Docker导出容器到本地文件

不管是容器不是处于运行状态，都可以导出！

首先查看那容器状态

[root@docker ~]# docker ps -a

导出一个终止状态的：

[root@docker ~]# docker export 940e7e >fwc_rongqi.tar
[root@docker ~]# ls
anaconda-ks.cfg fuchao_latest fwc_rongqi.tar
[root@docker ~]#

导出一个运行状态的：

[root@docker ~]# docker export 5dbb94 >fwc_run.tar
[root@docker ~]# ls
anaconda-ks.cfg fuchao_latest fwc_rongqi.tar fwc_run.tar
[root@docker ~]#
