Add a podman guide for using quadlet files

[madscientist16]

I think it would be nice to have a guide with example quadlet files for people using podman.

Here's some examples based on the quadlet files I use to run komga and komf.

komga.pod

# Run komga and komf in a pod to make networking easier when running as rootless. 
# Komf can communicate with komga using localhost:25600 when both are running inside the same pod.

[Pod]
# Komf
PublishPort=8085:8085
# Komga
PublishPort=25600:25600

komga.container

[Unit]
Description=Komga - Media server for comics & mangas

[Container]
## General
# AutoUpdate=registry allows this container to be updated using podman auto-update command
AutoUpdate=registry
Image=docker.io/gotson/komga:latest
Pod=komga.pod

## Volumes
# %h is a shortcut for the home directory 
Volume=%h/Server/komga-pod/komga:/config
Volume=%h/Documents/Books:/data

## Environment Variables
Environment="TZ=Your/Timezone"
Environment="JAVA_TOOL_OPTIONS=-Xmx4g"

[Service]
SuccessExitStatus=0 143

See this post for the reason for adding 143 as a success exit code

komf.container

[Unit]
Description=Komf - Komga & Kavita Metadata Fetcher
After=komga.service

[Container]
# General
AutoUpdate=registry
Image=docker.io/sndxr/komf:latest
Pod=komga.pod

# Volumes
Volume=%h/Server/komga-pod/komf:/config

# Environment Variables
Environment="TZ=Your/Timezone"
Environment="KOMF_KOMGA_BASE_URI=http://localhost:25600"
Environment="[email protected]"
Environment="JAVA_TOOL_OPTIONS=-XX:+UnlockExperimentalVMOptions -XX:+UseShenandoahGC -XX:ShenandoahGCHeuristics=compact -XX:ShenandoahGuaranteedGCInterval=3600000 -XX:TrimNativeHeapInterval=3600000"
# See link below on how to create podman secrets.
Secret=komga_password,type=env,target=KOMF_KOMGA_PASSWORD

[Service]
# Add 143 for the same reason as komga
SuccessExitStatus=0 143

See this page for how to create podman secrets.

I have all three files above in ~/.config/containers/systemd/komga directory. Then I run systemctl --user daemon-reload to generate the systemd services from the quadlet files. After that I just start the komga-pod.service with systemctl --user start komga-pod.service. If I wanted to start the komga pod when I boot up the server I could add the following to komga.pod

[Install]
WantedBy=default.target

Better open at https://github.com/gotson/komga-website

It says "please open issues on the main repo" on the readme file for komga-website that's why I didn't open an issue there.
