k8s用戶界面k8s-manager的本質(zhì)及如何進(jìn)行部署

發(fā)布時(shí)間：2021-10-12 09:27:50 來源：億速云 閱讀：199 作者：柒染 欄目：云計(jì)算

k8s用戶界面k8s-manager的本質(zhì)及如何進(jìn)行部署，相信很多沒有經(jīng)驗(yàn)的人對此束手無策，為此本文總結(jié)了問題出現(xiàn)的原因和解決方法，通過這篇文章希望你能解決這個(gè)問題。

k8s用戶界面——k8s-manager

1、k8s-manager簡介：

①、k8s-manager是一個(gè)基于瀏覽器的接口Kubernetes API，功能同kubectl。

②、當(dāng)前版本和官方的kube-dashboard，但不是一個(gè)等級

③、k8s-manager鏡像有200M左右，有點(diǎn)大，登陸進(jìn)去，運(yùn)行的是nginx服務(wù)，nginx配置文件：/etc/nginx/sites-enabled/default，主目錄：/var/www

④、web界面只能查看namespace、events、nodes等簡單信息

⑤、Resource Quotas功能，未開通，期待

⑥、僅供學(xué)習(xí)擴(kuò)展

2、部署：

①、下載鏡像：

docker pull mlamina/k8s-manager:latest

    看下載過程，發(fā)現(xiàn)這個(gè)鏡像在build的時(shí)候，有很多RUN

[root@localhost kube-1.2]# docker pull mlamina/k8s-manager:latest

Status: Downloaded newer image for docker.io/mlamina/k8s-manager:latest

②、創(chuàng)建Namespace：

#創(chuàng)建namespace

[1065][root@www : kube-1.2]# cat kube-system.json

{

  "kind": "Namespace",

  "apiVersion": "v1",

  "metadata": {

    "name": "kube-system"

  }

}

[1066][root@www : kube-1.2]#

[1066][root@www : kube-1.2]# kubectl create -f kube-system.json

namespace "kube-system" created

[1067][root@www : kube-1.2]#

③、創(chuàng)建k8s-manager副本及pod：

[1069][root@www: kube-1.2]# cat k8s-manager-rc.yml

apiVersion: v1

kind: ReplicationController

metadata:

  name: k8s-manager

  namespace: kube-system

④、創(chuàng)建service：
