You can use this guide from Bitnami to prepare a Kubernetes cluster in Oracle Cloud: https://docs.bitnami.com/kubernetes/how-to/set-kubernetes-cluster-oracle/

The guide is meant for the Ubuntu image, but just as @sfgroups said, using kubeadm the process should be similar.

You can use kubeadm for the cluster setup. I haven't worked with Oracle Linux. as long as it supports rpm & yam. you can install the kubernets software.

I have established a kubernetes cluster on Oracle Linux 7.4 using Oracle VirtualBox and vagrant.

Github repo can be found https://github.com/bjarteb/ol-kubeadm

You need an oracle account to follow along (it's free)

Oracle® Container Services for use with Kubernetes

vagrant up && vagrant ssh m - and you are ready for k8s!

[vagrant@m ~]$ kubectl get nodes -owide
