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⟩.

       --tcp-skip-in-flight
              Skip in-flight TCP connections. See criu --skip-in-flight option ⟨https://criu.org/CLI/opt/--skip-
              in-flight⟩.

       --link-remap
              Allow   one   to   link   unlinked   files  back  when  possible.  See  criu  --link-remap  option
              ⟨https://criu.org/CLI/opt/--link-remap⟩.

       --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⟩.
