4. Getting Started with Mainflux
Step 1: Install Dependencies
- Ensure you have Docker and Docker Compose installed on your system.
- Optionally, set up Kubernetes for production-grade deployments.
Step 2: Clone the Repository
bash
git clone https://github.com/mainflux/mainflux.git
cd mainflux
Step 3: Start Mainflux
Use Docker Compose to start the platform:
bash
docker-compose up -d
Step 4: Access the Dashboard
- The Mainflux UI is available at
http://localhost:3000. - Log in with default credentials (if applicable) or create a new account.
