* Initial implementation of renaming containersMatthew Heon2021-01-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Basic theory: We remove the container, but *only from the DB*. We leave it in c/storage, we leave the lock allocated, we leave it running (if it is). Then we create an identical container with an altered name, and add that back to the database. Theoretically we now have a renamed container. The advantage of this approach is that it doesn't just apply to rename - we can use this to make *any* configuration change to a container that does not alter its container ID. Potential problems are numerous. This process is *THOROUGHLY* non-atomic at present - if you `kill -9` Podman mid-rename things will be in a bad place, for example. Also, we can't rename containers that can't be removed normally - IE, containers with dependencies (pod infra containers, for example). The largest potential improvement will be to move the majority of the work into the DB, with a `RecreateContainer()` method - that will add atomicity, and let us remove the container without worrying about depencies and similar issues. Potential problems: long-running processes that edit the DB and may have an older version of the configuration around. Most notable example is `podman run --rm` - the removal command needed to be manually edited to avoid this one. This begins to get at the heart of me not wanting to do this in the first place... This provides CLI and API implementations for frontend, but no tunnel implementation. It will be added in a future release (just held back for time now - we need this in 3.0 and are running low on time). This is honestly kind of horrifying, but I think it will work.

The migration attempted to preserve compatibility by returning only one error, but that's not really a viable option as it can obscure the real reason that a pod is failing. Further, the code was not correctly handling the API's errors - Pod Start() will, on any container error, return a map of container ID to error populated for all container errors *and* return ErrPodPartialFail for overall error - the existing code did not handle the partial failure error and thus would never return container errors. Refactor the `play kube` API to include a set of errors for containers in each pod, so we can return all errors that occurred to the frontend and print them for the user, and correct the backend code so container errors are actually forwarded.

This patch enables container checkpoint/restore with named volumes by including the content of volumes in checkpoint file. On restore, volumes associated with container are created and their content is restored. The --ignore-volumes option is introduced to disable this feature. Example: # podman container checkpoint --export checkpoint.tar.gz <container> The content of all volumes associated with the container are included in `checkpoint.tar.gz` # podman container checkpoint --export checkpoint.tar.gz --ignore-volumes <container> The content of volumes is not included in `checkpoint.tar.gz`. This is useful, for example, when the checkpoint/restore is performed on the same machine. # podman container restore --import checkpoint.tar.gz The associated volumes will be created and their content will be restored. Podman will exit with an error if volumes with the same name already exist on the system or the content of volumes is not included in checkpoint.tar.gz # podman container restore --ignore-volumes --import checkpoint.tar.gz Volumes associated with container must already exist. Podman will not create them or restore their content. Signed-off-by: Radostin Stoyanov <rstoyanov@fedoraproject.org>
