Manage certificates

This page describes how to use Certificate Manager to create and manage Transport Layer Security (TLS) (SSL) certificates. Certificate Manager supports the following types of TLS (SSL) certificates:

  • Google-managed certificates are certificates that Google Cloud obtains and manages for you. You can create the following types of Google-managed certificates with Certificate Manager:
    • Global certificates
      • Google-managed certificates with load balancer authorization
      • Google-managed certificates with DNS authorization
      • Google-managed certificates with Certificate Authority Service (CA Service)
    • Regional certificates
      • Regional Google-managed certificates
      • Regional Google-managed certificates with CA Service
  • Self-managed certificates are certificates that you obtain, provision, and renew yourself.

For more information about certificates, see How Certificate Manager works.

To learn how to deploy a certificate with Certificate Manager, see Deployment overview.

Configure CA Service integration with Certificate Manager

If you have not already done so, you must configure Certificate Manager to integrate with CA Service as described in this section. If a certificate issuance policy is in effect on the target CA pool, certificate provisioning might fail for one of the following reasons:

  • The certificate issuance policy has blocked the requested certificate. In this case, you are not billed because the certificate has not been issued.
  • The policy has applied changes to the certificate that are not supported by Certificate Manager. In this case, you are still billed because the certificate has been issued, even if it is not fully compatible with Certificate Manager.

For any problems related to issuance policy restrictions, see the Troubleshooting page.

To configure CA Service integration with Certificate Manager, do the following:

  1. Grant Certificate Manager the ability to request certificates from the target CA pool:

    1. Use the following command to create a Certificate Manager service account in the target Google Cloud project:

      gcloud beta services identity create --service=certificatemanager.googleapis.com \
  --project=PROJECT_ID

      Replace PROJECT_ID with the ID of the target Google Cloud project.

      The command returns the name of the created service account. For example:

      service-520498234@gcp-sa-certificatemanager.iam.gserviceaccount.com

    2. Grant the Certificate Manager service account the Certificate Requester role within the target CA pool as follows:

      gcloud privateca pools add-iam-policy-binding CA_POOL \
    --location REGION \
    --member="serviceAccount:SERVICE_ACCOUNT" \
    --role roles/privateca.certificateRequester

      Replace the following:

      • CA_POOL: the ID of the target CA pool
      • REGION: the target Google Cloud region

  7. In the Rotation window percentage, specify the percentage of the certificate's lifetime when its renewal process begins. To find the range of valid values, see Lifetime and Rotation window percentage.

  8. From the Key algorithm list, select the key algorithm to use when generating the private key.

  9. From the CA pool list, select the name of the CA pool to assign to this certificate issuance config.

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

  11. Click Create.

gcloud 

 gcloud certificate-manager issuance-configs create ISSUANCE_CONFIG_NAME \
     --ca-pool=CA_POOL \
     [--lifetime=CERTIFICATE_LIFETIME] \
     [--rotation-window-percentage=ROTATION_WINDOW_PERCENTAGE] \

List certificates

To list certificates managed by Certificate Manager, complete the steps in this section. For example, you can perform the following queries:

  • List certificates by their assigned domain names
  • List certificates that have expired

To complete this task, you must have one of the following roles on the target Google Cloud project:

  • Certificate Manager Viewer
  • Certificate Manager Editor
  • Certificate Manager Owner

For more information, see Roles and permissions.

Console

If you have more than 10,000 certificates in your project that are managed by Certificate Manager, the Certificate Manager page in the Google Cloud console cannot list them. In such cases, use the gcloud CLI command to list your certificates instead.

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

    Go to Certificate Manager

  2. On the page that appears, select the Certificates tab. This tab lists all of the certificates managed by Certificate Manager in the selected project.

The Classic Certificates tab lists certificates in the selected project that have been provisioned directly through Cloud Load Balancing. These certificates are not managed by Certificate Manager. For instructions about managing those certificates, see one of the following articles in the Cloud Load Balancing documentation:

gcloud 

gcloud certificate-manager certificates list \
    [--location="REGION"] \
    --filter="FILTER" \
    --page-size="PAGE_SIZE" \
    --limit="LIMIT" \
    --sort-by="SORT_BY"

Replace the following:

  • REGION: the target Google Cloud region; to list certificates from all regions, use - as the value. The default is global. This setting is optional.
  • FILTER: an expression that constrains the returned results to specific values. For example, you can filter results by the following criteria:
    • Expiration time: --filter='expire_time >= "2021-09-01T00:00:00Z"'
    • SAN DNS names: --filter='san_dnsnames:"example.com"'
    • Certificate state: --filter='managed.state=FAILED'
    • Certificate type: --filter='managed:*'
    • Labels and creation time: --filter='labels.key:value AND create_time > "2021-09-01T00:00:00Z"'

For more filtering examples that you can use with Certificate Manager, see Sorting and filtering list results in the Cloud Key Management Service documentation.

  • PAGE_SIZE: the number of results to return per page.
  • LIMIT: the maximum number of results to return.
  • SORT_BY: a comma-delimited list of name fields by which the returned results are sorted. The default sort order is ascending; for descending sort order, prefix the field with ~.

API

List the certificates by making a LIST request to the certificates.list method as follows:

GET /v1/projects/PROJECT_ID/locations/REGION/certificates?filter=FILTER&pageSize=PAGE_SIZE&sortBy=SORT_BY

Replace the following:

  • REGION: the target Google Cloud region; to list certificates from all regions, use - as the value.
  • PROJECT_ID: the ID of the target Google Cloud project.
  • FILTER: an expression that constrains the returned results to specific values.
  • PAGE_SIZE: the number of results to return per page.
  • SORT_BY: a comma-delimited list of field names by which the returned results are sorted. The default sort order is ascending; for descending sort order, prefix the field with ~.

View the state of a certificate
