Docker----Docker发布镜像到DockerHub

（1）在​​dockerhub​​网站注册一个账号，如账号为redrose2100

（2）编写DockerFile文件，如下：

FROM centosMAINTAINER redrose2100ENV JAVA_HOME /usr/local/jdk_1.8/WORKDIR /usr/localRUN yum install -y vimRUN yum install -y net-toolsEXPOSE 80CMD echo $JAVA_HOMECMD echo "---end---"CMD /bin/bash

（3）在本地制作一个镜像

docker build -f Dockerfile -t mycentos:0.0.1 .

查看制作好的镜像如下

[root@iZbp1flzt6x7pxmxfhmxeeZ opt]# docker imagesREPOSITORY TAG IMAGE ID CREATED SIZEmycentos 0.0.1 71f621e7c514 6 seconds ago 337MBnginx latest f8f4ffc8092c 4 weeks ago 133MBmysql 5.7 9f35042c6a98 4 weeks ago 448MBcentos latest 5d0da3dc9764 6 weeks ago 231MB[root@iZbp1flzt6x7pxmxfhmxeeZ opt]#

（4）修改tag标签

docker tag mycentos:0.0.1 redrose2100/mycentos:0.0.1

修改后查看镜像如下：

[root@iZbp1flzt6x7pxmxfhmxeeZ opt]# docker imagesREPOSITORY TAG IMAGE ID CREATED SIZEmycentos 0.0.1 71f621e7c514 About a minute ago 337MBredrose2100/mycentos 0.0.1 71f621e7c514 About a minute ago 337MBnginx latest f8f4ffc8092c 4 weeks ago 133MBmysql 5.7 9f35042c6a98 4 weeks ago 448MBcentos latest 5d0da3dc9764 6 weeks ago 231MB[root@iZbp1flzt6x7pxmxfhmxeeZ opt]#
