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⟩.

       --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.
