Manage GCP BigQuery Analytics Hub Data Exchange IAM Bindings

The gcp:bigqueryanalyticshub/dataExchangeIamBinding:DataExchangeIamBinding resource, part of the Pulumi GCP provider, manages IAM role bindings for BigQuery Analytics Hub data exchanges. This guide focuses on two capabilities: granting roles to multiple members and adding individual members incrementally.

IAM bindings control access to existing data exchanges. The DataExchangeIamBinding resource is authoritative for a given role, meaning it replaces all members assigned to that role. The examples are intentionally small. Combine them with your own data exchange resources and identity management.

Grant a role to multiple members at once

Teams managing data exchanges often need to assign the same role to multiple users or service accounts simultaneously, such as giving viewer access to an entire team.

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

const binding = new gcp.bigqueryanalyticshub.DataExchangeIamBinding("binding", {
    project: dataExchange.project,
    location: dataExchange.location,
    dataExchangeId: dataExchange.dataExchangeId,
    role: "roles/viewer",
    members: ["user:jane@example.com"],
});

import pulumi
import pulumi_gcp as gcp

binding = gcp.bigqueryanalyticshub.DataExchangeIamBinding("binding",
    project=data_exchange["project"],
    location=data_exchange["location"],
    data_exchange_id=data_exchange["dataExchangeId"],
    role="roles/viewer",
    members=["user:jane@example.com"])

package main

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

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

    {
        Project = dataExchange.Project,
        Location = dataExchange.Location,
        DataExchangeId = dataExchange.DataExchangeId,
        Role = "roles/viewer",
        Members = new[]
        {
            "user:jane@example.com",

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

The role property specifies which IAM role to grant. The members array lists all identities that should receive this role. This resource is authoritative for the specified role, so it replaces any existing member list for that role on the data exchange. The dataExchangeId, location, and project properties identify which data exchange to configure.

Add a single member to a role incrementally

When onboarding individual users or service accounts, you can add them one at a time without affecting other members who already have access.

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

const member = new gcp.bigqueryanalyticshub.DataExchangeIamMember("member", {
    project: dataExchange.project,
    location: dataExchange.location,
    dataExchangeId: dataExchange.dataExchangeId,
    role: "roles/viewer",
    member: "user:jane@example.com",
});

import pulumi
import pulumi_gcp as gcp

member = gcp.bigqueryanalyticshub.DataExchangeIamMember("member",
    project=data_exchange["project"],
    location=data_exchange["location"],
    data_exchange_id=data_exchange["dataExchangeId"],
    role="roles/viewer",
    member="user:jane@example.com")

package main

import (
	"github.com/pulumi/pulumi-gcp/sdk/v9/go/gcp/bigqueryanalyticshub"

func main() {

			Role:           pulumi.String("roles/viewer"),
			Member:         pulumi.String("user:jane@example.com"),
		})
		if err != nil {
			return err
		}
		return nil
	})
}

using System.Collections.Generic;

using Gcp = Pulumi.Gcp;

return await Deployment.RunAsync(() => 
{
    var member = new Gcp.BigQueryAnalyticsHub.DataExchangeIamMember("member", new()
    {
        Project = dataExchange.Project,
        Location = dataExchange.Location,
        DataExchangeId = dataExchange.DataExchangeId,
        Role = "roles/viewer",
        Member = "user:jane@example.com",

      dataExchangeId: ${dataExchange.dataExchangeId}
      role: roles/viewer
      member: user:jane@example.com

The member property specifies a single identity to grant the role. Unlike DataExchangeIamBinding, the DataExchangeIamMember resource is non-authoritative, preserving other members already assigned to the role. This approach works well for incremental access grants where you don’t want to manage the complete member list.

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 management solutions.

The examples reference pre-existing infrastructure such as BigQuery Analytics Hub data exchanges and IAM roles (predefined or custom). They focus on configuring access bindings rather than provisioning the underlying resources.

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

Conditional IAM bindings (condition property)
Policy-level management (DataExchangeIamPolicy resource)
Custom role creation and management
Audit logging and access monitoring

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

Frequently Asked Questions

Resource Selection & Conflicts

What's the difference between DataExchangeIamPolicy, DataExchangeIamBinding, and DataExchangeIamMember?

DataExchangeIamPolicy is authoritative and replaces the entire IAM policy. DataExchangeIamBinding is authoritative for a specific role, replacing all members for that role while preserving other roles. DataExchangeIamMember is non-authoritative and adds a single member to a role without affecting other members.

Can I use DataExchangeIamPolicy together with DataExchangeIamBinding or DataExchangeIamMember?

No, DataExchangeIamPolicy cannot be used with DataExchangeIamBinding or DataExchangeIamMember because they will conflict over policy control.

Can I use DataExchangeIamBinding and DataExchangeIamMember together?

Yes, but only if they don’t grant privileges to the same role. Using both resources on the same role will cause conflicts.

Which IAM resource should I use for my use case?

Use DataExchangeIamPolicy to manage the complete policy authoritatively. Use DataExchangeIamBinding to manage all members for a specific role. Use DataExchangeIamMember to add individual members without affecting existing ones.

IAM Configuration

How do I grant access to multiple users for the same role?

Use DataExchangeIamBinding with the members array containing multiple identities, such as ["user:jane@example.com", "user:john@example.com"].

What member identity formats are supported?

Supported formats include allUsers, allAuthenticatedUsers, user:{email}, serviceAccount:{email}, group:{email}, domain:{domain}, projectOwner:{projectid}, projectEditor:{projectid}, projectViewer:{projectid}, and federated identities like principal://iam.googleapis.com/....

How do I specify a custom IAM role?

Custom roles must use the format [projects|organizations]/{parent-name}/roles/{role-name}, such as projects/my-project/roles/customRole.
