Cloud Foundry for Developers

By: Rahul Kumar Jain, Rick Farmer, David Wu

Overview of this book

Cloud Foundry is the open source platform to deploy, run, and scale applications. Cloud Foundry is growing rapidly and a leading product that provides PaaS (Platform as a Service) capabilities to enterprise, government, and organizations around the globe. Giants like Dell Technologies, GE, IBM, HP and the US government are using Cloud Foundry innovate faster in a rapidly changing world. Cloud Foundry is a developer’s dream. Enabling them to create modern applications that can leverage the latest thinking, techniques and capabilities of the cloud, including: ? DevOps ? Application Virtualization ? Infrastructure agnosticism ? Orchestrated containers ? Automation ? Zero downtime upgrades ? A/B deployment ? Quickly scaling applications out or in This book takes readers on a journey where they will first learn the Cloud Foundry basics, including how to deploy and scale a simple application in seconds. Readers will build their knowledge of how to create highly scalable and resilient cloud-native applications and microservices running on Cloud Foundry. Readers will learn how to integrate their application with services provided by Cloud Foundry and with those external to Cloud Foundry. Readers will learn how to structure their Cloud Foundry environment with orgs and spaces. After that, we’ll discuss aspects of continuous integration/continuous delivery (CI/CD), monitoring and logging. Readers will also learn how to enable health checks, troubleshoot and debug applications. By the end of this book, readers will have hands-on experience in performing various deployment and scaling tasks. Additionally, they will have an understanding of what it takes to migrate and develop applications for Cloud Foundry.

Preface

Pushing your first application to Cloud Foundry


In order to have applications running on Cloud Foundry, we must first be able to deploy them on Cloud Foundry. Colloquially, push it to the cloud is what you will hear and read to denote deploying the application to the cloud. The magic command to do this is:

 cf push 

That's it! There are of course a number of parameters that you will need, such as specifying the application name and perhaps other settings that may be needed for the application to run. However, before proceeding to push an application to Cloud Foundry, there are a number of prerequisites that must be fulfilled beforehand.

What you need before you push

The important minimum prerequisites before you push an application to Cloud Foundry are:

  1. Ensure your application is supported by Cloud Foundry and/or has the necessary buildpack.
  2. Ensure your application is Cloud Ready. While this is not strictly necessary, it will make starting development on the cloud easier by preventing occurrences...
