Getting Started

SQLite (Default)

1. Create a .env file with authentication credentials:

   N8N_BASIC_AUTH_USER=admin
   N8N_BASIC_AUTH_PASSWORD=your-secure-password
   

2. Start the service:

   docker compose up -d
   

3. Access n8n at http://localhost:5678

PostgreSQL

1. Create a .env file with authentication and database credentials:

   N8N_BASIC_AUTH_USER=admin
   N8N_BASIC_AUTH_PASSWORD=your-secure-password
   DB_TYPE=postgresdb
   DB_POSTGRESDB_PASSWORD=your-db-password
   

2. Start the service with PostgreSQL profile:

   docker compose --profile postgres up -d
   

3. Access n8n at http://localhost:5678
