Deploy and Host Ollama API on Railway

Ollama API enables you to run large language models and expose them via authenticated HTTP endpoints. This template provides a production-ready deployment with proxy authentication and customizable model selection through environment variables, making it easy to serve models like Llama, Mistral, and CodeLlama at scale.

About Hosting Ollama API

Hosting Ollama API involves containerizing the Ollama runtime environment and exposing its REST endpoints through a secure proxy layer. This deployment handles model downloading, and request routing. The template includes authentication middleware to secure your API endpoints, automatic model installation based on configuration, and horizontal scaling capabilities to handle varying workloads efficiently.

Common Use Cases

Private AI Chatbots: Deploy custom language models for internal company use without sending data to external APIs
Content Generation Services: Power content creation tools, writing assistants, and automated documentation systems
Code Completion APIs: Serve specialized code models for IDE integrations and developer tools
Research and Experimentation: Host multiple model variants for A/B testing and model comparison studies

Dependencies for Ollama API Hosting

Ollama Runtime: Core engine for running and serving large language models
Authentication Proxy: Middleware layer for securing API access and request validation

Deployment Dependencies

Implementation Details

The template uses a customizable MODEL service variable to specify which model to install:

# Set your desired model
MODEL=llama2:7b

# Or use other popular models
MODEL=mistral:latest
MODEL=codellama:13b

The authentication proxy validates requests before forwarding to Ollama, ensuring secure access to your deployed models while maintaining the standard Ollama API interface.
