普鲁米 SDK SQL 删除保护不起作用

Question

I have provisioned SQL (PostrgresSQL) on GCP cloud using Pulumi SDK (Go). I have set deletionProtection as true - but checking GCP console I can see the SQL is not protected. I was able to delete the instance using console by that breaking Pulumi state.

Google cloud doesn't have an API mechanism to prevent deletion of SQL database, only for virtual machines.

If you look at the description of the deletionProtection property is says the following:

Whether or not to allow the provider to destroy the instance. Unless this field is set to false in state, a destroy or update command that deletes the instance will fail.

Deletion protection is a Pulumi state only operation. It isn't actually modifying the Database in Google cloud at all, because Google doesn't support it.

You will not be able to prevent deletion of a Google Cloud SQL instance outside of Pulumi
