Jaeger Operator for Kubernetes
The Jaeger Operator is an implementation of a Kubernetes Operator.
Getting started
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 -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 3mIn 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.
