Manage GCP Dataplex Entry Type IAM Policies

The gcp:dataplex/entryTypeIamPolicy:EntryTypeIamPolicy resource, part of the Pulumi GCP provider, manages IAM access control for Dataplex entry types at three levels: complete policy replacement, role-level binding, or individual member assignment. This guide focuses on three capabilities: authoritative policy replacement (EntryTypeIamPolicy), role-level member binding (EntryTypeIamBinding), and individual member assignment (EntryTypeIamMember).

These resources reference existing Dataplex entry types and require project/location configuration. The examples are intentionally small. Combine them with your own entry type definitions and organizational access patterns.

Replace the entire IAM policy for an entry type

When you need complete control over who can access a Dataplex entry type, you can set the entire IAM policy at once, replacing any existing permissions.

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.EntryTypeIamPolicy("policy", {
    project: testEntryTypeBasic.project,
    location: testEntryTypeBasic.location,
    entryTypeId: testEntryTypeBasic.entryTypeId,
    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.EntryTypeIamPolicy("policy",
    project=test_entry_type_basic["project"],
    location=test_entry_type_basic["location"],
    entry_type_id=test_entry_type_basic["entryTypeId"],
    policy_data=admin.policy_data)

func main() {
	pulumi.Run(func(ctx *pulumi.Context) error {
		admin, err := organizations.LookupIAMPolicy(ctx, &organizations.LookupIAMPolicyArgs{
			Bindings: []organizations.GetIAMPolicyBinding{

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

			Project:     pulumi.Any(testEntryTypeBasic.Project),
			Location:    pulumi.Any(testEntryTypeBasic.Location),
			EntryTypeId: pulumi.Any(testEntryTypeBasic.EntryTypeId),
			PolicyData:  pulumi.String(admin.PolicyData),
		})
		if err != nil {

		return nil
	})

            members:
              - user:jane@example.com

The EntryTypeIamPolicy resource is authoritative: it replaces all existing IAM bindings on the entry type. The policyData comes from the getIAMPolicy data source, which defines bindings as role-member pairs. This approach gives you full control but requires careful coordination, since it overwrites any permissions not included in the policy.

Grant a role to multiple members at once

Teams often need to grant the same role to several users or service accounts without affecting other role assignments.

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

The EntryTypeIamBinding resource is authoritative for a specific role: it replaces all members for that role while preserving other roles on the entry type. The members property accepts a list of identities (users, service accounts, groups). This is useful when you want to manage who has a particular role without touching other permissions.

Add a single member to a role incrementally

When you want to grant access to one user without disturbing existing permissions, you can add individual members to roles.

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

const member = new gcp.dataplex.EntryTypeIamMember("member", {
    project: testEntryTypeBasic.project,

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

The EntryTypeIamMember resource is non-authoritative: it adds one member to a role without affecting other members of that role or other roles on the entry type. The member property takes a single identity. This is the safest option when multiple teams manage access to the same entry type, since it won’t overwrite others’ changes.

Beyond these examples

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

The examples reference pre-existing infrastructure such as Dataplex entry types (referenced by entryTypeId), and GCP project and location configuration. They focus on IAM binding configuration rather than provisioning the underlying entry types.

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

Conditional IAM bindings (condition blocks)
Service account impersonation
Custom role definitions
Audit logging configuration

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 EntryType IAM Policy resource reference for all available configuration options.

Frequently Asked Questions

Resource Selection & Conflicts

What's the difference between EntryTypeIamPolicy, EntryTypeIamBinding, and EntryTypeIamMember?

You have three options for managing IAM permissions:

EntryTypeIamPolicy - Authoritative. Replaces the entire IAM policy.
EntryTypeIamBinding - Authoritative for a specific role. Preserves other roles in the policy.
EntryTypeIamMember - Non-authoritative. Adds a single member to a role without affecting other members.

Can I use EntryTypeIamPolicy with EntryTypeIamBinding or EntryTypeIamMember?

No, EntryTypeIamPolicy cannot be used alongside EntryTypeIamBinding or EntryTypeIamMember because they will conflict over the policy configuration.

Can I use EntryTypeIamBinding and EntryTypeIamMember together?

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

Configuration & Usage

How do I configure EntryTypeIamPolicy?

Use the gcp.organizations.getIAMPolicy data source to generate policy data with your desired bindings, then pass the policyData output to the EntryTypeIamPolicy resource along with entryTypeId, location, and project.

How do I grant a role to multiple members at once?

Use EntryTypeIamBinding with the members property set to an array of identities (e.g., ["user:jane@example.com", "group:admins@example.com"]).

How do I add a single member to a role without affecting others?

Use EntryTypeIamMember with the member property set to a single identity (e.g., "user:jane@example.com"). This preserves existing members for that role.

What format do I need for custom roles?

Custom roles must use the full name format: projects/my-project/roles/my-custom-role or organizations/my-org/roles/my-custom-role.

Import

What import formats are supported for EntryType IAM resources?

Four formats are supported (from most to least specific):

projects/{{project}}/locations/{{location}}/entryTypes/{{entry_type_id}}
{{project}}/{{location}}/{{entry_type_id}}
{{location}}/{{entry_type_id}}
{{entry_type_id}}

Missing values are automatically taken from the provider configuration.
