* 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.

* | rootless: new function to join existing conmon processesGiuseppe Scrivano2019-05-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | move the logic for joining existing namespaces down to the rootless package. 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.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we supercede low-priority mounts and volumes (image volumes, and volumes sourced from --volumes-from) with higher-priority ones (the --volume and --mount flags), we always replaced lower-priority mounts of the same type (e.g. a user mount to /tmp/test1 would supercede a volumes-from mount to the same destination). However, we did not supercede the opposite type - a named volume from image volumes at /tmp/test1 would be allowed to remain and create a conflict, preventing container creation. Solve this by destroying opposite types before merging (we can't do it in the same loop, as then named volumes, which go second, might trample changes made by mounts).

|\ \ \ | | | | | | | | rootless: use a pause process to keep namespaces alive

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | add a shortcut for joining immediately the namespace so we don't need to re-exec Podman.

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.
