Configure GCP BeyondCorp Security Gateway IAM Bindings

The gcp:beyondcorp/securityGatewayIamBinding:SecurityGatewayIamBinding resource, part of the Pulumi GCP provider, manages IAM role bindings for BeyondCorp Security Gateway resources. This guide focuses on three capabilities: granting roles to multiple members, adding individual members to roles, and time-based access with IAM Conditions.

Bindings reference existing Security Gateway resources and require the BeyondCorp API enabled in your project. The examples are intentionally small. Combine them with your own Security Gateway infrastructure and identity management.

Grant a role to multiple members with binding

Teams managing gateway access often need to grant the same role to multiple users or service accounts at once.

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

const binding = new gcp.beyondcorp.SecurityGatewayIamBinding("binding", {
    project: example.project,
    location: example.location,
    securityGatewayId: example.securityGatewayId,
    role: "roles/beyondcorp.securityGatewayUser",
    members: ["user:jane@example.com"],
});

import pulumi
import pulumi_gcp as gcp

binding = gcp.beyondcorp.SecurityGatewayIamBinding("binding",
    project=example["project"],
    location=example["location"],
    security_gateway_id=example["securityGatewayId"],
    role="roles/beyondcorp.securityGatewayUser",
    members=["user:jane@example.com"])

package main

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

func main() {
	pulumi.Run(func(ctx *pulumi.Context) error {
		_, err := beyondcorp.NewSecurityGatewayIamBinding(ctx, "binding", &beyondcorp.SecurityGatewayIamBindingArgs{
			Project:           pulumi.Any(example.Project),
			Location:          pulumi.Any(example.Location),
			SecurityGatewayId: pulumi.Any(example.SecurityGatewayId),
			Role:              pulumi.String("roles/beyondcorp.securityGatewayUser"),
			Members: pulumi.StringArray{
				pulumi.String("user:jane@example.com"),
			},
		})
		if err != nil {
			return err
		}
		return nil
	})
}

return await Deployment.RunAsync(() => 
{
    var binding = new Gcp.Beyondcorp.SecurityGatewayIamBinding("binding", new()
    {
        Project = example.Project,
        Location = example.Location,
        SecurityGatewayId = example.SecurityGatewayId,
        Role = "roles/beyondcorp.securityGatewayUser",
        Members = new[]
        {
            "user:jane@example.com",
        },
    });

      securityGatewayId: ${example.securityGatewayId}
      role: roles/beyondcorp.securityGatewayUser
      members:
        - user:jane@example.com

The binding resource is authoritative for the specified role: it replaces the complete member list. The members array accepts user emails, service accounts, groups, and special identifiers like allAuthenticatedUsers. The securityGatewayId, location, and project properties identify which gateway to configure.

Add time-based access with IAM Conditions

Organizations with temporary contractors can use IAM Conditions to automatically expire permissions.

    project: example.project,

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

The condition block adds temporal or attribute-based constraints to the role binding. The expression uses Common Expression Language (CEL) to define when access is granted. Here, the condition checks request.time against a timestamp, automatically revoking access after December 31, 2019. The title and description provide human-readable context for auditing.

Add a single member to an existing role

When onboarding individual users, member resources add one identity without affecting others.

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

const member = new gcp.beyondcorp.SecurityGatewayIamMember("member", {
    project: example.project,
    location: example.location,
    securityGatewayId: example.securityGatewayId,
    role: "roles/beyondcorp.securityGatewayUser",
    member: "user:jane@example.com",
});

import pulumi
import pulumi_gcp as gcp

member = gcp.beyondcorp.SecurityGatewayIamMember("member",
    project=example["project"],
    location=example["location"],
    security_gateway_id=example["securityGatewayId"],
    role="roles/beyondcorp.securityGatewayUser",
    member="user:jane@example.com")

package main

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

func main() {
	pulumi.Run(func(ctx *pulumi.Context) error {
		_, err := beyondcorp.NewSecurityGatewayIamMember(ctx, "member", &beyondcorp.SecurityGatewayIamMemberArgs{
			Project:           pulumi.Any(example.Project),
			Location:          pulumi.Any(example.Location),
			SecurityGatewayId: pulumi.Any(example.SecurityGatewayId),
			Role:              pulumi.String("roles/beyondcorp.securityGatewayUser"),
			Member:            pulumi.String("user:jane@example.com"),
		})
		if err != nil {
			return err
		}
		return nil
	})
}

using System.Collections.Generic;

        SecurityGatewayId = example.SecurityGatewayId,
        Role = "roles/beyondcorp.securityGatewayUser",
        Member = "user:jane@example.com",

      role: roles/beyondcorp.securityGatewayUser
      member: user:jane@example.com

The member resource is non-authoritative: it adds one identity to a role while preserving other members. Use member when you need to grant access incrementally. Use binding when you want to define the complete member list for a role. The member property accepts the same identity formats as the members array in bindings.

Beyond these examples

These snippets focus on specific IAM binding features: role binding for multiple members, single-member grants, and time-based IAM Conditions. They’re intentionally minimal rather than full access control configurations.

The examples reference pre-existing infrastructure such as BeyondCorp Security Gateway resources and a GCP project with the BeyondCorp API enabled. They focus on configuring IAM bindings rather than provisioning the gateways themselves.

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

Full policy replacement (SecurityGatewayIamPolicy)
Complex condition expressions (attribute-based access)
Custom role definitions
Audit logging configuration

These omissions are intentional: the goal is to illustrate how each IAM binding feature is wired, not provide drop-in access control modules. See the SecurityGatewayIamBinding resource reference for all available configuration options.

Frequently Asked Questions

Resource Selection & Conflicts

What's the difference between SecurityGatewayIamPolicy, SecurityGatewayIamBinding, and SecurityGatewayIamMember?

SecurityGatewayIamPolicy is fully authoritative and replaces the entire IAM policy. SecurityGatewayIamBinding is authoritative for a specific role, preserving other roles. SecurityGatewayIamMember is non-authoritative, adding members without affecting other members for the same role.

Can I use multiple IAM resource types together?

SecurityGatewayIamPolicy cannot be used with SecurityGatewayIamBinding or SecurityGatewayIamMember as they will conflict. However, SecurityGatewayIamBinding and SecurityGatewayIamMember can be used together only if they grant different roles.

IAM Configuration & Member Formats

What member identity formats are supported?

You can use allUsers, allAuthenticatedUsers, user:{email}, serviceAccount:{email}, group:{email}, domain:{domain}, projectOwner:projectid, projectEditor:projectid, projectViewer:projectid, or federated identities like principal://iam.googleapis.com/locations/global/workforcePools/example-contractors/subject/joe@example.com.

What format should I use for custom roles?

Custom roles must use the format [projects|organizations]/{parent-name}/roles/{role-name}.

What value should I use for the location property?

The location property must be omitted or set to global. If not specified, it’s parsed from the parent resource identifier or taken from the provider configuration.

Conditions & Advanced Features

How do I add time-based access expiration?

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

Are there limitations when using IAM Conditions?

Yes, IAM Conditions have known limitations. Review the GCP IAM Conditions documentation if you encounter issues.

Import & Resource Identification

How do I import an existing IAM binding?

Use space-delimited identifiers: the resource path and role. For example:

pulumi import gcp:beyondcorp/securityGatewayIamBinding:SecurityGatewayIamBinding editor "projects/{{project}}/locations/{{location}}/securityGateways/{{security_gateway_id}} roles/beyondcorp.securityGatewayUser"
