* libpod: fix wait and exit-code logicValentin Rothberg2022-06-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit addresses three intertwined bugs to fix an issue when using Gitlab runner on Podman. The three bug fixes are not split into separate commits as tests won't pass otherwise; avoidable noise when bisecting future issues. 1) Podman conflated states: even when asking to wait for the `exited` state, Podman returned as soon as a container transitioned to `stopped`. The issues surfaced in Gitlab tests to fail [1] as `conmon`'s buffers have not (yet) been emptied when attaching to a container right after a wait. The race window was extremely narrow, and I only managed to reproduce with the Gitlab runner [1] unit tests. 2) The clearer separation between `exited` and `stopped` revealed a race condition predating the changes. If a container is configured for autoremoval (e.g., via `run --rm`), the "run" process competes with the "cleanup" process running in the background. The window of the race condition was sufficiently large that the "cleanup" process has already removed the container and storage before the "run" process could read the exit code and hence waited indefinitely. Address the exit-code race condition by recording exit codes in the main libpod database. Exit codes can now be read from a database. When waiting for a container to exit, Podman first waits for the container to transition to `exited` and will then query the database for its exit code. Outdated exit codes are pruned during cleanup (i.e., non-performance critical) and when refreshing the database after a reboot. An exit code is considered outdated when it is older than 5 minutes. While the race condition predates this change, the waiting process has apparently always been fast enough in catching the exit code due to issue 1): `exited` and `stopped` were conflated. The waiting process hence caught the exit code after the container transitioned to `stopped` but before it `exited` and got removed. 3) With 1) and 2), Podman is now waiting for a container to properly transition to the `exited` state. Some tests did not pass after 1) and 2) which revealed the third bug: `conmon` was executed with its working directory pointing to the OCI runtime bundle of the container. The changed working directory broke resolving relative paths in the "cleanup" process. The "cleanup" process error'ed before actually cleaning up the container and waiting "main" process ran indefinitely - or until hitting a timeout. Fix the issue by executing `conmon` with the same working directory as Podman. Note that fixing 3) *may* address a number of issues we have seen in the past where for *some* reason cleanup processes did not fire.

* k8systemd: run k8s workloads in systemdValentin Rothberg2022-05-17
| | | | | | | | | | | | | | | | | | | | Support running `podman play kube` in systemd by exploiting the previously added "service containers". During `play kube`, a service container is started before all the pods and containers, and is stopped last. The service container communicates its conmon PID via sdnotify. Add a new systemd template to dispatch such k8s workloads. The argument of the template is the path to the k8s file. Note that the path must be escaped for systemd not to bark: Let's assume we have a `top.yaml` file in the home directory: ``` $ escaped=$(systemd-escape ~/top.yaml) $ systemctl --user start podman-play-kube@$escaped.service ``` Closes: https://issues.redhat.com/browse/RUN-1287 Signed-off-by: Valentin Rothberg <vrothberg@redhat.com>

* | Add support for checkpoint imageRadostin Stoyanov2022-04-20
|/ | | | | | | | | | | | | | | | | | | | | | | | This is an enhancement proposal for the checkpoint / restore feature of Podman that enables container migration across multiple systems with standard image distribution infrastructure. A new option `--create-image <image>` has been added to the `podman container checkpoint` command. This option tells Podman to create a container image. This is a standard image with a single layer, tar archive, that that contains all checkpoint files. This is similar to the current approach with checkpoint `--export`/`--import`. This image can be pushed to a container registry and pulled on a different system. It can also be exported locally with `podman image save` and inspected with `podman inspect`. Inspecting the image would display additional information about the host and the versions of Podman, criu, crun/runc, kernel, etc. `podman container restore` has also been extended to support image name or ID as input.

* podman stats: calc CPU percentage correctlyPaul Holzinger2022-03-22
| | | | | | | | | | | | | | | | | | | | | When you run podman stats, the first interval always shows the wrong cpu usage. To calculate cpu percentage we get the cpu time from the cgroup and compare this against the system time between two stats. Since the first time we do not have a previous stats an empty struct is used instead. Thus we do not use the actual running time of the container but the current unix timestamp (time since Jan 1 1970). To fix this we make sure that the previous stats time is set to the container start time, when it is empty. [NO NEW TESTS NEEDED] No idea how I could create a test which would have a predictable cpu usage. See the linked bugzilla for a reproducer.

| * Do not store the exit command in container configPaul Holzinger2021-11-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a problem with creating and storing the exit command when the container was created. It only contains the options the container was created with but NOT the options the container is started with. One example would be a CNI network config. If I start a container once, then change the cni config dir with `--cni-config-dir` ans start it a second time it will start successfully. However the exit command still contains the wrong `--cni-config-dir` because it was not updated. To fix this we do not want to store the exit command at all. Instead we create it every time the conmon process for the container is startet. This guarantees us that the container cleanup process is startet with the correct settings.

| | | | | | | | | | | | | | | | | | There's a potential race around extremely short-running containers and events with journald.

* | Support checkpoint/restore with podsAdrian Reber2021-07-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support to checkpoint containers out of pods and restore container into pods. It is only possible to restore a container into a pod if it has been checkpointed out of pod. It is also not possible to restore a non pod container into a pod. The main reason this does not work is the PID namespace. If a non pod container is being restored in a pod with a shared PID namespace, at least one process in the restored container uses PID 1 which is already in use by the infrastructure container. If someone tries to restore container from a pod with a shared PID namespace without a shared PID namespace it will also fail because the resulting PID namespace will not have a PID 1.
