* Add init containers to generate and play kubeUrvashi Mohnani2021-09-10
| | | | | | | | | | | | | | | Kubernetes has a concept of init containers that run and exit before the regular containers in a pod are started. We added init containers to podman pods as well. This patch adds support for generating init containers in the kube yaml when a pod we are converting had init containers. When playing a kube yaml, it detects an init container and creates such a container in podman accordingly. Note, only init containers created with the init type set to "always" will be generated as the "once" option deletes the init container after it has run and exited. Play kube will always creates init containers with the "always" init container type. Signed-off-by: Urvashi Mohnani <umohnani@redhat.com>

| * | container inspect: improve error handlingValentin Rothberg2021-09-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Improve the error handling of `container inspect` to properly handle when the container has been removed _between_ the lookup and the inspect. That will yield the correct "no such object" error message in `inspect`. [NO TESTS NEEDED] since I do not know have a reliable and cheap reproducer. It's fixing a CI flake, so there's already an indicator. Fixes: #11392 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

Usage `podman pod logs <podIDorName` gives a stream of logs for all the containers within the pod with **containername** as a field.

* podman stop always cleanupPaul Holzinger2021-09-01
| | | | | | | | | | | | | | | When a container is configured for auto removal podman stop should still do cleanup, there is no guarantee the the cleanup process spawned by conmon will be successful. Also a user expects after podman stop that the network/mounts are cleaned up. Therefore podman stop should not return early and instead do the cleanup and ignore errors if the container was already removed. [NO TESTS NEEDED] I don't know how to test this.

* 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>

* make sure that signal buffers are sufficiently bigValentin Rothberg2021-08-17
| | | | | | | | | | | | | | | Dealing with os.Signal channels seems more like an art than science since signals may get lost. os.Notify doesn't block on an unbuffered channel, so users are expected to know what they're doing or hope for the best. In the recent past, I've seen a number of flakes and BZs on non-amd64 architectures where I was under the impression that signals may got lost, for instance, during stop and exec.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | this is the first pass at implementing init containers for podman pods. init containersare made popular by k8s as a way to run setup for pods before the pods standard containers run. unlike k8s, we support two styles of init containers: always and oneshot. always means the container stays in the pod and starts whenever a pod is started. this does not apply to pods restarting. oneshot means the container runs onetime when the pod starts and then is removed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | podman stats polled by default in a 1 sec period. This can put quite some load on a machine if you run many containers.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There was an race condition when calling `GetRootlessCNINetNs()`. It created the rootless cni directory before it got locked. Therefore another process could have called cleanup and removed this directory before it was used resulting in errors. The lockfile got moved into the XDG_RUNTIME_DIR directory to prevent a panic when the parent dir was removed by cleanup. Fixes #10930 Fixes #10922 To make this even more robust `GetRootlessCNINetNs()` will now return locked. This guarantees that we can run `Do()` after `GetRootlessCNINetNs()` before another process could have called `Cleanup()` in between. [NO TESTS NEEDED] CI is flaking, hopefully this will fix it.

* auto-update: make output more user friendlyValentin Rothberg2021-07-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The rather raw and scarce output of `podman auto-update` has been a thorn in my eyes for a longer while. So far, Podman would only print updated systemd units, one per line, without further formatting. Motivated by issue #9949 which is asking for some more useful information in combination with a dry-run feature, I sat down and reflected which information may come in handy. Running `podman auto-update` will now look as follows: ``` $ podman auto-update Trying to pull [...] UNIT CONTAINER IMAGE POLICY UPDATED container-test.service 08fd34e533fd (test) localhost:5000/busybox registry false ``` Also refactor the spaghetti code in the backend a bit to make it easier to digest and maintain. For easier testing and for the sake of consistency with other commands listing output, add a `--format` flag. The man page will get an overhaul in a follow up commit.

This allows the user to specify a second image/container to compare the first with. If it is not set the parent layer will be used as before. Second, podman container diff should only use containers and podman image diff should only use images. Previously, podman container diff would use the image when both an image and container with this name exists. To make this work two new parameters have been added to the api. If they are not used the previous behaviour is used. The same applies to the bindings. Fixes #10649 Signed-off-by: Paul Holzinger <pholzing@redhat.com>
