docker删除容器
```
正常删除
docker rm nginx-cntf2
docker rm 31a3e8eb4b94
强制删除
[root@localhost ~]# docker rm 9b7a95f7458e

docker容器进入和退出
```
创建容器并进入
docker run -it --name nginx1010 nginx bash
docker run -it --name centos1011 centos /bin/bash
手动方式进入
以一个守护进程启动容器
[root@localhost ~]# docker run -itd --name cntf-nginx1 nginx bash
a6151efb502f01ed037c9afb2c48fbc5eb0db53c8e27110967830140df53ba02

[root@localhost ~]# docker ps -a

[root@localhost ~]# docker exec -it cntf-nginx1 bash

```
基于容器创建镜像
```
方法一
首先进入某个容器进行一序列操作，然后退出，执行如下命令
docker commit -m "vim-net-tools" -a "cntf" 9e91890fbdba cntf1
-m 指容器里面装了哪些东西，这里是描述
-a 作者的信息
cntf1 这是创建新的镜像自定义的一个名称
根据镜像生成容器，然后进入
docker run -it --name centos-nettools cntf1 /bin/bash
方法二
导出,名称centos-nettools.tar
docker export 6b948eac3524 > centos-nettools.tar
导入,名称centosnettools1015
cat centos-nettools.tar | docker import centos-nettools.tar centosnettools1015
查看是否成功
[root@localhost ~]# docker images
