Overview of this book

Google Cloud Platform is one of the three major cloud providers in the industry, exhibiting great leadership in application modernization and data management. This book provides a comprehensive introduction for those who are new to cloud development and shows you how to use the tools to create cloud-native applications by integrating the technologies used by Google. The book starts by taking you through the basic programming concepts and security fundamentals necessary for developing in Google Cloud. You'll then discover best practices for developing and deploying applications in the cloud using different components offered by Google Cloud Platform such as Cloud Functions, Google App Engine, Cloud Run, and other GCP technologies. As you advance, you'll learn the basics of cloud storage and choosing the best options for storing different kinds of data as well as understand what site reliability engineers do. In the last part, you'll work on a sample case study of Hip Local, a community application designed to facilitate communication between people nearby, created by the Google Cloud team. By the end of this guide, you'll have learned how to design, develop, and deploy an end-to-end application on the Google Cloud Platform.

The full deployment life cycle of an application on Google Kubernetes Engine and Cloud Run

Now that we have reviewed the basic concepts of Kubernetes, GKE, and Cloud Run, it is possible to explore the steps needed to deploy an application and how to expose it to the internet to be consumed by either users or other applications.

Building a container image using Cloud Build

The first thing we need to do to deploy an application in a cluster created in GKE or in Cloud Run is to create an image of a container of our application. For this, our application must have previously created its Dockerfile. By having the Google SDK installed in our local environment or by using Cloud Shell, we can use Cloud Build to generate our image and upload it directly to the GCP image repository called Google Container Registry.

To build the image, we use the following command, assuming that we are at the root of the project where the Dockerfile is located:

gcloud build submit –tag gcr...
