How to Export Docker Container?

The docker export command does not export the contents of volumes associated with the container. If a volume is mounted on top of an existing directory in the container, docker export will export the contents of the underlying directory, not the contents of the volumes.

--output, -o   Write to a file, instead of STDOUT

$ docker export red_panda (greaterthan angle bracket symbol) latest.tar 

or

$ docker export --output="latest.tar" red_panda

Export Commands:

docker export c1 > c1backup.tar

docker export -o='c2backup.tar' c1

[root@localhost ~]# docker images |grep c1backup.tar

[root@localhost ~]# ls

anaconda-ks.cfg  c1backup.tar  Dockerfile  hello-world

Import Commands:

[root@localhost ~]# docker import c1backup.tar backup:v1
