runc-checkpoint(8)          System Manager's Manual         runc-checkpoint(8)



NAME
       runc-checkpoint - checkpoint a running container



SYNOPSIS
       runc checkpoint [option ...] container-id



DESCRIPTION
       The checkpoint command saves the state of the running container
       instance with the help of criu(8) tool, to be restored later.



OPTIONS
       --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
              <https://criu.org/CLI/opt/--tcp-established>.


       --ext-unix-sk
              Allow checkpoint/restore of external unix sockets. See criu
              --ext-unix-sk option <https://criu.org/CLI/opt/--ext-unix-sk>.


       --shell-job
              Allow checkpoint/restore of shell jobs.


       --lazy-pages
              Use lazy migration mechanism. See criu --lazy-pages option
              <https://criu.org/CLI/opt/--lazy-pages>.


       --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
              <https://criu.org/Lazy_migration>.


       --file-locks
              Allow checkpoint/restore of file locks. See criu --file-locks
              option <https://criu.org/CLI/opt/--file-locks>.


       --pre-dump
              Do a pre-dump, i.e. dump container's memory information only,
              leaving the container running. See criu iterative migration
              <https://criu.org/Iterative_migration>.


       --manage-cgroups-mode soft|full|strict.
              Cgroups mode. Default is soft. See criu --manage-cgroups option
              <https://criu.org/CLI/opt/--manage-cgroups>.


       --empty-ns namespace
              Checkpoint a namespace, but don't save its properties. See criu
              --empty-ns option <https://criu.org/CLI/opt/--empty-ns>.


       --auto-dedup
              Enable auto deduplication of memory images. See criu --auto-
              dedup option <https://criu.org/CLI/opt/--auto-dedup>.
