13.1.1 Install Jaeger

When you download the Istio installation bundle, it contains jaeger.yaml, a basic sample installation to quickly get Jaeger up and running. The jaeger.yaml file is available in the samples/addons folder at the location where you have downloaded the Istio installation files.

Alternatively, install Jaeger separately. See https://istio.io/latest/docs/ops/integrations/jaeger/.

To install Jaeger using the YAML file that is available in the Istio package directory:

1. Move to the Istio package directory. For example, if the package is istio-1.15.0:

   cd istio-1.15.0

2. Install Jaeger.

   kubectl apply -f samples/addons/jaeger.yaml

   Sample response

   deployment.apps/jaeger created
   service/tracing created
   service/zipkin created
   service/jaeger-collector created

3. Run the following command to verify that Jaeger was installed.

   kubectl get all -n istio-system
