Docker Experimental with native checkpoint/restore support using CRIU.

Last Update: 2015-08-12

For easy testing and experimenting, below you can find a compiled version of Docker Experimental v1.9.0 with native checkpoint and restore functionality (compiled from the cr-combined branch of boucher/docker).

Also, a compiled version of CRIU v1.6 and libprotobuf (required by CRIU), courtesy of @SaiedKazemi (see notes at: https://github.com/SaiedKazemi/docker/releases).

Example use:

docker run -d --publish-service test busybox /bin/sh -c 'i=0; while true; do echo $i; i=$(expr $i + 1); sleep 1; done'

If you examine the logs at this point, you should see prints of an increasing integer counter.

docker checkpoint <id>
docker restore <id>

Checking the logs again should show that the counter is still increasing. (Waiting a bit between checkpoint and restore can increase your confidence that the process actually stopped for a while)

NOTE: networking is currently not working. Once you restore a container, it will not have network connectivity.

NOTE: you may need additional dependencies:
