ForgeMindAI - Docker Compose & n8n Workflow

This repository is part of the ForgeMindAI YouTube channel, where we explore practical AI automation tools and workflows. Here, you'll find a ready-to-use Docker Compose setup to kickstart your own AI-powered automation.

N8N starter Docker Environment

This repository provides a Docker Compose setup to orchestrate the following services:

• n8n (workflow automation tool)
• PostgreSQL (as n8n's database)
• Qdrant (vector search engine for AI-related tasks)
• n8n-import (a one-time service to import workflows and credentials)

---

🧱 Services

1. n8n

• The core automation platform.
• Exposes port 5678.
• Mounts volumes for persistent storage, workflow/credential backups, and shared data.
• Depends on:
  • postgres (healthy)
  • n8n-import (successful completion)

2. postgres

• Lightweight PostgreSQL database (v16-alpine).
• Stores data in the postgres_storage volume.
• Includes a health check to ensure it's ready before other services connect.

3. n8n-import

• A short-lived container to import existing credentials and workflows from the /n8n/backup directory.
• Uses the same configuration as the main n8n service.
• Runs once, before the main n8n container starts.

4. qdrant

• A high-performance vector database used for semantic search or AI-powered features.
• Exposes port 6333 for API access.
• Persists data in qdrant_storage.

⚙️ Environment Variables

Make sure to define the following variables in a .env file or your shell environment:

• POSTGRES_USER
• POSTGRES_PASSWORD
• POSTGRES_DB
• N8N_ENCRYPTION_KEY
• N8N_USER_MANAGEMENT_JWT_SECRET

---

🚀 Usage

1. Create your .env file with the required variables.
2. Place your credentials and workflows in n8n/backup.
3. Run the stack:

   docker-compose up -d
   

Steps to bring up container

1. Copy the docker compose to seperate directory.
2. use docker compose up -d to start the container.
3. Ensure you have docker command line installed.
4. use docker compose down to stop the container.
