Question

Is there a clever way to determine why Pulumi might want to replace an object when re running `pulumi up`

`pulumi up diff` provides some detail but doesn t make it clear why something is being replaced

hallowed-australia-10473 · Answer

and it doesn t work if the thing Pulumi wants to replace is protected from deletion and it s a replace on change thing

ah that s the command I was looking for then you need to find which part of the diff is causing the replacement If it s a genuine diff and the property requires the resource to be replaced there s no way around it unfortunately

Hi Jack on the registry site you can check for every property if it would trigger a recreation of the resource
