docker container and carve mirror, can be understood as the container is a simple example of the operation, the desired image is a running instance of static files.
Import and export operations can be done either on the container, may be the mirror operation. The difference is that the mirror can be exported at any time before they can be exported after the container must be stopped, otherwise not up and running when you export and then import the file, then import the container is mirrored not run directly. It need only be run after run.
Import container export
First check the operation of the vessel
docker ps -a
Add the -a parameter represents the view of all vessels, without - A parameter represents the view only vessel in operation
STATUS column have UP containers that represent the words of the running
Stop the container
docker stop testnginx
Export to a file container
docker export testnginx > nginx.tar
Nginx.tar then transmits the file to the other host docker, into a container, the container run
After the name into a vessel, 123 is introduced, after the introduction of the mirror type
docker import nginx.tar 123
View mirror after import
The image produced is a container operation
I do not know why the vessel can not run, has been in a state of E xited (0), there is the power of God, then please advise
