Pulumi has enhanced its capability to import existing cloud infrastructure resources, allowing users to manage them within the Pulumi framework regardless of their original provisioning method. With the introduction of the `pulumi import` command in version 2.12.0, users can import resources such as AWS S3 buckets and EC2 instances into the Pulumi state, generating the necessary code for integration into a Pulumi program in various programming languages. Resources imported are marked as protected by default to prevent accidental deletion, ensuring they remain intact unless the protection is manually removed. This feature supports bulk imports, making it easier for users to transition multiple resources into Pulumi management, and it is accompanied by comprehensive documentation and examples for ease of use.
