11、容器剥离当前终端的方法

### ctrl+p 然后在 ctrl+q 可使容易剥离当前终端 ###
[root@Tang ~]# docker container run --name mycentos1 -it myap:v2 /bin/bash
[root@afb9f9ee6cbe /]# ifconfig | grep inet -A 1
        inet 172.17.0.4  netmask 255.255.0.0  broadcast 172.17.255.255
        ether 02:42:ac:11:00:04  txqueuelen 0  (Ethernet)
--
        inet 127.0.0.1  netmask 255.0.0.0
        loop  txqueuelen 1000  (Local Loopback)
[root@afb9f9ee6cbe /]# [root@Tang ~]#   

### 容器剥离当前终端 ###
[root@Tang ~]# 

12、容器内的第一个进程必须一直处于运行的状态，否则容器就会处于退出状态

12.1 运行一个容器，可以看出 /bin/bash 是 PID 为 1 的进程

[root@Tang ~]# docker container run --name mycentos -it myap:v2 /bin/bash
[root@57bd8a923604 /]# ps -aux
USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
root         1  1.0  0.0  11828  1880 pts/0    Ss   07:16   0:00 /bin/bash
root        15  0.0  0.0  51752  1708 pts/0    R+   07:16   0:00 ps -aux

12.2 在别的终端查看该容器的运行状态，该容器处于运行状态

[root@Tang ~]# w
 15:17:31 up 16 days,  1:58,  2 users,  load average: 0.04, 0.04, 0.05
USER     TTY      FROM             LOGIN@   IDLE   JCPU   PCPU WHAT
root     pts/0    172.16.141.198   13:12   59.00s  1.16s  0.03s /bin/bash
root     pts/1    172.16.141.198   13:50    3.00s  0.12s  0.02s w
[root@Tang ~]# docker container ps 
CONTAINER ID        IMAGE               COMMAND             CREATED              STATUS              PORTS               NAMES
57bd8a923604        myap:v2             "/bin/bash"         About a minute ago   Up About a minute                       mycentos

12.3 在 12.1 的基础，exit 退出 /bin/bash 进程

[root@Tang ~]# docker container run --name mycentos -it myap:v2 /bin/bash
[root@57bd8a923604 /]# ps -aux
USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
root         1  1.0  0.0  11828  1880 pts/0    Ss   07:16   0:00 /bin/bash
root        15  0.0  0.0  51752  1708 pts/0    R+   07:16   0:00 ps -aux
[root@57bd8a923604 /]# exit
exit

12.4 此时，查看此容易已经处于退出状态

[root@Tang ~]# docker container ps 
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS               NAMES
[root@Tang ~]# docker container ps -a
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                        PORTS               NAMES
57bd8a923604        myap:v2             "/bin/bash"         4 minutes ago       Exited (130) 55 seconds ago                       mycentos

12.5 可以使用 11 节介绍的方法，把容器和当前终端剥离
