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⟩.
