The Jaeger Operator is an implementation of a Kubernetes Operator.

To install the operator, run:

kubectl create namespace observability
kubectl create -n observability -f https://raw.githubusercontent.com/jaegertracing/jaeger-operator/master/deploy/crds/jaegertracing.io_jaegers_crd.yaml
kubectl create -n observability -f https://raw.githubusercontent.com/jaegertracing/jaeger-operator/master/deploy/service_account.yaml
kubectl create -n observability -f https://raw.githubusercontent.com/jaegertracing/jaeger-operator/master/deploy/role.yaml
kubectl create -n observability -f https://raw.githubusercontent.com/jaegertracing/jaeger-operator/master/deploy/role_binding.yaml
kubectl create -n observability -f https://raw.githubusercontent.com/jaegertracing/jaeger-operator/master/deploy/operator.yaml

The operator will activate extra features if given cluster-wide permissions. To enable that, run:

kubectl create -f https://raw.githubusercontent.com/jaegertracing/jaeger-operator/master/deploy/cluster_role.yaml
kubectl create -f https://raw.githubusercontent.com/jaegertracing/jaeger-operator/master/deploy/cluster_role_binding.yaml

Note that you'll need to download and customize the cluster_role_binding.yaml if you are using a namespace other than observability. You probably also want to download and customize the operator.yaml, setting the env var WATCH_NAMESPACE to have an empty value, so that it can watch for instances across all namespaces.

Once the jaeger-operator deployment in the namespace observability is ready, create a Jaeger instance, like:

kubectl apply -n observability -f - <<EOF
apiVersion: jaegertracing.io/v1
kind: Jaeger
metadata:
  name: simplest
EOF

This will create a Jaeger instance named simplest. The Jaeger UI is served via the Ingress, like:

$ kubectl get ingress
NAME             HOSTS     ADDRESS          PORTS     AGE
simplest-query   *         192.168.122.34   80        3m

In this example, the Jaeger UI is available at http://192.168.122.34.

The official documentation for the Jaeger Operator, including all its customization options, are available under the main Jaeger Documentation.

Sometimes it is preferable to generate plain manifests files instead of running an operator in a cluster. jaeger-operator generate generates kubernetes manifests from a given CR. In this example we apply the manifest generated by examples/simplest.yaml to the namespace jaeger-test:

curl https://raw.githubusercontent.com/jaegertracing/jaeger-operator/master/deploy/examples/simplest.yaml | docker run --rm jaegertracing/jaeger-operator:master generate | kubectl apply -n jaeger-test -f -

It is recommended to deploy the operator instead of generating a static manifest.
