# emicklei/go-restful instrumentation example
|
||||
|
||||
An HTTP server using emicklei/go-restful and instrumentation. The server has a
|
||||
`/users/{id:[0-9]+}` endpoint. The server generates span information to
|
||||
`stdout`.
|
||||
|
||||
These instructions assume you have
|
||||
[docker-compose](https://docs.docker.com/compose/) installed.
|
||||
|
||||
Bring up the `go-restful-server` and `go-restful-client` services to run the
|
||||
example:
|
||||
|
||||
```sh
|
||||
docker-compose up --detach go-restful-server go-restful-client
|
||||
```
|
||||
|
||||
The `go-restful-client` service sends just one HTTP request to `go-restful-server`
|
||||
and then exits. View the span generated by `go-restful-server` in the logs:
|
||||
|
||||
```sh
|
||||
docker-compose logs go-restful-server
|
||||
```
|
||||
|
||||
Shut down the services when you are finished with the example:
|
||||
|
||||
```sh
|
||||
docker-compose down
|
||||
```
