Kubecon: Continuously Delivering Microservices in Kubernetes

Transcript

1. Continuous Delivery in Kubernetes Sandeep Parikh @crcsmnky Solutions Architect Google

   Cloud Platform

2. Why Is This Important Bulletproof process to go from code

   to production Centralized, repeatable building/tagging/pushing Iterate quickly and reliably Hands off my kubectl

3. Continuous Integration Test Code Commit Push Test Build The ideal

   development flow

4. Continuous Integration Test Code Commit Push Test Build The ideal

   development flow Test D’oh! Code Commit Push Test Crap! Build Whoops! The real development flow

5. Continuous Delivery Test Build Deploy Testing Staging

6. Continuous Deployment Deploy Approve Deliver Profit

7. Why Continuous? Fail fast I broke the build! Blame fast

   Who broke the build? Deliver faster Better software in customers hands!

8. Tools

9. Jenkins

10. Kubernetes Cluster (GKE) Kubernetes Cluster Node 1 Node 3 Node

    2

11. Kubernetes Cluster (GKE) Jenkins Leader Node 1 Node 3 Node

    2 Jenkins Leader

12. Kubernetes Cluster (GKE) Jenkins Service Node 1 Node 3 Node

    2 Jenkins Leader Jenkins Service

13. Kubernetes Cluster (GKE) Jenkins Builder Node 1 Node 3 Node

    2 Jenkins Leader Jenkins Builder Jenkins Builder Jenkins Builder Jenkins Builder Jenkins Service Jenkins Builder

14. Kubernetes Cluster (GKE) Jenkins Proxy Node 1 Node 3 Node

    2 Jenkins Leader Jenkins Builder Jenkins Builder Jenkins Builder Jenkins Builder Jenkins Service Jenkins Builder nginx

15. Kubernetes Cluster (GKE) Jenkins Proxy Service Node 1 Node 3

    Node 2 Jenkins Leader Jenkins Builder Jenkins Builder Jenkins Builder Jenkins Builder Jenkins Service Jenkins Builder nginx nginx Service

16. Microservices

17. None

18. Kubernetes Cluster (GKE) Microservices Node 2 Node 1 Backend Frontend

    Frontend Backend Service Frontend Frontend Service Backend Backend

19. Microservices & Namespaces Virtual clusters backed by the same physical

    cluster Divide cluster resources by different use cases Supports quotas for managing resources Test, Staging, Production, etc.

20. Pods Time Microservices & Rolling Update Replace Replication Controller A

    with Replication Controller B by updating one Pod at a time. A B A B A B A B A B A B

21. Workflow

22. Kubernetes Workflow Create Push Package Expose

23. Mapping To Jenkins Workflow plugin, Freestyle doesn’t fit Define a

    flexible, extensible, script-based CD pipeline Groovy for scripting actions Supports human input/approval

24. Workflow Repo Kubernetes Cluster (GKE) Github Jenkins µservice µservice Default

    Staging Production

25. Workflow Repo Kubernetes Cluster (GKE) Github Jenkins µservice µservice Default

    Staging Production 1 Push 1

26. Workflow Repo Kubernetes Cluster (GKE) Github Jenkins µservice µservice Default

    Staging Production 1 2 Push Build 1 2

27. Workflow Repo Kubernetes Cluster (GKE) Github Jenkins µservice µservice Default

    Staging Production 1 2 3 Push Build Clone 1 2 3

28. Workflow Repo Kubernetes Cluster (GKE) Github Jenkins µservice µservice Default

    Staging Production 1 2 3 4 Push Build Clone Stage 1 2 3 4

29. Workflow Repo Kubernetes Cluster (GKE) Github Jenkins µservice µservice Default

    Staging Production 1 2 3 5 4 Push Build Clone Stage Approve 1 2 3 4 5

30. Workflow Repo Kubernetes Cluster (GKE) Github Jenkins µservice µservice Default

    Staging Production 1 2 3 5 4 Push Build Clone Stage Approve Deploy 1 2 3 4 5 6 6

31. Demo Come find me after the talk and I promise

    I’ll run it live :)

32. Shout Out Give Evan Brown (@evanbrown) a high-five next time

    you see him. He’s super smart and got this whole thing working.
