Configure a State Database

This section describes how to associate Cloud Service Broker for GCP with a MySQL database, the state database.

About Encrypting the State Database

In production environments, VMware recommends that you enable encryption. This encrypts certain sensitive information in the state database, such as IaaS credentials. The encryption password that you enter on the Service Broker Config pane is used to generate an encryption key.

Important

VMware recommends that backup and restore capabilities are enabled in the MySQL database before attempting encryption.

Applying changes takes longer than normal when you first enable encryption and when you change the encryption password.

Prerequisite

You must have a small MySQL database to use as the state database.

Procedure: Configure a State Database

To configure Cloud Service Broker for GCP with a database:

  1. Click Service Broker Config.

    Fields for configuring the service broker. See the following steps for detailed descriptions of the configurable fields.

  2. Configure the fields as follows:

    Field Instructions
    Memory limit Memory limit (for example, 1024M, 2G) for the Service Broker app defaults to 2G.
    Disk limit Disk limit (for example, 1024M, 2G) for the Service Broker app defaults to 2G.
    Database host Enter the host name of the prerequisite state database.
    Database username and Database password Enter the credentials for the state database. The example shown in the screenshot in the previous step refers to setting the username for a MySQL tile provisioned database. If you are configuring a database provisioned by another service, refer to the documentation for that service for the correct username format. For Cloud SQL for MySQL, see the Google Cloud documentation.
    Database port Enter the port number for connection to the state database. It is 3306 by default.
    Database name Enter the name of an existing database to use as the state database.
    TLS Enforcement Select the type of TLS enforcement you want. If you select Custom, enter your CA certificate, client certificate, and key.
    Enable encryption of the Cloud Service Broker database If you want the sensitive data to be encrypted, select this checkbox and the Add button. If you do not want to encrypt the date, leave the checkbox unselected and do not fill in the Database Encryption Passwords fields.
    Label Enter a unique password label. You cannot change this label after you save.
    Password Enter a secure password that is at least 20 characters long. You cannot change this password after you save.
    Primary Select this checkbox if this is the password that you want to use to encrypt the data. You must mark one and only one password as primary.

  3. Click Save.

  4. If upgrading from a previous tile version, service instances might need upgrading. By default, the tile upgrades all instances during installation.

Upgrade All Services Instances Config

If upgrading from a previous tile version, service instances might need upgrading. By default, the tile upgrades all instances during installation. This section is about the general configuration of upgrades. For version-specific upgrade instructions, see Upgrading Cloud Service Broker for GCP.

If Upgrade all services is unchecked, service instances are not upgraded during installation. The broker might not be able to manage these service instances anymore. In that case, any operations on that instance (update/bind/unbind/delete) are blocked until the upgrade is performed. You can run the upgrade task any time.

Deleting custom plans before upgrading all instances might cause some instances to become unmanageable by the broker. Delete plans at a later step or see Release Notes for Cloud Service Broker for GCP and Upgrading Cloud Service Broker for GCP to ensure there are no conflicting upgrades.

Instances that the broker has subsumed must be changed to a suitable plan, other than the subsume plan, before performing any upgrades. Failure to do so causes the broker to become unable to manage those instances anymore.

To perform the upgrade task:

  1. Go to the Upgrade All Service Instances Config tab.

    Fields for configuring Upgrade All Service Instances task. See the following steps for detailed descriptions of the configurable fields.

  2. Configure the fields as follows:

    Field Description
    Upgrade all services Enabled by default. Indicates if service instances are upgraded during product installation.
    The number of upgrades to run in parallel Indicates the number of instances that can be in the upgrading status at any given time.

  3. Click Save.

  4. Return to the Tanzu Operations Manager Installation Dashboard.

  5. Click Review Pending Changes.

  6. Click Apply changes to install the Cloud Service Broker for GCP tile.
