% runc-checkpoint "8"
runc-checkpoint - checkpoint a running container
runc checkpoint [option ...] container-id
The checkpoint command saves the state of the running container instance with the help of criu(8) tool, to be restored later.
--image-path path : Set path for saving criu image files. The default is ./checkpoint.
--work-path path : Set path for saving criu work files and logs. The default is to reuse the image files directory.
--parent-path path : Set path for previous criu image files, in pre-dump.
--leave-running : Leave the process running after checkpointing.
--tcp-established : Allow checkpoint/restore of established TCP connections. See criu --tcp-establised option.
--ext-unix-sk : Allow checkpoint/restore of external unix sockets. See criu --ext-unix-sk option.
--shell-job : Allow checkpoint/restore of shell jobs.
--lazy-pages : Use lazy migration mechanism. See criu --lazy-pages option.
--status-fd fd : Pass a file descriptor fd to criu. Once lazy-pages server is ready, criu writes \0 (a zero byte) to that fd. Used together with --lazy-pages.
--page-server IP-address:port : Start a page server at the specified IP-address and port. This is used together with criu lazy-pages. See criu lazy migration.
--file-locks : Allow checkpoint/restore of file locks. See criu --file-locks option.
--pre-dump : Do a pre-dump, i.e. dump container's memory information only, leaving the container running. See criu iterative migration.
--manage-cgroups-mode soft|full|strict. : Cgroups mode. Default is soft. See criu --manage-cgroups option.
--empty-ns namespace : Checkpoint a namespace, but don't save its properties. See criu --empty-ns option.
--auto-dedup : Enable auto deduplication of memory images. See criu --auto-dedup option.
