製作centos7-ssh映象配置Dockerfile映象構建檔案

docker run -it   centos   /bin/bash

exit        #退出centos docker容器

docker tag 980e0e4c79ec   192.168.161.117:5000/os/centos_sshd         #儲存安裝了sshd的映象庫為centos_sshd

docker push 192.168.161.117:5000/os/centos_sshd                                     #提交到本地映象庫

構建dockerfile

mkdir tomct-centos

上傳apache-tomcat-8.5.9.tar.gz  demo_web.war    jdk1.8.0_45 檔案

vi Dockerfile

#新生成的映象是基於sshd-centos映象
