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 regional secrets in Secret Manager. The provider offers three related resources: RegionalSecretIamPolicy (replaces entire policy), RegionalSecretIamBinding (manages all members for one role), and RegionalSecretIamMember (adds individual members). This guide focuses on three capabilities: role-based access with Binding resources, individual member grants with Member resources, and time-based access with IAM Conditions.

These resources reference existing regional secrets and require the secret’s project, location, and ID. The examples are intentionally small. Combine them with your own secret resources and organizational access patterns.

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, replacing any existing members for that role while preserving other roles on the secret.

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"])

func main() {
	pulumi.Run(func(ctx *pulumi.Context) error {
		_, err := secretmanager.NewRegionalSecretIamBinding(ctx, "binding", &secretmanager.RegionalSecretIamBindingArgs{
			Project:  pulumi.Any(regional_secret_basic.Project),

		})
		if err != nil {

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

The role property specifies which permission set to grant (here, secretAccessor allows reading secret values). The members array lists all identities that should have this role. RegionalSecretIamBinding is authoritative for its role: it replaces any existing members for secretAccessor but leaves other roles untouched.

Add time-based access with IAM Conditions

Temporary access grants expire automatically when IAM Conditions evaluate to false, eliminating manual cleanup for time-limited permissions.

        description: Expiring at midnight of 2019-12-31
        expression: request.time < timestamp("2020-01-01T00:00:00Z")

The condition block adds a time constraint to the role binding. The expression property uses Common Expression Language (CEL) to compare request.time against a timestamp. When the condition evaluates to false (after 2019-12-31), GCP denies access automatically. The title property identifies the condition in audit logs and the console.

Add a single member to a role with RegionalSecretIamMember

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

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

const member = new gcp.secretmanager.RegionalSecretIamMember("member", {
    project: regional_secret_basic.project,
    location: regional_secret_basic.location,
    secretId: regional_secret_basic.secretId,
    role: "roles/secretmanager.secretAccessor",
    member: "user:jane@example.com",
});

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

func main() {

			SecretId: pulumi.Any(regional_secret_basic.SecretId),

	})

    var member = new Gcp.SecretManager.RegionalSecretIamMember("member", new()
    {
        Project = regional_secret_basic.Project,
        Location = regional_secret_basic.Location,
        SecretId = regional_secret_basic.SecretId,
        Role = "roles/secretmanager.secretAccessor",

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

The member property specifies a single identity (user, service account, or group). Unlike RegionalSecretIamBinding, this resource is non-authoritative: it adds one member to the role without removing existing members. Multiple RegionalSecretIamMember resources can safely grant the same role to different members.

Beyond these examples

These snippets focus on specific IAM management features: role-based access control (Binding and Member resources) and time-based access with IAM Conditions. They’re intentionally minimal rather than complete access control configurations.

The examples reference pre-existing infrastructure such as regional secrets (referenced but not created) and GCP project and location configuration. They focus on configuring IAM permissions rather than provisioning secrets or service accounts.

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

Full policy replacement with RegionalSecretIamPolicy
Complex condition expressions (multiple clauses, resource attributes)
Service account creation and management
Secret creation and version management

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 Regional Secret IAM Policy 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. Choose one approach: use Policy alone, or use Binding and Member together.

Can I use RegionalSecretIamBinding and RegionalSecretIamMember together?

Yes, but only if they don’t grant privileges to the same role. If both resources manage the same role, they will conflict.

What's the difference between RegionalSecretIamPolicy, RegionalSecretIamBinding, and RegionalSecretIamMember?

RegionalSecretIamPolicy is authoritative and replaces the entire IAM policy. RegionalSecretIamBinding is authoritative for a specific role but preserves other roles. RegionalSecretIamMember is non-authoritative and preserves other members for the same role.

Configuration & Setup

What properties are immutable after creation?

The location, project, and secretId properties cannot be changed after the resource is created.

How do I add time-based or conditional access to a secret?

Use the condition property with title, description, and expression fields. For example, set expression to request.time < timestamp("2020-01-01T00:00:00Z") to expire access at a specific time.

Where does the policyData come from?

The policyData must be generated by the gcp.organizations.getIAMPolicy data source, which defines the bindings, roles, and members.

Known Limitations

Are there any limitations with IAM Conditions?

Yes, IAM Conditions have known limitations. If you’re experiencing issues with conditions, review the GCP documentation on IAM Conditions limitations.
