This lab walks you through how to perform ECS to CodeDeploy deployment using ECR as a source and CodePipeline as Pipeline with the help of ECS. In other words, you will learn to deploy container applications using blue-green deployment.
Duration: 120 minutes
AWS Region: US East (N. Virginia) us-east-1
AWS CodePipeline helps you in modeling, visualizing, and automating the steps required to continuously deliver the release of your software.
Using AWS CodePipeline, you can create and configure various stages of a software release process. It helps you automate the delivery of software having a frequent release.
AWS CodePipeline can help you do various tasks, such as
Automating release process of software delivery
View Pipeline history details
Customize the stages and action
Choose the source, build and deploy stage.
Add the manual approval for the release process.
Integration with various AWS Services.
AWS CodePipeline at a glance.
Source: A place where source code with its revisions is stored. It can be Amazon S3 Bucket, CodeCommit repository, or Git-based repositories such as GitHub and Bitbucket.
Build: In this phase, the buildspec.yml file plays a very important role. This is the phase where software is tested and build.
Staging: A place where code is deployed into a testing environment or also called a pre-production environment. You use this phase to test the software before making it live for public users. This is an optional stage if the application is well tested before uploading to the source.
Manual approval: This phase helps software engineers to get the approval for the code, deployed and well tested into the testing environment. It uses SNS to get the approvals on the email. This is the optional stage.
Deploy: The last phase for the delivery of software. Using AWS CodePipeline, applications can be deployed on Amazon EC2 Instances using CodeDeploy, Elastic Beanstalk, or AWS OpsWorks Stacks.
