Use an Elasticsearch cluster managed by ECK

Managing APM Server, Kibana and Elasticsearch with ECK allows a smooth and secured integration between the stack components. The output configuration of the APM Server is setup automatically to establish a trust relationship with Elasticsearch. Specifying the Kibana reference allows ECK to automatically configure the Kibana endpoint.

1. To deploy an APM Server and connect it to the Elasticsearch cluster and Kibana instance you created in Deploy an Elasticsearch cluster on Kubernetes, apply the following specification:

   cat <<EOF | kubectl apply -f -
   apiVersion: apm.k8s.elastic.co/v1
   kind: ApmServer
   metadata:
     name: apm-server-quickstart
     namespace: default
   spec:
     version: 9.5.6
     count: 1
     elasticsearchRef:
       name: quickstart
     kibanaRef:
       name: quickstart
   EOF
   

   1. A reference to a Kibana instance is only required for APM Server versions 8.0.0 and later.

apiVersion: kibana.k8s.elastic.co/v1
kind: Kibana
config:
  xpack.fleet.packages:
  - name: apm
    version: latest

By default elasticsearchRef targets all nodes in your Elasticsearch cluster. If you want to direct traffic to specific nodes of your cluster, refer to Traffic Splitting for more information and examples.

1. Monitor APM Server deployment.

   You can retrieve details about the APM Server instance:

   kubectl get apmservers
   

   NAME                     HEALTH    NODES    VERSION   AGE
   apm-server-quickstart    green     1        9.5.6      8m
   

   And you can list all the Pods belonging to a given deployment:

   kubectl get pods --selector='apm.k8s.elastic.co/name=apm-server-quickstart'
   

   NAME                                                READY   STATUS    RESTARTS   AGE
   apm-server-quickstart-apm-server-69b447ddc5-fflc6   1/1     Running   0          2m50s
