+# KIND
+
+An example of configuration for deploying Elasticsearch chart on [Kind][].
+
+You can use `make install` to deploy it.
+
+Note that this configuration should be used for test only and isn't recommended
+for production.
+
+## Current issue
+
+There is currently an [kind issue][] with mount points created from PVCs not writeable by non-root users.
+[kubernetes-sigs/kind#1157][] should fix it in a future release.
+
+Meanwhile, the workaround is to install manually [Rancher Local Path Provisioner][] and use `local-path` storage class for Elasticsearch volumes (see [Makefile][] instructions).
