* Fix CPU usage limitation in play kube for non integer valuesMikhail Khachayants2022-09-10
| | | | | | | | | | This logic has been broken by commit 9c6c981928c3e020ff6eef9454c7ee86aa8c83d1 (kube: fix conversion from milliCPU to period/quota). [NO NEW TESTS NEEDED] Fixes: #15726 Signed-off-by: Mikhail Khachayants <tyler92@inbox.ru>
* kube play: support auto updates and rollbacksValentin Rothberg2022-09-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add auto-update support to `podman kube play`. Auto-update policies can be configured for: * the entire pod via the `io.containers.autoupdate` annotation * a specific container via the `io.containers.autoupdate/$name` annotation To make use of rollbacks, the `io.containers.sdnotify` policy should be set to `container` such that the workload running _inside_ the container can send the READY message via the NOTIFY_SOCKET once ready. For further details on auto updates and rollbacks, please refer to the specific article [1]. Since auto updates and rollbacks bases on Podman's systemd integration, the k8s YAML must be executed in the `podman-kube@` systemd template. For further details on how to run k8s YAML in systemd via Podman, please refer to the specific article [2]. An examplary k8s YAML may look as follows: ```YAML apiVersion: v1 kind: Pod metadata: annotations: io.containers.autoupdate: "local" io.containers.autoupdate/b: "registry" labels: app: test name: test_pod spec: containers: - command: - top image: alpine name: a - command: - top image: alpine name: b ``` [1] https://www.redhat.com/sysadmin/podman-auto-updates-rollbacks [2] https://www.redhat.com/sysadmin/kubernetes-workloads-podman-systemd Signed-off-by: Valentin Rothberg <vrothberg@redhat.com>
* Fix bind-mount-option annotation in gen/play kubeUrvashi Mohnani2022-09-01

* Add emptyDir volume support to kube playUrvashi Mohnani2022-08-30
| | | | | | | | | | | When a kube yaml has a volume set as empty dir, podman will create an anonymous volume with the empty dir name and attach it to the containers running in the pod. When the pod is removed, the empy dir volume created is also removed. Add tests and docs for this as well. Signed-off-by: Urvashi Mohnani <umohnani@redhat.com>
* kube secret handling for podman play kubecdoern2022-07-20
| | | | | | | | | | | add support for both creating a secret using yaml and mounting a secret as a volume given a yaml file. Kubernetes secrets have a different structure than podman and therefore have to be handeled differently.

* enable gocritic linterPaul Holzinger2022-04-26
| | | | | | | | | | | | | | | | | | | | | | The linter ensures a common code style. - use switch/case instead of else if - use if instead of switch/case for single case statement - add space between comment and text - detect the use of defer with os.Exit() - use short form var += "..." instead of var = var + "..." - detect problems with append() ``` newSlice := append(orgSlice, val) ``` This could lead to nasty bugs because the orgSlice will be changed in place if it has enough capacity too hold the new elements. Thus we newSlice might not be a copy. Of course most of the changes are just cosmetic and do not cause any logic errors but I think it is a good idea to enforce a common style. This should help maintainability. Signed-off-by: Paul Holzinger <pholzing@redhat.com>

* | Support selinux options with bind mounts play/genBrent Baude2021-09-30
|/ | | | | | | | | | | | When using play kube and generate kube, we need to support if bind mounts have selinux options. As kubernetes does not support selinux in this way, we tuck the selinux values into a pod annotation for generation of the kube yaml. Then on play, we check annotations to see if a value for the mount exists and apply it. Fixes BZ #1984081 Signed-off-by: Brent Baude <bbaude@redhat.com>
* 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>
* 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>
* Network interfacePaul Holzinger2021-08-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement a new network interface to abstract CNI from libpod. The interface is implemented for the CNI backend but in the future we can add more backends. The code is structured in three new packages: - `libpod/network/types`: contains the interface definition and the necessary types for it. - `libpod/network/cni` contains the interface implementation for the CNI backend. - `libpod/network/util` a set of utility functions related to networking. The CNI package uses ginkgo style unit tests. To test Setup/Teardown the test must be run as root. Each test will run in their own namespace to make the test independent from the host environment. New features with the CNI backend: - The default network will be created in memory if it does not exists on disk. - It can set more than one static IP per container network. - Networks are loaded once from disk and only if this interface is used, e.g. for commands such as `podman info` networks are not loaded. This reduces unnecessary disk IO. This commit only adds the interface it is not wired into libpod. This requires a lot of breaking changes which will be done in a followup commit. Once this is integrated into libpod the current network code under `libpod/network` should be removed. Also the dependency on OCICNI should be dropped.

* migrate Podman to containers/common/libimageValentin Rothberg2021-05-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Migrate the Podman code base over to `common/libimage` which replaces `libpod/image` and a lot of glue code entirely. Note that I tried to leave bread crumbs for changed tests. Miscellaneous changes: * Some errors yield different messages which required to alter some tests. * I fixed some pre-existing issues in the code. Others were marked as `//TODO`s to prevent the PR from exploding. * The `NamesHistory` of an image is returned as is from the storage. Previously, we did some filtering which I think is undesirable. Instead we should return the data as stored in the storage. * Touched handlers use the ABI interfaces where possible. * Local image resolution: previously Podman would match "foo" on "myfoo". This behaviour has been changed and Podman will now only match on repository boundaries such that "foo" would match "my/foo" but not "myfoo". I consider the old behaviour to be a bug, at the very least an exotic corner case. * Futhermore, "foo:none" does *not* resolve to a local image "foo" without tag anymore. It's a hill I am (almost) willing to die on. * `image prune` prints the IDs of pruned images. Previously, in some cases, the names were printed instead. The API clearly states ID, so we should stick to it. * Compat endpoint image removal with _force_ deletes the entire not only the specified tag. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
