# WebThings Gateway

Docker image based on Debian Buster for running the
[WebThings Gateway](https://github.com/WebThingsIO/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](https://docs.docker.com/docker-for-mac/) or
[Docker for Windows](https://docs.docker.com/docker-for-windows/) due to
[this](https://github.com/docker/for-mac/issues/68) and
[this](https://github.com/docker/for-win/issues/543).

## Usage

* On Linux:

```shell
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:

```shell
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](https://en.wikipedia.org/wiki/List_of_tz_database_time_zones#List).
* `-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:

```json
{
"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:

```shell
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//gateway"`
* `--build-arg "gateway_branch="`
* `--build-arg "gateway_addon_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`.
