Progressive Delivery for Micro-Services Using Argo Rollouts and the Downward API

on YouTube ↗29m

" summary

Shows how to coordinate blue/green and canary across multiple microservices and external resources by combining Argo Rollouts label injection with the Kubernetes Downward API to mount rollout role labels as files. Applications read those files and auto-reload config (Go Viper shown) so DB or queue endpoints switch on promotion. Demo uses RabbitMQ queues, changes only the image tag, achieves zero pod restarts, isolates preview vs production queues, and on promotion the preview instance flips to production queue and continues processing without restarting.
