```console
--driver docker-container --driver-opt image=moby/buildkit:master,network=host

**Examples**
#### Use a custom network
```console
$ docker network create foonet
$ docker buildx create --name builder --driver docker-container --driver-opt network=foonet --use
$ docker buildx inspect --bootstrap
$ docker inspect buildx_buildkit_builder0 --format={{.NetworkSettings.Networks}}

#### OpenTelemetry support

`JAEGER_TRACE` environment variable to the collection address using the `driver-opt`:
```console
$ docker run -d --name jaeger -p 6831:6831/udp -p 16686:16686 jaegertracing/all-in-one
$ docker buildx create --name builder --driver docker-container --driver-opt network=host --driver-opt env.JAEGER_TRACE=localhost:6831 --use
