kubernetes-cluster-creator

The script was totally implemented using bash shell, mainly foucus on the offline installation of the kubernetes cluster. As oppose to other tools, it has some main advantage:

• can work in offline environment;
• can automatically shutdown firewall;
• shutdown swap to ensure kubelet working;
• No dependencies, the script was tested on centos minimal installation and ubuntu minimal installation.

The result cluster contains flowing components:

• ETCD 3.3.13
• Flannel 0.11.0
• Docker 18.09.6
• Kubernetes 1.15.3

And in addition, coredns 1.6.2 will be added soon.

Usage

1. Config server ips in the cluster.conf.sh
2. Run ./cluster.install.sh on centos cluster or ./cluster.install.sh --system ubuntu on ubuntu cluster.
