创建镜像
基于container创建镜像
首先基于镜像创建一个容器，并在容器添加新文件
# docker run --hostname web --name web-container -it centos:version7 /bin/bash [root@web /]# cd /usr/local/ [root@web local]# mkdir www [root@web local]# cd www/ [root@web www]# cp -r /etc/* . # docker ps -a CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 6eb1f9a40fab centos:version7 "/bin/bash" 44 seconds ago Up 43 seconds web-container
可以看到当前有一个正在运行的容器web-container，并已经写入新数据，现在将基于该容器创建一个新的镜像文件
# docker commit --author "Crist Lee(crist.lee@tnave.com)" --message "Add new web files." web-container centos:web sha256:abfc8b292519afd833a8ec816dc64d1b8fa1067241e680efdf7fe563276d5d79 # docker images REPOSITORY TAG IMAGE ID CREATED SIZE centos web abfc8b292519 5 seconds ago 221MB centos version7 0f3e07c0138f 2 weeks ago 220MB
基于dockfile创建镜像

利用镜像创建容器
docker run --hostname=mysql -name=mysql -it cenots/centos7-mysql57 /bin/bash 24b2ccd981f4 # docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 24b2ccd981f4 cenots/centos7-mysql57 "/bin/bash" 3 hours ago Up 3 hours 3306/tcp mysql
此时进入容器默认以mysqladmin进入，如需要以root进入，执行
# docker exec -it -u root mysql /bin/bash
