How to Install 🚀

Note

Please note that for certain Docker environments, additional configurations might be needed. If you encounter any connection issues, our detailed guide on Open WebUI Documentation is ready to assist you.

Quick Start with Docker 🐳

Important

When using Docker to install Open WebUI, make sure to include the -v open-webui:/app/backend/data in your Docker command. This step is crucial as it ensures your database is properly mounted and prevents any loss of data.

• If Ollama is on your computer, use this command:

  docker run -d -p 3000:8080 --add-host=host.docker.internal:host-gateway -v open-webui:/app/backend/data --name open-webui --restart always ghcr.io/open-webui/open-webui:main
  

• If Ollama is on a Different Server, use this command:

• To connect to Ollama on another server, change the OLLAMA_BASE_URL to the server's URL:

  docker run -d -p 3000:8080 -e OLLAMA_BASE_URL=https://example.com -v open-webui:/app/backend/data --name open-webui --restart always ghcr.io/open-webui/open-webui:main
  

• After installation, you can access Open WebUI at http://localhost:3000. Enjoy! 😄

• If you want to customize your build with additional args, use this commands:

  Note

  If you only want to use Open WebUI with Ollama included or CUDA acelleration it's recomented to use our official images with the tags :cuda or :with-ollama If you want a combination of both or more customisation options like a different embedding model and/or CUDA version you need to build the image yourself following the instructions below.

  For the build:

  docker build -t open-webui
  

  Optional build ARGS (use them in the docker build command below if needed):

  e.g.
  

  --build-arg="USE_EMBEDDING_MODEL=intfloat/multilingual-e5-large"
  

  For "intfloat/multilingual-e5-large" custom embedding model (default is all-MiniLM-L6-v2), only works with sentence transforer models. Current Leaderbord of embedding models.

  --build-arg="USE_OLLAMA=true"
  

  For including ollama in the image.

  --build-arg="USE_CUDA=true"
  

  To use CUDA exeleration for the embedding and whisper models.

  Note

  You need to install the Nvidia CUDA container toolkit on your machine to be able to set CUDA as the Docker engine. Only works with Linux - use WSL for Windows!

  --build-arg="USE_CUDA_VER=cu117"
  

  For CUDA 11 (default is CUDA 12)

  To run the image:

  • If you DID NOT use the USE_CUDA=true build ARG, use this command:

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

  • If you DID use the USE_CUDA=true build ARG, use this command:

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

  • After installation, you can access Open WebUI at http://localhost:3000. Enjoy! 😄

Open WebUI: Server Connection Error

If you're experiencing connection issues, it’s often due to the WebUI docker container not being able to reach the Ollama server at 127.0.0.1:11434 (host.docker.internal:11434) inside the container . Use the --network=host flag in your docker command to resolve this. Note that the port changes from 3000 to 8080, resulting in the link: http://localhost:8080.

Example Docker Command:

docker run -d --network=host -v open-webui:/app/backend/data -e OLLAMA_BASE_URL=http://127.0.0.1:11434 --name open-webui --restart always ghcr.io/open-webui/open-webui:main

Other Installation Methods

We offer various installation alternatives, including non-Docker methods, Docker Compose, Kustomize, and Helm. Visit our Open WebUI Documentation or join our Discord community for comprehensive guidance.

Troubleshooting

Encountering connection issues? Our Open WebUI Documentation has got you covered. For further assistance and to join our vibrant community, visit the Open WebUI Discord.

Keeping Your Docker Installation Up-to-Date

In case you want to update your local Docker installation to the latest version, you can do it with Watchtower:

docker run --rm --volume /var/run/docker.sock:/var/run/docker.sock containrrr/watchtower --run-once open-webui

In the last part of the command, replace open-webui with your container name if it is different.
