1.13 experimental: checkpoint/restore not working

[thaJeztah]

Docker 1.13 adds experimental support for checkpoint/restore, using CRIU (https://criu.org), see Docker Checkpoint & Restore.

This feature currently cannot be used on the Docker for Mac "beta" / "master" channel, because CRIU is not available in the VM.

Expected behavior

$ docker run --security-opt=seccomp:unconfined --name cr -d busybox /bin/sh -c 'i=0; while true; do echo $i; i=$(expr $i + 1); sleep 1; done'

$ docker checkpoint create cr checkpoint1

Actual behavior

$ docker run --security-opt=seccomp:unconfined --name cr -d busybox /bin/sh -c 'i=0; while true; do echo $i; i=$(expr $i + 1); sleep 1; done'

$ docker checkpoint create cr checkpoint1
Error response from daemon: Cannot checkpoint container cr: rpc error: code = 2 desc = exit status 1: "Unable to execute CRIU command: criu\n"

Information

Version 1.13.0-rc4-beta34 (14831)
Channel: Master
5987079516

Steps to reproduce the behavior

See above

CRIU should be available on Docker for Mac / Docker for Windows, or a note should be added to the "known issues" section
https://docs.docker.com/docker-for-mac/troubleshoot/#/known-issues

I opened an internal issue for this as well

Hi
I am hitting the same issue with Docker 1.13 experimental with criu version v2.10-1-gd9486bd.
Any solution for this?
I am using Ubuntu 16 VM to try this out.

Thanks

@smakam if you're getting the same error as above, then criu is not installed, however, the issue here is purely for Docker for Mac, which currently doesn't have support fro criu, so not directly related to your issue

[smakam]

@thaJeztah Thanks for the response. Sorry, it was a mistake on my part. I had a criu installed, but I had not done "make install" that was causing the issue. After doing "make install", its working fine now.

I was able to get this working this morning. There's a pre-built version of criu in the alpine testing repository, but it doesn't quite work. I've attached an updated binary that should work if put into the docker for mac vm: criu-alpine.zip

Here's the other libraries you'll need installed:

/ # ldd /usr/sbin/criu
        /lib/ld-musl-x86_64.so.1 (0x56394a323000)
        libprotobuf-c.so.1 => /usr/lib/libprotobuf-c.so.1 (0x7f1c09b22000)
        libnl-3.so.200 => /usr/lib/libnl-3.so.200 (0x7f1c09904000)
        libnet.so.1 => /usr/lib/libnet.so.1 (0x7f1c096ec000)
        libc.musl-x86_64.so.1 => /lib/ld-musl-x86_64.so.1 (0x56394a323000)

The other thing I had to do to get it working was upgrade the version of tar, with:

apk --update add tar

It would be great to get this built into docker for mac and have checkpoint/restore work out of the box!

@boucher can you submit a patch to Alpine to fix the upstream? I can't use a binary.

[avagin]

I pushed all required patches into the alpine branch:
https://github.com/avagin/criu/commits/alpine

And I think it would be better to wait two weeks to the next CRIU release (2.11).
