How to Deploy Ollama & Open WebUI on Cloud VPS (Complete Guide)
Production guide to self-host Ollama local LLM inference and Open WebUI with Docker Compose, AMD AVX-512 multithreaded compute, automatic Caddy SSL reverse proxy, and document RAG with nomic embeddings.
Verify CPU AVX-512 Acceleration & System Architecture
Quantized LLMs via llama.cpp execute vector matrix multiplications efficiently when AVX-512 flags are enabled. Connect to your NodexVPS VPS and verify hardware flags.
Install Docker Engine & Compose V2 Plugin
Deploy the official Docker repository to enable containerized Ollama and Open WebUI services with automatic restarts.
Deploy Ollama & Open WebUI with Docker Compose
Create an isolated project directory and docker-compose.yml file mounting persistent model caches and WebUI database storage.
Pull High-Performance Models (DeepSeek-R1, Llama 3.3, Qwen 2.5)
Download the latest reasoning and chat models directly into your persistent GGUF storage volume.
Configure Document RAG & Knowledge Base Uploads
In Open WebUI, navigate to Workspace -> Knowledge. Upload enterprise PDFs, CSVs, or documentation. Open WebUI uses your co-located nomic-embed-text embedding model to perform semantic retrieval without sending text to external vector APIs.
Secure with Caddy Reverse Proxy & Automatic Let's Encrypt SSL
Expose Open WebUI over public HTTPS (port 443) using Caddy with zero manual certbot renewal hassle.
Expose OpenAI-Compatible API for External IDEs & Agent Swarms
Connect Cursor IDE, Continue.dev, Claude Code, or CrewAI agents to your private VPS using the standard /v1 endpoint.
