使用xserver1虛擬機，使用VMWare軟件自行添加一塊大小為20G的硬盤，使用fdisk命令對該硬盤進形分區(qū)，要求分出兩個大小為5G的分區(qū)。使用兩個分區(qū)，創(chuàng)建名xcloudvg的卷組，然后再創(chuàng)建一個5G的分區(qū)，將xcloudvg擴容至15G，最后執(zhí)行vgdisplay命令查看卷組信息。將上述所有操作命令和返回結果以文本形式提交到答題框。

Docker安裝
使用xserver1節(jié)點，自行配置YUM源，安裝docker服務（需要用到的包為xserver1節(jié)點/root目錄下的Docker.tar.gz）。安裝完服務后，將registry_latest.tar上傳到xserver1節(jié)點中并配置為私有倉庫。要求啟動registry容器時，將內(nèi)部保存文件的目錄映射到外部的/opt/registry目錄，將內(nèi)部的5000端口映射到外部5000端口。依次將啟動registry容器的命令及返回結果、執(zhí)行docker?info命令的返回結果以文本形式提交到答題框。?

Dockerfile編寫
使用xserver1節(jié)點，新建目錄centos-jdk，將提供的jdk-8u141-linux-x64.tar.gz復制新建的目錄，然后編輯Dockerfile文件，文件要求如下：?
1.使用centos:latest基礎鏡像；?
2.指定作為為xiandian；?
3.新建文件夾/usr/local/java用于存放jdk文件；?
4.將JDK文件復制到鏡像內(nèi)創(chuàng)建的目錄并自動解壓；?
5.創(chuàng)建軟連接：ln?-s?/usr/local/java/jdk1.8.0_141?/usr/local/java/jdk；?
6.設置環(huán)境變量如下?
ENV?JAVA_HOME?/usr/local/java/jdk?
ENV?JRE_HOME?${JAVA_HOME}/jre?
ENV?CLASSPATH?.:${JAVA_HOME}/lib:${JRE_HOME}/lib?
ENV?PATH?${JAVA_HOME}/bin:$PATH
?編寫完畢后，構建名為centos-jdk的鏡像，構建成功后，查看鏡像列表。最后將Dockerfile的內(nèi)容、構建鏡像的操作命令、查看鏡像列表的命令和返回的結果以文本形式提交到答題框。

部署K8S集群
使用xserver1、xserver2節(jié)點，自行配置好網(wǎng)絡，安裝好docker-ce。部署K8S?集群，不要求部署kubernetes-dashboard。部署K8S平臺完成后，在主節(jié)點使用命令依次檢查集群狀態(tài)、Pods狀態(tài)、各節(jié)點的狀態(tài)。最后將檢查狀態(tài)的命令及返回結果以文本形式提交到答題框。?
