Docker daemon. After checkpoint, the Docker daemon thinks that the
container has exited. After restore, the Docker daemon doesn't know that
the container is running again. Therefore, commands such as
''docker ps ''and ''docker logs '' will not work correctly.
External C/R was done as a proof-of-concept.
'''Native C/R''' using
''docker checkpoint '' and ''docker restore '' commands.
Because the Docker daemon is involved in both checkpoint and restore,
its notion of the container state will be consistent and commands such as
''docker ps '' and ''docker logs '' will work.
Native C/R is work in progress, say pre-alpha quality. You can
Work in underway to integrate C/R into the new libcontainer.
