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|ignore.
              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⟩.
