Continuous Delivery to Cloud Foundry: Why your junior devs will love it

How can you take junior developers, hand them the keys to the kingdom, and trust them to deliver features to production for your clients without micromanaging every line of code they push? The answer is easy if you are using tools like Concourse and Cloud Foundry.

Concourse is a tool that allows for automated continuous delivery which also happens to work extremely well with deploying apps to Cloud Foundry.

Speaker Robert Summers recently underwent this journey. He abandoned his career to become a developer through Europe’s leading Web Developer bootcamp and joined Armakuni, a consultancy specialising in cloud-native solutions.

Robert will share some of the challenges that come with entering such a technical field and provide tips for shepherding novices like them into the world of Continuous Delivery and Cloud Foundry.

1. Continuous Delivery to Cloud Foundry Why your Junior Devs will love it!
2. Some Background... ▪ Professional developer since November 2016 ▪ No previous coding experience (past life was in the insurance industry) ▪ Completed an intensive 3 month coding bootcamp ▪ After about 2 weeks of onboarding, moved on a client project and was assigned features to work on
3. Question? How can you take a coding bootcamp grad and get them pushing to master on a client’s app with minimal supervision?
4. Concerns? Senior Dev: Junior Dev: - It takes too long to train new developers to do everything - I don’t know how to do everything… yet - They might break the app - I might break the app
5. Solution Cloud Foundry + Continuous Delivery!
6. Test first mentality
7. Cloud Foundry
8. • Simple to use cli - easy learn Why do we like it?
9. I don’t care how, just run my app $ cf push myapp
10. $ cf scale -i 100 myapp SH!T, it’s a hit - I need more horsepower
11. $ cf create-service... I need a DB and but don’t want to manage it
12. $ cf create-space... I want orgs and spaces so I can safely share a platform
13. Concourse CI Pipeline
14. I want to build Pipelines now! … jobs: - name: job-deploy-myapp plan: - {get: resource-myapp, trigger: true} - put: resource-deploy-myapp params: manifest: myapp/manifest.yml path: myapp
15. Concourse CI Pipeline
16. Continuous Delivery “A software engineering approach in which teams produce software in short cycles, ensuring that the software can be reliably released at any time.” --Wikipedia
17. Cloud Foundry + Concourse = :)
18. Tests - (no external dependencies)
19. Deploy to Pre-production environment
20. End to end tests
21. Deploy to Production Environment
22. Tests on Production
23. What do your Jr Devs Learn from this?
24. Tests are important
25. Environment matters
26. The value of a short feedback loop
27. Why do we love it? ▪ Quick to get started ▪ Feel productive immediately ▪ Rapid learning due to frequent iteration
28. Thanks
