Docker常用命令

2018-01-19 20:33 441 查看
查看镜像

docker images


查看正在运行的容器

docker ps


查看所有的容器

docker ps -a


启动某个容器

docker start  containerID||containerName


进入某个容器

docker attach containerID||containerName  //第一种方法

----------

E:\cmder
λ docker exec -it containerID||containerName bash   //第二种方法：exec需要至少两种参数；-it参数一起使用出现linux命令提示符;
root@fce7cbf56eff:/#


exec进入容器后exit不会使容器停止，attach进入容器之后，exit会停止容器。attach与exec对比如下：

E:\cmder
λ docker ps
