AWS Certificate Manager

[edit on GitHub]

This page explains how to use the AWS Certificate Manager (ACM) console to generate a public ACM certificate to create a Load Balancer (LB).

You can either generate a new public certificate or copy an existing Amazon Resource Name (ARN) value of the certificate of your selected region in the AWS console.

Requesting a Public Certificate using AWS console

Follow these steps if you want to request an ACM public certificate:

1. Sign in to the AWS Management Console.

2. Open the ACM console.

3. Select your region from the top-right corner of the console.

4. Select Request a certificate.

5. Select the Request a public certificate option from the Certificate type page, and select Next.

6. In the Domain names section, enter your domain name. You can use a fully qualified domain name (FQDN), such as www.example.com, or a bare domain name such as example.com.

7. In the Select validation method section, select either DNS validation or Email validation.

8. From the Tags page, tag your certificate. Tags are key-value pairs that serve as metadata for identifying and organizing AWS resources.

9. Select Request. The console returns you to your certificate list after processing the request, where your new certificate displays with status, Pending validation.

You can also request a public certificate using the Command Line Interface (CLI). For detailed information on requesting these certificates, refer AWS documentation on requesting a public certificate.

Providing Certificate ARN Value in a2ha.rb Configuration file

Follow these steps if you want to use the AWS certificates in your network infrastructure:

1. Log in as a Sudo user by using su- command.

2. Navigate to the hab workspace directory.

3. Open the a2ha.rb file in any editor you like.

4. Copy the existing or generated ARN value from AWS console to the chef_server_lb_certificate_arn and automate_server_lb_certificate_arn fields in the a2ha.rb file.

5. Save and close the file.
