08/23/2019, 2:58 PMAre you saying their API doesn’t allow for what you can do in the console? If so, that’s quite stupid of them.

08/23/2019, 5:07 PM@cool-egg-852 I’m not an expert—just, generally, my understanding is that a property is not marked for replacement unless we have to replace the resource. perhaps @stocky-spoon-28903 @broad-dog-22463 have more information?

Which resource is this specifically? There are frequently either cloud provider issues or upstream provider issues that lead to overly conservative treatments of replacement requirements - but would have to look into a specific resource to be sure.

08/23/2019, 7:31 PMIt’s not trying to replace the DatabaseInstance, at least not anymore. Instead, it’s trying to replace the user and the database
cool-egg-852
08/23/2019, 7:31 PMThis doesn’t make any sense. The instance isn’t being recreated, but at minimum the previous is saying it will do a create-replacement on the user and Database.

08/23/2019, 7:51 PMI’m testing this out. I’m beginning to think this is based upon the limitation of the preview. The preview seems to assume changes are required that are not actually required when executing.

08/23/2019, 7:52 PMThis same thing scared me a few minutes ago when updating a configMap. It caused the deployment to show it was going to be replaced. It was only updated in the end.

08/23/2019, 7:59 PMYep, that’s exactly what happened.
cool-egg-852
08/23/2019, 7:59 PMIs there no way to fix this? The preview should not be this off from reality.

08/28/2019, 2:49 PMI’m curious why this has gotten worse rather than better. I never experienced this previously where the diff was so off.
