is built for AMD64, ARMv7, and ARMv8 (AArch64).

Compatibility

While the gateway doesn't necessarily require full local network access, some add-ons may. Therefore, it is best to run with the --network="host" flag. Currently, this flag will not work when using Docker for Mac or Docker for Windows due to this and this.

Usage

  • On Linux:

    docker run \
    -d \
    -e TZ=America/Los_Angeles \
    -v /path/to/shared/data:/home/node/.webthings \
    --network="host" \
    --log-opt max-size=1m \
    --log-opt max-file=10 \
    --name webthings-gateway \
    webthingsio/gateway:latest

  • On Windows or macOS:

    docker run \
    -d \
    -p 8080:8080 \
    -p 4443:4443 \
    -e TZ=America/Los_Angeles \
    -v /path/to/shared/data:/home/node/.webthings \
    --log-opt max-size=1m \
    --log-opt max-file=10 \
    --name webthings-gateway \
    webthingsio/gateway:latest

Parameters

  • -d - Run in daemon mode (in the background)
  • -e TZ=America/Los_Angeles - Set the time zone to America/Los_Angeles. The list of names can be found here.
  • -v /path/to/shared/data:/home/node/.webthings - Change /path/to/shared/data to some local path. We are mounting a directory on the host to the container in order to store the persistent "user profile" data, e.g. add-ons, logs, configuration data, etc.
  • --network="host" - Shares host networking with container (highly recommended, needed by some addons, -p is ignored if this option is used).
  • -p 8080:8080 / -p 4443:4443 - Forward necessary ports to the container (ignored if --network="host" is present).
  • --log-opt max-size=1m - limit the log size to 1 MB
  • --log-opt max-file=10 - limit the number of saved log files to 10
  • --name webthings-gateway - Name of the container.

Changing ports in --network="host" mode

Create a file local.json and map it to /path/to/shared/data/config/local.json (where /path/to/shared/data is the volume mounted to /home/node/.webthings). Contents of the file:

{
  "ports": {
    "https": 8081,
    "http": 8080
  }
}

Edit the ports as you like.

Using docker-compose

docker-compose up -d

Connecting

After running the container, you can connect to it at: http://<host-ip-address>:8080

Building

If you'd like to build an image yourself, run the following:

git clone https://github.com/WebThingsIO/gateway
cd gateway
docker build -t gateway .
docker run \
    -d \
    -e TZ=America/Los_Angeles \
    -v /path/to/shared/data:/home/node/.webthings \
    --network="host" \
    --log-opt max-size=1m \
    --log-opt max-file=10 \
    --name webthings-gateway \
    gateway

You can add the following build args:

  • --build-arg "gateway_url=https://github.com/<your-fork>/gateway"
  • --build-arg "gateway_branch=<your-branch>"
  • --build-arg "gateway_addon_version=<your-version>"

Notes

  • If you need to use Zigbee, Z-Wave, or some other add-on which requires physically attached hardware, you will have to share your device into your container, e.g. --device /dev/ttyACM0:/dev/ttyACM0. They will also need to be owned by GID 20, which corresponds to the dialout group in the container. This can be done using udev rules or something else.
  • If you need to use GPIO in the container (e.g. on a Raspberry Pi host), you will need to either run in privileged mode with --privileged or share in your sysfs filesystem with -v /sys:/sys. The sysfs nodes will also need to be owned by GID 997, which corresponds to the gpio group in the container.
  • If you need to use Bluetooth in the container, you will need to disable BlueZ on the host (if running), e.g. systemctl disable bluetooth, and you will need to run the container in privileged mode, i.e. --privileged.
