## NAME
|
|
podman\-container\-restore - Restores one or more containers from a checkpoint
|
|
|
|
## 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.
|
|
|
|
#### **--import-previous**
|
|
|
|
Import a pre-checkpoint tar.gz file which was exported by Podman. This option
|
|
must be used with **-i** or **--import**. It only works on runc 1.0-rc3 or higher.
|
|
|
|
#### **--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**.
|
|
|
|
#### **--ignore-rootfs**
|
|
|
|
This is only available in combination with **--import, -i**. If a container is restored
|
|
from a checkpoint tar.gz file it is possible that it also contains all root file-system
|
|
changes. With **--ignore-rootfs** it is possible to explicitly disable applying these
|
|
root file-system changes to the restored container.
|
|
|
|
#### **--ignore-static-ip**
|
|
|
|
If the container was started with **--ip** the restored container also tries to use that
|
|
IP address and restore fails if that IP address is already in use. This can happen, if
|
|
a container is restored multiple times from an exported checkpoint with **--name, -n**.
|
|
|
|
Using **--ignore-static-ip** tells Podman to ignore the IP address if it was configured
|
|
with **--ip** during container creation.
|
|
|
|
#### **--ignore-static-mac**
|
|
|
|
If the container was started with **--mac-address** the restored container also
|
|
tries to use that MAC address and restore fails if that MAC address is already
|
|
in use. This can happen, if a container is restored multiple times from an
|
|
exported checkpoint with **--name, -n**.
|
|
|
|
Using **--ignore-static-mac** tells Podman to ignore the MAC address if it was
|
|
configured with **--mac-address** during container creation.
|
|
|
|
#### **--ignore-volumes**
|
|
|
|
This option must be used in combination with the **--import, -i** option.
|
|
When restoring containers from a checkpoint tar.gz file with this option,
|
|
the content of associated volumes will not be restored.
|
|
|
|
