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.

🔄 Volumes

Name Purpose
n8n_storage Stores n8n's internal configuration and workflow data
postgres_storage Stores PostgreSQL data
qdrant_storage Stores Qdrant data

🌐 Networks

Name Purpose
demo Shared network between all services

⚙️ 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.
