I'm learning Kubernetes and want to test out the auto scaling, and I think there isn't anything other than a CMS can represent the majority websites today. I spend several days searching on Google. Though it comes some positive results, none of them are open sourced (at least self-hostable).
I know WordPress can be scaled out to serve millions, but the setup is way too complicated.
Things I look for:
- Native Scaling
- Small docker container size
- Decent plugin system for things like OpenID
Things I don't really care:
- Storage system (Flat file/Database)
I will be surprised that if there isn't a FOSS CMS build with these functionalities as micro-services with Kubernetes/EKS are the norm today.
