# Logstash configuration examples on Elastic Cloud on Kubernetes
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.
<warning>
  The examples in this section are for illustration purposes only. They should not be considered production-ready. Some of these examples use the `node.store.allow_mmap: false` setting on Elasticsearch which has performance implications and should be tuned for production workloads, as described in [Virtual memory](https://docs-v3-preview.elastic.dev/elastic/docs-content/pull/5568/deploy-manage/deploy/cloud-on-k8s/virtual-memory).
</warning>


## Single pipeline defined in CRD

```sh
kubectl apply -f https://raw.githubusercontent.com/elastic/cloud-on-k8s/3.3/config/recipes/logstash/logstash-eck.yaml
```

Deploys Logstash with a single pipeline defined in the CRD

## Single Pipeline defined in Secret

```sh
kubectl apply -f https://raw.githubusercontent.com/elastic/cloud-on-k8s/3.3/config/recipes/logstash/logstash-pipeline-as-secret.yaml
```

Deploys Logstash with a single pipeline defined in a secret, referenced by a `pipelineRef`

## Pipeline configuration in mounted volume

```sh
kubectl apply -f https://raw.githubusercontent.com/elastic/cloud-on-k8s/3.3/config/recipes/logstash/logstash-pipeline-as-volume.yaml
```

Deploys Logstash with a single pipeline defined in a secret, mounted as a volume, and referenced by `path.config`

## Writing to a custom Elasticsearch index

```sh
kubectl apply -f https://raw.githubusercontent.com/elastic/cloud-on-k8s/3.3/config/recipes/logstash/logstash-es-role.yaml
```

Deploys Logstash and Elasticsearch, and creates an updated version of the `eck_logstash_user_role` to write to a user specified index.

## Creating persistent volumes for PQ and DLQ

```sh
kubectl apply -f https://raw.githubusercontent.com/elastic/cloud-on-k8s/3.3/config/recipes/logstash/logstash-volumes.yaml
```

Deploys Logstash, Beats and Elasticsearch. Logstash is configured with two pipelines:
- a main pipeline for reading from the Beats instance, which will send to the DLQ if it is unable to write to Elasticsearch
- a second pipeline, that will read from the DLQ. In addition, persistent queues are set up. This example shows how to configure persistent volumes outside of the default `logstash-data` persistent volume.


## Elasticsearch and Kibana Stack Monitoring

```sh
kubectl apply -f https://raw.githubusercontent.com/elastic/cloud-on-k8s/3.3/config/recipes/logstash/logstash-monitored.yaml
```

Deploys an Elasticsearch and Kibana monitoring cluster, and a Logstash that will send its monitoring information to this cluster. You can view the stack monitoring information in the monitoring cluster’s Kibana

## Multiple pipelines/multiple Elasticsearch clusters

```sh
kubectl apply -f https://raw.githubusercontent.com/elastic/cloud-on-k8s/3.3/config/recipes/logstash/logstash-multi.yaml
```

Deploys Elasticsearch in prod and qa configurations, running in separate namespaces. Logstash is configured with a multiple pipeline→pipeline configuration, with a source pipeline routing to `prod` and `qa` pipelines.
