<p>For instructions on deploying a single Pulsar cluster manually rather than using Terraform and Ansible, see <a href="/docs/en/2.9.1/deploy-bare-metal">Deploying a Pulsar cluster on bare metal</a>. For instructions on manually deploying a multi-cluster Pulsar instance, see <a href="/docs/en/2.9.1/deploy-bare-metal-multi-cluster">Deploying a Pulsar instance on bare metal</a>.</p>
</blockquote>
<p>One of the easiest ways to get a Pulsar <a href="/docs/en/2.9.1/reference-terminology#cluster">cluster</a> running on <a href="https://aws.amazon.com/">Amazon Web Services</a> (AWS) is to use the <a href="https://terraform.io">Terraform</a> infrastructure provisioning tool and the <a href="https://www.ansible.com">Ansible</a> server automation tool. Terraform can create the resources necessary for running the Pulsar cluster---<a href="https://aws.amazon.com/ec2/">EC2</a> instances, networking and security infrastructure, etc.---While Ansible can install and run Pulsar on the provisioned resources.</p>

<p>In order to install a Pulsar cluster on AWS using Terraform and Ansible, you need to prepare the following things:</p>
<ul>
<li>An <a href="https://aws.amazon.com/account/">AWS account</a> and the <a href="https://aws.amazon.com/cli/"><code>aws</code></a> command-line tool</li>
<li>Python and <a href="https://pip.pypa.io/en/stable/">pip</a></li>
<li>The <a href="https://github.com/adammck/terraform-inventory"><code>terraform-inventory</code></a> tool, which enables Ansible to use Terraform artifacts</li>
</ul>
<p>You also need to make sure that you are currently logged into your AWS account via the <code>aws</code> tool:</p>
<pre><code class="hljs css language-bash">$ aws configure
</code></pre>

<p>You can install Terraform using the instructions <a href="https://learn.hashicorp.com/tutorials/terraform/install-cli">here</a>.</p>
<p>You also need to have the Terraform and Ansible configuration for Pulsar locally on your machine. You can find them in the <a href="https://github.com/apache/pulsar">GitHub repository</a> of Pulsar, which you can fetch using Git commands:</p>

<blockquote>
<p>If you already have an SSH key and want to use it, you can skip the step of generating an SSH key and update <code>private_key_file</code> setting
in <code>ansible.cfg</code> file and <code>public_key_path</code> setting in <code>terraform.tfvars</code> file.</p>
<p>For example, if you already have a private SSH key in <code>~/.ssh/pulsar_aws</code> and a public key in <code>~/.ssh/pulsar_aws.pub</code>,
follow the steps below:</p>
<ol>
<li>update <code>ansible.cfg</code> with following values:</li>
</ol>
<pre><code class="hljs css language-shell">private_key_file=~/.ssh/pulsar_aws
</code></pre>
<ol start="2">
<li>update <code>terraform.tfvars</code> with following values:</li>
</ol>
<pre><code class="hljs css language-shell">public_key_path=~/.ssh/pulsar_aws.pub
</code></pre>
</blockquote>
<p>In order to create the necessary AWS resources using Terraform, you need to create an SSH key. Enter the following commands to create a private SSH key in <code>~/.ssh/id_rsa</code> and a public key in <code>~/.ssh/id_rsa.pub</code>:</p>
<pre><code class="hljs css language-bash">$ ssh-keygen -t rsa
</code></pre>
<p>Do <em>not</em> enter a passphrase (hit <strong>Enter</strong> instead when the prompt comes out). Enter the following command to verify that a key has been created:</p>
<pre><code class="hljs css language-bash">$ ls ~/.ssh
id_rsa id_rsa.pub

<pre><code class="hljs css language-bash">$ terraform init
<span class="hljs-comment"># This will create a .terraform folder</span>
</code></pre>
<p>After that, you can apply the default Terraform configuration by entering this command:</p>

<p>Then you see this prompt below:</p>
<pre><code class="hljs css language-bash">Do you want to perform these actions?
Terraform will perform the actions described above.
Only <span class="hljs-string">'yes'</span> will be accepted to approve.

<p>Before you run the Pulsar playbook, you need to mount the disks to the correct directories on those bookie nodes. Since different type of machines have different disk layout, you need to update the task defined in <code>setup-disk.yaml</code> file after changing the <code>instance_types</code> in your terraform config,</p>
<p>To setup disks on bookie nodes, enter this command:</p>
<pre><code class="hljs css language-bash">$ ansible-playbook \
--user=<span class="hljs-string">'ec2-user'</span> \
--inventory=`<span class="hljs-built_in">which</span> terraform-inventory` \
setup-disk.yaml
</code></pre>
<p>After that, the disks is mounted under <code>/mnt/journal</code> as journal disk, and <code>/mnt/storage</code> as ledger disk.
Remember to enter this command just only once. If you attempt to enter this command again after you have run Pulsar playbook, your disks might potentially be erased again, causing the bookies to fail to start up.</p>
