Overview of this book

Reliable automation is crucial for any code change going into production. A release pipeline enables you to deliver features for your users efficiently and promptly. AWS CodePipeline, with its powerful integration and automation capabilities of building, testing, and deployment, offers a unique solution to common software delivery issues such as outages during deployment, a lack of standard delivery mechanisms, and challenges faced in creating sustainable pipelines. You’ll begin by developing a Java microservice and using AWS services such as CodeCommit, CodeArtifact, and CodeGuru to manage and review the source code. You’ll then learn to use the AWS CodeBuild service to build code and deploy it to AWS infrastructure and container services using the CodeDeploy service. As you advance, you’ll find out how to provision cloud infrastructure using CloudFormation templates and Terraform. The concluding chapters will show you how to combine all these AWS services to create a reliable and automated CodePipeline for delivering microservices from source code check-in to deployment without any downtime. Finally, you’ll discover how to integrate AWS CodePipeline with third-party services such as Bitbucket, Blazemeter, Snyk, and Jenkins. By the end of this microservices book, you’ll have gained the hands-on skills to build release pipelines for your applications.

Kubernetes objects

You can interact with the Kubernetes cluster to view or change the stage of these objects using the REST API or a command utility such as kubectl to express these objects in yaml format. Kubernetes objects are persistent entities in the Kubernetes system, and Kubernetes use these entities to represent the state of your cluster.

When you create an object in Kubernetes, you tell the Kubernetes system what your desired state of the cluster is, then the Kubernetes system will constantly work to get to the desired state.

Kubernetes objects define what containerized applications are running and on which nodes, what resources are allocated to these applications, and how these applications will behave based on the defined policies such as restart, upgrades, and fault tolerance.

To create the object, you need to call the Kubernetes API server either using the REST API and defining the object specification and desired state in the JSON format or using the kubectl...
