Configure GCP Logging View IAM Permissions

The gcp:logging/logViewIamBinding:LogViewIamBinding resource, part of the Pulumi GCP provider, manages IAM role bindings for Cloud Logging log views, controlling which identities can access specific views. This guide focuses on three capabilities: authoritative role binding with member lists, non-authoritative individual member grants, and time-based IAM Conditions.

IAM bindings for log views reference existing log views by their parent, location, bucket, and name. The examples are intentionally small. Combine them with your own log view infrastructure and identity management.

Grant a role to multiple members with LogViewIamBinding

When you need to grant the same role to multiple users or service accounts, LogViewIamBinding manages all members for that role as a single unit.

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

const binding = new gcp.logging.LogViewIamBinding("binding", {
    parent: loggingLogView.parent,
    location: loggingLogView.location,
    bucket: loggingLogView.bucket,
    name: loggingLogView.name,
    role: "roles/logging.admin",
    members: ["user:jane@example.com"],
});

import pulumi
import pulumi_gcp as gcp

binding = gcp.logging.LogViewIamBinding("binding",
    parent=logging_log_view["parent"],
    location=logging_log_view["location"],
    bucket=logging_log_view["bucket"],
    name=logging_log_view["name"],
    role="roles/logging.admin",
    members=["user:jane@example.com"])

package main

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

func main() {
	pulumi.Run(func(ctx *pulumi.Context) error {
		_, err := logging.NewLogViewIamBinding(ctx, "binding", &logging.LogViewIamBindingArgs{
			Parent:   pulumi.Any(loggingLogView.Parent),
			Location: pulumi.Any(loggingLogView.Location),
			Bucket:   pulumi.Any(loggingLogView.Bucket),
			Name:     pulumi.Any(loggingLogView.Name),
			Role:     pulumi.String("roles/logging.admin"),
			Members: pulumi.StringArray{
				pulumi.String("user:jane@example.com"),
			},
		})
		if err != nil {
			return err
		}
		return nil
	})
}

using Gcp = Pulumi.Gcp;

return await Deployment.RunAsync(() => 
{
    var binding = new Gcp.Logging.LogViewIamBinding("binding", new()
    {
        Parent = loggingLogView.Parent,
        Location = loggingLogView.Location,
        Bucket = loggingLogView.Bucket,
        Name = loggingLogView.Name,
        Role = "roles/logging.admin",
        Members = new[]
        {
            "user:jane@example.com",
        },
    });

});

  binding:
    type: gcp:logging:LogViewIamBinding
    properties:
      parent: ${loggingLogView.parent}
      location: ${loggingLogView.location}

      name: ${loggingLogView.name}
      role: roles/logging.admin
      members:
        - user:jane@example.com

The binding is authoritative for the specified role: it replaces any existing members for that role on the log view. The members array accepts user accounts, service accounts, groups, and special identifiers like allAuthenticatedUsers. The parent, location, bucket, and name properties identify the log view to bind permissions to.

Add time-based conditions to role bindings

Access grants sometimes need expiration dates or time-based restrictions. IAM Conditions attach temporal constraints to role bindings.

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

const binding = new gcp.logging.LogViewIamBinding("binding", {
    parent: loggingLogView.parent,
    location: loggingLogView.location,

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

The condition block adds a CEL expression that must evaluate to true for the binding to take effect. Here, the expression checks that the request time is before midnight on January 1, 2020. The title and description provide human-readable context for the condition. Note that IAM Conditions have known limitations documented by Google Cloud.

Add individual members with LogViewIamMember

When you need to grant access to one user without affecting other members of the same role, LogViewIamMember provides non-authoritative access control.

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

const member = new gcp.logging.LogViewIamMember("member", {
    parent: loggingLogView.parent,
    location: loggingLogView.location,
    bucket: loggingLogView.bucket,
    name: loggingLogView.name,
    role: "roles/logging.admin",
    member: "user:jane@example.com",
});

import pulumi
import pulumi_gcp as gcp

member = gcp.logging.LogViewIamMember("member",
    parent=logging_log_view["parent"],
    location=logging_log_view["location"],
    bucket=logging_log_view["bucket"],
    name=logging_log_view["name"],
    role="roles/logging.admin",
    member="user:jane@example.com")

package main

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

func main() {
	pulumi.Run(func(ctx *pulumi.Context) error {
		_, err := logging.NewLogViewIamMember(ctx, "member", &logging.LogViewIamMemberArgs{
			Parent:   pulumi.Any(loggingLogView.Parent),
			Location: pulumi.Any(loggingLogView.Location),
			Bucket:   pulumi.Any(loggingLogView.Bucket),
			Name:     pulumi.Any(loggingLogView.Name),
			Role:     pulumi.String("roles/logging.admin"),
			Member:   pulumi.String("user:jane@example.com"),
		})
		if err != nil {
			return err
		}
		return nil
	})
}

return await Deployment.RunAsync(() =>

        Bucket = loggingLogView.Bucket,

Unlike LogViewIamBinding, this resource adds a single member to a role without replacing existing members. Multiple LogViewIamMember resources can target the same role, and they can coexist with LogViewIamBinding resources as long as they don’t grant the same 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 with member lists, individual 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 log views (parent, location, bucket, name references). They focus on configuring IAM bindings rather than provisioning the log views themselves.

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

  • LogViewIamPolicy for full policy replacement
  • Attribute-based conditions beyond time expressions
  • Custom role definitions
  • Service account creation and management

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 LogViewIamBinding resource reference for all available configuration options.

Frequently Asked Questions

Resource Selection & Conflicts
What's the difference between LogViewIamPolicy, LogViewIamBinding, and LogViewIamMember?
gcp.logging.LogViewIamPolicy is authoritative and replaces the entire IAM policy. gcp.logging.LogViewIamBinding is authoritative for a specific role, preserving other roles. gcp.logging.LogViewIamMember is non-authoritative, adding individual members without affecting existing ones.
Can I use LogViewIamPolicy together with LogViewIamBinding or LogViewIamMember?
No, gcp.logging.LogViewIamPolicy cannot be used with gcp.logging.LogViewIamBinding or gcp.logging.LogViewIamMember because they will conflict over the policy state.
Can I use LogViewIamBinding and LogViewIamMember together?
Yes, but only if they manage different roles. Using both resources for the same role will cause conflicts.
IAM Configuration
What member identity formats are supported?
Supported formats include allUsers, allAuthenticatedUsers, user:{email}, serviceAccount:{email}, group:{email}, domain:{domain}, projectOwner/Editor/Viewer:{projectid}, and federated identities like principal://iam.googleapis.com/....
How do I add time-based or conditional access restrictions?
Use the condition property with title, description, and expression. For example, set expression: "request.time < timestamp(\"2020-01-01T00:00:00Z\")" to expire access at a specific time.
What are the limitations of IAM Conditions?
IAM Conditions are supported but have known limitations. Review the Google Cloud documentation at https://cloud.google.com/iam/docs/conditions-overview#limitations if you encounter issues.
Advanced Configuration
How do I specify a custom IAM role?
Custom roles must use the full path format: projects/{project-id}/roles/{role-name} or organizations/{org-id}/roles/{role-name}.
What properties can't be changed after creation?
The bucket, location, name, parent, role, and condition properties are immutable and cannot be modified after the resource is created.
Can I use only one LogViewIamBinding per role?
Yes, only one gcp.logging.LogViewIamBinding resource can be used per role. To add multiple members to the same role, include them all in the members array of a single binding.
