# Dagger Operator Manual
|
|
|
|
## Custom buildkit setup
|
|
|
|
Dagger can be configured to use an existing buildkit daemon, running either locally or remotely. This can be done using two environment variables: `BUILDKIT_HOST` and `DOCKER_HOST`.
|
|
|
|
To use a buildkit daemon listening on TCP port `1234` on localhost:
|
|
|
|
```
|
|
$ export BUILDKIT_HOST=tcp://localhost:1234
|
|
```
|
|
|
|
To use a buildkit daemon running in a container named "super-buildkit" on the local docker host:
|
|
|
|
```
|
|
$ export BUILDKIT_HOST=docker-container://super-buildkit
|
|
```
|
|
|
|
To use a buildkit daemon running on a remote docker host (be careful to properly secure remotely accessible docker hosts!)
|
|
|
|
```
|
|
$ export BUILDKIT_HOST=docker-container://super-buildkit
|
|
$ export DOCKER_HOST=tcp://my-remote-docker-host:2376
|
|
```
|
|
|
|
|
|
## OpenTracing Support
|
|
|
|
Both Dagger and buildkit support opentracing. To capture traces to
|
|
[Jaeger](https://github.com/jaegertracing/jaeger), ), set the `JAEGER_TRACE` environment variable to the collection address.
|
|
|
|
A `docker-compose` file is available to help bootstrap the tracing environment:
|
|
|
|
```sh
|
|
docker-compose -f ./tracing.compose.yaml up -d
|
|
export JAEGER_TRACE=localhost:6831
|
|
export BUILDKIT_HOST=docker-container://dagger-buildkitd-jaeger
|
|
|
|
dagger compute ...
|
|
```
|
|
|
|
You can then go to [http://localhost:16686/](http://localhost:16686/) in your browser to see the traces.
