This is a pretty complete and fully-featured end-to-end automation demo with multistage and canary deployments. Done with GCP, GKE/Kubernetes, Terraform, GCB and ArgoCD/Rollouts.

I think this would be interesting for both beginners and people with some experience.

What's in it?

• Multistage deployments (staging, prod)
• Canary deployments
• Horizontal pod/instance autoscaling
• Rollbacks, self-healing
• Distributed tracing, monitoring, logging, profiling, debugging

Setup/deployment is heavily automated so it will be easy for you to deploy it on GCP with Free Trial yourself.

How it works

Complete description/quickstart on GitHub:

As a bonus, in the same README there is a section about implementing something like this in the real world and what you should be looking for while doing it.
