|
<p>This document provides comprehensive guidance for developing extensions for provisioning, including providers, task services, and cluster configurations.</p>
|
|
<h2 id="overview"><a class="header" href="#overview">Overview</a></h2>
|
|
<p>Provisioning supports three types of extensions:</p>
|
|
<ol>
|
|
<li><strong>Providers</strong>: Cloud infrastructure providers (AWS, UpCloud, Local, etc.)</li>
|
|
<li><strong>Task Services</strong>: Infrastructure components (Kubernetes, Cilium, Containerd, etc.)</li>
|
|
<li><strong>Clusters</strong>: Complete deployment configurations (BuildKit, CI/CD, etc.)</li>
|
|
</ol>
|
|
<p>All extensions follow a standardized structure and API for seamless integration.</p>
