% podman-container-restore(1) ## NAME podman\-container\-restore - Restores one or more containers from a checkpoint ## SYNOPSIS **podman container restore** [*options*] *container* [*container* ...] ## DESCRIPTION **podman container restore** restores a container from a checkpoint. The *container IDs* or *names* are used as input. ## OPTIONS #### **--all**, **-a** Restore all checkpointed *containers*.\ The default is **false**.\ *IMPORTANT: This OPTION does not need a container name or ID as input argument.* #### **--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 **--keep**, **-k** option the checkpoint will be consumed and cannot be used again.\ The default is **false**. #### **--latest**, **-l** Instead of providing the *container ID* or *name*, use the last created *container*. If other tools than Podman are used to run *containers* such as `CRI-O`, the last started *container* could be from either tool.\ The default is **false**.\ *IMPORTANT: This OPTION is not available with the remote Podman client. This OPTION does not need a container name or ID as input argument.* #### **--ignore-rootfs** 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*.\ The default is **false**.\ *IMPORTANT: This OPTION is only available in combination with **--import, -i**.* #### **--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. The default is **false**. #### **--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. The default is **false**. #### **--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.\ The default is **false**. #### **--import**, **-i**=*file* Import a checkpoint tar.gz file, which was exported by Podman. This can be used to import a checkpointed *container* from another host.\ *IMPORTANT: This OPTION does not need a container name or ID as input argument.* #### **--import-previous**=*file* 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**=*name* 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**.\ *IMPORTANT: This OPTION is only available in combination with **--import, -i**.* #### **--pod**=*name* Restore a container into the pod *name*. The destination pod for this restore has to have the same namespaces shared as the pod this container was checkpointed from (see **[podman pod create --share](podman-pod-create.1.md#--share)**). *IMPORTANT: This OPTION is only available in combination with **--import, -i**.* This option requires at least CRIU 3.16. #### **--publish**, **-p**=*port* Replaces the ports that the *container* publishes, as configured during the initial *container* start, with a new set of port forwarding rules. For more details please see **[podman run --publish](podman-run.1.md#--publish)**. #### **--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.\ The default is **false**. ## EXAMPLE Restores the container "mywebserver". ``` # podman container restore mywebserver ``` Import a checkpoint file and a pre-checkpoint file. ``` # podman container restore --import-previous pre-checkpoint.tar.gz --import checkpoint.tar.gz ``` Remove the container "mywebserver". Make a checkpoint of the container and export it. Restore the container with other port ranges from the exported file. ``` $ podman run --rm -p 2345:80 -d webserver # podman container checkpoint -l --export=dump.tar # podman container restore -p 5432:8080 --import=dump.tar ``` ## SEE ALSO **[podman(1)](podman.1.md)**, **[podman-container-checkpoint(1)](podman-container-checkpoint.1.md)**, **[podman-run(1)](podman-run.1.md)**, **[podman-pod-create(1)](podman-pod-create.1.md)** ## HISTORY September 2018, Originally compiled by Adrian Reber
