Adding a Let's Encrypt® certificate

If you do not have the Yandex Cloud command line interface yet, install and initialize it.

The folder specified in the CLI profile is used by default. You can specify a different folder using the --folder-name or --folder-id parameter.

1. View a description of the command:

   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 don't have Terraform, install it and configure the Yandex Cloud provider.

1. In the Terraform configuration file, describe the parameters of the resource to create:

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

   Where:

   • domains: List of domains to create a certificate for.
   • challenge_type: Type of domain rights check the domain owner should pass. The possible values include:
     • DNS_CNAME: Create a DNS record in CNAME format with the specified value. This method is recommended 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 information about the yandex_cm_certificate resource parameters, see the Terraform provider documentation.

2. Create resources:

   1. In the terminal, change to the folder where you edited the configuration file.

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

      terraform validate
      

      If the configuration is correct, the following message is returned:

      Success! The configuration is valid.
      

   3. Run the command:

      terraform plan
      

      The terminal will display a list of resources with parameters. No changes are made at this step. If the configuration contains errors, Terraform will point them out.

   4. Apply the configuration changes:

      terraform apply
      

   5. Confirm the changes: type yes in the terminal and press Enter.

A certificate will then be created in the specified folder. You can check the new certificate and its configuration 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.
