## 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. 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.
|
