exit status 2
make: *** [Makefile:103: run] Error 1
This occurs because resource IDs are often accessed via pointers, which are not guaranteed to be available at runtime.
Proposed solution
Option 1:
Update the operator code to manage changes in both product and account references. This include detecting incoming changes, deleting the old application, and creating a new one.
Option 2:
Mark both the account and product references as immutable, meaning the field cannot be changed once set.
How to reproduce:
- Create a DeveloperUserCR, a DeveloperAccountCR, 2 Products and an ApplicationCR
- Wait for operator to sync all CR's, and check the assigned applicationID of application
- Update ApplicationCR to reference the other product
- Check operator log for exception
