<p>This section contains manifests that illustrate common use cases, and can be your starting point in exploring Logstash deployed with ECK. These manifests are self-contained and work out-of-the-box on any non-secured Kubernetes cluster. They all contain a three-node Elasticsearch cluster and a single Kibana instance.</p>

<p>The examples in this section are for illustration purposes only and should not be considered to be production-ready. Some of these examples use the <code class="literal">node.store.allow_mmap: false</code> setting on Elasticsearch which has performance implications and should be tuned for production workloads, as described in <a class="xref" href="k8s-virtual-memory.html" title="Virtual memory">Virtual memory</a>.</p>
