* Add --requires flag to podman run/createMatthew Heon2021-04-06
| | | | | | | | | | | | | | | | | | | | Podman has, for a long time, had an internal concept of dependency management, used mainly to ensure that pod infra containers are started before any other container in the pod. We also have the ability to recursively start these dependencies, which we use to ensure that `podman start` on a container in a pod will not fail because the infra container is stopped. We have not, however, exposed these via the command line until now. Add a `--requires` flag to `podman run` and `podman create` to allow users to manually specify dependency containers. These containers must be running before the container will start. Also, make recursive starting with `podman start` default so we can start these containers and their dependencies easily.

* Do not leak libpod package into the remote clientPaul Holzinger2021-03-15
| | | | | | | | | | | | | | | | | | Some packages used by the remote client imported the libpod package. This is not wanted because it adds unnecessary bloat to the client and also causes problems with platform specific code(linux only), see #9710. The solution is to move the used functions/variables into extra packages which do not import libpod. This change shrinks the remote client size more than 6MB compared to the current master. [NO TESTS NEEDED] I have no idea how to test this properly but with #9710 the cross compile should fail. Signed-off-by: Paul Holzinger <paul.holzinger@web.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Traditionally, the path resolution for containers has been resolved on the *host*; relative to the container's mount point or relative to specified bind mounts or volumes. While this works nicely for non-running containers, it poses a problem for running ones. In that case, certain kinds of mounts (e.g., tmpfs) will not resolve correctly. A tmpfs is held in memory and hence cannot be resolved relatively to the container's mount point. A copy operation will succeed but the data will not show up inside the container. To support these kinds of mounts, we need to join the *running* container's mount namespace (and PID namespace) when copying. Note that this change implies moving the copy and stat logic into `libpod` since we need to keep the container locked to avoid race conditions. The immediate benefit is that all logic is now inside `libpod`; the code isn't scattered anymore. Further note that Docker does not support copying to tmpfs mounts. Tests have been extended to cover *both* path resolutions for running and created containers. New tests have been added to exercise the tmpfs-mount case. For the record: Some tests could be improved by using `start -a` instead of a start-exec sequence. Unfortunately, `start -a` is flaky in the CI which forced me to use the more expensive start-exec option. Signed-off-by: Valentin Rothberg <rothberg@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>

| * container stop: release lock before calling the runtimeValentin Rothberg2021-01-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Podman defers stopping the container to the runtime, which can take some time. Keeping the lock while waiting for the runtime to complete the stop procedure, prevents other commands from acquiring the lock as shown in #8501. To improve the user experience, release the lock before invoking the runtime, and re-acquire the lock when the runtime is finished. Also introduce an intermediate "stopping" to properly distinguish from "stopped" containers etc. Fixes: #8501 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

* / Expose security attribute errors with their own messagesJuan Antonio Osorio Robles2021-01-12
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This creates error objects for runtime errors that might come from the runtime. Thus, indicating to users that the place to debug should be in the security attributes of the container. When creating a container with a SELinux label that doesn't exist, we get a fairly cryptic error message: ``` $ podman run --security-opt label=type:my_container.process -it fedora bash Error: OCI runtime error: write file `/proc/thread-self/attr/exec`: Invalid argument ``` This instead handles any errors coming from LSM's `/proc` API and enhances the error message with a relevant indicator that it's related to the container's security attributes. A sample run looks as follows: ``` $ bin/podman run --security-opt label=type:my_container.process -it fedora bash Error: `/proc/thread-self/attr/exec`: OCI runtime error: unable to assign security attribute ``` With `debug` log level enabled it would be: ``` Error: write file `/proc/thread-self/attr/exec`: Invalid argument: OCI runtime error: unable to assign security attribute ``` Note that these errors wrap ErrOCIRuntime, so it's still possible to to compare these errors with `errors.Is/errors.As`. One advantage of this approach is that we could start handling these errors in a more efficient manner in the future. e.g. If a SELinux label doesn't exist (yet), we could retry until it becomes available.

* Add support for network connect / disconnect to DBMatthew Heon2020-11-11
| | | | | | | | | | | | | | | | | | | | | | | | Convert the existing network aliases set/remove code to network connect and disconnect. We can no longer modify aliases for an existing network, but we can add and remove entire networks. As part of this, we need to add a new function to retrieve current aliases the container is connected to (we had a table for this as of the first aliases PR, but it was not externally exposed). At the same time, remove all deconflicting logic for aliases. Docker does absolutely no checks of this nature, and allows two containers to have the same aliases, aliases that conflict with container names, etc - it's just left to DNS to return all the IP addresses, and presumably we round-robin from there? Most tests for the existing code had to be removed because of this. Convert all uses of the old container config.Networks field, which previously included all networks in the container, to use the new DB table. This ensures we actually get an up-to-date list of in-use networks. Also, add network aliases to the output of `podman inspect`. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the database backend for network aliases. Aliases are additional names for a container that are used with the CNI dnsname plugin - the container will be accessible by these names in addition to its name. Aliases are allowed to change over time as the container connects to and disconnects from networks. Aliases are implemented as another bucket in the database to register all aliases, plus two buckets for each container (one to hold connected CNI networks, a second to hold its aliases). The aliases are only unique per-network, to the global and per-container aliases buckets have a sub-bucket for each CNI network that has aliases, and the aliases are stored within that sub-bucket. Aliases are formatted as alias (key) to container ID (value) in both cases. Three DB functions are defined for aliases: retrieving current aliases for a given network, setting aliases for a given network, and removing all aliases for a given network.

* Store cgroup manager on a per-container basisMatthew Heon2020-10-08
| | | | | | | | | | | | | | | | | | | | | When we create a container, we assign a cgroup parent based on the current cgroup manager in use. This parent is only usable with the cgroup manager the container is created with, so if the default cgroup manager is later changed or overridden, the container will not be able to start. To solve this, store the cgroup manager that created the container in container configuration, so we can guarantee a container with a systemd cgroup parent will always be started with systemd cgroups. Unfortunately, this is very difficult to test in CI, due to the fact that we hard-code cgroup manager on all invocations of Podman in CI. Fixes #7830 Signed-off-by: Matthew Heon <matthew.heon@pm.me>
