If 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

Pulumi 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
