Kubernetes

You have two basic general flavors. Kubernetes and OKD (used to be OpenShift Origin). OKD uses HAProxy for routes while Kubernetes uses ingress and supports a bunch of different reverse proxy mechanisms including nginx. I think Kubernetes is developed enough over the last couple of years that it is a good option, maybe even better than openshift. Ubuntu Kubernetes is probably the best fit for now over kubeadm and other options.

Getting Started with Calico as network control plane

https://docs.projectcalico.org/v3.8/getting-started/

Install

https://docs.projectcalico.org/v3.7/getting-started/kubernetes/

Note, if you want vxlan and easier in some ways but less scale/security try using flannel

Test it

https://docs.projectcalico.org/v3.7/security/simple-policy

Test simple container

Make sure dns and outbound connections are working

https://kubernetes.io/docs/tasks/administer-cluster/dns-debugging-resolution/

change example to busybox to ubuntu:bionic, debian:buster or whatever and rock an os.
