Earlier quoted context omitted.
It's still using the same old stack, just containerized. For example, you're no longer manually editing nginx conf, but instead writing the config as yaml annotation to tell the nginx ingress what to do. Instead of editing wp-config.php when deploying wordpress, you specify the db config as environmental variables in yaml file, etc.
Can you explain why one would use Kubernetes? I know containerization but still haven’t figured out wtf Kubernetes is. Everyone and their mother keeps telling me it’s an orchestration tool for containers. It’s as helpful as saying a Pecan pie is an orchestration of flour, sugar and pecans.
The main difference between the different orch. tools is how they pipe the data between Outside and the service cluster. Mesos didn’t help you, you had to build your own service discovery. ECS uses Amazon load balancers and some custom black-box daemons. Kubernetes famously uses a complex mesh of “ingress controllers” and kernel iptables/ipfw spoofing. All take their configurations in some form of JSON or YAML.
