安装 Docker

[root@localhost~]# yum install docker

启动 docker 服务

[root@localhost~]# systemctl start docker.service
    [root@localhost~]# systemctl enable docker.service

安装 centos 镜像

[root@localhost~]# docker pull centos
    
    Using default tag: latest
    Trying to pull repository docker.io/library/centos ...
    
    latest: Pulling from docker.io/library/centos

    668604fde02e: Pulling fs layer*

检查 centos 镜像安装状态

[root@localhost~]# docker images centos
    
    REPOSITORY          TAG                IMAGE ID            CREATED            SIZE
    
    docker.io/centos    latest              980e0e4c79ec        7 weeks ago         196.7 MB
    
    运行一个新的容器
    [root@localhost~]# docker run -i -t centos /bin/bash
    [root@bd1a482d44f5 /]#
    
    参数解释
    -i, --interactive               Keep STDIN open even if not attached
    
    -t, --tty                            Allocate a pseudo-TTY
    
    PS：“[root@bd1a482d44f5 /]#” 这行出现证明已进入容器

退出容器

[root@localhost~]# exit
    
    exit

查看运行的容器

[root@localhost~]# docker ps
    
    CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
    48a415dde98a        centos              "/bin/bash"         2 hours ago         Up 2 hours                              nauseous_ardinghelli

查看全部容器列表

[root@localhost~]# docker ps -a
    
    CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                     PORTS               NAMES
    bd7d9471fff8        ubuntu              "/bin/bash"         7 minutes ago       Exited (0) 2 minutes ago                       thirsty_stallman
    48a415dde98a        centos              "/bin/bash"         3 hours ago         Up 2 hours                                     nauseous_ardinghelli

启动，停止，重启容器

[root@localhost~]# docker start thirsty_stallman //启动名字为thirsty_stallman的容器
    [root@localhost~]# docker stop thirsty_stallman //停止名字为thirsty_stallman的容器
    [root@localhost~]# docker restart thirsty_stallman //重启名字为thirsty_stallman的容器

重命名容器的名字

`[root@localhost~]# docker rename nauseous_ardinghelli controller`  
/将容器名字为nauseous\_ardinghelli更改成controller

进入与容器的交互模式

[root@localhost~]# docker attach nauseous_ardinghelli
    
    [root@48a415dde98a ~]#
