# OpenTelemetry support
|
|
|
|
To capture the trace to [Jaeger](https://github.com/jaegertracing/jaeger), set
|
|
`JAEGER_TRACE` environment variable to the collection address using a `driver-opt`.
|
|
|
|
First create a Jaeger container:
|
|
|
|
```console
|
|
$ docker run -d --name jaeger -p "6831:6831/udp" -p "16686:16686" jaegertracing/all-in-one
|
|
```
|
|
|
|
Then [create a `docker-container` builder](https://docs.docker.com/engine/reference/commandline/buildx_create/)
|
|
that will use the Jaeger instance via the `JAEGER_TRACE` env var:
|
|
|
|
```console
|
|
$ docker buildx create --use \
|
|
--name mybuilder \
|
|
--driver docker-container \
|
|
--driver-opt "network=host" \
|
|
--driver-opt "env.JAEGER_TRACE=localhost:6831"
|
|
```
|
|
|
|
Boot and [inspect `mybuilder`](https://docs.docker.com/engine/reference/commandline/buildx_inspect/):
|
|
|
|
```console
|
|
$ docker buildx inspect --bootstrap
|
|
```
|
|
|
|
Buildx commands should be traced at `http://127.0.0.1:16686/`:
