<p>Execution Complete</p>
|
||
<p>Perfect question! Let me explain clearly:</p>
|
||
<p>The Orchestrator IS USED and IS CRITICAL</p>
|
||
<p>That code example was misleading. Here’s the real architecture:</p>
|
||
<p>How It Actually Works</p>
|
||
<p>┌──────────────────────────────────────────────────┐
|
||
│ User runs: provisioning server create –orchestrated
|
||
└───────────────────┬──────────────────────────────┘
|
||
↓
|
||
┌───────────────────────┐
|
||
│ Nushell CLI │
|
||
│ (provisioning) │
|
||
└───────────┬───────────┘
|
||
↓ HTTP POST
|
||
┌───────────────────────────────┐
|
||
│ Rust Orchestrator Daemon │
|
||
│ (provisioning-orchestrator) │
|
||
│ │
|
||
│ • Task Queue │
|
||
│ • Workflow Engine │
|
||
│ • Dependency Resolution │
|
||
│ • Parallel Execution │
|
||
└───────────┬───────────────────┘
|
||
↓ spawns subprocess
|
||
┌───────────────────────────────┐
|
||
│ Nushell Business Logic │
|
||
│ nu -c “use servers/create.nu”│
|
||
│ │
|
||
│ Executes actual provider │
|
||
│ API calls, configuration │
|
||
└───────────────────────────────┘
|
||
The Flow in Detail</p>
|
||
<ol>
|
||
<li>User Command:</li>
|
||
</ol>
|
||
<p>provisioning server create wuji –orchestrated
|
||
2. Nushell CLI submits to orchestrator:</p>
|
||
<h1 id="cli-code"><a class="header" href="#cli-code">CLI code</a></h1>
|
||
<p>http post <a href="http://localhost:9090/workflows/servers/create">http://localhost:9090/workflows/servers/create</a> {
|
||
infra: “wuji”
|
||
params: {…}
|
||
}</p>
|
||
<h1 id="returns-workflow_id--abc-123"><a class="header" href="#returns-workflow_id--abc-123">Returns: workflow_id = “abc-123”</a></h1>
|
||
<ol>
|
||
<li>Orchestrator receives and queues:</li>
|
||
</ol>
|
||
<p>// Orchestrator receives HTTP request
|
||
async fn create_server_workflow(request) {
|
||
let task = Task::new(TaskType::ServerCreate, request);
|
||
task_queue.enqueue(task).await; // Queue for execution
|
||
return workflow_id; // Return immediately
|
||
}
|
||
4. Orchestrator executes via Nushell subprocess:</p>
|
||
<p>// Orchestrator spawns Nushell to run business logic
|
||
async fn execute_task(task: Task) {
|
||
let output = Command::new(“nu”)
|
||
.arg(“-c”)
|
||
.arg(“use /usr/local/lib/provisioning/servers/create.nu; create-server ‘wuji’”)
|
||
.output()
|
||
.await?;</p>
|
||
<pre><code>// Orchestrator manages: retry, checkpointing, monitoring
|
||
</code></pre>
|
||
<p>}
|
||
5. Nushell executes the actual work:</p>
|
||
<h1 id="serverscreatenu"><a class="header" href="#serverscreatenu">servers/create.nu</a></h1>
|
||
<p>export def create-server [name: string] {
|
||
# This is the business logic
|
||
# Calls UpCloud API, creates server, etc.
|
||
let provider = (load-provider)
|
||
$provider | create-vm $name
|
||
}
|
||
Why This Architecture?</p>
|
||
<p>Problem It Solves</p>
|
||
<p>Without Orchestrator (Old Way):</p>
|
||
<p>provisioning → template.nu → cluster.nu → taskserv.nu → provider.nu
|
||
(Deep call stack = crashes!)
|
||
With Orchestrator (Current):</p>
|
||
<p>provisioning → Orchestrator → spawns fresh Nushell subprocess for each task
|
||
(No deep nesting, parallel execution, recovery)
|
||
What Orchestrator Provides</p>
|
||
<p>Task Queue - Reliable execution even if system crashes
|
||
Parallel Execution - Run 10 tasks at once (Rust async)
|
||
Workflow Engine - Handle complex dependencies
|
||
Checkpointing - Resume from failure
|
||
Monitoring - Real-time progress tracking
|
||
What Nushell Provides</p>
|
||
<p>Business Logic - Provider integrations, config generation
|
||
Flexibility - Easy to modify without recompiling
|
||
Readability - Shell-like syntax for infrastructure ops
|
||
Multi-Repo Impact: NONE on Integration</p>
|
||
<p>In Monorepo:</p>
|
||
<p>provisioning/
|
||
├── core/nulib/ # Nushell code
|
||
└── platform/orchestrator/ # Rust code
|
||
In Multi-Repo:</p>
|
||
<p>provisioning-core/ # Separate repo, installs to /usr/local/lib/provisioning
|
||
provisioning-platform/ # Separate repo, installs to /usr/local/bin/provisioning-orchestrator
|
||
Integration is the same:</p>
|
||
<p>Orchestrator calls: nu -c “use /usr/local/lib/provisioning/servers/create.nu”
|
||
Nushell calls: http post <a href="http://localhost:9090/workflows/">http://localhost:9090/workflows/</a>…
|
||
No code dependency, just runtime coordination!</p>
|
||
<p>The Orchestrator IS Essential</p>
|
||
<p>The orchestrator:</p>
|
||
<p>✅ IS USED for all complex operations
|
||
✅ IS CRITICAL for workflow system (v3.0)
|
||
✅ IS REQUIRED for batch operations (v3.1)
|
||
✅ SOLVES deep call stack issues
|
||
✅ PROVIDES performance and reliability
|
||
That misleading code example showed how Platform doesn’t link to Core code, but it absolutely uses the orchestrator for coordination.</p>
|
||
<p>Does this clear it up? The orchestrator is the performance and reliability layer that makes the whole system work!</p>
