Docker Checkpoint and Restore Containers Compile docker with checkpoint and restore enabled (ubuntu)
Example
In order to compile docker its recommended you have at least 2 GB RAM. Even with that it fails sometimes so its better to go for 4GB instead.
-
make sure git and make is installed
sudo apt-get install make git-core -y -
install a new kernel (at least 4.2)
sudo apt-get install linux-generic-lts-xenial -
reboot machine to have the new kernel active
sudo reboot -
compile
criuwhich is needed in order to rundocker checkpointsudo apt-get install libprotobuf-dev libprotobuf-c0-dev protobuf-c-compiler protobuf-compiler python-protobuf libnl-3-dev libcap-dev -y wget http://download.openvz.org/criu/criu-2.4.tar.bz2 -O - | tar -xj cd criu-2.4 make make install-lib make install-criu -
check if every requirement is fulfilled to run criu
sudo criu check -
compile experimental docker ( we need docker to compile docker)
cd ~ wget -qO- https://get.docker.com/ | sh sudo usermod -aG docker $(whoami)
-
At this point we have to logoff and login again to have a docker daemon. After relog continue with compile step
git clone https://github.com/boucher/docker cd docker git checkout docker-checkpoint-restore make #that will take some time - drink a coffee DOCKER_EXPERIMENTAL=1 make binary
-
We now have a compiled docker. Lets move the binaries. Make sure to replace
<version>with the version installedsudo service docker stop sudo cp $(which docker) $(which docker)_ ; sudo cp ./bundles/latest/binary-client/docker-<version>-dev $(which docker) sudo cp $(which docker-containerd) $(which docker-containerd)_ ; sudo cp ./bundles/latest/binary-daemon/docker-containerd $(which docker-containerd) sudo cp $(which docker-containerd-ctr) $(which docker-containerd-ctr)_ ; sudo cp ./bundles/latest/binary-daemon/docker-containerd-ctr $(which docker-containerd-ctr) sudo cp $(which docker-containerd-shim) $(which docker-containerd-shim)_ ; sudo cp ./bundles/latest/binary-daemon/docker-containerd-shim $(which docker-containerd-shim) sudo cp $(which dockerd) $(which dockerd)_ ; sudo cp ./bundles/latest/binary-daemon/dockerd $(which dockerd) sudo cp $(which docker-runc) $(which docker-runc)_ ; sudo cp ./bundles/latest/binary-daemon/docker-runc $(which docker-runc) sudo service docker start
Dont worry - we backed up the old binaries. They are still there but with an underscore added to its names (docker_).
Congratulation you now have an experimental docker with the ability to checkpoint a container and restore it.
Please note that experimental features are NOT ready for production
