I took the liberty of combining related checks together so as to avoid a little duplication; if this is not a Go best practice, I will revert. I also made a minor wording adjustment to an error message for clarity. Also: update wording of man page. Signed-off-by: Ed Santiago <santiago@redhat.com>

## NAME
|
|
podman\-container\-restore - Restores one or more running containers
|
|
|
|
## SYNOPSIS
|
|
**podman container restore** [*options*] *container* ...
|
|
|
|
## DESCRIPTION
|
|
Restores a container from a checkpoint. You may use container IDs or names as input.
|
|
|
|
## OPTIONS
|
|
**--keep**, **-k**
|
|
|
|
Keep all temporary log and statistics files created by CRIU during
|
|
checkpointing as well as restoring. These files are not deleted if restoring
|
|
fails for further debugging. If restoring succeeds these files are
|
|
theoretically not needed, but if these files are needed Podman can keep the
|
|
files for further analysis. This includes the checkpoint directory with all
|
|
files created during checkpointing. The size required by the checkpoint
|
|
directory is roughly the same as the amount of memory required by the
|
|
processes in the checkpointed container.
|
|
|
|
Without the **-k**, **--keep** option the checkpoint will be consumed and cannot be used
|
|
again.
|
|
|
|
**--all**, **-a**
|
|
|
|
Restore all checkpointed containers.
|
|
|
|
**--latest**, **-l**
|
|
|
|
Instead of providing the container name or ID, restore the last created container.
|
|
|
|
The latest option is not supported on the remote client.
|
|
|
|
**--tcp-established**
|
|
|
|
Restore a container with established TCP connections. If the checkpoint image
|
|
contains established TCP connections, this option is required during restore.
|
|
If the checkpoint image does not contain established TCP connections this
|
|
option is ignored. Defaults to not restoring containers with established TCP
|
|
connections.
|
|
|
|
**--import, -i**
|
|
|
|
Import a checkpoint tar.gz file, which was exported by Podman. This can be used
|
|
to import a checkpointed container from another host. Do not specify a *container*
|
|
argument when using this option.
|
|
|
|
**--name, -n**
|
|
|
|
This is only available in combination with **--import, -i**. If a container is restored
|
|
from a checkpoint tar.gz file it is possible to rename it with **--name, -n**. This
|
|
way it is possible to restore a container from a checkpoint multiple times with different
|
|
names.
|
|
|
|
If the **--name, -n** option is used, Podman will not attempt to assign the same IP
|
|
address to the container it was using before checkpointing as each IP address can only
|
|
be used once and the restored container will have another IP address. This also means
|
|
that **--name, -n** cannot be used in combination with **--tcp-established**.
|
|
