I am not sure what is the correct way to fill out the InvenTree UI, what are the correct values for "Package Name" and "Source URL". In my original bug report, I have 3 options, is the first one correct?

Package Name: "my_custom_plugin"
Source URL: "https://my-custom-domain.com/python"

[matmair]

That is a difficult question. Anything pip will resolve works - that can be a local package, an http/https repository, any number of vcs repositories.

The option you listed should work.

What is a quick way of testing this branch please, ideally through docker? Sorry, I am not very familiar with Inventree dev setup.

I saw here https://docs.inventree.org/en/latest/start/docker/#tagged-images that you can get the latest main using inventree:latest is there something quick and simple I can use in this case?

@matmair pushing this to the next release, hoping to get the 1.3.0 out soon

[matmair]

@vrzh we are not releasing docker-images for PRs; you would need a dev setup or build the branch locally; are you able to do that?
