+# Install Percona Operator for PostgreSQL on Digital Ocean Kubernetes Service (DOKS)
+
+This guide shows you how to deploy Percona Operator for PostgreSQL on Digital Ocean Kubernetes Service (DOKS) with default parameters. 
+
+The document assumes some experience with the
+platform. For more information on the DOKS, see the [Digital Ocean Kubernetes Service official documentation :octicons-link-external-16:](https://docs.digitalocean.com/products/kubernetes/).
+
+
+--8<-- "what-you-install.txt"
+
+To customize the installation, refer to [Install Percona Operator for PostgreSQL with customized parameters](custom-install.md).
+
+## Prerequisites
+
+Install and configure the following:
+
+1. [`doctl` Command Line Interface (CLI) :octicons-link-external-16:](https://docs.digitalocean.com/reference/doctl/how-to/install/) to manage DOKS clusters.
+2. A [Digital Ocean personal access token :octicons-link-external-16:](https://docs.digitalocean.com/reference/api/create-personal-access-token/) to grant account access to `doctl`
+3. [kubectl :octicons-link-external-16:](https://cloud.google.com/kubernetes-engine/docs/quickstart#choosing_a_shell) to manage Kubernetes resources.
+
+## Create a DOKS cluster
+
+1. Decide on the following:
+
+    * Cluster name.
+    * Region where you will deploy the cluster
+    * Kubernetes version
+    * A [node pool](https://docs.digitalocean.com/products/kubernetes/how-to/add-node-pools/) for the cluster to reside on.
+
+2. Create a Digital Ocean cluster following the [official documentation :octicons-link-external-16:](https://docs.digitalocean.com/products/kubernetes/how-to/create-clusters/).
+3. Add authentication token or a certificate to your kubectl configuration file to connect. Follow [official documentation :octicons-link-external-16:](https://docs.digitalocean.com/products/kubernetes/how-to/connect-to-cluster/) for steps
+
+## Install the Operator deployment
+
+1. Create a namespace for your cluster and export it as an environment variable to simplify further configuration:
+
+    ```bash
+    kubectl create namespace <namespace>
+    export NAMESPACE=<namespace>
+    ```
+
+2. Create the Custom Resource Definition, set up RBAC, and install the Operator Deployment using the the bundle file:
+
+    ```bash
+    kubectl apply --server-side -f https://raw.githubusercontent.com/percona/percona-postgresql-operator/v{{ release }}/deploy/bundle.yaml -n $NAMESPACE
+    ```
+
+    ??? example "Expected output"
+
+        --8<-- "kubectl-apply-bundle-response.txt"
+
+    As the result you will have the Operator Pod up and running.
+
+## Install Percona Distribution for PostgreSQL
+
+1. Create the Percona Distribution for PostgreSQL cluster:
+
+    ```bash
+    kubectl apply -f https://raw.githubusercontent.com/percona/percona-postgresql-operator/v{{ release }}/deploy/cr.yaml -n $NAMESPACE
+    ```
+
+    ??? example "Expected output"
+
+        ``` {.text .no-copy}
+        perconapgcluster.pgv2.percona.com/cluster1 created
+        ```
+
+2. Check the cluster status. Creation may take a few minutes:
+
+    ```bash
+    kubectl get pg -n $NAMESPACE
+    ```
+
+    ??? example "Expected output"
+
+        --8<-- "kubectl-get-pg-response.txt"
+
+## Verifying the cluster operation
+
+When creation process is over, `kubectl get pg` command will show you the
+cluster status as `ready`, and you can try to connect to the cluster.
+
+{% include 'assets/fragments/connectivity.txt' %}
+
+## Delete the DOKS cluster
+
+To delete the DOKS cluster, run the following command:
+
+```bash
+doctl kubernetes cluster delete <cluster-name>
+```
+
+The cluster deletion may take time.
+
+!!! warning
+
+    After deleting the cluster, all data stored in it will be lost!
