# Setup

A guide to setup elasticsearch on Kubernetes cluster using "Logging Operator".

Elasticsearch, Fluentd, and Kibana setup can be done by `kubectl` and `helm`. The API for information for elasticsearch is:-

## Elasticsearch

Elasticsearch API information:-

```yaml
---
apiVersion: logging.opstreelabs.in/v1alpha1
kind: Elasticsearch
```

### Kubectl <a href="#kubectl" id="kubectl"></a>

For deployment using kubectl, we can use [config/samples/elasticsearch.yaml](https://github.com/OT-CONTAINER-KIT/logging-operator/blob/master/config/samples/elasticsearch-example.yaml) file.

```
kubectl apply -f config/samples/elasticsearch-example.yaml
```

Elasticsearch configurated can be updated in the same file.

### Helm <a href="#helm" id="helm"></a>

Helm can also be used to setup elasticsearch. Get into the directory [helm-charts/logging-setup](https://github.com/OT-CONTAINER-KIT/logging-operator/tree/master/helm-charts/logging-setup).

```bash
helm upgrade elastic-stack ./ -f values.yaml \
    --set elasticsearch.enabled=true \
    --set elasticsearch.master.enabled=true \
    --set elasticsearch.master.replicas=3 \
    --set elasticsearch.data.enabled=true \
    --set elasticsearch.data.replicas=3 \
    --set elasticsearch.client.enabled=true \
    --set elasticsearch.client.replicas=1 \
    --set elasticsearch.ingestion.enabled=true \
    --set elasticsearch.ingestion.replicas=1 \
    --namespace logging-operator --install
```

Validate the elasticsearch cluster.

## Fluentd

Fluentd API information:-

```yaml
---
apiVersion: logging.opstreelabs.in/v1alpha1
kind: Fluentd
```

### Kubectl

For deployment using kubectl, we can use [config/samples/fluentd.yaml](https://github.com/OT-CONTAINER-KIT/logging-operator/blob/master/config/samples/fluentd-example.yaml) file.

```bash
kubectl apply -f config/samples/fluentd-example.yaml
```

Fluentd configurated can be updated in the same file.

### Helm <a href="#helm" id="helm"></a>

Helm can also be used to setup fluentd. Get into the directory [helm-charts/logging-setup](https://github.com/OT-CONTAINER-KIT/logging-operator/tree/master/helm-charts/logging-setup).

```bash
helm upgrade fluentd-stack ./ \
    -f values.yaml --set fluentd.enabled=true \
    --namesapce logging-operator --install
```

Validate fluentd status

## Kibana

Kibana API information:-

```yaml
---
apiVersion: logging.opstreelabs.in/v1alpha1
kind: Kibana
```

### Kubectl

For deployment using kubectl, we can use [config/samples/kibana.yaml](https://github.com/OT-CONTAINER-KIT/logging-operator/blob/master/config/samples/kibana-example.yaml) file.

```bash
kubectl apply -f config/samples/kibana-example.yaml
```

Kibana configuration can be updated in the same file.

### Helm <a href="#helm" id="helm"></a>

Helm can also be used to setup kibana. Get into the directory [helm-charts/logging-setup](https://github.com/OT-CONTAINER-KIT/logging-operator/tree/master/helm-charts/logging-setup).

```bash
helm upgrade kibana-stack ./ \
    -f values.yaml --set kibana.enabled=true \
    --namespace logging-operator --install
```
