如何使用kubekey安裝kubesphere

這篇文章主要為大家展示了“如何使用kubekey安裝kubesphere”，內(nèi)容簡而易懂，條理清晰，希望能夠幫助大家解決疑惑，下面讓小編帶領(lǐng)大家一起研究并學(xué)習(xí)一下“如何使用kubekey安裝kubesphere”這篇文章吧。

 下載 KubeKey

KubeKey 是新一代 Kubernetes 和 KubeSphere 安裝器，可幫助您以簡單、快速、靈活的方式安裝 Kubernetes 和  KubeSphere。

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

準(zhǔn)備鏡像

如果您想讓安裝加快或者您的機(jī)房沒有外網(wǎng)，可以使用公司內(nèi)部的私有倉庫，預(yù)先把鏡像推送到私有倉庫中，我這里的倉庫使用harbor

下載離線安裝工具，我這里只是用這個(gè)腳本來下載和推送鏡像

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

拉取鏡像

./offline-installation-tool.sh -s -l images-list.txt -d ./kubesphere-images 在./kubesphere-images目錄下能看到以下壓縮包 # 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.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

推送鏡像到私有倉庫，待腳本完成即可

./offline-installation-tool.sh -l images-list.txt -d ./kubesphere-images -r hub.evbj.easou.com

創(chuàng)建多節(jié)點(diǎn)集群

您可用使用 KubeKey 同時(shí)安裝 Kubernetes 和 KubeSphere，通過自定義配置文件中的參數(shù)創(chuàng)建多節(jié)點(diǎn)集群。

創(chuàng)建安裝有 KubeSphere 的 Kubernetes 集群(例如 --with-kubesphere v3.0.0)

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

系統(tǒng)將創(chuàng)建默認(rèn)的 config-sample.yaml 文件。您可以根據(jù)您的環(huán)境修改此文件。
