This documentation will describe how to Install ZooKeeper on IBM Cloud.

# Requirements/Prerequisites
You will need an IBM Cloud Pay-As-You-Go or Subscription Account type which can be found [here](https://cloud.ibm.com/docs/account?topic=account-accounts).

# Introduction
This docs will describe how to install ZooKeeper on IBM Cloud. These four steps will be needed as follows:

- Step 1: Provision Kubernetes Cluster
- Step 2: Deploy IBM Cloud Block Storage plug-in
- Step 3: Deploy ZooKeeper
- Step 4: Verify Installation

So let's get started.

## Step 1: Provision Kubernetes Cluster

* Search for **Kubernetes** and select **Kubernetes Service** from the list.

> You will be redirected to the [Kubernetes cluster creation](https://cloud.ibm.com/kubernetes/catalog/create) page.

### Option A: Create free Kubernetes Engine:

* Price Plan: Free

> Enter the cluster name of your choice then click **Create** to provision the free Kubernetes Cluster.
> Please wait for few moments to provision the cluster.

### Option B: Create Standard Kubernetes Engine with the following attributes:

* Price Plan: Standard

* Infrastructure: Classic
* Availability: Multi Zone
* Metro: Dallas
* 4 VCPU
* 16 GB RAM
* Worker nodes per zone: 3

> Please wait for a few moments to provision the cluster.

## Step 2: Deploy IBM Cloud Block Storage plug-in

* Just like in step 1, search for "Block Storage" and Click on it.

* Now input the storage details

> N.B. Select location as the cluster location.

* Location > Europe > London > LON02
* Billing Method > Monthly > 20 GB
* OS type > Linux
* IOPS > 2 IOPS/GB

* Click on “I have agreed to the terms and conditions listed below”.

> Now a storage plugin will be available in the dashboard.

## Step 3: Deploy ZooKeeper

* Again Search for **ZooKeeper** and Click on it.

> You will be taken to the **ZooKeeper** deployment page.

In the ZooKeeper creation page add the details below:

* Target: IBM Kubernetes Service
* Method: Helm chart
* Kubernetes cluster: mycluster-free
* Target namespace: zookeeper
* Workspace: zookeeper
* Resource group: Default
