About

Kubekit is a deployment toolkit, it provides offline installation solution for kubernetes. You can use it for deploying Kubernetes to OFFLINE production environment.

The Kubekit will install

• Docker (1.12.6)
• Kubernetes and all its components
• Kubernetes dashboard, with default node port:31234

Highlights

• Easy to bring up Kubernetes master by only one CLI command
• Ease of use through Web UI portal
• Manage and initialize multiple nodes with "one-click"

Supported OS

• CentOS release 7.3.1611 with minimal installation (Already tested & verified)
• CentOS release 7.4.1708 with minimal installation (Already tested & verified)

Requirements

• Make sure you have root privileges for all the servers.
• The firewalls are not managed, you'll need to implement your own rules the way you used to, in order to avoid any issue during deployment you should disable your firewall.
• Make sure all the kubernetes nodes have different hostnames.
• Make sure the date and timezone of all the kubernetes nodes are the same.

Quick Start

1. Download latest release of kubekit:

• Download it form our mirror server:[Download] (RECOMMENDED!)

• Or download it from GitHub

  Then extract it to ./kubekit/

1. Download offline package according to your OS version:

1. Extract all the files from offline package to ./kubekit/package and make *.sh executable:

cd package
chmod +x *.sh

1. COPY ./kubekit to a node which is selected to be Kubernetes master.

2. Login to that node, initialize it with Kubernetes master by its IP:

   ./kubekit init 192.168.0.100
   

3. Take a cup of coffee and wait until master node is ready. And also, a Web UI portal will be available with default port: 9000.

4. Access the Web UI Portal with http://MASTER_IP:9000 and initialize other Kubernetes worker nodes through it.

5. Don't forget to reload bash settings before using kubectl: source ~/.bashrc
