Selfhosted

Sure thing, I'll edit this reply when I get back to my computer. Just note that I also have a tailscale and nginx container in the pod which are not necessary.

You'll see my nginx config which reverse proxies to the port the service is running on. On public servers I have another nginx running with SSL that proxies to the port I map the pod's port 80 to.

I usually run my pods as an unpriviledged user with loginctl enable-linger which starts the enabled systemctl --user services on boot.

All that being said I haven't publically exposed linkwarden yet, mainly because it's the second most resource intensive service I run and I have all my public stuff on a shitty vps.

Edit: My opsec is so bad hahaha

Edit2: I just realized the caps I gave were to the tailscale container, not the linkwarden container. Linkwarden can run with no caps :)

I added the tailscale stuff back

I also have a little helper script you might like

copy.sh:

#!/bin/bash

SYSTEMD_DIRECTORY="${HOME}/.config/containers/systemd"
POD_NAME="linkwarden-pod"

mkdir -p "$SYSTEMD_DIRECTORY"
cp "${POD_NAME}".{kube,yml} "${SYSTEMD_DIRECTORY}"/

systemctl --user daemon-reload
