Is there a way to tell Pulumi to skip deleting some resources during destroy? I am looking for something like a “retention policy”, to tell Pulumi whether it should delete or retain (ignore) a resource on destroy.

You can use the

--target

to specify which resources you want to destroy. You can't say "destroy everything except these resources"

Another workaround is removing the resource from Pulumi state, running pulumi destroy, and importing that resource back into state

I asked a similar question: https://pulumi-community.slack.com/archives/C84L4E3N1/p1621888009237200

OK, thanks. So basically the answer is no 🙂.

That was my surmising as well 🙂
