n8n Workflow Deployment

Goal

Create and deploy visual automation workflows using n8n. Connect any APIs, trigger via webhooks/schedule, no code needed for basic flows.

When to Use

• Multi-step workflows (Form → CRM → Email → Slack → Sheet)
• Webhook-driven automation (receive events, process, respond)
• Visual workflows students/clients can understand without code
• Connecting 400+ integrations via built-in nodes

Prerequisites

• n8n running (self-hosted on VPS or n8n Cloud)
• For self-hosted: Docker installed on VPS

Self-Hosted Setup (Docker Compose)

1. Create docker-compose.yml on your VPS

version: '3.8'
services:
  n8n:
    image: n8nio/n8n
    ports:
      - "5678:5678"
    environment:
      - N8N_BASIC_AUTH_ACTIVE=true
      - N8N_BASIC_AUTH_USER=admin
      - N8N_BASIC_AUTH_PASSWORD=changeme
      - N8N_HOST=your-domain.com
      - N8N_PROTOCOL=https
      - WEBHOOK_URL=https://your-domain.com/
    volumes:
      - n8n_data:/home/node/.n8n
    restart: unless-stopped

volumes:
  n8n_data:

2. Start n8n

docker-compose up -d

3. Access n8n

Open http://your-vps-ip:5678 or https://your-domain.com

Creating a Workflow

Via n8n UI (Visual)

1. Open n8n dashboard
2. Click "New Workflow"
3. Add trigger node (Webhook, Schedule, or Manual)
4. Add processing nodes (HTTP Request, Code, IF, etc.)
5. Connect nodes by dragging edges
6. Click "Activate" to make it live

Via JSON Import

1. Create a workflow JSON file
2. In n8n: Workflows → Import → paste JSON

Example: Social Media Post Workflow

{
  "name": "Daily Social Media Post",
  "nodes": [
    {
      "name": "Schedule Trigger",
      "type": "n8n-nodes-base.scheduleTrigger",
      "parameters": {
        "rule": {"interval": [{"field": "hours", "hoursInterval": 24}]}
      },
      "position": [250, 300]
    },
    {
      "name": "Generate Content",
      "type": "n8n-nodes-base.httpRequest",
      "parameters": {
        "url": "https://api.euron.one/api/v1/euri/chat/completions",
        "method": "POST",
        "headers": {"Authorization": "Bearer {{$env.EURI_API_KEY}}"},
        "body": {
          "model": "gpt-4o-mini",
          "messages": [{"role": "user", "content": "Write a LinkedIn post about AI automation"}]
        }
      },
      "position": [450, 300]
    },
    {
      "name": "Post to LinkedIn",
      "type": "n8n-nodes-base.httpRequest",
      "parameters": {
        "url": "https://api.linkedin.com/rest/posts",
        "method": "POST",
        "headers": {
          "Authorization": "Bearer {{$env.LINKEDIN_ACCESS_TOKEN}}",
          "LinkedIn-Version": "202603"
        },
        "body": "={{JSON.stringify({author: 'urn:li:person:' + $env.LINKEDIN_PERSON_URN, lifecycleState: 'PUBLISHED', visibility: 'PUBLIC', commentary: $json.choices[0].message.content, distribution: {feedDistribution: 'MAIN_FEED'}})}}"
      },
      "position": [650, 300]
    }
  ],
  "connections": {
    "Schedule Trigger": {"main": [[{"node": "Generate Content", "type": "main", "index": 0}]]},
    "Generate Content": {"main": [[{"node": "Post to LinkedIn", "type": "main", "index": 0}]]}
  }
}

Free Hosting Options

Option	Cost	Setup
Oracle Cloud Free VPS	$0 forever	Docker Compose on ARM VM
PikaPods	~$3.80/mo	Managed, zero DevOps
Hostinger VPS	~$5/mo	1-click n8n template
DigitalOcean	$6/mo	Docker Compose on droplet

Gotchas

1. Webhook URLs change if n8n restarts (self-hosted without domain). Use Cloudflare Tunnel for stable URLs.
2. n8n stores data in SQLite by default — switch to PostgreSQL for production.
3. Environment variables — set in docker-compose.yml, not in workflow nodes.
4. Activate workflows — creating a workflow doesn't start it. Click the toggle.
5. Error handling — always add an Error Trigger node to catch failures.
