KubeSphere Container Platform

Follow these instructions to prepare the KubeSphere Container Platform for Istio. You can download KubeSphere to easily install a Kubernetes cluster on your Linux machines.

KubeSphere provides All-in-One and Multi-Node installations. This enables quick setup and manages Kubernetes and Istio in a unified web console. This tutorial will walk you through the All-in-One installation. Reference Multi-node Installation for further information.

Prerequisites

A Linux machine that is either a virtual machine or bare metal. This machine requires at a minimum:

  • Hardware:

    • CPU: at least 2 Cores
    • Memory: at least 4 GB

  • Operating Systems:

    • CentOS 7.4 ~ 7.7 (64-bit)
    • Ubuntu 16.04/18.04 LTS (64-bit)
    • RHEL 7.4 (64-bit)
    • Debian Stretch 9.5 (64-bit)

Ensure your firewall meets the port requirements. If this is not immediately feasible, you may evaluate Istio and KubeSphere by disabling the firewall as documented in your distribution.

Provisioning a Kubernetes cluster

  1. Download KubeSphere to your Linux machine, move to the KubeSphere directory. For example, if the created directory is kubesphere-all-v2.1.1:

    1. $ curl -L https://kubesphere.io/download/stable/latest > installer.tar.gz
    2. $ tar -xzf installer.tar.gz
    3. $ cd kubesphere-all-v2.1.1/scripts

  2. Execute the installation script, it will create a standard Kubernetes cluster. Select the “1) All-in-one” option when prompted:

    1. $ ./install.sh

  3. Installation may take 15 ~ 20 minutes. Wait until all pods are running. Access the console using the account information obtained from the installation logs:

    1. #####################################################
    2. ###              Welcome to KubeSphere!           ###
    3. #####################################################
    4. Console: http://192.168.0.8:30880
    5. Account: admin
    6. Password: It will be generated by KubeSphere Installer

    At the same time, Kubernetes has been installed into your environment.
