* Add support for containers.conf volume timeoutsMatthew Heon2022-08-23
| | | | | | | | | | | | | | | | | | | | | | | | Also, do a general cleanup of all the timeout code. Changes include: - Convert from int to *uint where possible. Timeouts cannot be negative, hence the uint change; and a timeout of 0 is valid, so we need a new way to detect that the user set a timeout (hence, pointer). - Change name in the database to avoid conflicts between new data type and old one. This will cause timeouts set with 4.2.0 to be lost, but considering nobody is using the feature at present (and the lack of validation means we could have invalid, negative timeouts in the DB) this feels safe. - Ensure volume plugin timeouts can only be used with volumes created using a plugin. Timeouts on the local driver are nonsensical. - Remove the existing test, as it did not use a volume plugin. Write a new test that does. The actual plumbing of the containers.conf timeout in is one line in volume_api.go; the remainder are the above-described cleanups. Signed-off-by: Matthew Heon <mheon@redhat.com>

* | add podman volume reload to sync volume pluginsPaul Holzinger2022-06-23
|/ | | | | | | | | | | | | | | | | | | Libpod requires that all volumes are stored in the libpod db. Because volume plugins can be created outside of podman, it will not show all available plugins. This podman volume reload command allows users to sync the libpod db with their external volume plugins. All new volumes from the plugin are also created in the libpod db and when a volume from the db no longer exists it will be removed if possible. There are some problems: - naming conflicts, in this case we only use the first volume we found. This is not deterministic. - race conditions, we have no control over the volume plugins. It is possible that the volumes changed while we run this command. Fixes #14207 Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* Set volume NeedsCopyUp to false iff data was copied upDaniel J Walsh2022-01-06
| | | | | | | | | | | | Currently Docker copies up the first volume on a mountpoint with data. Fixes: https://github.com/containers/podman/issues/12714 Also added NeedsCopyUP, NeedsChown and MountCount to the podman volume inspect code. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
* Initial implementation of volume pluginsMatthew Heon2021-01-14
This implements support for mounting and unmounting volumes backed by volume plugins. Support for actually retrieving plugins requires a pull request to land in containers.conf and then that to be vendored, and as such is not yet ready. Given this, this code is only compile tested. However, the code for everything past retrieving the plugin has been written - there is support for creating, removing, mounting, and unmounting volumes, which should allow full functionality once the c/common PR is merged. A major change is the signature of the MountPoint function for volumes, which now, by necessity, returns an error. Named volumes managed by a plugin do not have a mountpoint we control; instead, it is managed entirely by the plugin. As such, we need to cache the path in the DB, and calls to retrieve it now need to access the DB (and may fail as such). Notably absent is support for SELinux relabelling and chowning these volumes. Given that we don't manage the mountpoint for these volumes, I am extremely reluctant to try and modify it - we could easily break the plugin trying to chown or relabel it. Also, we had no less than *5* separate implementations of inspecting a volume floating around in pkg/infra/abi and pkg/api/handlers/libpod. And none of them used volume.Inspect(), the only correct way of inspecting volumes. Remove them all and consolidate to using the correct way. Compat API is likely still doing things the wrong way, but that is an issue for another day. Fixes #4304 Signed-off-by: Matthew Heon <matthew.heon@pm.me>
