Prepare the dispatch server

1. Downlaod installer from 百度网盘: URL: https://pan.baidu.com/s/1mikM3Ao Code: bvj5
2. Copy it to the production server
3. Go to the installer directory, host it with a simple HTTP server by Python:

[root@master k8s-deploy-1.5]# python -m SimpleHTTPServer
Serving HTTP on 0.0.0.0 port 8000 ...

Install K8S master

1. Get the IP address of dispatch server, for example: 192.168.0.10

2. Install K8S master via curl:

   curl -L http://192.168.0.10:8000/install.sh | bash -s master

3. When you see that "K8S master install finished!" remember the token output like this: " kubeadm join --token f8c407.9aa4bb840dfe2da0 192.168.0.10"

Install K8S node

To initialize a node & join the K8S cluster is simple:

curl -L http://192.168.0.10:8000/install.sh |  bash -s join --token=f8c407.9aa4bb840dfe2da0 192.168.0.10

Repeat this step if you want to setup multiple K8S nodes.
