Possible to make incremental checkpoints CRIU

Yeah, same concern.
what you need is predumm option.

1. one resource may help. github.com/xemul/p.haulp.haul make it possible to adjust predump request

2. runC with predump option.this is what you watch on youtube.15dockerCon.github.com/marcosnils/runc

Currently, we have serval ways to make docker checkpoint/restore.
a.Native way:github.com/boucher/docker/releases

docker checkpointdocker restore

b.runC way:github.com/marcosnils/cmtgithub.com/marcosnils/runc

runc checkpoint runc restore 

c.external way:

criu dump -o dump.log -v4 -t 15215 \  -D /tmp/m1  \  --root /var/lib/docker/aufs/mnt/container id  \  --manage-cgroups \  --evasive-devices \  --ext-mount-map /etc/resolv.conf:/etc/resolv.conf \  --ext-mount-map /etc/hosts:/etc/hosts \  --ext-mount-map /etc/hostname:/etc/hostname \  --ext-mount-map /etc/resolv.conf:/etc/resolv.conf

Basically, we would prefer the docker native and runc. But both do not support predump now.the hack way. github.com/marcosnils/runcbut I double the runC version is old.

To keep the process running try docker checkpoint create --leave-running=true
