Open WebUI

Demo Environment

Development board: Jetson Orin series motherboard

SSD: 128G

Tutorial Scope

Open WebUI is an open source project that aims to provide a simple and easy-to-use user interface (UI) for managing and monitoring open source software and services.

xxxxxxxxxx
When using Open WebUI, there is a high probability that the dialogue will be unresponsive or timeout. You can try restarting Open WebUI or using the Ollama tool to run the model!

1. Environmental requirements

Host and Conda installation of Open WebUI: Node.js >= 20.10, Python = 3.11:

Tutorial demonstrates Docker installation of Open WebUI.

2. Docker construction

2.1. Official installation of Docker

If Docker is not installed, you can use the script to install Docker in one click.

• Update local package lists

xxxxxxxxxx
sudo apt update

• Upgrading installed packages

xxxxxxxxxx
sudo apt upgrade

• Download and run the script

Download the get-docker.sh file and save it in the current directory.

xxxxxxxxxx
sudo apt install curl

xxxxxxxxxx
curl -fsSL https://get.docker.com -o get-docker.sh

Run the get-docker.sh script file with sudo privileges.

xxxxxxxxxx
sudo sh get-docker.sh

2.2. Add access permissions

Add system current user access rights to Docker daemon: You can use Docker commands without using sudo command

xxxxxxxxxx
sudo usermod -aG docker $USER
newgrp docker

3. Open WebUI installation

For systems with Docker installed, you can directly enter the following command in the terminal: The image is the result of the pull

xxxxxxxxxx
docker pull ghcr.io/open-webui/open-webui:main

4. Open WebUI and run

Enter the following command in the terminal to start the specified Docker:

xxxxxxxxxx
docker run --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

After successful startup, use the following URL to access the browser:

xxxxxxxxxx
http://localhost:8080/

The same LAN can use the motherboard IP:8080 to access:

x
Assuming the motherboard IP: 192.168.2.105, we can access it through 192.168.2.105:8080

4.1. Administrator account

You need to register an account for the first time. This account is an administrator account. You can fill in the information as required!

x
Since all the contents of our mirror have been set up and tested, users can directly log in with our registered account:
Username: yahboom
Email: yahboom@163.com
Password: yahboom

4.2. Register and log in

4.3 User Interface

5. Model dialogue

Using Open WebUI for dialogue will be slower than using the Ollama tool directly, and may even cause timeout service connection failure. This is related to the memory of the Jetson motherboard and cannot be avoided!

x
Users with ideas can switch to other Linux environments to build the Ollama tool and Open WebUI tool for dialogue

5.1. Switch model

Click Select a model to select a specific model for dialogue.

x
The model pulled by ollama will be automatically added to the Open WebUI model option. Refresh the web page and the new model will appear!

5.2. Demonstration: LLaVA

The LLaVA case demonstrated requires 8G or even more than 8G to run. Users can use other cases to test the Open WebUI dialogue function!

6. Common Problems

6.1. Close Open WebUI

Close the automatically started Open WebUI.

• View the running Docker

xxxxxxxxxx
docker ps

• Close the running Docker

xxxxxxxxxx
docker stop [CONTAINER ID] # Example docker stop 5f42ee9cf784

• View the stopped container

xxxxxxxxxx
docker ps -a

• Clean up the stopped container

xxxxxxxxxx
docker rm [CONTAINER ID] # Example docker rm 5f42ee9cf784

Clean up all stopped containers:

xxxxxxxxxx
docker container prune

6.2. Common Errors

Unable to start Open WebUI

• docker: Error response from daemon: Conflict. The container name "/open-webui" is already in use by container "cfc05c84f8e38b290337e7178c76fd1c49076f94b11ed3d49d9448be72b7f20f". You have to remove (or rename) that container to be able to reuse that name.

Solution: Close Open WebUI once and restart!

Service connection timeout

• Open WebUI: Server Connection Error

Close Open WebUI once and restart, then ask again or run the model with the Ollama tool to ask questions!
