    0d320f497f02db0577174b95926659bcd6ccb6d58ed7ae8d96439465012f4742
    $ docker ps -a
    CONTAINER ID   IMAGE       COMMAND                  CREATED          STATUS          PORTS                 NAMES
    0d320f497f02   centos      "bash"                   10 seconds ago   Created                               sleepy_babbage
    
  6. 查看容器
    # 查看当前正在运行的容器
    $ docker ps
    CONTAINER ID   IMAGE       COMMAND                  CREATED          STATUS          PORTS                 NAMES
    e3266aa82bfa   mysql:5.7   "docker-entrypoint.s…"   10 minutes ago   Up 10 minutes   3306/tcp, 33060/tcp   charming_euler
    
    # 查看所有容器
    $ docker ps -a
    CONTAINER ID   IMAGE       COMMAND                  CREATED          STATUS          PORTS                 NAMES
    e3266aa82bfa   mysql:5.7   "docker-entrypoint.s…"   10 minutes ago   Up 10 minutes   3306/tcp, 33060/tcp   charming_euler
    
  7. 启动容器
    # 通过id或名称来操作
    $ docker start 0d320f497f02
    0d320f497f02
    
  8. 进入容器(exec与attach的区别)

  • exec是执行命令的意思,就是在当前宿主机上执行容器中的命令,通过-it的参数可以输入与输出,执行bash命令就是其中的一种,这个命令会打开一个终端,此时宿主主机当前的终端被容器内的终端所覆盖,所以的操作都会被容器接管
  • attach:Attach local standard input, output, and error streams to a running container,意思是跟踪容器内的输入与输出,也就是说,如果多个终端同时attach到一个容器,大家的可以看到相同的界面,我能看到你输入的,你也能看到我输出的,同步。

    # 通过Docker执行脚本的方式打开容器内的终端
    $ docker exec -it 582eb515c4ee bash
    [root@582eb515c4ee /]# 
    
    # 通过attach命令进入容器的控制台
    $ docker attach 582eb515c4ee
    [root@582eb515c4ee /]# 
    
  1. 退出容器: Ctrl + P + Q 注意顺序不能乱

  2. 停止容器

    # 通过id或名称来操作
    $ docker stop sleepy_babbage 
    sleepy_babbage
    
  3. 删除容器
     # 删除容器通过id或名称来删除
     $ docker rm 0d320f497f02
     0d320f497f02
    
  4. 端口映射
     # 宿主主机的1080端口映射到容器中主机的80端口
     $ docker run -d -p 1080:80 nginx
     eace3d16b4f19e5d555bddc90c57a5b261196c62f1482513cfabc5b6ec7d4cce
    
     # 查看创建好的容器
     $ docker ps
     CONTAINER ID   IMAGE       COMMAND                  CREATED          STATUS          PORTS                  NAMES
     eace3d16b4f1   nginx       "/docker-entrypoint.…"   3 seconds ago    Up 1 second     0.0.0.0:1080->80/tcp   gallant_maxwell
    
  5. 卷宗映射
    # 将宿主机中/root/data 目录挂载到 容器中/data目录
    $ docker create -it -v /root/docker:/data centos bash
    a0c4b4f3bcc256193c49e86b88a1eb239051c955a5e6af031e821d7d3644d755
    
    #查看挂载详情
    $ docker inspect a0c4b4f3bcc2
    "Mounts": [
        {
            "Type": "bind",
            "Source": "/root/docker",
            "Destination": "/data",
            "Mode": "",
            "RW": true,
            "Propagation": "rprivate"
        }
    ],
