Manage GCP BigQuery Data Policy IAM Bindings

The gcp:bigquery/datapolicyv2DataPolicyIamBinding:Datapolicyv2DataPolicyIamBinding resource, part of the Pulumi GCP provider, manages IAM role bindings for BigQuery data policies, controlling which identities can access policy-protected data. This guide focuses on two capabilities: granting roles to multiple members and adding individual members incrementally.

IAM bindings reference existing BigQuery data policies and require valid role names. The examples are intentionally small. Combine them with your own data policy resources and organizational identity structure.

Grant a role to multiple members at once

When managing data policy access, you often need to grant the same role to multiple users, service accounts, or groups simultaneously.

import * as pulumi from "@pulumi/pulumi";
import * as gcp from "@pulumi/gcp";

const binding = new gcp.bigquery.Datapolicyv2DataPolicyIamBinding("binding", {
    project: basicDataPolicy.project,
    location: basicDataPolicy.location,
    dataPolicyId: basicDataPolicy.dataPolicyId,
    role: "roles/viewer",
    members: ["user:jane@example.com"],
});

import pulumi
import pulumi_gcp as gcp

binding = gcp.bigquery.Datapolicyv2DataPolicyIamBinding("binding",
    project=basic_data_policy["project"],
    location=basic_data_policy["location"],
    data_policy_id=basic_data_policy["dataPolicyId"],
    role="roles/viewer",
    members=["user:jane@example.com"])

package main

import (
	"github.com/pulumi/pulumi-gcp/sdk/v9/go/gcp/bigquery"
	"github.com/pulumi/pulumi/sdk/v3/go/pulumi"
)

func main() {
	pulumi.Run(func(ctx *pulumi.Context) error {
		_, err := bigquery.NewDatapolicyv2DataPolicyIamBinding(ctx, "binding", &bigquery.Datapolicyv2DataPolicyIamBindingArgs{
			Project:      pulumi.Any(basicDataPolicy.Project),
			Location:     pulumi.Any(basicDataPolicy.Location),
			DataPolicyId: pulumi.Any(basicDataPolicy.DataPolicyId),
			Role:         pulumi.String("roles/viewer"),
			Members: pulumi.StringArray{
				pulumi.String("user:jane@example.com"),
			},
		})
		if err != nil {
			return err
		}
		return nil
	})
}

{
    var binding = new Gcp.BigQuery.Datapolicyv2DataPolicyIamBinding("binding", new()
    {
        Project = basicDataPolicy.Project,
        Location = basicDataPolicy.Location,
        DataPolicyId = basicDataPolicy.DataPolicyId,
        Role = "roles/viewer",
        Members = new[]
        {
            "user:jane@example.com",
        },
    });

    properties:

      dataPolicyId: ${basicDataPolicy.dataPolicyId}
      role: roles/viewer
      members:
        - user:jane@example.com

The Binding resource is authoritative for the specified role: it replaces all members for that role on the data policy. The members array accepts various identity formats including user emails, service accounts, groups, and domain-wide grants. The dataPolicyId and location properties identify which data policy receives the binding.

Add a single member to a role incrementally

As access control evolves, you may need to add individual users without affecting existing role assignments.

import * as pulumi from "@pulumi/pulumi";
import * as gcp from "@pulumi/gcp";

const member = new gcp.bigquery.Datapolicyv2DataPolicyIamMember("member", {
    project: basicDataPolicy.project,
    location: basicDataPolicy.location,
    dataPolicyId: basicDataPolicy.dataPolicyId,

    member: "user:jane@example.com",
});

import pulumi_gcp as gcp

member = gcp.bigquery.Datapolicyv2DataPolicyIamMember("member",
    project=basic_data_policy["project"],
    location=basic_data_policy["location"],
    data_policy_id=basic_data_policy["dataPolicyId"],
    role="roles/viewer",
    member="user:jane@example.com")

package main

		})
		if err != nil {
			return err
		}
		return nil
	})
}

return await Deployment.RunAsync(() =>

    var member = new Gcp.BigQuery.Datapolicyv2DataPolicyIamMember("member", new()

        Project = basicDataPolicy.Project,
        Location = basicDataPolicy.Location,
        DataPolicyId = basicDataPolicy.DataPolicyId,

      dataPolicyId: ${basicDataPolicy.dataPolicyId}
      role: roles/viewer
      member: user:jane@example.com

The Member resource adds one identity to a role while preserving other members already assigned to that role. Use member (singular) instead of members (array) to specify the single identity. This approach works well when access grants happen incrementally rather than as batch operations.

Beyond these examples

These snippets focus on specific IAM binding features: role-based access control and batch and incremental member assignment. They’re intentionally minimal rather than full access control configurations.

The examples reference pre-existing infrastructure such as BigQuery data policies (dataPolicyId references). They focus on configuring IAM bindings rather than creating the underlying data policies.

To keep things focused, common IAM patterns are omitted, including:

Conditional IAM bindings (condition property)
Policy resource for full IAM policy replacement
Custom role definitions and formatting
Federated identity configuration

These omissions are intentional: the goal is to illustrate how each IAM binding feature is wired, not provide drop-in access control modules. See the Datapolicyv2DataPolicyIamBinding resource reference for all available configuration options.

Frequently Asked Questions

Resource Selection & Conflicts

What's the difference between IamPolicy, IamBinding, and IamMember resources?

Datapolicyv2DataPolicyIamPolicy is authoritative and replaces the entire IAM policy. Datapolicyv2DataPolicyIamBinding is authoritative for a specific role, preserving other roles. Datapolicyv2DataPolicyIamMember is non-authoritative, adding a single member while preserving other members for that role.

Can I use IamPolicy with IamBinding or IamMember resources?

No, Datapolicyv2DataPolicyIamPolicy cannot be used with Datapolicyv2DataPolicyIamBinding or Datapolicyv2DataPolicyIamMember because they will conflict over the policy state.

Can I use IamBinding and IamMember together?

Yes, but only if they grant different roles. Using both for the same role will cause conflicts.

Configuration & Identity Formats

What member identity formats are supported?

The members array accepts multiple formats:

allUsers or allAuthenticatedUsers for public/authenticated access
user:{email}, serviceAccount:{email}, group:{email} for specific identities
domain:{domain} for G Suite domains
projectOwner:projectid, projectEditor:projectid, projectViewer:projectid for project roles
Federated identities using principal:// format (see Principal identifiers documentation)

How do I specify custom IAM roles?

Custom roles must use the format [projects|organizations]/{parent-name}/roles/{role-name}. For example, projects/my-project/roles/my-custom-role or organizations/my-org/roles/my-custom-role.

Import & Advanced Usage

How do I import an existing IAM binding?

Use space-delimited identifiers with the resource path and role:

pulumi import gcp:bigquery/datapolicyv2DataPolicyIamBinding:Datapolicyv2DataPolicyIamBinding editor "projects/{{project}}/locations/{{location}}/dataPolicies/{{data_policy_id}} roles/viewer"
