Manage GCP Colab Runtime Template IAM Policies

The gcp:colab/runtimeTemplateIamPolicy:RuntimeTemplateIamPolicy resource, part of the Pulumi GCP provider, manages IAM access control for Colab Enterprise runtime templates. This resource is one of three approaches for managing permissions: it replaces the entire IAM policy authoritatively. This guide focuses on three capabilities: authoritative policy replacement, role-level member binding, and incremental member addition.

These resources reference existing runtime templates by project, location, and name. The RuntimeTemplateIamPolicy resource cannot be used with RuntimeTemplateIamBinding or RuntimeTemplateIamMember, as they will conflict over policy state. RuntimeTemplateIamBinding and RuntimeTemplateIamMember can coexist if they manage different roles. The examples are intentionally small. Combine them with your own runtime template infrastructure and organizational IAM strategy.

Replace the entire IAM policy authoritatively

When you need complete control over who can access a runtime template, you can set the entire IAM policy at once.

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.colab.RuntimeTemplateIamPolicy("policy", {
    project: runtime_template.project,
    location: runtime_template.location,
    runtimeTemplate: runtime_template.name,
    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.colab.RuntimeTemplateIamPolicy("policy",
    project=runtime_template["project"],
    location=runtime_template["location"],
    runtime_template=runtime_template["name"],
    policy_data=admin.policy_data)

package main

	"github.com/pulumi/pulumi/sdk/v3/go/pulumi"
)

func main() {
	pulumi.Run(func(ctx *pulumi.Context) error {
		admin, err := organizations.LookupIAMPolicy(ctx, &organizations.LookupIAMPolicyArgs{
			Bindings: []organizations.GetIAMPolicyBinding{
				{
					Role: "roles/viewer",
					Members: []string{
						"user:jane@example.com",
					},
				},
			},
		}, nil)
		if err != nil {
			return err
		}
		_, err = colab.NewRuntimeTemplateIamPolicy(ctx, "policy", &colab.RuntimeTemplateIamPolicyArgs{
			Project:         pulumi.Any(runtime_template.Project),
			Location:        pulumi.Any(runtime_template.Location),
			RuntimeTemplate: pulumi.Any(runtime_template.Name),
			PolicyData:      pulumi.String(admin.PolicyData),
		})
		if err != nil {
			return err
		}
		return nil
	})
}

            members:

The RuntimeTemplateIamPolicy resource replaces any existing policy on the runtime template. The policyData comes from the getIAMPolicy data source, which defines bindings (role-to-members mappings). This approach is authoritative: any permissions not in policyData are removed.

Grant a role to multiple members at once

When multiple users or service accounts need the same level of access, you can bind them all to a single role.

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

const binding = new gcp.colab.RuntimeTemplateIamBinding("binding", {
    project: runtime_template.project,
    location: runtime_template.location,
    runtimeTemplate: runtime_template.name,
    role: "roles/viewer",
    members: ["user:jane@example.com"],
});

    location=runtime_template["location"],
    runtime_template=runtime_template["name"],
    role="roles/viewer",
    members=["user:jane@example.com"])

package main

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

func main() {
	pulumi.Run(func(ctx *pulumi.Context) error {
		_, err := colab.NewRuntimeTemplateIamBinding(ctx, "binding", &colab.RuntimeTemplateIamBindingArgs{
			Project:         pulumi.Any(runtime_template.Project),
			Location:        pulumi.Any(runtime_template.Location),
			RuntimeTemplate: pulumi.Any(runtime_template.Name),
			Role:            pulumi.String("roles/viewer"),
			Members: pulumi.StringArray{
				pulumi.String("user:jane@example.com"),
			},
		})
		if err != nil {
			return err
		}
		return nil
	})
}

        Project = runtime_template.Project,

        RuntimeTemplate = runtime_template.Name,
        Role = "roles/viewer",
        Members = new[]
        {

      runtimeTemplate: ${["runtime-template"].name}
      role: roles/viewer
      members:
        - user:jane@example.com

The RuntimeTemplateIamBinding resource is authoritative for the specified role but preserves other roles on the template. The members array lists all identities that should have this role. If you later remove a member from the array, they lose access.

Add a single member to a role incrementally

When you need to grant access to one additional user without affecting existing permissions, you can add individual members.

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

const member = new gcp.colab.RuntimeTemplateIamMember("member", {
    project: runtime_template.project,
    location: runtime_template.location,
    runtimeTemplate: runtime_template.name,
    role: "roles/viewer",
    member: "user:jane@example.com",
});

import pulumi
import pulumi_gcp as gcp

member = gcp.colab.RuntimeTemplateIamMember("member",
    project=runtime_template["project"],
    location=runtime_template["location"],
    runtime_template=runtime_template["name"],
    role="roles/viewer",
    member="user:jane@example.com")

package main

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

func main() {
	pulumi.Run(func(ctx *pulumi.Context) error {
		_, err := colab.NewRuntimeTemplateIamMember(ctx, "member", &colab.RuntimeTemplateIamMemberArgs{
			Project:         pulumi.Any(runtime_template.Project),
			Location:        pulumi.Any(runtime_template.Location),
			RuntimeTemplate: pulumi.Any(runtime_template.Name),
			Role:            pulumi.String("roles/viewer"),
			Member:          pulumi.String("user:jane@example.com"),
		})
		if err != nil {
			return err
		}
		return nil
	})
}

using System.Collections.Generic;

using Gcp = Pulumi.Gcp;

return await Deployment.RunAsync(() => 
{
    var member = new Gcp.Colab.RuntimeTemplateIamMember("member", new()

        Project = runtime_template.Project,
        Location = runtime_template.Location,
        RuntimeTemplate = runtime_template.Name,
        Role = "roles/viewer",
        Member = "user:jane@example.com",
    });

});

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

The RuntimeTemplateIamMember resource is non-authoritative: it adds one member to one role without affecting other members of that role or other roles entirely. This is useful when multiple teams manage access independently, as each can add their own members without coordinating.

Beyond these examples

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

The examples reference pre-existing infrastructure such as Colab Enterprise runtime templates (by project, location, and name). They focus on configuring IAM permissions rather than provisioning the templates themselves.

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

Conditional IAM bindings (conditions)
Custom role definitions
Service account impersonation
Organization and folder-level policies

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 RuntimeTemplateIamPolicy resource reference for all available configuration options.

Frequently Asked Questions

Resource Selection & Conflicts

Which IAM resource should I use to manage RuntimeTemplate permissions?

Choose based on your needs: gcp.colab.RuntimeTemplateIamPolicy for full policy control (replaces entire policy), gcp.colab.RuntimeTemplateIamBinding for managing all members of a specific role (authoritative per role), or gcp.colab.RuntimeTemplateIamMember for adding individual members without affecting others (non-authoritative).

Can I use RuntimeTemplateIamPolicy with RuntimeTemplateIamBinding or RuntimeTemplateIamMember?

No, gcp.colab.RuntimeTemplateIamPolicy cannot be used with gcp.colab.RuntimeTemplateIamBinding or gcp.colab.RuntimeTemplateIamMember because they will conflict over policy control.

Can I use RuntimeTemplateIamBinding and RuntimeTemplateIamMember together?

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

Configuration & Properties

What properties can't I change after creating a RuntimeTemplateIamPolicy?

The location, project, and runtimeTemplate properties are immutable and cannot be changed after creation.

Where does the policyData come from?

The policyData is generated by the gcp.organizations.getIAMPolicy data source, as shown in the IamPolicy example.

Usage Patterns

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

Use gcp.colab.RuntimeTemplateIamBinding with a members array containing all the members you want to grant the role to (e.g., ["user:jane@example.com", "user:john@example.com"]).
