<h2 id="what-is-provisioning"><a class="header" href="#what-is-provisioning">What is Provisioning?</a></h2>
<p><strong>Provisioning</strong> is a comprehensive <strong>Infrastructure as Code (IaC)</strong> platform designed to manage complete infrastructure lifecycles: cloud providers, infrastructure services, clusters, and isolated workspaces across multiple cloud/local environments.</p>
<p>Extensible and customizable by design, it delivers type-safe, configuration-driven workflows with enterprise security (encrypted configuration, Cosmian KMS integration, Cedar policy engine, secrets management, authorization and permissions control, compliance checking, anomaly detection) and adaptable deployment modes (interactive UI, CLI automation, unattended CI/CD) suitable for any scale from development to production.</p>
<h3 id="technical-definition"><a class="header" href="#technical-definition">Technical Definition</a></h3>
<p>Declarative Infrastructure as Code (IaC) platform providing:</p>
<ul>
<li><strong>Type-safe, configuration-driven workflows</strong> with schema validation and constraint checking</li>
<li><strong>Modular, extensible architecture</strong>: cloud providers, task services, clusters, workspaces</li>

<li><strong>High-performance state management</strong>:
<ul>
<li>Graph database backend for complex relationships</li>
<li>Real-time state tracking and queries</li>
<li>Multi-model data storage (document, graph, relational)</li>
</ul>
</li>
<li><strong>Enterprise security stack</strong>:
<ul>
<li>Encrypted configuration and secrets management</li>

<h3 id="the-problems-it-solves"><a class="header" href="#the-problems-it-solves">The Problems It Solves</a></h3>
<h4 id="1-multi-cloud-complexity"><a class="header" href="#1-multi-cloud-complexity">1. <strong>Multi-Cloud Complexity</strong></a></h4>
<p><strong>Problem</strong>: Each cloud provider has different APIs, tools, and workflows.</p>
<p><strong>Solution</strong>: Unified abstraction layer with provider-agnostic interfaces. Write configuration once, deploy anywhere.</p>
<pre><code class="language-kcl"># Same configuration works on UpCloud, AWS, or local infrastructure
server: Server {
name = "web-01"
plan = "medium" # Abstract size, provider-specific translation
provider = "upcloud" # Switch to "aws" or "local" as needed
}
</code></pre>
<h4 id="2-dependency-hell"><a class="header" href="#2-dependency-hell">2. <strong>Dependency Hell</strong></a></h4>
<p><strong>Problem</strong>: Infrastructure components have complex dependencies (Kubernetes needs containerd, Cilium needs Kubernetes, etc.).</p>
<p><strong>Solution</strong>: Automatic dependency resolution with topological sorting and health checks.</p>
<pre><code class="language-kcl"># Provisioning resolves: containerd → etcd → kubernetes → cilium
taskservs = ["cilium"] # Automatically installs all dependencies
</code></pre>
<h4 id="3-configuration-sprawl"><a class="header" href="#3-configuration-sprawl">3. <strong>Configuration Sprawl</strong></a></h4>
<p><strong>Problem</strong>: Environment variables, hardcoded values, scattered configuration files.</p>
<p><strong>Solution</strong>: Hierarchical configuration system with 476+ config accessors replacing 200+ ENV variables.</p>
<pre><code>Defaults → User → Project → Infrastructure → Environment → Runtime
</code></pre>
<h4 id="4-imperative-scripts"><a class="header" href="#4-imperative-scripts">4. <strong>Imperative Scripts</strong></a></h4>
<p><strong>Problem</strong>: Brittle shell scripts that dont handle failures, dont support rollback, hard to maintain.</p>
<p><strong>Solution</strong>: Declarative KCL configurations with validation, type safety, and automatic rollback.</p>
<h4 id="5-lack-of-visibility"><a class="header" href="#5-lack-of-visibility">5. <strong>Lack of Visibility</strong></a></h4>
<p><strong>Problem</strong>: No insight into whats happening during deployment, hard to debug failures.</p>
<p><strong>Solution</strong>:</p>
<ul>
<li>Real-time workflow monitoring</li>
<li>Comprehensive logging system</li>
<li>Web-based control center</li>
<li>REST API for integration</li>
</ul>
<h4 id="6-no-standardization"><a class="header" href="#6-no-standardization">6. <strong>No Standardization</strong></a></h4>
<p><strong>Problem</strong>: Each team builds their own deployment tools, no shared patterns.</p>
<p><strong>Solution</strong>: Reusable task services, cluster templates, and workflow patterns.</p>

<h3 id="data-flow"><a class="header" href="#data-flow">Data Flow</a></h3>
<pre><code>1. User defines infrastructure in KCL
2. CLI loads configuration (hierarchical)
3. Configuration validated against schemas
4. Workflow created with operations
5. Orchestrator receives workflow
6. Dependencies resolved (topological sort)
7. Operations executed in order
8. Providers handle cloud operations
9. Task services installed on servers
10. State persisted and monitored
</code></pre>
<h3 id="example-workflow-deploy-kubernetes-cluster"><a class="header" href="#example-workflow-deploy-kubernetes-cluster">Example Workflow: Deploy Kubernetes Cluster</a></h3>
<p><strong>Step 1</strong>: Define infrastructure in KCL</p>
<pre><code class="language-kcl"># infra/my-cluster.k
import provisioning.settings as cfg
settings: cfg.Settings = {
infra = {
name = "my-cluster"
provider = "upcloud"

servers = [
{name = "control-01", plan = "medium", role = "control"}
{name = "worker-01", plan = "large", role = "worker"}
{name = "worker-02", plan = "large", role = "worker"}
]
taskservs = ["kubernetes", "cilium", "rook-ceph"]
}
</code></pre>
<p><strong>Step 2</strong>: Submit to Provisioning</p>
<pre><code class="language-bash">provisioning server create --infra my-cluster
</code></pre>
<p><strong>Step 3</strong>: Provisioning executes workflow</p>
<pre><code>1. Create workflow: "deploy-my-cluster"
2. Resolve dependencies:
- containerd (required by kubernetes)
- etcd (required by kubernetes)
- kubernetes (explicitly requested)
- cilium (explicitly requested, requires kubernetes)
- rook-ceph (explicitly requested, requires kubernetes)
3. Execution order:
a. Provision servers (parallel)
b. Install containerd on all nodes
c. Install etcd on control nodes
d. Install kubernetes control plane
e. Join worker nodes
f. Install Cilium CNI
g. Install Rook-Ceph storage
4. Checkpoint after each step
5. Monitor health checks
6. Report completion
</code></pre>
<p><strong>Step 4</strong>: Verify deployment</p>
<pre><code class="language-bash">provisioning cluster status my-cluster

<h3 id="configuration-hierarchy"><a class="header" href="#configuration-hierarchy">Configuration Hierarchy</a></h3>
<p>Configuration values are resolved through a hierarchy:</p>

3. Workspace Config (workspace/config/provisioning.yaml)
↓ (overridden by)
4. Infrastructure Config (workspace/infra/&lt;name&gt;/config.toml)
↓ (overridden by)
5. Environment Config (workspace/config/prod-defaults.toml)
↓ (overridden by)
6. Runtime Flags (--flag value)
