NAME

podman-container-checkpoint - Checkpoints one or more running containers

SYNOPSIS

podman container checkpoint [options] container ...

DESCRIPTION

Checkpoints all the processes in one or more containers. You may use container IDs or names as input.

OPTIONS

--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.

EXAMPLE

podman container checkpoint mywebserver

podman container checkpoint 860a4b23
