[root@docker01 ~]#

docker進(jìn)入容器的方法：

進(jìn)入容器的目的：排錯(cuò)，調(diào)試

方法一：docker exec [OPTIONS] CONTAINER COMMAND [ARG...]

例子：docker exec -it 容器id或容器名稱 /bin/bash
進(jìn)入容器默認(rèn)初始命令為/bin/bash，如下：

[root@docker01 ~]# docker run -it centos:6.8
[root@512d307de28d /]# exit
exit
[root@docker01 ~]# docker ps -a
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                        PORTS               NAMES
512d307de28d        centos:6.8          "/bin/bash"              13 seconds ago      Exited (0) 3 seconds ago                          dreamy_banzai
a2752e2fef9e        centos:6.8          "/bin/bash"              8 minutes ago       Exited (127) 5 minutes ago                        fervent_galois
[root@docker01 ~]

[root@docker01 ~]# docker container exec -it 2d50be31e6f2 /bin/bash
[root@2d50be31e6f2 /]#

方法二：docker attach [OPTIONS] CONTAINER

例子： docker attach 容器id或容器名字
nsenter(安裝yum install -y util-linux 棄用)

[root@docker01 ~]# docker container attach 2d50be31e6f2
[root@2d50be31e6f2 /]#

該容器只有兩個(gè)進(jìn)程一個(gè)是：/bin/bash，另一個(gè)是：運(yùn)行命令進(jìn)程
attach與exec的區(qū)別：attach與run采用的是同一個(gè)終端，相當(dāng)于同一個(gè)線程，如果采用多個(gè)窗口開發(fā)，則在一邊輸入命令，另一邊會(huì)同步出現(xiàn)。而exec不是與run同一個(gè)終端，每次采用exec連接容器時(shí)，都會(huì)重新分配終端（線程），不會(huì)導(dǎo)致輸入命令同步的問題，所以建議采用exec連接進(jìn)入容器，否則可能導(dǎo)致誤操作。

Docker ps命令解釋：

[root@docker01 ~]# docker ps -a -l --no-trunc
CONTAINER ID                                                       IMAGE               COMMAND             CREATED             STATUS                     PORTS               NAMES
2d50be31e6f26b029f3954692f620bf1bbec32daef11b6c6daeba1846566b2d5   centos:6.8          "/bin/bash"         26 minutes ago      Exited (0) 2 minutes ago                       peaceful_booth

-a :顯示所有的容器，包括未運(yùn)行的。
-f :根據(jù)條件過(guò)濾顯示的內(nèi)容。
--format :指定返回值的模板文件。
-l :顯示最近創(chuàng)建的容器。
-n :列出最近創(chuàng)建的n個(gè)容器。
--no-trunc :不截?cái)噍敵觥?br> -q :靜默模式，只顯示容器編號(hào)。
-s :顯示總的文件大小。

docker容器的核心理念

docker的本質(zhì)是：在隔離的環(huán)境運(yùn)行的一個(gè)進(jìn)程所以：docker容器內(nèi)的第一個(gè)進(jìn)程必須一直處于前臺(tái)運(yùn)行的狀態(tài)（必須夯住），否則這個(gè)容器，就會(huì)處于退出狀態(tài)！
正常情況下：docker run -d centos:6.8 是無(wú)法讓centos在后臺(tái)運(yùn)行，能夯住的命令：tail -f /-F

[root@docker01 ~]# docker run -d centos:6.8 
a374f287482a063ced2831335bbeec9034524bc651d978037359c5b9fa537389

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS                           PORTS               NAMES
