<h2>Create a keypair</h2>
<p>A keypair is basically a ssh key allowing you to login to your virtual machine</p>
<p>Keypair options Keypairs provide the method to authenticate when logging into a Linux VM. There are several options for how to create them.</p>
<ol>
  <li>Using your existing SSH key</li>
</ol>
<p>Assuming your existing ssh public key is located at <code>~/.ssh/ssh_my_rsa_key.pub</code></p>
<p>Import it using the following command:</p>
<pre><code class="language-plaintext">openstack keypair create --public-key ~/.ssh/ssh_my_rsa_key.pub mykeypair
