+# Elastic Cloud on Kubernetes - (ECK)
+
+This [Fabrikate](https://github.com/microsoft/fabrikate) definition generates the Kubernetes resource manifests for [ECK-Elastic Cloud on Kubernetes](https://github.com/elastic/cloud-on-k8s). ECK (Elastic Cloud on Kubernetes) encompasses the Elasticsearch operator.
+
+## Usage
+
+For customizing your elasticsearch cluster, modify the quickstart sample in the [eck-cluster.yaml](manifests/eck-cluster.yaml) with your own configuration. The default configuration is listed below:
+
+```yaml
+apiVersion: elasticsearch.k8s.elastic.co/v1alpha1
+kind: Elasticsearch
+metadata:
+  name: quickstart
+  namespace: elasticsearch
+spec:
+  version: 7.2.0
+  nodes:
+  - nodeCount: 1
+    config:
+      node.master: true
+      node.data: true
+      node.ingest: true
+```
+
+## Deploy ECK
+
+1. Modify the  Elasticsearch to your configuration
+
+> `kubectl -n elasticsearch apply -f manifests/eck-cluster.yaml`
+
+
+A quickstart sample cluster is deployed by default.
+
+More information about deploying ECK can be found [here](https://www.elastic.co/guide/en/cloud-on-k8s/current/k8s-quickstart.html#k8s-deploy-eck)
+
+## Verify elasticsearch
+You can verify the deployment succeeded by calling the elasticsearch API.
+
+1. Fetch the elasticsearch password
+> `kubectl -n elasticsearch get secret quickstart-es-elastic-user -o=jsonpath='{.data.elastic}' | base64 --decode`
+
+
+2. Portforward
+> `kubectl -n elasticsearch port-forward service/quickstart-es-http 9200`
+
+3. Call the endpoint
+> `curl -u "elastic:<password>" -k "https://localhost:9200"`
+
+4. Monitor the operator logs
+
+> `kubectl -n elastic-system logs -f statefulset.apps/elastic-operator`
