容器基本操作：
创建一个容器
[root@ct7-mb ~]# docker run -itd ubuntu
3635f4dd3ae30a4377fc4f2eafc191b7890bbe5873bb4e5f9e5077f794466ec4
查看容器进程
[root@ct7-mb ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
3635f4dd3ae3 ubuntu "/bin/bash" 8 seconds ago Up 6 seconds romantic_lamarr
[root@ct7-mb ~]# docker ps -l
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
3635f4dd3ae3 ubuntu "/bin/bash" 15 seconds ago Up 13 seconds romantic_lamarr
[root@ct7-mb ~]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
3635f4dd3ae3 ubuntu "/bin/bash" About a minute ago Up About a minute
开启容器：
[root@ct7-mb ~]# docker start romantic_lamarr
romantic_lamarr
进入容器进行操作：
[root@ct7-mb ~]# docker attach romantic_lamarr
root@3635f4dd3ae3:/# ls
bin dev home lib64 mnt proc run srv tmp var
boot etc lib media opt root sbin sys usr
root@3635f4dd3ae3:/# exit
exit
停止容器
[root@ct7-mb ~]# docker stop romantic_lamarr
romantic_lamarr
删除容器
[root@ct7-mb ~]# docker rm romantic_lamarr
romantic_lamarr
[root@ct7-mb ~]# docker start romantic_lamarr
Error response from daemon: No such container: romantic_lamarr
Error: failed to start containers: romantic_lamarr
PS：使用rm需要先停止使用容器（stop），强行删除可以加 -r 参数选项
重命名容器
[root@ct7-mb ~]# docker run -itd ubuntu
992dec8c882cbc3115045be8d7e76b496733e5996e4e083aebaa00e1ccef2a23
[root@ct7-mb ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
992dec8c882c ubuntu "/bin/bash" 5 seconds ago Up 3 seconds reverent_hamilton
[root@ct7-mb ~]# docker rename reverent_hamilton jinc
[root@ct7-mb ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
992dec8c882c ubuntu "/bin/bash" 22 seconds ago Up 21 seconds jinc

不进入容器执行命令（截取部分）
[root@ct7-mb ~]# docker exec jinc ls
bin
boot
dev
etc
容器中运行的进程
[root@ct7-mb ~]# docker top jinc

端口映射信息（没做映射，所以这里没有显示）
[root@ct7-mb ~]# docker port jinc
拷贝文件到容器
[root@ct7-mb ~]# touch a.txt
[root@ct7-mb ~]# docker cp a.txt jinc:/home
[root@ct7-mb ~]# docker exec jinc ls /home
a.txt
从容器拉取文件到本机
[root@ct7-mb ~]# docker cp jinc:/home/a.txt /tmp/
[root@ct7-mb ~]# ls /tmp/
a.txt
查看读写层操作（新增文件）
[root@ct7-mb ~]# docker diff jinc
C /home
A /home/a.txt
查看容器标准输出日志
[root@ct7-mb ~]# docker logs jinc
动态查看容器利用率
[root@ct7-mb ~]# docker stats jinc
CONTAINER ID NAME CPU % MEM USAGE / LIMIT MEM % NET I/O BLOCK I/O PIDS
992dec8c882c jinc 0.00% 404KiB / 1.779GiB 0.02% 648B / 0B 0B / 0B 1
静态查看容器利用率
[root@ct7-mb ~]# docker stats --no-stream jinc
CONTAINER ID NAME CPU % MEM USAGE / LIMIT MEM % NET I/O BLOCK I/O PIDS
992dec8c882c jinc 0.00% 404KiB / 1.779GiB 0.02% 648B / 0B 0B / 0B 1
动态修改容器硬件参数
[root@ct7-mb ~]# docker update --help
Usage: docker update [OPTIONS] CONTAINER [CONTAINER...]
Update configuration of one or more containers
Options:
--blkio-weight uint16 Block IO (relative weight), between 10 and
1000, or 0 to disable (default 0)
--cpu-period int Limit CPU CFS (Completely Fair Scheduler) period
--cpu-quota int Limit CPU CFS (Completely Fair Scheduler) quota
--cpu-rt-period int Limit the CPU real-time period in microseconds
--cpu-rt-runtime int Limit the CPU real-time runtime in microseconds
-c, --cpu-shares int CPU shares (relative weight)
--cpus decimal Number of CPUs
--cpuset-cpus string CPUs in which to allow execution (0-3, 0,1)
--cpuset-mems string MEMs in which to allow execution (0-3, 0,1)
--kernel-memory bytes Kernel memory limit
-m, --memory bytes Memory limit
--memory-reservation bytes Memory soft limit
--memory-swap bytes Swap limit equal to memory plus swap: '-1' to
enable unlimited swap
--restart string Restart policy to apply when a container exits
