* migration: add possibility to restore a container with a new nameAdrian Reber2019-06-04
| | | | | | | | | | | | | | | | | | | | The option to restore a container from an external checkpoint archive (podman container restore -i /tmp/checkpoint.tar.gz) restores a container with the same name and same ID as id had before checkpointing. This commit adds the option '--name,-n' to 'podman container restore'. With this option the restored container gets the name specified after '--name,-n' and a new ID. This way it is possible to restore one container multiple times. If a container is restored with a new name Podman will not try to request the same IP address for the container as it had during checkpointing. This implicitly assumes that if a container is restored from a checkpoint archive with a different name, that it will be restored multiple times and restoring a container multiple times with the same IP address will fail as each IP address can only be used once.

* Added support to migrate containersAdrian Reber2019-06-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds an option to the checkpoint command to export a checkpoint into a tar.gz file as well as importing a checkpoint tar.gz file during restore. With all checkpoint artifacts in one file it is possible to easily transfer a checkpoint and thus enabling container migration in Podman. With the following steps it is possible to migrate a running container from one system (source) to another (destination). Source system: * podman container checkpoint -l -e /tmp/checkpoint.tar.gz * scp /tmp/checkpoint.tar.gz destination:/tmp Destination system: * podman pull 'container-image-as-on-source-system' * podman container restore -i /tmp/checkpoint.tar.gz The exported tar.gz file contains the checkpoint image as created by CRIU and a few additional JSON files describing the state of the checkpointed container. Now the container is running on the destination system with the same state just as during checkpointing. If the container is kept running on the source system with the checkpoint flag '-R', the result will be that the same container is running on two different hosts.

In main_local we still retrieve the list of conmon pid files and use it from the rootless package. In addition, create a temporary user namespace for reading these files, as the unprivileged user might not have enough privileges for reading the conmon pid file, for example when running with a different uidmap and root in the container is different than the rootless user.

The pause process is created immediately on reload, and all successive Podman processes will refer to it for joining the user&mount namespace. This solves all the race conditions we had on joining the correct namespaces using the conmon processes. As a fallback if the join fails for any reason (e.g. the pause process was killed), then we try to join the running containers as we were doing before.
