* 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: support --privilegedValentin Rothberg2021-02-09
| | | | | | | | | | | Do not play with capabilities for privileged containers where all capabilities will be set implicitly. Also, avoid the device check when running privileged since all of /dev/* will be mounted in any case. Fixes: #8897 Signed-off-by: Valentin Rothberg <rothberg@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.

* move go module to v2Valentin Rothberg2020-07-06
| | | | | | | | | | | | | | | With the advent of Podman 2.0.0 we crossed the magical barrier of go modules. While we were able to continue importing all packages inside of the project, the project could not be vendored anymore from the outside. Move the go module to new major version and change all imports to `github.com/containers/libpod/v2`. The renaming of the imports was done via `gomove` [1].

* 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | the compilation demands of having libpod in main is a burden for the remote client compilations. to combat this, we should move the use of libpod structs, vars, constants, and functions into the adapter code where it will only be compiled by the local client. this should result in cleaner code organization and smaller binaries. it should also help if we ever need to compile the remote client on non-Linux operating systems natively (not cross-compiled).

* | Only include ports in one container in Kube YAMLMatthew Heon2019-06-24
|/ | | | | | | | | | | | | This likely broke when we made containers able to detect that they shared a network namespace and grab ports from the dependency container - prior to that, we could grab ports without concern for conflict, only the infra container had them.

| | | | | | | | | | All IDs in libpod are stored as a full container ID.
