Download KubeKey

KubeKey is a new generation of Kubernetes and KubeSphere installers that help you install Kubernetes and KubeSphere in a simple, fast, and flexible way.

Export KKZONE=cn curl-sfL https://get-kk.kubesphere.io | VERSION=v1.0.1 sh-

Prepare for Mirror

If you want to speed up the installation or your computer room does not have a public network, you can use the private warehouse within the company to push the image to the private warehouse in advance. My warehouse here uses harbor.

Download the offline installation tool, I just use this script to download and push the image

Curl-L-O https://github.com/kubesphere/ks-installer/releases/download/v3.0.0/offline-installation-tool.sh curl-L-O https://github.com/kubesphere/ks-installer/releases/download/v3.0.0/images-list.txt

Pull the image

. / offline-installation-tool.sh-Smurl images-list.txt-d. / kubesphere-images can see the following package # ll total 8606088-rw-r--r-- 1 root root 454465957 Feb 2 15:37 csi-images.tar.gz-rw-r--r-- 1 root root 1231853258 Feb 2 15:33 example-images.tar.gz-rw-r--r-- 1 root root 445244294 Feb 2 14:50 istio-images.tar in the. / kubesphere-images directory .gz-rw-r--r-- 1 root root 762326634 Feb 2 14:27 k8s-images.tar.gz-rw-r--r-- 1 root root 1297767607 Feb 2 14:40 ks-core-images.tar.gz-rw-r--r-- 1 root root 3439146357 Feb 2 15:19 ks-devops-images.tar.gz-rw-r--r-- 1 root root 733165078 Feb 2 14:46 ks-logging-images.tar.gz-rw-r--r-- 1 root root 448651153 Feb 2 15:23 openpitrix-images.tar.gz

Push the image to the private repository and wait for the script to be completed.

Create a multi-node cluster

You can use KubeKey to install both Kubernetes and KubeSphere to create a multi-node cluster by customizing the parameters in the configuration file.

Create a Kubernetes cluster with KubeSphere installed (for example-- with-kubesphere v3.0.0)

. / kk create config-- with-kubernetes v1.17.9-- with-kubesphere v3.0.0

A default config-sample.yaml file is created. You can modify this file according to your environment.
