Help for new app packaging : 13ft [12ft.io alternative] - bypass paywalls

I configured a systemd service (and registration into yunohost web admin interface), but I’m unsure how to do it properly. Right now the command is python 3 /var/www/[app path]/init.py and that’s it.

@Aleks

you will usually want to use gunicorn which is a small piece of software that creates a bunch of workers for the app such that it’s not a single process handling all the request (imagine only 1 waiter/waitress/cook in a 1000-person restaurant)

I don’t know if it’s needed in that case, it’s a very simple and lightweight app, and I believe it won’t be used that much.
Is it simple to do ? What’s the drawbacks ?

@Aleks

Not sure why you’d want to stop it ?

When I uninstall it ?
And also I think it’s good that users have the control to shut it down.

@Aleks

Maybe you’re referring to having the systemd service listed in the “Services” section of the webadmin. For this you can have a look at the call to yunohost service add in the app install script

Already done, thanks :), it’s very simple with the handler and the default example

@Aleks

Usually Python apps use what’s called virtualenv to properly separate all their dependencies from the rest of the system

Oh yeah, I haven’t deployed a python app for so long that I forgot about that

@Aleks

This implies the app provides a requirements.txt as part of its source to list its dependencies

Great, thanks for the tip. What the syntax ? Just flask ?

@Aleks

correct example in pepettes : pepettes_ynh/install at master · YunoHost-Apps/pepettes_ynh · GitHub

Thanks for pointing this, very appreciated, I was a bit lost about how to do it properly the yunohost way
