Use an Elasticsearch cluster managed by ECK

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: 8.15.3
  count: 1
  elasticsearchRef:
    name: quickstart
EOF

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        8.15.3      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
