Install / Update

Hi everyone,
Currently, I am working on installing erpnextswiss on Docker.
It seems there are different methods for installing additional apps.

Installing ERPNext with the default pwd.yml works fine.
Installing other apps like Wiki, Payments, etc., works well via both the frontend and backend containers.

Can anyone guide me on the correct way to install erpnextswiss? The installation instructions provided don’t seem to work for me.
Here’s the link to the erpnextswiss installation guide.
easy install script is no option, since it is no longer in developmend.

I was able to install wiki and payment by adding them to the apps.json.
My problem still exists with erpnextswiss.
in my apps.json i have added the following for erpnextswiss
{
“url”: “GitHub - libracore/erpnextswiss: ERPNext application for Switzerland-specific use cases”,
“branch”: “v2025”
},

and in my .yml file i have added the following for erpnextswiss (not working) and as example the wiki (working)
–install-app erpnextswiss --install-app wiki --set-default frontend;

Did anyone ever sucessfulli install erpnextswiss?

If this is needed you also need to fork the build file and add it to the base layer. frappe_docker/images/custom/Containerfile at e642a804ca9d0d096e514becca91e7ae0a2fada7 · frappe/frappe_docker · GitHub
