Needs advice

Hi, I'm working on dockerizing a heavy Java EE application where the process of installation requires a complex process maintained by a Gradle project we've developed to install, configure and customize specific jar files to generate a runnable server application at the end for the user. I'm new to Docker. As I said, the problem is that we have got a long process to install the app. The first alternative pop into my head is to put the installer Gradle project in the docker image and manage stateful data using the writable layer (in this case, I need to add Gradle too and the writable layer will be too heavy). Any advice! Thank you

You can build these images locally or through some CICD server.

Here's an exemple with Gradle
