4.给镜像打标签
[root@ansiblemanaged02 src]# docker tag centos:latest centos1[root@ansiblemanaged02 src]# docker tag centos:latest centos1:0.1[root@ansiblemanaged02 src]# docker imagesREPOSITORY TAG IMAGE ID CREATED SIZE centos latest 5182e96772bf 5 weeks ago 200MB centos1 0.1 5182e96772bf 5 weeks ago 200MB centos1 latest 5182e96772bf 5 weeks ago 200MB
5.把镜像做为容器启动
// 把镜像启动为容器，-i表示让容器的标准输入打开，-t表示分配一个伪终端，// -d表示后台启动，要把-i -t -d 放到镜像名字前面[root@ansiblemanaged02 src]# docker run -itd centos1cb1b747c37a9c6c6f7bf152943330ea3adced83aa6fbac914e3279b72d5b732// 查看运行的容器，加上-a选项后可以查看所有容器，包括未运行的[root@ansiblemanaged02 src]# docker ps -aCONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES1cb1b747c37a centos "/bin/bash" 39 seconds ago Up 36 seconds happy_euler
6.删除镜像
// 删除指定镜像， 其中后面的参数可以是tag，如果是tag时，实际上是删除该tag。// 当后面的参数为镜像ID时，则会彻底删除整个镜像，所有标签也会一同删除[root@ansiblemanaged02 src]# docker imagesREPOSITORY TAG IMAGE ID CREATED SIZE centos1 0.1 5182e96772bf 5 weeks ago 200MB centos1 latest 5182e96772bf 5 weeks ago 200MB centos latest 5182e96772bf 5 weeks ago 200MB [root@ansiblemanaged02 src]# docker rmi centos1:0.1Untagged: centos1:0.1[root@ansiblemanaged02 src]# docker images REPOSITORY TAG IMAGE ID CREATED SIZE centos1 latest 5182e96772bf 5 weeks ago 200MB centos latest 5182e96772bf 5 weeks ago 200MB [root@ansiblemanaged02 src]# docker rmi centos1:latestUntagged: centos1:latest [root@ansiblemanaged02 src]# docker imagesREPOSITORY TAG IMAGE ID CREATED SIZE centos latest 5182e96772bf 5 weeks ago 200MB
