Manage GCP BigQuery Data Policy IAM Access

The gcp:bigquery/datapolicyv2DataPolicyIamMember:Datapolicyv2DataPolicyIamMember resource, part of the Pulumi GCP provider, manages IAM permissions for BigQuery data policies by granting roles to individual members, groups of members, or replacing the entire policy. This guide focuses on three capabilities: single-member role grants, multi-member role bindings, and authoritative policy replacement.

IAM resources for data policies come in three variants. The IamMember resource adds one member to a role non-authoritatively, preserving other members. The IamBinding resource manages all members for a specific role authoritatively. The IamPolicy resource replaces the entire policy authoritatively. All three reference existing BigQuery data policies and require valid member identifiers. The examples are intentionally small. Combine them with your own data policy resources and organizational identity structure.

Grant a role to a single member

Most IAM configurations start by granting a specific role to one user or service account, preserving existing role assignments while adding new members incrementally.

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

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

    role: "roles/viewer",
    member: "user:jane@example.com",
});

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

The member property specifies a single identity using one of several formats: user:email, serviceAccount:email, group:email, or special identifiers like allUsers. The role property defines the permission level. This resource is non-authoritative, meaning it adds the member without affecting other members already assigned to the role. The dataPolicyId, location, and project properties identify which data policy receives the permission grant.

Grant a role to multiple members at once

When multiple users or service accounts need the same permissions, binding them together simplifies management and ensures consistent access.

      role: roles/viewer
      members:
        - user:jane@example.com

The members property accepts a list of identities in the same formats as the single-member resource. This resource is authoritative for the specified role, meaning it replaces all members for that role. If other members were previously assigned to roles/viewer, they’re removed unless listed in the members array. Other roles in the policy remain unchanged.

Replace the entire IAM policy

Some workflows require complete control over all role assignments, replacing any existing policy with a new authoritative definition.

The policyData property accepts a complete IAM policy document, typically retrieved from the getIAMPolicy data source. The bindings array within the policy defines all role-to-members mappings. This resource is fully authoritative, replacing the entire IAM policy for the data policy. Any roles or members not included in the policy document are removed. This approach conflicts with IamMember and IamBinding resources; use one strategy per data policy.

Beyond these examples

These snippets focus on specific IAM management features: single-member grants, multi-member role bindings, and authoritative policy replacement. They’re intentionally minimal rather than full access control configurations.

The examples reference pre-existing infrastructure such as BigQuery data policies (referenced as basicDataPolicy). They focus on configuring IAM permissions rather than provisioning the data policies themselves.

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

  • Conditional IAM bindings (condition property)
  • Custom role definitions
  • Federated identity configuration
  • Policy retrieval via data sources

These omissions are intentional: the goal is to illustrate how each IAM resource type is wired, not provide drop-in access control modules. See the Datapolicyv2DataPolicyIamMember 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 given role, managing all members for that role while preserving other roles. Datapolicyv2DataPolicyIamMember is non-authoritative, adding a single member to a role without affecting other members.
Can I use these IAM resources together?
Datapolicyv2DataPolicyIamPolicy cannot be used with Datapolicyv2DataPolicyIamBinding or Datapolicyv2DataPolicyIamMember, as they will conflict over policy control. However, Datapolicyv2DataPolicyIamBinding and Datapolicyv2DataPolicyIamMember can be used together if they don’t grant privileges to the same role.
Which IAM resource should I use for my use case?
Use IamPolicy when you need full control over the entire policy. Use IamBinding when managing all members for specific roles. Use IamMember when adding individual members without affecting existing permissions.
IAM Configuration
What member identity formats are supported?
Supported formats include allUsers, allAuthenticatedUsers, user:{email}, serviceAccount:{email}, group:{email}, domain:{domain}, projectOwner/Editor/Viewer:{projectid}, and federated identities like principal://iam.googleapis.com/....
What format do custom roles require?
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 & Migration
How do I import an existing IAM member binding?
Use space-delimited identifiers: pulumi import gcp:bigquery/datapolicyv2DataPolicyIamMember:Datapolicyv2DataPolicyIamMember editor "projects/{{project}}/locations/{{location}}/dataPolicies/{{data_policy_id}} roles/viewer user:jane@example.com". The resource identifier, role, and member identity are required.
