Atagg2015 Continuous delivery by building environment using docker
1 like•237 views
The document discusses how PayUMoney uses Docker containers to enable continuous delivery. It outlines challenges with limited testing environments and long setup times. PayUMoney developed a standardized Docker setup to allow anyone on the team to quickly spin up production-like environments on their own laptops. This enabled automated testing of all code branches, fast merging to mainline, and continuous deployment to production with zero downtime releases. Speakers Nitin Mukhija and Tarun Lalwani from PayUMoney presented on how Docker simplified their environment management and improved their delivery process.

- 4. Release Strategy - Challenge • Want Zero downtime Releases – During Release i.e. code deployment – Throughout – well tested code on Live • Fast delivery of High Quality Product Confidential | Copyright © Agile Testing Alliance Global Gathering • What we are doing everyday... – Serving 800K transactions requests – 4-5 Production Releases – With...Zero Downtime
- 5. How we do it? • Established Rigorous Agile cycle involving PM DevDeployment Confidential | Copyright © Agile Testing Alliance Global Gathering to trap defects in the early stages of SDLC Test
- 6. Let’s see how... Confidential | Copyright © Agile Testing Alliance Global Gathering
- 7. Release Strategy • We cater to fast changing requirements – coming from multiple sources – no formal sprints • Requirements Review – Feature team meetings to stay synchronized Confidential | Copyright © Agile Testing Alliance Global Gathering – Feature team meetings to stay synchronized • Acceptance Test Cases – Preparation – Review by PM & Dev • Development & Testing – Modelled for Continuous Delivery

- 10. Development & Testing • Area Owners – Modular Development – reduces bugs • Code branches - Catch the train model – non- blocking releases Confidential | Copyright © Agile Testing Alliance Global Gathering blocking releases

- 12. Development & Testing • Area Owners – Modular Development – reduces bugs • Code branches - Catch the train model – non- blocking releases Confidential | Copyright © Agile Testing Alliance Global Gathering blocking releases • Mandatory Code Reviews • Only Test team can push code to Prod • Dev-Test pair close collaboration – catch bugs early
- 13. Challenge in Testing Dev Code branch • Team of 70 developers and testers – Limited number of environments – A server with 8 GB RAM and 4 core CPU can host only 2 environments – Time wasted in waiting for environment to be Confidential | Copyright © Agile Testing Alliance Global Gathering – Time wasted in waiting for environment to be available – Test environments NOT mock production – Not possible to run automation on just any environment – Difficult to maintain growing number environments – Manual process to create new test environment – 2 days
- 14. What we required • Ability for anyone in team to create new test env anytime on the fly • Scalable model – to take care of complexity • Easy to use and maintain Confidential | Copyright © Agile Testing Alliance Global Gathering • Easy to use and maintain • Customizable deployments
- 15. Lets see how we did that… Confidential | Copyright © Agile Testing Alliance Global Gathering

Life made easy - Continuous Delivery • Create standard Production like environment in minutes – Every team member has their own test environment – Dev code branches automatically synched with Confidential | Copyright © Agile Testing Alliance Global Gathering – Dev code branches automatically synched with mainline and deployed – CI – Automation is kicked off automatically – Once tester signs off, code is merged to mainline – Release the code changes in mainline to Production - ANYTIME – Achieving Continuous Delivery
