this is AWS telling you that there's already an EC2 instance with this IP address in use, this isn't a Pulumi error

01/04/2022, 5:33 PMHi @billowy-army-68599 thx for reply, any advice how to solve it, i try to change instance type, and issue command “pulumi up” and getting this error, or should i always destroy infrastructure before update it?

01/04/2022, 8:04 PMIf you're setting a fixed IP address yourself, then you'll need to set the deleteBeforeReplace opt to true. If you're not, then you'll need to find out why there's a clash; normally, this wouldn't happen.

01/04/2022, 8:06 PMPulumi intentionally creates replacement resources before deleting the original ones (more info here: https://www.pulumi.com/docs/troubleshooting/faq/#why-do-resource-names-have-random-hex-character-suffixes). So for resources that have properties that must be unique (such as IP addresses on a single subnet), you either have to change the behaviour, or change your logic.
