Updating Instance Templates

Hi everyone

I am playing around with creating instance templates and was wondering how an existing project, using an instance template file, will be updated if the templates project is updated?

Example: I create an instance template project with a dockerfile section. I then specify to use openjdk-8 images in all the dockerfiles. Then I create my own project called my java project A, and I use the Create new file feature, where I select the Dockerfile template. All good so far.

Then we upgrade the instance template to now use openjdk-11. How will my java project A dockerfile be updated to use the new version that is in the templates directory?

TIA for any help!
