Google Cloud Bigtable Instance IAM
This page shows how to write Terraform for Cloud Bigtable Instance IAM and write them securely.
Terraform Example (google_bigtable_instance_iam)
Three different resources help you manage IAM policies on bigtable instances. Each of these resources serves a different use case:
google_bigtable_instance_iam_policy: Authoritative. Sets the IAM policy for the instance and replaces any existing policy already attached.
google_bigtable_instance_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 instance are preserved.
google_bigtable_instance_iam_member: Non-authoritative. Updates the IAM policy to grant a role to a new member. Other members for the role for the instance are preserved.
google_bigtable_instance_iam_policycannot be used in conjunction with
google_bigtable_instance_iam_memberor they will fight over what your policy should be. In addition, be careful not to accidentally unset ownership of the instance as
google_bigtable_instance_iam_policyreplaces the entire policy.
google_bigtable_instance_iam_bindingresources can be used in conjunction with
google_bigtable_instance_iam_memberresources only if they do not grant privilege to the same role.
The following arguments are supported:
instance- (Required) The name or relative resource id of the instance to manage IAM policies for.
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, email@example.com or firstname.lastname@example.org.
- serviceAccount:[emailid]: An email address that represents a service account. For example, email@example.com.
- group:[emailid]: An email address that represents a Google group. For example, firstname.lastname@example.org.
- 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.
role- (Required) The role that should be applied. Only one
google_bigtable_instance_iam_bindingcan be used per role. Note that custom roles must be of the format
[projects|organizations]/[parent-name]/roles/[role-name]. Read more about roles here.
policy_data- (Required) The policy data generated by a
project- (Optional) The project in which the instance belongs. If it is not provided, Terraform will use the provider default.
In addition to the arguments listed above, the following computed attributes are exported:
etag- (Computed) The etag of the instances's IAM policy.
