You picked just the third minor concern I had, and the one that is indeed quite theoretical. I just feel safer when my cluster runs the same version of the image, but yeah, generally it won’t be an issue.
I think we should primarily stick to two other concerns I raised: 1. HA assumption 2. cluster degradation for a non negligible time.
