GCP Load Balancer Universal Orchestrator Extension

Support · Installation · License · Related Integrations

Overview

The Google Cloud Platform (GCP) Load Balancer Orchestrator allows for the management of Google Cloud Platform Load Balancer certificate stores. Inventory, Management-Add, and Management-Remove functions are supported. Also, re-binding to endpoints IS supported for certificate renewals (but NOT adding new certificates). The orchestrator uses the Google Cloud Compute Engine API (https://cloud.google.com/compute/docs/reference/rest/v1) to manage stores.

Compatibility

This integration is compatible with Keyfactor Universal Orchestrator version 10.1 and later.

The GCP Load Balancer Universal Orchestrator extension is supported by Keyfactor. If you require support for any issues or have feature request, please open a support ticket by either contacting your Keyfactor representative or via the Keyfactor Support Portal at https://support.keyfactor.com.

If you want to contribute bug fixes or additional enhancements, use the Pull requests tab.

Requirements & Prerequisites

Before installing the GCP Load Balancer Universal Orchestrator extension, we recommend that you install kfutil. Kfutil is a command-line tool that simplifies the process of creating store types, installing extensions, and instantiating certificate stores in Keyfactor Command.

The orchestrator extension supports having credentials provided by the environment, environment variable, or passed manually from Keyfactor Command. You can read more about the first two options here.

To pass credentials from Keyfactor Command you need to first create a service account within GCP and then download a service account key Remember to assign the appropriate role/permissions for the service account (see below). Afterwards inside Keyfactor Command copy and paste the contents of the service account key in the password field for the GCP Certificate Store you create.

The following are the required permissions for the GCP service account:

• compute.sslCertificates.create
• compute.sslCertificates.delete
• compute.sslCertificates.list
• compute.sslCertificates.get
• compute.targetHttpsProxies.list
• compute.targetHttpsProxies.setSslCertificates
• compute.regionSslCertificates.list

GCPLoadBal Certificate Store Type

To use the GCP Load Balancer Universal Orchestrator extension, you must create the GCPLoadBal Certificate Store Type. This only needs to happen once per Keyfactor Command instance.

This will reach out to GitHub and pull the latest store-type definition

# GCP Load Balancer
kfutil store-types create GCPLoadBal

Offline creation using integration-manifest file:

If required, it is possible to create store types from the integration-manifest.json included in this repo. You would first download the integration-manifest.json and then run the following command in your offline environment.

kfutil store-types create --from-file integration-manifest.json

Manual Creation

Below are instructions on how to create the GCPLoadBal store type manually in the Keyfactor Command Portal

Click to expand manual GCPLoadBal details

Create a store type called GCPLoadBal with the attributes in the tables below:

Basic Tab

Attribute	Value	Description
Name	GCP Load Balancer	Display name for the store type (may be customized)
Short Name	GCPLoadBal	Short display name for the store type
Capability	GCPLoadBal	Store type name orchestrator will register with. Check the box to allow entry of value
Supports Add	✅ Checked	Check the box. Indicates that the Store Type supports Management Add
Supports Remove	✅ Checked	Check the box. Indicates that the Store Type supports Management Remove
Supports Discovery	🔲 Unchecked	Indicates that the Store Type supports Discovery
Supports Reenrollment	🔲 Unchecked	Indicates that the Store Type supports Reenrollment
Supports Create	🔲 Unchecked	Indicates that the Store Type supports store creation
Needs Server	🔲 Unchecked	Determines if a target server name is required when creating store
Blueprint Allowed	🔲 Unchecked	Determines if store type may be included in an Orchestrator blueprint
Uses PowerShell	🔲 Unchecked	Determines if underlying implementation is PowerShell
Requires Store Password	🔲 Unchecked	Enables users to optionally specify a store password when defining a Certificate Store.
Supports Entry Password	🔲 Unchecked	Determines if an individual entry within a store can have a password.

The Basic tab should look like this:

Advanced Tab

Attribute	Value	Description
Supports Custom Alias	Optional	Determines if an individual entry within a store can have a custom Alias.
Private Key Handling	Required	This determines if Keyfactor can send the private key associated with a certificate to the store. Required because IIS certificates without private keys would be invalid.
PFX Password Style	Default	'Default' - PFX password is randomly generated, 'Custom' - PFX password may be specified when the enrollment job is created (Requires the Allow Custom Password application setting to be enabled.)

The Advanced tab should look like this:

For Keyfactor Command versions 24.4 and later, a Certificate Format dropdown is available with PFX and PEM options. Ensure that PFX is selected, as this determines the format of new and renewed certificates sent to the Orchestrator during a Management job. Currently, all Keyfactor-supported Orchestrator extensions support only PFX.

Custom Fields Tab

Custom fields operate at the certificate store level and are used to control how the orchestrator connects to the remote target server containing the certificate store to be managed. The following custom fields should be added to the store type:

Name	Display Name	Description	Type	Default Value/Options	Required
jsonKey	Service Account Key	If authenticating by passing credentials from Keyfactor Command, this is the JSON-based service account key created from within Google Cloud. If authenticating via Application Default Credentials (ADC), select No Value	Secret		✅ Checked

The Custom Fields tab should look like this:

Service Account Key

If authenticating by passing credentials from Keyfactor Command, this is the JSON-based service account key created from within Google Cloud. If authenticating via Application Default Credentials (ADC), select No Value

Installation

1. Download the latest GCP Load Balancer Universal Orchestrator extension from GitHub.

   Navigate to the GCP Load Balancer Universal Orchestrator extension GitHub version page. Refer to the compatibility matrix below to determine the asset should be downloaded. Then, click the corresponding asset to download the zip archive.

   Universal Orchestrator Version	Latest .NET version installed on the Universal Orchestrator server	rollForward condition in Orchestrator.runtimeconfig.json	gcp-loadbalancer-orchestrator .NET version to download
   Older than 11.0.0			net6.0
   Between 11.0.0 and 11.5.1 (inclusive)	net6.0		net6.0
   Between 11.0.0 and 11.5.1 (inclusive)	net8.0	Disable	net6.0
   11.6 and newer	net8.0		net8.0

   Unzip the archive containing extension assemblies to a known location.

   Note If you don't see an asset with a corresponding .NET version, you should always assume that it was compiled for net6.0.

2. Locate the Universal Orchestrator extensions directory.

   • Default on Windows - C:\Program Files\Keyfactor\Keyfactor Orchestrator\extensions
   • Default on Linux - /opt/keyfactor/orchestrator/extensions

3. Create a new directory for the GCP Load Balancer Universal Orchestrator extension inside the extensions directory.

   Create a new directory called gcp-loadbalancer-orchestrator.

   The directory name does not need to match any names used elsewhere; it just has to be unique within the extensions directory.

4. Copy the contents of the downloaded and unzipped assemblies from step 2 to the gcp-loadbalancer-orchestrator directory.

5. Restart the Universal Orchestrator service.

   Refer to Starting/Restarting the Universal Orchestrator service.

6. (optional) PAM Integration

   The GCP Load Balancer Universal Orchestrator extension is compatible with all supported Keyfactor PAM extensions to resolve PAM-eligible secrets. PAM extensions running on Universal Orchestrators enable secure retrieval of secrets from a connected PAM provider.

   To configure a PAM provider, reference the Keyfactor Integration Catalog to select an extension and follow the associated instructions to install it on the Universal Orchestrator (remote).

The above installation steps can be supplemented by the official Command documentation.
