1.创建容器

1.前台运行创建

注意:下面是创建容器并进入容器,当exit退出容器后,容器就不在运行,需要使用-d选项,后台运行

[root@localhost ~]# docker run -i -t centos:7 /bin/bash
[root@4af91bbbc860 /]# ps -ef
UID         PID   PPID  C STIME TTY          TIME CMD
root          1      0  0 03:19 pts/0    00:00:00 /bin/bash
root         15      1  0 03:19 pts/0    00:00:00 ps -ef
[root@4af91bbbc860 /]# exit
exit
[root@localhost ~]# docker ps -a
CONTAINER ID   IMAGE      COMMAND       CREATED         STATUS                     PORTS     NAMES
4af91bbbc860   centos:7   "/bin/bash"   7 minutes ago   Exited (0) 8 seconds ago             naughty_meitner
​
选项:
-name:指定容器名称,默认是随机名字
-i:创建一个交互式容器
-t:为容器分配一个伪终端,绑定到容器的标准输入上
-d:后台运行容器

2.后台运行创建

[root@localhost ~]# docker run -itd --name centos7-1 centos:7 /bin/bash
08b6e56e54f2d645601cd71020a922c7b5f916725401b7408e358a782a965284
[root@localhost ~]# docker ps -a
CONTAINER ID   IMAGE      COMMAND       CREATED         STATUS                          PORTS     NAMES
08b6e56e54f2   centos:7   "/bin/bash"   2 seconds ago   Up 2 seconds                              centos7-1
4af91bbbc860   centos:7   "/bin/bash"   8 minutes ago   Exited (0) About a minute ago       naughty_meitner
​
选项:
-name:指定容器名称,默认是随机名字
-i:创建一个交互式容器
-t:为容器分配一个伪终端,绑定到容器的标准输入上
-d:后台运行容器

2.查看容器的ID

注:可以用于删除容器时,过滤

[root@localhost ~]# docker ps -q
08b6e56e54f2

3.管理容器

1.开启容器

[root@localhost ~]# docker start 4af91bbbc860
4af91bbbc860
[root@localhost ~]# docker ps -a
CONTAINER ID   IMAGE      COMMAND       CREATED          STATUS          PORTS     NAMES

4af91bbbc860   centos:7   "/bin/bash"   38 minutes ago   Up 1 second               naughty_meitner

2.关闭容器

[root@localhost ~]# docker stop 08b6e56e54f2
08b6e56e54f2
[root@localhost ~]# docker ps -a
CONTAINER ID   IMAGE      COMMAND       CREATED          STATUS                        PORTS     NAMES
08b6e56e54f2   centos:7   "/bin/bash"   30 minutes ago   Exited (137) 10 seconds ago             centos7-1
4af91bbbc860   centos:7   "/bin/bash"   39 minutes ago   Up 53 seconds                           naughty_meitner

3.强制关闭容器

[root@localhost ~]# docker kill 4af91bbbc860
4af91bbbc860
[root@localhost ~]# docker ps -a
CONTAINER ID   IMAGE      COMMAND       CREATED          STATUS                        PORTS     NAMES
08b6e56e54f2   centos:7   "/bin/bash"   31 minutes ago   Exited (137) 51 seconds ago             centos7-1
4af91bbbc860   centos:7   "/bin/bash"   39 minutes ago   Exited (137) 1 second ago               naughty_meitner

4.重启容器

[root@localhost ~]# docker restart 4af91bbbc860
4af91bbbc860
[root@localhost ~]# docker ps -a
CONTAINER ID   IMAGE      COMMAND       CREATED          STATUS                            PORTS     NAMES

4af91bbbc860   centos:7   "/bin/bash"   40 minutes ago   Up 7 seconds                                naughty_meitner

4.查看容器信息

1.查看所有信息

[root@localhost ~]# docker inspect 4af91bbbc860

2.查看容器IP

[root@localhost ~]# docker inspect -f '{
   
   {.NetworkSettings.IPAddress}}' 4af91bbbc860
172.17.0.2

3.查看PID

[root@localhost ~]# docker inspect -f '{
   
   {.State.Pid}}' 4af91bbbc860
72633

5.进入容器

注意:进入当前的伪终端,如果exit退出之后,当前的容器也会随之关闭,因为当前只存在一个终端。

1.进入当前的伪终端中

[root@localhost ~]# docker attach 4af91bbbc860
[root@4af91bbbc860 /]# exit
exit
[root@localhost ~]# docker ps -a
CONTAINER ID   IMAGE      COMMAND       CREATED          STATUS                             PORTS     NAMES
08b6e56e54f2   centos:7   "/bin/bash"   42 minutes ago   Exited (137) 11 minutes ag     o             centos7-1
4af91bbbc860   centos:7   "/bin/bash"   50 minutes ago   Exited (0) 5 seconds ago                     naughty_meitner

2.创建一个新的伪终端并进入

[root@localhost ~]# docker exec -it 4af91bbbc860 /bin/bash
[root@4af91bbbc860 /]# exit
exit
[root@localhost ~]# docker ps -a
CONTAINER ID   IMAGE      COMMAND       CREATED          STATUS                        PORTS     NAMES
08b6e56e54f2   centos:7   "/bin/bash"   43 minutes ago   Exited (137) 13 minutes ago             centos7-1
4af91bbbc860   centos:7   "/bin/bash"   51 minutes ago   Up 28 seconds                           naughty_meitner

6.导出\导入容器

1.导出容器

将当前容器导出到本地

[root@localhost ~]# docker export 4af91bbbc860 > centos7.tar
[root@localhost ~]# ls
anaconda-ks.cfg  centos7.tar  original-ks.cfg

2.导入容器

将当前容器导入为竟镜像,然后再基于这个镜像创建容器

[root@localhost ~]# cat centos7.tar | docker import - centos7:test
sha256:d0373e6a70dc1413fa992d11c40b9260fe742db22196429835d33b9cc3eb2135
[root@localhost ~]# docker images
REPOSITORY                                          TAG       IMAGE ID       CREATED          SIZE
centos7                                             test      d0373e6a70dc   11 seconds ago   204MB
 
 

7.删除容器

1.删除单个容器

[root@localhost ~]# docker rm -f 4af91bbbc860
​
选项:
-f:强制删除

2.删除多个容器

[root@localhost ~]# docker rm -f 4af91bbbc860  08b6e56e54f2

3.删除全部容器

[root@localhost ~]# docker rm -f  $(docker ps -aq)
