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

# download the model
`ollama pull codellama:7b`


# if ollama server and interface must be on the same server, here is the docker command to run 

`sudo docker run -d -p 3000:8080 -e OLLAMA_API_BASE_URL=http://127.0.0.1:11434/api --network=host -v open-webui:/app/backend/data --name open-webui --restart always ghcr.io/open-webui/open-webui:main`


# now go to `htp://<ip>:8080` then create your account, then select the model you wish to interact with

every model will be detected by API, just pull the model you want : https://ollama.com/library

it does not find the models....

Edit the file /etc/systemd/system/ollama.service. and add and below after existing Environment settings
Environment="OLLAMA_HOST=0.0.0.0"
and restart ollama service. It will detect models
