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⟩.
