Setting Up Your Environment

The following examples provide a general overview for setting up a service and binding certain tools and applications to the service. These topics are covered in-depth on the Using Crunchy PostgreSQL for PCF page.

In order to start setting up the Crunchy PostgreSQL tools, some environment details will need to be set up.

Initially, make sure you have access to whichever Pivotal Cloud Foundry environment you will be working in. Whomever is your administrator or supervisor should be able to provide you with the web URL and login credentials.

This procedure requires the Cloud Foundry Command Line Interface (cf CLI). To obtain the tool, do the following:

  1. Log in into your Pivotal Apps Manager.
  2. Click on Tools on the left hand side of the screen.
  3. On the screen, you will be provided a download link for the ‘cf cli’ utility for your release.
  4. Download and follow the installation instructions to get it set up.
  5. If you experience any difficulty installing cf CLI, please use reference guide

Using the cf CLI, log into the CF instance you intend to use by running:


Setting Up a Crunchy PostgreSQL Database

To set up a Crunchy PostgreSQL Database:

  1. Log in to Pivotal Apps Manager.
  2. Select the appropriate org on the left-hand side of the screen.
  3. Click Marketplace on the left-hand side of the screen.
  4. From the Marketplace, select the database cluster you wish to use.
  5. Set up the service.
    • Instance Name: The name of your service instance. The name should be short but descriptive. The name should not contain any spaces.
    • Space: The working space for the deployment of the application. If you have a production or development space allocated, this is where the space will be defined. It may be pre-defined depending on the access rights associated with your user account.
    • Bind to App: For this deployment, the service is not bound to any application.
  6. Click Show Advanced Options to add the additional required fields.
  7. Create four additional fields as specified below:
    • db_username: The username associated with the database.
    • db_name: The name of the database.
    • owner_email: The application owner’s email address.
    • owner_name: The application owner’s full name.
    • postgis: Set to true to include PostGIS extensions.
  8. Click Add once all fields have been completed.

Now that the database is set up and running on a service, you must set up service keys. Service keys allow you to access the database with a username and password.

To set up a service key, do the following:

  1. On the left-hand side of your screen, go to the org and spaces under which your service was created.
  2. On the right-hand side of the screen, under the list of services, you should see your newly created service. The second column contains the name you specified in previous steps.
  3. Go to the service.
  4. Go to Overview > Service Key Credentials and click Create Service Key.
  5. Enter the name of the service key.
    • Crunchy Data recommends naming the service key with the same name as your instance, followed by the suffix _sk. For example, if your instance name was test_deployment, then your first service key would be test_deployment_sk.
  6. Click Create. Your service key is created and listed under the service key credentials. Click your service key to see your service credentials.
  7. You will want to save the information on this page temporarily to set up the pgAdmin instance as well as the PostgreSQL Tools.

Crunchy pgAdmin4

To administer the database using the pgAdmin web interface, do the following:

  1. Open up the manifest.yml file in an editor and change the following values:
    • name: The name of the app deployment. It should be unique to the environment and not previously used.
    • memory: 256 MB of memory should be sufficient to run this application.
    • disk_quota: 1 GB of disk space should accommodate the setup.
  2. Save the file.
  3. Open the file in an editor and change the following values:
    • PGADMIN_SETUP_EMAIL: The email user account you use to log in to the pgAdmin interface. Crunchy Data recommends using the same email address you used in the database setup steps.
    • PGADMIN_SETUP_PASSWORD: The password used to access the pgAdmin interface.
  4. Go the crunchy-pgadmin directory by running cd ~/crunchy-pgadmin.
  5. Push the app up to the Pivotal Cloud Foundry area by running cf push.

To set up the pgAdmin interface to communicate with the database, do the following:

  1. In Apps Manager, on the left, select the org and spaces in which your app was deployed.
  2. On the right-hand side of the screen, you should now see your app name.
  3. Below the app name, you should see the word Running in green letters indicating that the app is running properly. If it is not, reach out to Crunchy Data for assistance.
  4. Click on the app.
  5. In the details of the app, go to the Route tab.
  6. Under the Route tab is a URL to your running pgAdmin interface. Save this URL.
  7. Open the URL in a separate browser window or tab.
  8. The login credentials are the email address and password you specified in in the previous section.

To set up access to your previously created database, do the following:

  1. Right-click on Servers on the left and select Create Server from the dropdown.
  2. Under General, complete the following fields:

    • Name: This name should match the name of the database instance created.
    • Server Group: Select the Servers group.
    • Connect Now: Leave this checkbox enabled.
    • Comments: This is for details regarding the setup of this connection, such as brief summary of the database you are connecting to and its purpose.
  3. Under Connection, complete the following fields:

    • Host name/address: Use the IP address provided by the service key.
    • Port: Leave as 5432.
    • Maintenance DB: Use the database name provided by the service key.
    • User Name: Use the username provided by the service key.
    • Password: Use the password provided by the service key.
    • Save Password: Enable this checkbox.
    • Role: Leave this field blank.
  4. Click Save.

You should now be able to view your database and have the standard PostgreSQL administrator tools at your disposal.
