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
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.
