Podman instructions need updated

[youainti]

The instructions to setup/use podman are out of date. In most cases now, you should be running podman through quadlet/systemd files. I have an example that I got working (using the podlet tool) under podman 4.9.5 on OpenSUSE.

If you are going to install it as a user, then you would put this in ~/.config/containers/systemd/open-webui.container

[Unit]
Description=Open-WebUI container

[Container]
AutoUpdate=registry
ContainerName=open-webui
Environment=OLLAMA_BASE_URL=http://ollama.local:11434 ANONYMIZED_TELEMETRY=False
Image=ghcr.io/open-webui/open-webui:main
Network=slirp4netns:allow_host_loopback=true
PodmanArgs=--add-host ollama.local:10.0.2.2
PublishPort=127.0.0.1:3000:8080
Volume=open-webui:/app/backend/data

[Service]
#restart rules
Restart=on-failure
RestartSec=30s
StartLimitInterval=5min
StartLimitBurst=3

[Install]
#start on boot
WantedBy=default.target

To start things, you would then run:

# this generates
 systemctl --user daemon-reload

# Verify that the quadlet file has been recognized properly
systemctl --user list-unit-files | grep open-webui
systemctl --user list-units | grep open-webui

# start the container/service
systemctl --user start open-webui

Where should I put this in the documents?
