# KIND

This example deploy a 3 nodes Elasticsearch 7.16.2 cluster on [Kind][]
using [custom values][].

Note that this configuration should be used for test only and isn't recommended
for production.

Note that Kind < 0.7.0 are affected by a [kind issue][] with mount points
created from PVCs not writable by non-root users. [kubernetes-sigs/kind#1157][]
fix it in Kind 0.7.0.

The workaround for Kind < 0.7.0 is to install manually
[Rancher Local Path Provisioner][] and use `local-path` storage class for
Elasticsearch volumes (see [Makefile][] instructions).


## Usage

* For Kind >= 0.7.0: Deploy Elasticsearch chart with the default values: `make install`
* For Kind < 0.7.0: Deploy Elasticsearch chart with `local-path` storage class: `make install-local-path`

* You can now setup a port forward to query Elasticsearch API:

  ```
  kubectl port-forward svc/elasticsearch-master 9200
  curl localhost:9200/_cat/indices
  ```
