OpenTelemetry support
Both Buildx and BuildKit support OpenTelemetry.
To capture the trace to Jaeger,
set JAEGER_TRACE environment variable to the collection address using a
driver-opt.
First create a Jaeger container:
$ docker run -d --name jaeger -p "6831:6831/udp" -p "16686:16686" --restart unless-stopped jaegertracing/all-in-one
Then
create a docker-container builder
that will use the Jaeger instance via the JAEGER_TRACE environment variable:
$ docker buildx create --use \
--name mybuilder \
--driver docker-container \
--driver-opt "network=host" \
--driver-opt "env.JAEGER_TRACE=localhost:6831"
Boot and
inspect mybuilder:
$ docker buildx inspect --bootstrap
Buildx commands should be traced at http://127.0.0.1:16686/:
