Challenge 04 - Storage

< Previous Challenge - Home - Next Challenge >

Introduction

In the previous challenge, we discovered that our application is not connected to any database, so in this challenge, we will be learning how to deploy a MongoDB database onto ARO so that our application can have persistent data.

Description

In this challenge we will deploy a MongoDB database service. We will be using the OpenShift CLI to deploy a bitnami/mongodb container image from Docker Hub.

The database should have the following variables:

  MONGODB_USERNAME=ratingsuser
  MONGODB_PASSWORD=ratingspassword
  MONGODB_DATABASE=ratingsdb
  MONGODB_ROOT_USER=root
  MONGODB_ROOT_PASSWORD=ratingspassword

Finally, once this has been deployed, you will also need to retrieve each service’s hostname (the MongoDB and the rating-api) in order to complete the next challenge.

Success Criteria

To complete this challenge successfully, you should be able to:

• Successfully deploy the MongoDB service
• Verify successful deployment by checking the application status
• Identify the MongoDB service’s hostname and have it written down or stored somewhere for the next challenge
• Identify the rating-api service’s hostname and have it written down or stored somewhere for the next challenge
