Programmatically install custom themes and application

[Sushri]

Hello Everyone, 

We are using (Invision Community v4.2.3), where we install the custom application and theme using the admin console in GUI Mode. Now I have a scenario, where I need to host the application using Docker images, so manual installation becomes an overhead where I need to build the image only after doing the installation and can not automate the whole process. 

 

Is there anyone who has overcome the situation and can point out some solution ( right CI/CD process). Is there any PHP script which can be used to install the application & theme, programmatically. I work for the administration of the forum and wanted to know more about available options before reaching my development team for developing any such solution.
