Codefresh is a Kubernetes-native CI/CD product used by 20,000 users globally. The document discusses using Codefresh to build a CI/CD pipeline across multiple Kubernetes clusters in different clouds or regions. This provides high availability and allows mitigating outages by failing over workloads between clusters. It also demonstrates using Istio for a canary deployment process, deploying a new version to a percentage of traffic initially and then routing all traffic to it if everything works as expected.

15. Demo

16. Canary ● Deploy a new version of your
app
● Give a percentage of traffic
the new version
● If it works, give it 100%
Prod Version Canary Version

17. Canary
Start with the prod version of your app.
Prod Version All users get prod

18. Canary
Deploy a Canary version.
Prod Version All users get prod Canary Version

19. Canary
Mix traffic
Prod Version A portion of users
receive canary
Canary Version

20. Canary
Monitor canary, if everything looks good, send more traffic
Prod Version A portion of users
receive canary
Canary Version

21. Canary
Complete rollout, now the canary version, becomes the prod version
Prod Version Send all traffic to
canary version
Canary Version

22. Canary
We can remove the old version, or keep it for a hot swap
Send all traffic to
canary version
