--keep, -k

Keep all temporary log and statistics files created by CRIU during checkpointing. These files are not deleted if checkpointing fails for further debugging. If checkpointing succeeds these files are theoretically not needed, but if these files are needed Podman can keep the files for further analysis.

--all, -a

Checkpoint all running containers.

--latest, -l

Instead of providing the container name or ID, checkpoint the last created container.

The latest option is not supported on the remote client.

--leave-running, -R

Leave the container running after checkpointing instead of stopping it.

--tcp-established

Checkpoint a container with established TCP connections. If the checkpoint image contains established TCP connections, this options is required during restore. Defaults to not checkpointing containers with established TCP connections.

--export, -e

Export the checkpoint to a tar.gz file. The exported checkpoint can be used to import the container on another system and thus enabling container live migration. This checkpoint archive also includes all changes to the container's root file-system, if not explicitly disabled using --ignore-rootfs

--ignore-rootfs

This only works in combination with --export, -e. If a checkpoint is exported to a tar.gz file it is possible with the help of --ignore-rootfs to explicitly disable including changes to the root file-system into the checkpoint archive file.

--ignore-volumes

This option must be used in combination with the --export, -e option. When this option is specified, the content of volumes associated with the container will not be included into the checkpoint tar.gz file.

--pre-checkpoint, -P

Dump the container's memory information only, leaving the container running. Later operations will supersede prior dumps. It only works on runc 1.0-rc3 or higher.

--with-previous

Check out the container with previous criu image files in pre-dump. It only works without --pre-checkpoint or -P. It only works on runc 1.0-rc3 or higher.
