Deploy a regional self-managed certificate

---

This tutorial shows you how to use Certificate Manager to deploy a self-managed certificate to a regional external Application Load Balancer or to a regional internal Application Load Balancer.

If you want to deploy to global external or cross-region load balancers, see the following:

• Deploy a global external self-managed certificate
• Deploy a cross-region self-managed certificate

Objectives

This tutorial shows you how to complete the following tasks:

• Upload a self-managed certificate to Certificate Manager.

• Deploy the certificate to a regional external Application Load Balancer or to a regional internal Application Load Balancer by using a target HTTPS proxy.

Before you begin

1. Sign in to your Google Cloud account. If you're new to Google Cloud, create an account to evaluate how our products perform in real-world scenarios. New customers also get $300 in free credits to run, test, and deploy workloads.

2. In the Google Cloud console, on the project selector page, select or create a Google Cloud project.

   Note: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project. After you finish these steps, you can delete the project, removing all resources associated with the project.

   Go to project selector

3. Make sure that billing is enabled for your Google Cloud project.

4. Enable the Compute Engine, Certificate Manager APIs.

   Enable the APIs

5. Install the Google Cloud CLI.

6. To initialize the gcloud CLI, run the following command:

   gcloud init

   Note: If you installed the gcloud CLI previously, make sure you have the latest version by running gcloud components update.

7. In the Google Cloud console, on the project selector page, select or create a Google Cloud project.

   Note: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project. After you finish these steps, you can delete the project, removing all resources associated with the project.

   Go to project selector

8. Make sure that billing is enabled for your Google Cloud project.

9. Enable the Compute Engine, Certificate Manager APIs.

10. Install the Google Cloud CLI.

11. To initialize the gcloud CLI, run the following command:

    gcloud init

    Note: If you installed the gcloud CLI previously, make sure you have the latest version by running gcloud components update.

Required roles

Make sure that you have the following roles to complete the tasks in this tutorial:

• Certificate Manager Owner (roles/certificatemanager.owner): Required to create and manage Certificate Manager resources.
• Compute Load Balancer Admin (roles/compute.loadBalancerAdmin) or Compute Network Admin (roles/compute.networkAdmin): Required to create and manage HTTPS target proxy.

For more information, see the following:

• Roles and permissions for Certificate Manager.
• Compute Engine IAM roles and permissions for Compute Engine.

Note: If you aren't assigned the permissions or roles, request the missing roles from the Identity and Access Management (IAM) administrator who has the Project IAM Admin role (roles/resourcemanager.projectIamAdmin).

Create the load balancer

This tutorial assumes that you've already created and configured the load balancer's backends, health checks, backend services, and URL maps. Make a note of the URL map's name because you need it later in this tutorial.

• To create a regional external Application Load Balancer, see Set up a regional external Application Load Balancer with VM instance group backends.

• To create a regional internal Application Load Balancer, see Set up a regional internal Application Load Balancer with VM instance group backends.

Create a private key and certificate

To create a private key and a certificate, do the following:

1. Use a trusted third-party certificate authority (CA) to issue the certificate along with its associated key.

2. Verify that the certificate is properly chained and root-trusted.

3. Prepare the following PEM-encoded files:

   • The certificate file (CRT)
   • The corresponding private key file (KEY)

For information about how to request and validate a certificate, see Create a private key and certificate.

Upload a self-managed certificate to Certificate Manager

To upload the certificate to Certificate Manager, do the following:

Console

1. In the Google Cloud console, go to the Certificate Manager page.

   Go to Certificate Manager

2. On the Certificates tab, click Add Certificate.

3. In the Certificate name field, enter a unique name for the certificate.

4. Optional: In the Description field, enter a description for the certificate. The description lets you identify the certificate.

5. For Location, select Regional.

6. From the Region list, select your region.

7. For Certificate type, select Create self-managed certificate.

8. For the Certificate field, do either of the following:

   • Click the Upload button and select your PEM-formatted certificate file.
   • Copy and paste the contents of a PEM-formatted certificate. The contents must start with -----BEGIN CERTIFICATE----- and end with -----END CERTIFICATE-----.

9. For the Private key certificate field, do either of the following:

   • Click the Upload button and select your private key. Your private key must be PEM-formatted and not protected with a passphrase.
   • Copy and paste the contents of a PEM-formatted private key. The private keys must start with -----BEGIN PRIVATE KEY----- and end with -----END PRIVATE KEY-----.

10. In the Labels field, specify labels to associate with the certificate. To add a label, click Add label, and specify a key and a value for your label.

11. Click Create.

    The new certificate appears in the list of certificates.

gcloud

To create a regional self-managed certificate, run the certificate-manager certificates create command:

gcloud certificate-manager certificates create CERTIFICATE_NAME \
    --certificate-file="CERTIFICATE_FILE" \
    --private-key-file="PRIVATE_KEY_FILE" \
    --location="LOCATION"

Replace the following:

• CERTIFICATE_NAME: the name of the certificate.
• CERTIFICATE_FILE: the path and filename of the CRT certificate file.
• PRIVATE_KEY_FILE: the path and filename of the KEY private key file.
• LOCATION: the target Google Cloud location.

Terraform

To upload a self-managed certificate, you can use a google_certificate_manager_certificate resource with the self_managed block.

API

Upload the certificate by making a POST request to the certificates.create method as follows:

POST /v1/projects/PROJECT_ID/locations/LOCATION/certificates?certificate_id=CERTIFICATE_NAME
{
  self_managed: {
    pem_certificate: "PEM_CERTIFICATE",
    pem_private_key: "PEM_KEY",
  }
}

Replace the following:

• PROJECT_ID: the ID of the Google Cloud project.
• CERTIFICATE_NAME: the name of the certificate.
• PEM_CERTIFICATE: the certificate PEM.
• PEM_KEY: the key PEM.
• LOCATION: the target Google Cloud location.

Deploy the self-managed certificate to a load balancer

To deploy the self-managed certificate, attach it directly to the target proxy.

Attach the certificate directly to the target proxy

You can attach the certificate to a new target proxy or an existing target proxy.

To attach the certificate to a new target proxy, use the gcloud compute target-https-proxies create command:

gcloud compute target-https-proxies create PROXY_NAME \
    --certificate-manager-certificates=CERTIFICATE_NAME \
    --url-map=URL_MAP \
    --region=LOCATION

Replace the following:

• PROXY_NAME: the name of the target proxy.
• CERTIFICATE_NAME: the name of the certificate.
• URL_MAP: the name of the URL map. You created the URL map when you created the load balancer.
• LOCATION: the target Google Cloud location where you want to create the HTTPS target proxy.

To attach certificate to an existing target HTTPS proxy, use the gcloud compute target-https-proxies update command. If you don't know the name of the existing target proxy, go to the Target proxies page and note the name of the target proxy.

gcloud compute target-https-proxies update PROXY_NAME \
    --region=LOCATION \
    --certificate-manager-certificates=CERTIFICATE_NAME

After creating or updating the target proxy, run the following command to verify it:

gcloud compute target-https-proxies list

Clean up

To avoid incurring charges to your Google Cloud account for the resources used in this tutorial, delete the uploaded certificate:

gcloud certificate-manager certificates delete CERTIFICATE_NAME

Replace CERTIFICATE_NAME with the name of the target certificate.

If you don't plan to use the load balancer, delete the load balancer and its resources. See Clean up a load balancing setup.
