* faster image inspectionValentin Rothberg2021-10-08
| | | | | | | | | | | | | | Vendor the latest HEAD in c/common to pull in changes for a faster inspection of images. Previously, only the size computation was optional, now the one for the parent image is as well. In many cases, the parent image is not needed but it takes around 10ms on my local machine. With this change, we cut off 10ms from many code paths, most importantly, container creation. [NO NEW TESTS NEEDED] Signed-off-by: Valentin Rothberg <rothberg@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>

* podman generate kube should not include images commandDaniel J Walsh2021-09-22
| | | | | | | | | If the command came from the underlying image, then we should not include it in the generate yaml file. Fixes: https://github.com/containers/podman/issues/11672 Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
* Generate kube should'd add podman default environment varsDaniel J Walsh2021-09-21
| | | | | | | | Currently we add the default PATH, TERM and container from Podman to every kubernetes.yaml file. These values should not be recorded in the yaml files. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
* Drop OCICNI dependencyPaul Holzinger2021-09-15
| | | | | | | | | | | We do not use the ocicni code anymore so let's get rid of it. Only the port struct is used but we can copy this into libpod network types so we can debloat the binary. The next step is to remove the OCICNI port mapping form the container config and use the better PortMapping struct everywhere. Signed-off-by: Paul Holzinger <pholzing@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>

* Generate Kubernetes PersistentVolumeClaims from named volumesJordan Williams2021-03-19
| | | | | | | | | | | | Fixes #5788 This commit adds support for named volumes in podman-generate-kube. Named volumes are output in the YAML as PersistentVolumeClaims. To avoid naming conflicts, the volume name is suffixed with "-pvc". This commit adds a corresponding suffix for host path mounts. Host path volumes are suffixed with "-host".

* 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>
* Allow users to generate a kubernetes yaml off non running containersDaniel J Walsh2021-03-08
| | | | | | | | | | | | | | | Currently if you attempt to create a kube.yaml file off of a non running container where the container runs as a specific User, the creation fails because the storage container is not mounted. Podman is supposed to read the /etc/passwd entry inside of the container but since the container is not mounted, the c.State.Mountpoint == "". Podman incorrectly attempts to read /etc/passwd on the host, and fails if the specified user is not in the hosts /etc/passwd. This PR mounts the storage container, if it was not mounted so the read succeeds. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>

* generate kube: handle entrypointValentin Rothberg2021-02-04
| | | | | | | | | | The spec of a Kube Container has a `Command` and `Args`. While both are slices, the `Command` is the counterpart of the entrypoint of a libpod container. Kube is also happily accepting the arguments to as following items in the slice but it's cleaner to move those to `Args`. Fixes: #9211 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

* Honor custom DNS in play|generate kubebaude2021-01-29
| | | | | | | | | | | | | | | | | | when creating kubernetes yaml from containers and pods, we should honor any custom dns settings the user provided. in the case of generate kube, these would be provided by --dns, --dns-search, and --dns-opt. if multiple containers are involved in the generate, the options will be cumulative and unique with the exception of dns-opt. when replaying a kube file that has kubernetes dns information, we now also add that information to the pod creation. the options for dnspolicy is not enabled as there seemed to be no direct correlation between kubernetes and podman.

| | | | | | | | | | | | | | | With the advent of Podman 2.0.0 we crossed the magical barrier of go modules.

* add {generate,play} kubeValentin Rothberg2020-05-06
| | | | | | | | | | | | | | | | | | | Add the `podman generate kube` and `podman play kube` command. The code has largely been copied from Podman v1 but restructured to not leak the K8s core API into the (remote) client. Both commands are added in the same commit to allow for enabling the tests at the same time. Move some exports from `cmd/podman/common` to the appropriate places in the backend to avoid circular dependencies. Move definitions of label annotations to `libpod/define` and set the security-opt labels in the frontend to make kube tests pass. Implement rest endpoints, bindings and the tunnel interface.
