Manage GCP Secret Manager Regional Secret IAM Policies

The gcp:secretmanager/regionalSecretIamPolicy:RegionalSecretIamPolicy resource, part of the Pulumi GCP provider, manages IAM access control for Secret Manager regional secrets. This guide focuses on four capabilities: authoritative policy replacement, role-based member management, individual member grants, and time-based access with IAM Conditions.

These resources reference existing regional secrets and require project and location configuration. The examples are intentionally small. Combine them with your own secret resources and member identities.

Grant a role to multiple members with RegionalSecretIamBinding

Teams managing secrets often need to grant the same role to multiple users or service accounts. RegionalSecretIamBinding manages all members for a specific role.

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

const binding = new gcp.secretmanager.RegionalSecretIamBinding("binding", {
    project: regional_secret_basic.project,
    location: regional_secret_basic.location,
    secretId: regional_secret_basic.secretId,
    role: "roles/secretmanager.secretAccessor",
    members: ["user:jane@example.com"],
});

import pulumi
import pulumi_gcp as gcp

binding = gcp.secretmanager.RegionalSecretIamBinding("binding",
    project=regional_secret_basic["project"],
    location=regional_secret_basic["location"],
    secret_id=regional_secret_basic["secretId"],
    role="roles/secretmanager.secretAccessor",
    members=["user:jane@example.com"])

package main

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

func main() {
	pulumi.Run(func(ctx *pulumi.Context) error {
		_, err := secretmanager.NewRegionalSecretIamBinding(ctx, "binding", &secretmanager.RegionalSecretIamBindingArgs{
			Project:  pulumi.Any(regional_secret_basic.Project),
			Location: pulumi.Any(regional_secret_basic.Location),
			SecretId: pulumi.Any(regional_secret_basic.SecretId),
			Role:     pulumi.String("roles/secretmanager.secretAccessor"),
			Members: pulumi.StringArray{
				pulumi.String("user:jane@example.com"),
			},
		})
		if err != nil {
			return err
		}
		return nil
	})
}

        Project = regional_secret_basic.Project,
        Location = regional_secret_basic.Location,
        SecretId = regional_secret_basic.SecretId,
        Role = "roles/secretmanager.secretAccessor",
        Members = new[]
        {

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

The members property lists all identities that receive the role. RegionalSecretIamBinding is authoritative for the specified role, replacing any existing members for that role while preserving other roles on the secret. The secretId, location, and project properties identify which regional secret to modify.

Add time-based access with IAM Conditions

Temporary access grants expire automatically when IAM Conditions evaluate to false, eliminating manual cleanup.

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

const binding = new gcp.secretmanager.RegionalSecretIamBinding("binding", {
    project: regional_secret_basic.project,

        expression: request.time < timestamp("2020-01-01T00:00:00Z")

The condition block adds a time-based constraint using Common Expression Language (CEL). The expression property defines when access is valid; here, access expires at midnight on 2020-01-01. The title property identifies the condition in audit logs. IAM Conditions have known limitations documented by Google Cloud.

Add a single member to a role with RegionalSecretIamMember

When multiple teams manage access to the same secret, RegionalSecretIamMember adds individual members without affecting others.

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

const member = new gcp.secretmanager.RegionalSecretIamMember("member", {
    project: regional_secret_basic.project,

    secretId: regional_secret_basic.secretId,
    role: "roles/secretmanager.secretAccessor",
    member: "user:jane@example.com",
});

import pulumi_gcp as gcp

member = gcp.secretmanager.RegionalSecretIamMember("member",
    project=regional_secret_basic["project"],
    location=regional_secret_basic["location"],
    secret_id=regional_secret_basic["secretId"],
    role="roles/secretmanager.secretAccessor",
    member="user:jane@example.com")

package main

import (

      role: roles/secretmanager.secretAccessor
      member: user:jane@example.com

The member property specifies a single identity (user, service account, or group). RegionalSecretIamMember is non-authoritative, preserving other members for the same role and all other roles on the secret. This resource can coexist with RegionalSecretIamBinding as long as they don’t manage the same role.

Replace the entire IAM policy with RegionalSecretIamPolicy

Some deployments require complete control over all IAM bindings, replacing any existing policy.

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

const admin = gcp.organizations.getIAMPolicy({
    bindings: [{
        role: "roles/secretmanager.secretAccessor",

The policyData property accepts output from the getIAMPolicy data source, which defines all role bindings in a single policy document. RegionalSecretIamPolicy is fully authoritative, replacing the entire IAM policy. It cannot be used alongside RegionalSecretIamBinding or RegionalSecretIamMember, as they will conflict over policy ownership.

Beyond these examples

These snippets focus on specific IAM management features: authoritative and non-authoritative IAM management, and time-based access with IAM Conditions. They’re intentionally minimal rather than full access control configurations.

The examples reference pre-existing infrastructure such as regional secrets (referenced as regional_secret_basic) and GCP project and location configuration. They focus on IAM policy configuration rather than creating the secrets themselves.

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

  • Service account and group member types (serviceAccount:, group:)
  • Complex IAM Condition expressions (resource attributes, request context)
  • Multiple role bindings in a single policy
  • IAM Condition limitations and known issues

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 RegionalSecretIamPolicy resource reference for all available configuration options.

Frequently Asked Questions

Resource Selection & Conflicts
Can I use RegionalSecretIamPolicy with RegionalSecretIamBinding or RegionalSecretIamMember?
No, RegionalSecretIamPolicy cannot be used with RegionalSecretIamBinding or RegionalSecretIamMember because they will conflict over the policy state. Choose one approach: use Policy alone for full control, or use Binding/Member for granular management.
Can I use RegionalSecretIamBinding and RegionalSecretIamMember together?
Yes, but only if they don’t grant privileges to the same role. Each role must be managed by either Binding or Member, not both.
Which IAM resource should I use for my secret?
Use RegionalSecretIamPolicy for authoritative control (replaces entire policy), RegionalSecretIamBinding for authoritative per-role management (preserves other roles), or RegionalSecretIamMember for non-authoritative member additions (preserves other members).
Configuration & Properties
What properties can't I change after creating the IAM policy?
The location, project, and secretId properties are immutable and cannot be changed after creation.
Where does the policyData come from?
The policyData must be generated using the gcp.organizations.getIAMPolicy data source, which defines the bindings and roles.
What happens if I don't specify a project or location?
If not specified, project and location are parsed from the parent resource identifier. If still unavailable, project defaults to the provider configuration.
IAM Conditions
What are the limitations of IAM Conditions?
IAM Conditions have known limitations documented by GCP. Review the limitations before implementing conditions in production.
How do I add time-based access conditions to my IAM policy?
Add a condition block with title, description, and expression properties. For example, use request.time < timestamp("2020-01-01T00:00:00Z") to expire access at a specific time.
Import & Migration
What formats can I use to import existing IAM policies?
You can import using four formats: full path (projects/{{project}}/locations/{{location}}/secrets/{{secret_id}}), project-scoped ({{project}}/{{location}}/{{secret_id}}), location-scoped ({{location}}/{{secret_id}}), or just the secret ID ({{secret_id}}).
How do I import a custom role?
Use the full name of the custom role in the format projects/my-project/roles/my-custom-role or organizations/my-org/roles/my-custom-role.
