Have an Nvidia or compatible GPU?

Copy

If you have compatible GPU

docker run -d -p 3000:8080 --gpus=all -v ollama:/root/.ollama -v open-webui:/app/backend/data --name open-webui --restart always ghcr.io/open-webui/open-webui:ollama
Copy

otherwise use the CPU

docker run -d -p 3000:8080 -v ollama:/root/.ollama -v open-webui:/app/backend/data --name open-webui --restart always ghcr.io/open-webui/open-webui:ollama
Copy

Remove the failed GPU installation if you incorrectly installed the GPU version without having a compatible GPU

docker rm open-webui
Copy

Rerun either the GPU or CPU version command above. docker run...

After installation, you can access Open WebUI at http://localhost:3000

More commands...

docker stop open-webui
docker restart open-webui
Copy

curl -fsSL https://ollama.com/install.sh | sh
Copy

You go to the website and get the model command and then goto settings in the webui and put the command in Pull a model from Ollama.com
