运行 centos 镜像

[root@sail ~]# docker run -it centos /bin/bash Unable to find image 'centos:latest' locally # 检索本地镜像，发现没有该镜像，则去仓库中搜索。 latest: Pulling from library/centos # 开始从仓库中拉取 a1d0c7532777: Pull complete Digest: sha256:a27fd8080b517143cbbbab9dfb7c8571c40d67d534bbdee55bd6c473f432b177 Status: Downloaded newer image for centos:latest [root@81c83ea42dc0 /]# ls # 由于是以交互方式运行，且进入 /bin/bash 中，此时的路径即为 centos 容器中的 /bin/bash bin dev etc home lib lib64 lost+found media mnt opt proc root run sbin srv sys tmp usr var
由此可以看出，容器就是一个微型的 Linux 系统。它只保留了最核心的功能和最基本的命令，方便进行操作。
