Hello, this does not seem to work at all.
I cannot even render the template.

Image is recommended to use a versioned tag and not latest.
Port is static so users cannot edit it. Also it would be nice if internal container port is also changed via env variable to match the external one.
So users can also use host network without chances of port conflicts.

certificate is not used anywhere

container name is different in the labels section than the one that is used to create the container.

values are statically set in the compose file instead of using the values file.

For readme I'd suggest having a small description like the rest of the apps,
and have a link to your github for the rest. (as the rest of the apps)

app.yaml file should be the same format as the rest, as it is modified from automated tools and will create big diffs on subsequent automated PRs

questions.yaml seems to have a user/group group defined at the top but is not used anywhere.
Is the container running as root or rootless?
Based on the compose it seems to run as rootless, but uses cannot edit that. as you reference it from the consts.
