################## Rancher v2.1.7 + Kubernetes 1.13.4 ################
####################### 以下為聲明 #####################
此文檔是在兩台機上進行的實踐,kubernetes處於不斷開發階段
不能保證每個步驟都能准確到同步開發進度,所以如果安裝部署過程中有問題請盡量google
按照下面步驟能得到什么?
1.兩台主機之一會作為Rancher的server,另外一台作為Rancher Server的node節點添加進Rancher Server,得到安裝好的Rancher,並以Rancher UI進行呈現
2.作為node節點的主機會被安裝kubernetes,並以kubernetes dashboard的方式呈現
3.將建立一個登陸賬號登陸kubernetes dashboard 並解決kubernetes dashboard token超時的問題
4.部署測試pod 和 container,(以nginx為例)
5,認識Rancher和kubernetes,知道其長什么樣子能做什么工作。
6.此文不做生產環境使用,如果使用到生產環境,責任自負。只作為學習Rancher和kubernetes使用,由於時間關系,文中有錯誤的地方歡迎指正交流。
7.此文分為三部分:
CentOS7安裝Rancher2.0並部署kubernetes (一)---部署Rancher
CentOS7安裝Rancher2.0並部署kubernetes (二)---部署kubernetes
CentOS7安裝Rancher2.0並部署kubernetes (三)---解決登錄kubernets超時和部署測試Pod和Containter[nginx為例]
