Manage SSL/TLS certificates

MySQL   |  PostgreSQL   |  SQL Server

This page describes how to manage your client and server CA certificates.

Manage client certificates

Use the following procedures to manage client certificates in Cloud SQL.

Retrieve a client certificate

You can retrieve the public key portion of a client certificate. You cannot retrieve the private key, however. If you have lost your private key, you must create a new certificate.

Console

1. In the Google Cloud console, go to the Cloud SQL Instances page.

   Go to Cloud SQL Instances

2. To open the Overview page of an instance, click the instance name.
3. Select Connections from the SQL navigation menu.
4. Select the Security tab.
5. In Manage client certificates, click a certificate name.
6. The SSL Client Certificate page opens and shows the client certificate (client-cert.pem) with a link to download the certificate.

gcloud

Retrieve the client certificate public key with the ssl client-certs describe command:

gcloud sql ssl client-certs describe CERT_NAME \
--instance=INSTANCE_NAME \
--format="value(cert)" > client-cert.pem

REST v1

1. List the certificates on the instance to get the fingerprint of the certificate you want to retrieve:

   Before using any of the request data, make the following replacements:

   • project-id: The project ID
   • instance-id: The instance ID

   HTTP method and URL:

   GET https://sqladmin.googleapis.com/v1/projects/project-id/instances/instance-id/sslCerts

   To send your request, expand one of these options:

   curl (Linux, macOS, or Cloud Shell)

   Note: The following command assumes that you have logged in to the gcloud CLI with your user account by running gcloud init or gcloud auth login , or by using Cloud Shell, which automatically logs you into the gcloud CLI . You can check the currently active account by running gcloud auth list.

   Execute the following command:

   curl -X GET \
        -H "Authorization: Bearer $(gcloud auth print-access-token)" \
        "https://sqladmin.googleapis.com/v1/projects/project-id/instances/instance-id/sslCerts"

   PowerShell (Windows)

   Note: The following command assumes that you have logged in to the gcloud CLI with your user account by running gcloud init or gcloud auth login . You can check the currently active account by running gcloud auth list.

   Execute the following command:

   $cred = gcloud auth print-access-token
   $headers = @{ "Authorization" = "Bearer $cred" }
   
   Invoke-WebRequest `
       -Method GET `
       -Headers $headers `
       -Uri "https://sqladmin.googleapis.com/v1/projects/project-id/instances/instance-id/sslCerts" | Select-Object -Expand Content

Manage server CA certificates

Rotate server CA certificates

If you've received a notice about your certificates expiring, or you have initiated a rotation, then you must take the following steps to complete the rotation:

1. Download the new server CA certificate information.
2. Update your clients to use the new server CA certificate information.
3. Complete the rotation, which moves the active certificate into the "previous" slot and updates the newly added certificate to be the active certificate.

After rotating the SSL certificate, your App Engine and Cloud SQL Auth Proxy connections will automatically receive a new certificate when they connect.

Console

Download the new server CA certificate information:

1. In the Google Cloud console, go to the Cloud SQL Instances page.

   Go to Cloud SQL Instances

2. To open the Overview page of an instance, click the instance name.
3. Select Connections from the SQL navigation menu.
4. Select the Security tab.
5. Click to expand Manage certificates.
6. Select Rotate CA certificate.

   If there are no eligible certificates, then the rotate option is unavailable.

7. Click Download Certificates.

The server CA certificate information, encoded as a PEM file, is downloaded to your local environment:

• Update all of your PostgreSQL clients to use the new information by copying the downloaded file to your client host machines, replacing the existing server-ca.pem file.

After you have updated your clients, complete the rotation:

1. Return to the Security tab.
2. Click to expand Manage certificates.
3. Select Rotate CA certificate.
4. Confirm that your clients are connecting properly.

   If any clients are not connecting using the newly rotated certificate, then you can select Rollback CA certificate to rollback to the previous configuration.

gcloud

1. Create a server CA certificate:

   gcloud beta sql ssl server-ca-certs create \
   --instance=INSTANCE
   

2. Download the certificate information to a local PEM file:

   gcloud beta sql ssl server-ca-certs list \
   --format="value(cert)" \
   --instance=INSTANCE_NAME > \
   FILE_PATH/FILE_NAME.pem
   

3. Update all of your clients to use the new information by copying the downloaded file to your client host machines, replacing the existing server-ca.pem files.
4. After you have updated your clients, complete the rotation:

   gcloud beta sql ssl server-ca-certs rotate \
   --instance=INSTANCE_NAME
         

5. Confirm that your clients are connecting properly.

   If any clients are not connecting using the newly rotated certificate, then you can rollback to the previous configuration.

Roll back a certificate rotation operation

After you complete a certificate rotation, your clients must all use the new certificate to connect to your Cloud SQL instance. If the clients aren't updated properly to use the new certificate information, then they can't connect using SSL/TLS to your instance. If this happens, then you can roll back to the previous certificate configuration.

A rollback operation moves the active certificate into the "upcoming" slot (replacing any "upcoming" certificate). The "previous" certificate becomes the active certificate, returning your certificate configuration to the state it was in before you completed the rotation.

Note: Certificate rollback is available only until the old certificate expires.

To roll back to the previous certificate configuration:

Console

1. In the Google Cloud console, go to the Cloud SQL Instances page.

   Go to Cloud SQL Instances

2. To open the Overview page of an instance, click the instance name.
3. Select Connections from the SQL navigation menu.
4. Select the Security tab.
5. Click to expand Manage certificates.
6. Select Rollback CA certificate.

   If there are no eligible certificates, then the rollback option is unavailable. Otherwise, the rollback action completes after a few seconds.

Initiate a rotation

You don't need to wait for the email from Cloud SQL to start a rotation. You can start one at any time. When you start a rotation, a new certificate is created and placed into the "upcoming" slot. If a certificate is already present in the "upcoming" slot at the time of your request, then that certificate is deleted. There can be only one upcoming certificate.

To initiate a rotation:

Console
