Overview of this book

AWS CodeDeploy, AWS CodeBuild, and CodePipeline are scalable services offered by AWS that automate an application's build and deployment pipeline. In order to deliver tremendous speed and agility, every organization is moving toward automating their entire application pipeline. This book will cover all the AWS services required to automate your deployment to your instances. You'll begin by setting up and using one of the AWS services for automation –CodeCommit. Next, you'll learn how to build a sample Maven and NodeJS application using CodeBuild. After you've built the application, you'll see how to use CodeDeploy to deploy the application in EC2/Auto Scaling. You'll also build a highly scalable and fault tolerant Continuous Integration (CI)/Continuous Deployment (CD) pipeline using some easy-to-follow recipes. Following this, you'll achieve CI/CD for a microservice application and reduce the risk within your software development life cycle globally. You'll also learn to set up an infrastructure using CloudFormation templates and Ansible, and see how to automate AWS resources using AWS Lambda. Finally, you'll learn to automate instances in AWS and automate the deployment lifecycle of applications. By the end of this book, you'll be able to minimize application downtime and implement CI/CD, gaining total control over your software development lifecycle.

In this recipe, we will try to figure out the possible solutions of some common errors:

  1. Access error: Public key denied when connecting to an AWS CodeCommit repository

Problem: The moment you try to access the repository using the SSH Git URL of AWS CodeCommit repository, an error will appear Error: public key denied.

Possible solutions: This error may appear because of no proper set up of the SSH public key. You have to generate the SSH public and private key and upload the public key to the associated IAM user.

Sometimes, we used to upload the public key of the X user and try to access the repository by being the Y user.

  1. Git error: RPC failed; result=56, HTTP code = 200 fatal: The remote end hung up unexpectedly

Problem: When pushing a large change, a large number of changes or a large repository, and long-running HTTPS connections are often...
