# OpenTracing
|
|
|
|
Using the third party module [opentracing-contrib/nginx-opentracing](https://github.com/opentracing-contrib/nginx-opentracing) the NGINX ingress controller can configure NGINX to enable [OpenTracing](http://opentracing.io) instrumentation.
|
|
By default this feature is disabled.
|
|
|
|
To enable the instrumentation we just need to enable the instrumentation in the configuration configmap and set the host where we should send the traces.
|
|
|
|
In the [rnburn/zipkin-date-server](https://github.com/rnburn/zipkin-date-server)
|
|
github repository is an example of a dockerized date service. To install the example and zipkin collector run:
|
|
|
|
```
|
|
kubectl create -f https://raw.githubusercontent.com/rnburn/zipkin-date-server/master/kubernetes/zipkin.yaml
|
|
kubectl create -f https://raw.githubusercontent.com/rnburn/zipkin-date-server/master/kubernetes/deployment.yaml
|
|
```
|
|
|
|
Also we need to configure the NGINX controller configmap with the required values:
|
|
|
|
```
|
|
$ echo '
|
|
apiVersion: v1
|
|
kind: ConfigMap
|
|
data:
|
|
enable-opentracing: "true"
|
|
zipkin-collector-host: zipkin.default.svc.cluster.local
|
|
metadata:
|
|
name: nginx-configuration
|
|
namespace: ingress-nginx
|
|
labels:
|
|
app: ingress-nginx
|
|
' | kubectl replace -f -
|
|
```
|
|
|
|
Using curl we can generate some traces:
|
|
|
|
```console
|
|
$ curl -v http://$(minikube ip)
|
|
$ curl -v http://$(minikube ip)
|
|
```
|
|
|
|
In the zipkin interface we can see the details:
