[Quadlet] Separating caddy ang php-fpm

[rEnr3n]

I'm trying to migrate wallabag to quadlet. Before quadlet, I had 5 systemd services.

1. Pod
2. Wallabag
   I manually replaced ExecStart to use podman create. Type=oneshot and RemainAfterExit=yes were added too. My Containerfile looked something like this:

FROM docker.io/archlinux AS build
RUN pacman --quiet --noconfirm --needed -Syu wallabag

FROM scratch
COPY --from=build /usr/share/wallabag /

3. Postgresql
4. Caddy
   Caddy needs access to wallabag files so they are mounted like this:
   --mount type=image,src=wallabag,dst=/usr/share/wallabag,rw=true
--volumes-from wallabag for the bind mounts
5. Php-fpm
   Php also need access to the files so they're also mounted here:
   --mount type=image,src=wallabag,dst=/usr/share/wallabag,rw=true
--volumes-from wallabag for the bind mounts

---

Now my dilemma is running wallabag container. I don't see any option in quadlet that allows me to use podman create instead of podman run. The container doesn't have a sleep command I can use to keep it running.

So I tried to merge wallabag and php-fpm containers into one but realized caddy needs access to the files too. I would need to install caddy, php-fpm and wallabag into one container. I didn't like that idea. I tried to create a systemd drop-in file like this:

[Service]
ExecStart=
ExecStart=podman create ...

But t doesn't remove the ExecStart=podman run ... line.

I'v ran out of ideas on how to proceed with this. Any help would be appreciated.

Hi,

I'm trying to understand the use case. IIUC the sole purpose of the wallabag service is building the image. Am I correct?

If yes, what I think you could possibly do is manually write this specific service (as you did) and set it as a dependency for the PHP and Caddy ones.

I did have a vision of expanding the .image files to also build images (and not only pull them). But, I didn't get around to implementing it.

That was my setup. The problem is the image contains only files that comprise the entire wallabag webapp. There is no sleep or php command there so I can't keep it running.

My current workaround is to download the webapp on my host and mount it on php-fpm and caddy containers. I'm not sure if I like this route since I'm still figuring out how to automate this.
