Description

Enabling Compute Engine OS Login for a project ensures that SSH keys used to access instances are mapped to IAM users. If access is revoked for an IAM user, associated SSH keys are revoked as well. This streamlines handling compromised SSH key pairs and the process for revoking access.

How to fix?

Set metadata.enable-oslogin attribute to true.

Example Configurations

resource "google_compute_project_metadata" "allowed" {
  metadata = {
    "enable-oslogin" = true
  }
}

resource "google_compute_project_metadata_item" "allowed_item" {
  key   = "enable-oslogin"
  value = true
}
