| * Add ensureState helper for checking container stateMatthew Heon2019-10-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have a lot of checks for container state scattered throughout libpod. Many of these need to ensure the container is in one of a given set of states so an operation may safely proceed. Previously there was no set way of doing this, so we'd use unique boolean logic for each one. Introduce a helper to standardize state checks. Note that this is only intended to replace checks for multiple states. A simple check for one state (ContainerStateRunning, for example) should remain a straight equality, and not use this new helper. Signed-off-by: Matthew Heon <mheon@redhat.com>

|\ \ | |/ |/| Return a better error for volume name conflicts
| * Return a better error for volume name conflictsMatthew Heon2019-10-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When you try and create a new volume with the name of a volume that already exists, you presently get a thoroughly unhelpful error from `mkdir` as the volume attempts to create the directory it will be mounted at. An EEXIST out of mkdir is not particularly helpful to Podman users - it doesn't explain that the name is already taken by another volume. The solution here is potentially racy as the runtime is not locked, so someone else could take the name while we're still getting things set up, but that's a narrow timing window, and we will still return an error - just an error that's not as good as this one.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, when `podman run` encountered a volume mount without separate source and destination (e.g. `-v /run`) we would assume that both were the same - a bind mount of `/run` on the host to `/run` in the container. However, this does not match Docker's behavior - in Docker, this makes an anonymous named volume that will be mounted at `/run`. We already have (more limited) support for these anonymous volumes in the form of image volumes. Extend this support to allow it to be used with user-created volumes coming in from the `-v` flag. This change also affects how named volumes created by the container but given names are treated by `podman run --rm` and `podman rm -v`. Previously, they would be removed with the container in these cases, but this did not match Docker's behaviour. Docker only removed anonymous volumes. With this patch we move to that model as well; `podman run -v testvol:/test` will not have `testvol` survive the container being removed by `podman rm -v`. The sum total of these changes let us turn on volume removal in `--rm` by default. Fixes: #4276 Signed-off-by: Matthew Heon <matthew.heon@pm.me>

| * Add a MissingRuntime implementationMatthew Heon2019-10-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a container is created with a given OCI runtime, but then it is uninstalled or removed from the configuration file, Libpod presently reacts very poorly. The EvictContainer code can potentially remove these containers, but we still can't see them in `podman ps` (aside from the massive logrus.Errorf messages they create). Providing a minimal OCI runtime implementation for missing runtimes allows us to behave better. We'll be able to retrieve containers from the database, though we still pop up an error for each missing runtime. For containers which are stopped, we can remove them as normal.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Also, ensure that we don't try to mount them without root - it appears that it can somehow not error and report that mount was successful when it clearly did not succeed, which can induce this case. We reuse the `--force` flag to indicate that a volume should be removed even after unmount errors. It seems fairly natural to expect that --force will remove a volume that is otherwise presenting problems. Finally, ignore EINVAL on unmount - if the mount point no longer exists our job is done.

* | inspect: rename ImageID go field to ImageValentin Rothberg2019-10-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The json field is called `Image` while the go field is called `ImageID`, tricking users into filtering for `Image` which ultimately results in an error. Hence, rename the field to `Image` to align json and go. To prevent podman users from regressing, rename `Image` to `ImageID` in the specified filters. Add tests to prevent us from regressing. Note that consumers of the go API that are using `ImageID` are regressing; ultimately we consider it to be a bug fix. Fixes: #4193 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

|\ | | | | Move OCI runtime implementation behind an interface
| * When restoring containers, reset cgroup pathMatthew Heon2019-10-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, `podman checkport restore` with exported containers, when told to create a new container based on the exported checkpoint, would create a new container, with a new container ID, but not reset CGroup path - which contained the ID of the original container. If this was done multiple times, the result was two containers with the same cgroup paths. Operations on these containers would this have a chance of crossing over to affect the other one; the most notable was `podman rm` once it was changed to use the --all flag when stopping the container; all processes in the cgroup, including the ones in the other container, would be stopped. Reset cgroups on restore to ensure that the path matches the ID of the container actually being run. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
| * Move OCI runtime implementation behind an interfaceMatthew Heon2019-10-10
| | | | | | | | | | | | | | | | | | | | | | | | For future work, we need multiple implementations of the OCI runtime, not just a Conmon-wrapped runtime matching the runc CLI. As part of this, do some refactoring on the interface for exec (move to a struct, not a massive list of arguments). Also, add 'all' support to Kill and Stop (supported by runc and used a bit internally for removing containers). Signed-off-by: Matthew Heon <matthew.heon@pm.me>
