From the author

Deploy applications and infrastructure to Cloudflare using Workers, Pages, and related platform services. Use when the user asks to deploy, host, publish, or set up a project on Cloudflare.
— the description by OpenAI

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

Cloudflare Deploy provides a centralized framework for developers to build, host, and manage projects on Cloudflare. It covers the entire ecosystem, including serverless compute (Workers), full-stack web hosting (Pages), persistent storage (D1, R2, KV), and AI-powered agent development. The skill includes decision trees to help select the right product for specific needs, authentication guidance, and troubleshooting steps for deployment issues.

What it does

  • Provides decision trees to select the appropriate Cloudflare product for compute, storage, AI, or networking.
  • Offers guidance on authenticating with the Cloudflare platform via CLI or CI/CD.
  • Includes a comprehensive product index for quick reference to documentation.
  • Provides specific patterns and API references for building stateful AI agents using the Agents SDK.
  • Offers troubleshooting steps for network-related deployment failures.
  • Supports infrastructure-as-code integration with tools like Pulumi and Terraform.

When to use it

  • When you need to deploy, host, or publish a project to Cloudflare.
  • When you are unsure which Cloudflare service (e.g., Workers vs. Pages) best fits your application requirements.
  • When you need to build stateful, globally distributed AI agents.
  • When you encounter network errors or timeouts during the deployment process.
  • When setting up persistent storage or database solutions within the Cloudflare ecosystem.

Advantages

  • Consolidates fragmented documentation into a single, navigable resource.
  • Simplifies product selection through clear, use-case-driven decision trees.
  • Provides actionable code patterns for complex tasks like AI agent development.
  • Addresses common deployment friction points like authentication and network sandboxing.

Usage examples

“I need to deploy a full-stack web application to Cloudflare. Which service should I use?”
The agent will guide you to use Cloudflare Pages for full-stack web apps with Git-based deployments.
“How do I build an AI chat agent on Cloudflare?”
The agent will provide the Agents SDK reference, including the AIChatAgent class and examples for streaming responses and managing message history.
“My deployment is failing with a network timeout error. What should I do?”
The agent will advise you to rerun the deployment command with the sandbox_permissions=require_escalated flag to bypass network restrictions.
“How do I store relational data for my worker?”
The agent will recommend using D1 for SQLite-based relational storage or Hyperdrive for connecting to existing Postgres/MySQL databases.

Documentation by OpenAI

Cloudflare Deploy

Consolidated skill for building on the Cloudflare platform. Use decision trees below to find the right product, then load detailed references.

Prerequisites

  • When sandboxing blocks the deployment network calls, rerun with sandbox_permissions=require_escalated.

  • The deployment might take a few minutes. Use appropriate timeout values.

Authentication (Required Before Deploy)

Verify auth before wrangler deploy, wrangler pages deploy, or npm run deploy:

npx wrangler whoami    # Shows account if authenticated

Not authenticated? → references/wrangler/auth.md

  • Interactive/local: wrangler login (one-time OAuth)

  • CI/CD: Set CLOUDFLARE_API_TOKEN env var

Troubleshooting

Escalated Network Access

If deployment fails due to network issues (timeouts, DNS errors, connection resets), rerun the deploy with escalated permissions (use sandbox_permissions=require_escalated). The deploy requires escalated network access when sandbox networking blocks outbound requests.

Example guidance to the user:

The deploy needs escalated network access to deploy to Cloudflare. I can rerun the command with escalated permissions—want me to proceed?

Gotchas & Best Practices

Common Errors

"Container running indefinitely"

Cause: keepAlive: true without calling destroy() Solution: Always call destroy() when done with keepAlive containers

const sandbox = getSandbox(env.Sandbox, 'temp', { keepAlive: true });
try {
  const result = await sandbox.exec('python script.py');
  return result.stdout;
} finally {
  await sandbox.destroy();  // REQUIRED to free resources
}
"CONTAINER_NOT_READY"

Cause: Container still provisioning (first request or after sleep) Solution: Retry after 2-3s

async function execWithRetry(sandbox, cmd) {
  for (let i = 0; i < 3; i++) {
    try {
      return await sandbox.exec(cmd);
    } catch (e) {
      if (e.code === 'CONTAINER_NOT_READY') {
        await new Promise(r => setTimeout(r, 2000));
        continue;
      }
      throw e;
    }
  }
}
"Connection refused: container port not found"

Cause: Missing EXPOSE directive in Dockerfile Solution: Add EXPOSE <port> to Dockerfile (only needed for wrangler dev, production auto-exposes)

"Preview URLs not working"

Cause: Custom domain not configured, wildcard DNS missing, normalizeId not set, or proxyToSandbox() not called Solution: Check:

  1. Custom domain configured? (not .workers.dev)

  2. Wildcard DNS set up? (*.domain.com → worker.domain.com)

  3. normalizeId: true in getSandbox?

  4. proxyToSandbox() called first in fetch?

"Slow first request"

Cause: Cold start (container provisioning) Solution:

  • Use sleepAfter instead of creating new sandboxes

  • Pre-warm with cron triggers

  • Set keepAlive: true for critical sandboxes

"File not persisting"

Cause: Files in /tmp or other ephemeral paths Solution: Use /workspace for persistent files

"Bucket mounting doesn't work locally"

Cause: Bucket mounting requires FUSE, not available in wrangler dev Solution: Test bucket mounting in production only. Use mock data locally.

"Different normalizeId = different sandbox"

Cause: Changing normalizeId option changes Durable Object ID Solution: Set normalizeId consistently. normalizeId: true lowercases the ID.

// These create DIFFERENT sandboxes:
getSandbox(env.Sandbox, 'MyApp');              // DO ID: hash('MyApp')
getSandbox(env.Sandbox, 'MyApp', { normalizeId: true });  // DO ID: hash('myapp')
"Code context variables disappeared"

Cause: Container restart clears code context state Solution: Code contexts are ephemeral. Recreate context after container sleep/wake.

Performance Optimization

Sandbox ID Strategy
// ❌ BAD: New sandbox every time (slow)
const sandbox = getSandbox(env.Sandbox, `user-${Date.now()}`);

// ✅ GOOD: Reuse per user
const sandbox = getSandbox(env.Sandbox, `user-${userId}`);
Sleep & Traffic Config
// Cost-optimized
getSandbox(env.Sandbox, 'id', { sleepAfter: '30m', keepAlive: false });

// Always-on (requires destroy())
getSandbox(env.Sandbox, 'id', { keepAlive: true });
// High traffic: increase max_instances
{ "containers": [{ "class_name": "Sandbox", "max_instances": 50 }] }

Security Best Practices

Sandbox Isolation

  • Each sandbox = isolated container (filesystem, network, processes)

  • Use unique sandbox IDs per tenant for multi-tenant apps

  • Sandboxes cannot communicate directly

Input Validation
// ❌ DANGEROUS: Command injection
const result = await sandbox.exec(`python3 -c "${userCode}"`);

// ✅ SAFE: Write to file, execute file
await sandbox.writeFile('/workspace/user_code.py', userCode);
const result = await sandbox.exec('python3 /workspace/user_code.py');
Resource Limits
// Timeout long-running commands
const result = await sandbox.exec('python3 script.py', {
  timeout: 30000  // 30 seconds
});
Secrets Management
// ❌ NEVER hardcode secrets
const token = 'ghp_abc123';

// ✅ Use environment secrets
const token = env.GITHUB_TOKEN;

// Pass to sandbox via exec env
const result = await sandbox.exec('git clone ...', {
  env: { GIT_TOKEN: token }
});
Preview URL Security

Preview URLs include auto-generated tokens:

https://8080-sandbox-abc123def456.yourdomain.com

Token changes on each expose operation, preventing unauthorized access.

Performance:

  • Cold start: 2-3s when waking from sleep

  • Bucket mounting: Production only (FUSE not in dev)
