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**. + +**--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. + +## EXAMPLE + +podman container restore mywebserver + +podman container restore 860a4b23 + +## SEE ALSO +podman(1), podman-container-checkpoint(1) + +## HISTORY +September 2018, Originally compiled by Adrian Reber <areber@redhat.com> |
