Adding a Let's Encrypt® certificate

If you do not have the Yandex Cloud CLI yet, install and initialize it.

The folder used by default is the one specified when creating the CLI profile. To change the default folder, use the yc config set folder-id <folder_ID> command. You can also specify a different folder for any command using --folder-name or --folder-id. If you access a resource by its name, the search will be limited to the default folder. If you access a resource by its ID, the search will be global, i.e., through all folders based on access permissions.

1. View the command description:

   yc certificate-manager certificate request --help
   

2. Run this command:

   yc certificate-manager certificate request \
     --name mymanagedcert \
     --domains example.com
   

   Where:

   • --name: Certificate name
   • --domains: Certificate domains

   Result:

   id: fpq6gvvm6piu********
   folder_id: b1g7gvsi89m3********
   created_at: "2020-09-15T08:49:11.533771Z"
   ...
   - example.com
   status: VALIDATING
   updated_at: "2020-09-15T08:49:11.533771Z"
   

If you do not have Terraform yet, install it and configure the Yandex Cloud provider.

To manage infrastructure using Terraform under a service account or user accounts (a Yandex account, a federated account, or a local user), authenticate using the appropriate method.

1. In the Terraform configuration file, describe the resource you want to create:

   resource "yandex_cm_certificate" "le-certificate" {
     name    = "<certificate_name>"
     domains = ["<domain>"]
   
     managed {
     challenge_type = "<check_type>"
     }
   }
   

   Where:

   • domains: List of domains you need to create a certificate for.
   • challenge_type: Type of domain ownership verification the domain owner has to pass. The possible values are:
     • DNS_CNAME: Create a DNS record in CNAME format with the specified value. We recommend this method for automatic certificate renewal.
     • DNS_TXT: Create a DNS record in TXT format with the specified value.
     • HTTP: Place the specified value in the specified URL.

   For more on the properties of the yandex_cm_certificate resource, see this provider guide.

2. Create the resources:

   1. In the terminal, navigate to the configuration file directory.

   2. Make sure the configuration is correct using this command:

      terraform validate
      

      If the configuration is valid, you will get this message:

      Success! The configuration is valid.
      

   3. Run this command:

      terraform plan
      

      You will see a list of resources and their properties. No changes will be made at this step. Terraform will show any errors in the configuration.

   4. Apply the configuration changes:

      terraform apply
      

   5. Type yes and press Enter to confirm the changes.

This will create a certificate in the specified folder. You can check the new certificate and its settings using the management console or this CLI command:

yc certificate-manager certificate get <certificate_name>

To add a certificate, use the requestNew REST API method for the Certificate resource or the CertificateService/RequestNew gRPC API call.
