+# PostgreSQL as Kubernetes Storage
+
+Kamaji offers the possibility of having a different storage system than `etcd` thanks to [kine](https://github.com/k3s-io/kine). One of the implementations is [PostgreSQL](https://www.postgresql.org/).
+
+Kamaji project is developed using [kind](https://kind.sigs.k8s.io), therefore, a PostgreSQL instance must be deployed in advance into the local kubernetes cluster in order to be used as storage for the tenants.
+For the sake of simplicity, the [cloudnative-pg](https://cloudnative-pg.io/) Operator will be used to simplify the setup of it.
+
+There is a Makefile to help with the process:
+
+## Setup
+
+```bash
+$ make postgresql
+```
+
+This target will install the `cloudnative-pg`, creating the PostgreSQL instance in the Kamaji Namespace, along with the generation of the required Secret resource for the kine integration.
+
+This action is idempotent and doesn't overwrite values if they already exist.

+
+## Operator setup
+
+```bash
+$ make cnpg-setup
+```
+
+This target will apply all the required manifests with the `cloudnative-pg` CRD, and required RBAC, and Deployment.
+
+Release [v1.16.0](https://github.com/cloudnative-pg/cloudnative-pg/releases/tag/v1.16.0) has been tested successfully.
+
+## SSL certificate Secret generation
+
+```bash
+$ make postgresql-secret
+```
+
+This target will download locally the `kubectl-cnpg` utility to generate an SSL certificate required to secure the connection to the PostgreSQL instance.
+
+## Kine Secret generation
+
+```bash
+$ make postgresql-kine-secret
+```
+
+Generate the Kine secret required for Kamaji.
+
+> Requires the generation of the `postgresql-secret`
+
+## Teardown
+
+```bash
+$ make postgresql-destroy
+```
+
+This will lead to the deletion of the `cloudnative-pg` Operator, along with any instance, and related secrets.
+
+This action is idempotent.
