Lab 3: Deploy Postgres via Operator

In this lab you'll deploy Postgres and set up a database which is used by the 'Articles' service.

Step 1: Create Project

In the Cloud Shell enter the following command.

$ oc new-project postgres

Step 2: Install the Postgres Operator

Open the OperatorHub page and filter by 'postgres'. Open the operator 'PostgreSQL Operator by Dev4devs.com'.

Click 'Install'.

Create a subscription. Make sure your new project 'postgres' is selected in the combobox.

Step 3: Create the Database

Click on the operator.

Click on 'Create Instance' in the 'Database Database' box.

Edit the yaml. The database name needs to be changed to 'database-articles'. The namespace should be 'postgres' by default. After this click 'Create'.

Step 4: Verify the Installation

On the 'Pods' page select the project 'postgres'. Make sure the pod 'database-articles....' is running.
