| * 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>
* | Make errors on removing exec sessions nonfatalMatthew Heon2022-05-16
|/ | | | | | | | | | | | | | | | | Removing exec sessions is guaranteed to evict them from the DB, but in the case of a zombie process (or similar) it may error and block removal of the container. A subsequent run of `podman rm` would succeed (because the exec sessions have been purged from the DB), which is potentially confusing to users. So let's just continue, instead of erroring out, if removing exec sessions fails. [NO NEW TESTS NEEDED] I wouldn't want to spawn a zombie in our test VMs even if I could.

| | | | | | | | | | | | | | | | | | | | | | When removing a container created with a --volumes-from a container created with a built in volume, we complain if the original container still exists.

* | Remove the runtime lockMatthew Heon2022-02-22
|/ | | | | | | | | | | | | | | | This primarily served to protect us against shutting down the Libpod runtime while operations (like creating a container) were happening. However, it was very inconsistently implemented (a lot of our longer-lived functions, like pulling images, just didn't implement it at all...) and I'm not sure how much we really care about this very-specific error case? Removing it also removes a lot of potential deadlocks, which is nice. [NO NEW TESTS NEEDED] Signed-off-by: Matthew Heon <mheon@redhat.com>

* 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.

* | move network alias validation to container createPaul Holzinger2021-09-28
|/ | | | | | | | | | Podman 4.0 currently errors when you use network aliases for a network which has dns disabled. Because the error happens on network setup this can cause regression for old working containers. The network backend should not validate this.

* Wire network interface into libpodPaul Holzinger2021-09-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make use of the new network interface in libpod. This commit contains several breaking changes: - podman network create only outputs the new network name and not file path. - podman network ls shows the network driver instead of the cni version and plugins. - podman network inspect outputs the new network struct and not the cni conflist. - The bindings and libpod api endpoints have been changed to use the new network structure. The container network status is stored in a new field in the state. The status should be received with the new `c.getNetworkStatus`. This will migrate the old status to the new format. Therefore old containers should contine to work correctly in all cases even when network connect/ disconnect is used. New features: - podman network reload keeps the ip and mac for more than one network. - podman container restore keeps the ip and mac for more than one network. - The network create compat endpoint can now use more than one ipam config. The man pages and the swagger doc are updated to reflect the latest changes. Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* InfraContainer Reworkcdoern2021-08-26
| | | | | | | | | | InfraContainer should go through the same creation process as regular containers. This change was from the cmd level down, involving new container CLI opts and specgen creating functions. What now happens is that both container and pod cli options are populated in cmd and used to create a podSpecgen and a containerSpecgen. The process then goes as follows FillOutSpecGen (infra) -> MapSpec (podOpts -> infraOpts) -> PodCreate -> MakePod -> createPodOptions -> NewPod -> CompleteSpec (infra) -> MakeContainer -> NewContainer -> newContainer -> AddInfra (to pod state) Signed-off-by: cdoern <cdoern@redhat.com>

| | | | | | | | | | | | When a network id is used to create a container we translate it to use the name internally for the db.

* Ensure that container still exists when removingMatthew Heon2021-05-26
| | | | | | | | | | | | | | | | | | After #8906, there is a potential race condition in container removal of running containers with `--rm`. Running containers must first be stopped, which was changed to unlock the container to allow commands like `podman ps` to continue to run while stopping; however, this also means that the cleanup process can potentially run before we re-lock, and remove the container from under us, resulting in error messages from `podman rm`. The end result is unchanged, the container is still cleanly removed, but the `podman rm` command will seem to have failed. Work around this by pinging the database after we stop the container to make sure it still exists. If it doesn't, our job is done and we can exit cleanly.

| | | | | | | | | | | | | | | | | | 10 lines above we had // Set ContainerStateRemoving c.state.State = define.ContainerStateRemoving Which causes the state to not be the two checked states.
