- 1. CI CD using AWS Developer Tools Bhuvaneswari Subramani Oct 2019
- 2. Bhuvaneswari Subramani (Bhuvana) Director, Engineering Operations, Infor AWS Community Hero Currently working on Cloud Computing, DevOps &, Performance QA https://installjournal.blogspot.com
- 3. Agenda • AWS CI CD Services Overview • Use case leveraging AWS CI CD Services • Infrastructure Rollouts + WebApp Deployment • buildspec, appspec • Debugging Build & Deployment • Rollback Deployments • Metrics to gauge DevOps
- 4. AWS CI CD Services
- 5. Software Release Phases Source Build Test Deploy Testing • Integration Test • UI Test • Load Test • Penetration Tests Deployment Deployment to Prod Environments Code Management • Check-in source code • Peer review new code • Version Control • Multi-enterprise Package Creation • Compile Code • Run Unit Tests • Create Container Images Continuous Integration Continuous Delivery
- 6. Software Release Phases vs AWS CI CD Services Source Build Test Deploy AWS CodeCommit AWS CodeBuild Third Party Tooling AWS CodeDeploy AWS CodePipeline
- 7. Plight of the self-managed source control repo
- 8. AWS CodeCommit • Secure, Scalable, and managed Git Source control • Use Standard git tools • Scalability, availability and durability of Amazon S3 & Amazon Dynamo DB • No repo size limit • Post commit hooks to call out to SNS / Lambda
- 9. AWS CodeCommit features Visualizer Compare Pull Request
- 11. When there is no CI CD?
- 12. AWS Code Build • Fully managed build service that compiles source code, run tests, and produces software packages • Scales continuously and processes multiple builds • You can provide custom build environments suited to your needs via Docker images • Only pay by the minute for the compute resources you use • Launched with Services like CodePipeline or Jenkins
- 13. AWS CodeBuild Project •Where to get the source code? Which build environment to use? Where to store the artifact? Where to store the build logs?
- 14. AWS CodeDeploy • Automates code deployments to EC2 / On-prem • Handles the complexity of updating your applications • Minimal deployment downtime • Rollback automatically, if failure detected • Supports varied languages and operating systems • Integrates with third-party tools like Jenkins
- 15. AWS CodeDeploy Components Revision 1 Application Revision 2 Revision 3 Revision n Deployment Group Deployments Deploy Config appspec .yml In-place deployment
- 16. AWS CodeDeploy Revision 1 Application Revision 2 Revision 3 Revision n Deployment Group Deployments Deploy Config appspec .yml In-place deployment What to deploy? Where to deploy? How to deploy?
- 17. AWS CodePipeline • Continuous delivery service for fast and reliable application updates • Model and visualize your software release process • Builds, tests and deploys your code on every commit • Integrates with third-party tools
- 18. AWS CodePipeline Action Action Stage Action Action Stage Action Transition
- 19. Quick look @ pricing* • AWS CodeCommit: Anyone with an AWS account can get started with AWS CodeCommit for free. Your account gets 5 active users per month for free (within limits), after which you pay $1 per additional active user per month. • AWS CodeBuild: Only pay by minute for the compute resources you use. • AWS CodeDeploy: There is no additional charge for code deployments to Amazon EC2 instances through AWS CodeDeploy. You pay $0.02 per on- premises instance update using AWS CodeDeploy. • AWS CodePipeline: You pay only for what you use. AWS CodePipeline costs $1 per active pipeline* per month. To encourage experimentation, pipelines are free for the first 30 days after creation. * Pricing as on Sep 2019
- 20. AWS CI CD Workflow
- 21. Use Case • IaC using Cloud Formation Template • Create an EC2 Instance • Install CodeDeploy agent through UserData • Add specific tag `Name = WebApp` • Deploy Web Application • Install Tomcat & deploy WebApp through instructions from appspec.yml
- 24. Infrastructure Rollout + Web App Deployment
- 25. buildspec.yml & appspec.yml files
- 26. buildspec.yml buildspec.yml from Web Application Deployments
- 27. buildspec.yml buildspec.yml from Web Application Deployments Create & store an artifact in S3
- 28. appspec.yml appspec.yml from Web Application Deployments
- 29. appspec.yml Files to be copied to the instance during deployment’s install appspec.yml from Web Application Deployments
- 30. Debugging, Rollback & Metrics
- 31. Debugging Builds • Enable Logging in CloudWatch / S3
- 32. Debugging Builds • Enable Logging in CloudWatch / S3 • Local Build Support for AWS CodeBuild • Get the AWS CodeBuild docker image file from AWS Github • Build the CodeBuild image locally • Setup CodeBuild local Agent • Use the local agent to build your project
- 33. Debugging Deployments • CodeDeploy agent generates agent, updater & deployment logs • Send them to CloudWatch for debugging • CodeDeploy agent logs [EC2/On-prem only] • /var/log/aws/codedeploy-agent/codedeploy-agent.log
- 34. Debugging Deployments • CodeDeploy agent generates agent, updater & deployment logs • Send them to CloudWatch for debugging • CodeDeploy agent logs [EC2/On-prem only] • /var/log/aws/codedeploy-agent/codedeploy-agent.log • CodeDeploy deployment logs • /opt/codedeploy-agent/deployment-root/deployment-logs/ • CodeDeploy updater logs • /tmp/codedeploy-agent.update.log
- 35. Rollback Deployments • Rollback in AWS is actually ====> • Configure re-deploy by enabling • Code deploy -> Rollbacks > • Code deploy -> ‘Automatic Rollbacks’ • Deployment Configuration to enable rollback based on healthy instances
- 36. Metrics to gauge DevOps • Rapid Delivery with Increased Efficiency • Increased Feature releases with reduced TTM • Quicker feedback (system/user) to teams & stake holders • Greater % of defects detected in testing (Unit & SIT Cycles) • Ticket / Incidents volume reduction in PreProd & Prod • High Availability • Elastic & Scalable Infrastructure
