Written by

Updated at October 17, 2024

Certificate Manager does not manage custom certificates. To make your certificate continuously available to your resources, be sure to renew it on time.

To get a new version of a user certificate:

Management console

CLI

Terraform

API

In the management console, select the folder the certificate was added to.
In the list of services, select Certificate Manager.
Select the certificate you want to renew in the list.
In the window that opens, click Renew certificate.
In the window that opens, click Add certificate in the Certificate field.
1. Choose how to add it: File or Text.
2. Click Add.
In the Intermediate certificate chain field, click Add chain.
1. Choose how to add it: File or Text.
2. Click Add.
In the Private key field, click Add private key.
1. Choose how to add it: File or Text.
2. Click Add.
Click Update.

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.

yc certificate-manager certificate update --help

View the list of certificates:

yc certificate-manager certificate list

Result:

+----------------------+--------+-------------+---------------------+----------+--------+
|          ID          |  NAME  |   DOMAINS   |      NOT AFTER      |   TYPE   | STATUS |
+----------------------+--------+-------------+---------------------+----------+--------+
| fpqmg47avvim******** | mycert | example.com | 2021-09-15 06:48:26 | IMPORTED | ISSUED |
+----------------------+--------+-------------+---------------------+----------+--------+

Run this command:

yc certificate-manager certificate update \
  --id fpqmg47avvim******** \
  --chain myupdatedcert.pem \
  --key myupdatedkey.pem

Where:

--id: ID of the certificate to renew.
--chain: Path to the new certificate chain file.
--key: Path to the file of the new certificate private key.

Result:

id: fpqmg47avvim********
folder_id: b1g7gvsi89m3********
created_at: "2020-09-15T06:54:44.916Z"
...
issued_at: "2020-09-15T08:23:50.147668Z"
not_after: "2021-09-15T08:12:57Z"
not_before: "2020-09-15T08:12:57Z"

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

Open the Terraform configuration file and change the certificate and private_key parameters of the certificate:

Sample certificate description in the Terraform configuration

...
resource "yandex_cm_certificate" "imported-certificate" {
  name        = "my-certificate"
  description = "this is a test certificate"

  self_managed {
    certificate = <<-EOT
                  -----BEGIN CERTIFICATE-----
                  MIIF...
                  -----END CERTIFICATE-----
                  EOT
    private_key = <<-EOT
                  -----BEGIN PRIVATE KEY-----
                  MIIJ...
                  -----END PRIVATE KEY-----
                  EOT
  }
}
...

Apply the changes:
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.

You can check the certificate update using the management console or this CLI command:

yc certificate-manager certificate get <certificate_name>

To renew a certificate, use the update REST API method for the Certificate resource or the CertificateService/Update gRPC API call.
