Managing both APM Server and Elasticsearch by ECK allows a smooth and secured integration between the two. The output configuration of the APM Server is setup automatically to establish a trust relationship with Elasticsearch.
To deploy an APM Server and connect it to the cluster you created in the quickstart, 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: 8.12.2 count: 1 elasticsearchRef: name: quickstart EOF
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.
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 8.12.2 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
