Google Compute Engine Region Disk IAM

google_compute_region_disk_iam (Terraform)

The Region Disk IAM in Compute Engine can be configured in Terraform with the resource name google_compute_region_disk_iam. The following sections describe how to use the resource and its parameters.

Example Usage from GitHub

An example could not be found in GitHub.

Parameters

The following arguments are supported:

• name - (Required) Used to find the parent resource to bind the IAM policy to

• region - (Optional) A reference to the region where the disk resides. Used to find the parent resource to bind the IAM policy to. If not specified, the value will be parsed from the identifier of the parent resource. If no region is provided in the parent identifier and no region is specified, it is taken from the provider configuration.

• project - (Optional) The ID of the project in which the resource belongs. If it is not provided, the project will be parsed from the identifier of the parent resource. If no project is provided in the parent identifier and no project is specified, the provider project is used.

• member/members - (Required) Identities that will be granted the privilege in role. Each entry can have one of the following values:

  • allUsers: A special identifier that represents anyone who is on the internet; with or without a Google account.
  • allAuthenticatedUsers: A special identifier that represents anyone who is authenticated with a Google account or a service account.
  • user:[emailid]: An email address that represents a specific Google account. For example, alice@gmail.com or joe@example.com.
  • serviceAccount:[emailid]: An email address that represents a service account. For example, my-other-app@appspot.gserviceaccount.com.
  • group:[emailid]: An email address that represents a Google group. For example, admins@example.com.
  • domain:[domain]: A G Suite domain (primary, instead of alias) name that represents all the users of that domain. For example, google.com or example.com.
  • projectOwner:projectid: Owners of the given project. For example, "projectOwner:my-example-project"
  • projectEditor:projectid: Editors of the given project. For example, "projectEditor:my-example-project"
  • projectViewer:projectid: Viewers of the given project. For example, "projectViewer:my-example-project"

• role - (Required) The role that should be applied. Only one google_compute_region_disk_iam_binding can be used per role. Note that custom roles must be of the format [projects|organizations]/[parent-name]/roles/[role-name].

• policy_data - (Required only by google_compute_region_disk_iam_policy) The policy data generated by a google_iam_policy data source.

In addition to the arguments listed above, the following computed attributes are exported:

• etag - (Computed) The etag of the IAM policy.

Explanation in Terraform Registry

Three different resources help you manage your IAM policy for Compute Engine RegionDisk. Each of these resources serves a different use case:

• google_compute_region_disk_iam_policy: Authoritative. Sets the IAM policy for the regiondisk and replaces any existing policy already attached.
• google_compute_region_disk_iam_binding: Authoritative for a given role. Updates the IAM policy to grant a role to a list of members. Other roles within the IAM policy for the regiondisk are preserved.
• google_compute_region_disk_iam_member: Non-authoritative. Updates the IAM policy to grant a role to a new member. Other members for the role for the regiondisk are preserved.

  Note: google_compute_region_disk_iam_policy cannot be used in conjunction with google_compute_region_disk_iam_binding and google_compute_region_disk_iam_member or they will fight over what your policy should be.

  Note: google_compute_region_disk_iam_binding resources can be used in conjunction with google_compute_region_disk_iam_member resources only if they do not grant privilege to the same role.

Tips: Best Practices for The Other Google Compute Engine Resources

In addition to the google_compute_disk, Google Compute Engine has the other resources that should be configured for security reasons. Please check some examples of those resources and precautions.

google_compute_disk

Ensure the encryption key for your GCE disk is stored securely

It is better to store the encryption key for your GCE disk securely. Secret Manager could be used instead.

google_compute_firewall

Ensure your VPC firewall blocks unwanted outbound traffic

It is better to block unwanted outbound traffic not to expose resources in the VPC to unwanted attacks.

google_compute_instance

Ensure appropriate service account is assigned to your GCE instance

It is better to create a custom service account for the instance and assign it.

google_compute_project_metadata

Ensure OS login for your GCE instances is enabled at project level

It is better to enable OS login for your GCE instances. Enabling OS login ensures that SSH keys used to connect to instances are mapped with IAM users, allowing centralized and automated SSH key management.

google_compute_ssl_policy

Ensure to use modern TLS protocols

It's better to adopt TLS v1.2+ instead of outdated TLS protocols.

google_compute_subnetwork

Ensure VPC flow logging is enabled

It is better to enable VPC flow logging. VPC flow logging allows us to audit traffic in your network.
