The root user is required to persist state in a hostPath volume and to trust the Elasticsearch CA in Fleet mode. See Storing local state in host path volume for options to not run the Agent container as root.

Check Configuration Examples for more ready-to-use manifests.

ECK automatically configures secure connections between all components. Fleet will be set up, and all agents are enrolled in the default policy.

Monitor the status of Fleet Server and Elastic Agent.

kubectl get agent

NAME                       HEALTH   AVAILABLE   EXPECTED   VERSION      AGE
elastic-agent-quickstart   green    3           3          8.13.2    14s
fleet-server-quickstart    green    1           1          8.13.2    19s

List all the Pods belonging to a given Elastic Agent specification.

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

NAME                                   READY   STATUS    RESTARTS   AGE
elastic-agent-quickstart-agent-t49fd   1/1     Running   0          54s
elastic-agent-quickstart-agent-xbcxr   1/1     Running   0          54s
elastic-agent-quickstart-agent-zqp55   1/1     Running   0          54s

Access logs for one of the Pods.

kubectl logs -f elastic-agent-quickstart-agent-xbcxr

Configure the policy used by Elastic Agents. Check Elastic Agent policies for more details.
