kok

This project is deploy kubernetes control-plane on k8s.

Depend-on

LoadBalancer

Will be used to expose the kube-apiserver service and communicate with apiserver through this IP when adding nodes.

• metallb

StorageClass

Will be used to store individual cluster etcd data and certificate files.

• nfs-subdir-external-provisioner

  kubectl patch storageclass nfs-client -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'

Quick start

You need a kubernetes cluster first, then deploy this project on this kubernetes.

sudo modprobe nfs 
sudo modprobe nfsd
docker run --privileged -d --name nfs-server \
--net host \
-e NFS_EXPORT_0='/aaa *(rw,fsid=1,sync,insecure,no_subtree_check,no_root_squash)'  \
-v /Users/peng.liu/temp/nfs:/aaa \
erichough/nfs-server:2.2.1

kind create cluster --name kok --image docker.m.moby.org.cn/kindest/node:v1.30.2
sudo bin/cloud-provider-kind

helm upgrade -i kok ./kok -n kok --create-namespace

# get EXTERNAL-IP and redeploy
helm upgrade -i kok ./kok -n kok --create-namespace \
--set webhookUrl=http://<EXTERNAL-IP>:8080 

Now you can open the link to create the cluster

• http://<EXTERNAL-IP>:8080/console/cluster
