| | | | | | | | | | We should not be fuzzy matching on volume names. Docker doesn't do it, and it doesn't make much sense. Everything requires exact matches for names - only IDs allow partial matches. Fixes #3635 Signed-off-by: Matthew Heon <matthew.heon@pm.me>

| * Fix a segfault on Podman no-store commands with refreshMatthew Heon2019-07-23
| | | | | | | | | | | | | | | | | | | | | | | | | | When a command (like `ps`) requests no store be created, but also requires a refresh be performed, we have to ignore its request and initialize the store anyways to prevent segfaults. This work was done in #3532, but that missed one thing - initializing a storage service. Without the storage service, Podman will still segfault. Fix that oversight here.

|\ | | | | Include changes to the container's root file-system in the checkpoint archive
| * Add --ignore-rootfs option for checkpoint/restoreAdrian Reber2019-07-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The newly added functionality to include the container's root file-system changes into the checkpoint archive can now be explicitly disabled. Either during checkpoint or during restore. If a container changes a lot of files during its runtime it might be more effective to migrated the root file-system changes in some other way and to not needlessly increase the size of the checkpoint archive. If a checkpoint archive does not contain the root file-system changes information it will automatically be skipped. If the root file-system changes are part of the checkpoint archive it is also possible to tell Podman to ignore these changes. Signed-off-by: Adrian Reber <areber@redhat.com>

| * Include root file-system changes in container migrationAdrian Reber2019-07-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | One of the last limitations when migrating a container using Podman's 'podman container checkpoint --export=/path/to/archive.tar.gz' was that it was necessary to manually handle changes to the container's root file-system. The recommendation was to mount everything as --tmpfs where the root file-system was changed. This extends the checkpoint export functionality to also include all changes to the root file-system in the checkpoint archive. The checkpoint archive now includes a tarstream of the result from 'podman diff'. This tarstream will be applied to the restored container before restoring the container. With this any container can now be migrated, even it there are changes to the root file-system. There was some discussion before implementing this to base the root file-system migration on 'podman commit', but it seemed wrong to do a 'podman commit' before the migration as that would change the parent layer the restored container is referencing. Probably not really a problem, but it would have meant that a migrated container will always reference another storage top layer than it used to reference during initial creation.

| * Add function to get a filtered tarstream diffAdrian Reber2019-07-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The newly added function GetDiffTarStream() mirrors the GetDiff() function. It tries to get the correct layer ID from getLayerID() and it filters out containerMounts from the tarstream. Thus the behavior is the same as GetDiff(), but it returns a tarstream. This also adds the function ApplyDiffTarStream() to apply the tarstream generated by GetDiffTarStream(). These functions are targeted to support container migration with root file-system changes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Our previous method (just read the PID that we spawned) doesn't work - Conmon double-forks to daemonize, so we end up with a PID pointing to the first process, which dies almost immediately.

* | | Move the HostConfig portion of Inspect inside libpodMatthew Heon2019-07-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we first began writing Podman, we ran into a major issue when implementing Inspect. Libpod deliberately does not tie its internal data structures to Docker, and stores most information about containers encoded within the OCI spec. However, Podman must present a CLI compatible with Docker, which means it must expose all the information in 'docker inspect' - most of which is not contained in the OCI spec or libpod's Config struct. Our solution at the time was the create artifact. We JSON'd the complete CreateConfig (a parsed form of the CLI arguments to 'podman run') and stored it with the container, restoring it when we needed to run commands that required the extra info. Over the past month, I've been looking more at Inspect, and refactored large portions of it into Libpod - generating them from what we know about the OCI config and libpod's (now much expanded, versus previously) container configuration. This path comes close to completing the process, moving the last part of inspect into libpod and removing the need for the create artifact. This improves libpod's compatability with non-Podman containers. We no longer require an arbitrarily-formatted JSON blob to be present to run inspect.
