Quickstart

edit

This functionality is in technical preview and may be changed or removed in a future release. Elastic will work to fix any issues, but features in technical preview are not subject to the support SLA of official GA features.

Add the following specification to create a minimal Logstash deployment that will listen to a Beats agent or Elastic Agent configured to send to Logstash on port 5044, create the service and write the output to an Elasticsearch cluster named quickstart, created in the Elasticsearch quickstart.

cat <<EOF | kubectl apply -f -

  1. Check the status of Logstash

    kubectl get logstash
    NAME              AVAILABLE   EXPECTED   AGE   VERSION
    quickstart        3           3          4s    8.15.3
  2. List all the Pods that belong to a given Logstash specification.

    kubectl get pods --selector='logstash.k8s.elastic.co/name=quickstart'
    NAME              READY   STATUS    RESTARTS   AGE
    quickstart-ls-0   1/1     Running   0          91s
  3. Access logs for a Pod.
kubectl logs -f quickstart-ls-0
