k8s-kubeone-vagrant

This project provides an example setup for a Kubernetes cluster with KubeOne. The nodes for the cluster can be provisioned with Vagrant.

Prerequisits

This

1. Proper ssh setup for non root user
2. The user requires passwordless sudo permissions

Load Balancer

Perform these steps on node-1:

• Copy Dockerfile to node-1
• Copy haproxy.cfg to node-1

docker build . -t kubeone-haproxy:2.8.4-bullseye
docker run -p 6443:6443 -d --restart always --name haproxy kubeone-haproxy:2.8.4-bullseye

OIDC

Run this commands on node-1:

docker run -p 9090:8080 -d --restart always --name keycloak -e KEYCLOAK_ADMIN=admin -e KEYCLOAK_ADMIN_PASSWORD=admin quay.io/keycloak/keycloak:22.0.5 start-dev

Cluster setup

1. run "kubeone config print --full >> kubeone.yaml"
2. Open kubeone.yaml
   1. set kubernetes version
   2. set cloudProvider to none: {} (none for not supported providers)
   3. set machineController to deploy: false (false for not supported providers)
   4. set values for controlPlane (ssh setup for non root user)
   5. set values for staticWorkers (ssh setup for non root user)
   6. set values for apiEndpoint (loadbalancer IP + port from node-1)
3. run "kubeone apply -m kubeone.yaml"
