Running a Kubernetes cluster with RKE in minutes

This article is a short instruction on how to build your own k8s cluster with a VPS-provider and RKE. I’m going to use Scaleway as a VPS-provider.

Prerequisites

• install rke cli locally
• provision a new VPS instance, I used DEV1-M with Ubuntu Bionic

Steps

• Install the RKE-compatible docker with the following command

curl https://releases.rancher.com/install-docker/19.03.sh | sh

• Add your user to docker group

usermod -aG docker root

• Set AllowTcpForwarding yes in

vi /etc/ssh/sshd_config

• Restart sshd service

systemctl restart sshd.service

• Use rke config to generate cluster configuration, make sure you set etcd and controlplane to [y] when asked about roles
• Run

rke up

• Copy cluster config to your local ~/.kube/config

cp kube_config_cluster.yml ~/.kube/config

• Check your nodes status

kubectl get nodes -o wide
