Manage GCP Dataplex Entry Group IAM Policies

The gcp:dataplex/entryGroupIamPolicy:EntryGroupIamPolicy resource, part of the Pulumi GCP provider, manages IAM policies for Dataplex entry groups, controlling who can access and manage metadata catalog entries. This guide focuses on three approaches: authoritative policy replacement, role-level binding, and individual member grants.

These resources reference existing entry groups and require project/location configuration. The examples are intentionally small. Combine them with your own entry group infrastructure and organizational IAM patterns.

Replace the entire IAM policy for an entry group

When you need complete control over access permissions, set the entire IAM policy at once, replacing any existing configuration.

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

const admin = gcp.organizations.getIAMPolicy({
    bindings: [{
        role: "roles/viewer",
        members: ["user:jane@example.com"],
    }],
});
const policy = new gcp.dataplex.EntryGroupIamPolicy("policy", {
    project: testEntryGroupBasic.project,
    location: testEntryGroupBasic.location,
    entryGroupId: testEntryGroupBasic.entryGroupId,
    policyData: admin.then(admin => admin.policyData),
});

import pulumi
import pulumi_gcp as gcp

admin = gcp.organizations.get_iam_policy(bindings=[{
    "role": "roles/viewer",
    "members": ["user:jane@example.com"],
}])
policy = gcp.dataplex.EntryGroupIamPolicy("policy",
    project=test_entry_group_basic["project"],
    location=test_entry_group_basic["location"],
    entry_group_id=test_entry_group_basic["entryGroupId"],
    policy_data=admin.policy_data)

            members:
              - user:jane@example.com

The EntryGroupIamPolicy resource is authoritative: it replaces the entire IAM policy for the entry group. The policyData comes from the getIAMPolicy data source, which defines bindings (role-to-members mappings). This approach cannot be used alongside EntryGroupIamBinding or EntryGroupIamMember resources; they will conflict over policy ownership.

Grant a role to multiple members at once

When multiple users or service accounts need the same role, bind them all in a single resource while preserving other role assignments.

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

The EntryGroupIamBinding resource is authoritative for a specific role: it controls all members assigned to that role but leaves other roles untouched. The members array lists user accounts, service accounts, or groups. You can use multiple binding resources for different roles without conflict.

Add a single member to a role incrementally

When you need to grant access to one user without affecting other members of the same role, use the non-authoritative member resource.

      role: roles/viewer
      member: user:jane@example.com

The EntryGroupIamMember resource is non-authoritative: it adds one member to a role without replacing existing members. This is the most flexible approach for incremental access grants. You can combine multiple member resources for the same role, and they can coexist with binding resources as long as they target different roles.

Beyond these examples

These snippets focus on specific IAM management approaches: authoritative vs non-authoritative IAM management, and policy, binding, and member-level access control. They’re intentionally minimal rather than full access control systems.

The examples reference pre-existing infrastructure such as Dataplex entry groups, and GCP project and location configuration. They focus on IAM configuration rather than provisioning the underlying resources.

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

  • Conditional IAM bindings (condition blocks)
  • Custom role definitions
  • Service account creation and management
  • Entry group provisioning (focus is IAM only)

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 Dataplex EntryGroupIamPolicy resource reference for all available configuration options.

Frequently Asked Questions

Resource Selection & Conflicts
Why are my EntryGroup IAM resources conflicting with each other?
EntryGroupIamPolicy cannot be used with EntryGroupIamBinding or EntryGroupIamMember because Policy is authoritative and will overwrite changes made by the other resources. Use Policy alone, or use Binding/Member together without Policy.
Can I use EntryGroupIamBinding and EntryGroupIamMember together?
Yes, but only if they manage different roles. If both resources grant privileges to the same role, they’ll conflict. For example, you can use Binding for roles/viewer and Member for roles/editor without issues.
Which IAM resource should I use for my entry group?
Use EntryGroupIamPolicy to set the complete IAM policy authoritatively. Use EntryGroupIamBinding to manage all members for a specific role while preserving other roles. Use EntryGroupIamMember to add individual members without affecting existing members or other roles.
Configuration & Usage
How do I grant IAM access to users on an entry group?
For a single user, use EntryGroupIamMember with the role and member properties (e.g., member: "user:jane@example.com"). For multiple users, use EntryGroupIamBinding with the role and members array.
Where does the policyData for EntryGroupIamPolicy come from?
The policyData property requires output from the gcp.organizations.getIAMPolicy data source, which you configure with bindings specifying roles and members.
Import & Migration
How do I import IAM resources with custom roles?
Use the full name format for custom roles: [projects/my-project|organizations/my-org]/roles/my-custom-role in your import command.
