<br>
We have started to test docker checkpoint with a real-world
workloads.<br>
<br>
Until now we tried with acmeair-nodejs [1] with the
microservice usecase.<br>
<br>
This application creates 10 containers and they interact
between each other with volumes and network<br>
<br>
connection. The checkpoint war not successful. Here, the error
message in restore:<br>
<br>
(00.195135) 1: No iptables-9.img image<br>
<br>
(00.195136) 1: Error (criu/include/image.h:144): BUG at
criu/include/image.h:144<br>
<br>
(00.195171) Error (criu/cr-restore.c:1284): 15638 killed by
signal 127: Unknown signal 127<br>
<br>
(00.315156) Error (criu/mount.c:2980): mnt: Can't remove the
directory /tmp/.criu.mntns.C12otH: No such file or directory<br>
<br>
(00.315160) Error (criu/cr-restore.c:2152): Restoring FAILED.<br>
<br>
We tested with criu version:<br>
<br>
Version: 3.4<br>
<br>
GitID: v3.4-224-g3706af7b<br>
<br>
1) Any ideas for what could have caused the error?<br>
<br>
Additionally, we have two more general questions.<br>
<br>
2) How should we perform checkpoint for applications with
multiple container interaction?<br>
<br>
3) For which use cases have you already tried the C/R?<br>
<br>
We saw this overview in your wiki [2], but it seems to be not
recently updated.<br>
<br>
