* implement init containers in podmanBrent Baude2021-08-04
| | | | | | | | | | | | | | 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.

* vendor containers/common@mainValentin Rothberg2021-07-16
| | | | | | | | | | | | | The `IgnorePlatform` options has been removed from the `LookupImageOptions` in libimage to properly support multi-arch images. Skip one buildah-bud test which requires updated CI images. This is currently being done in github.com/containers/podman/pull/10829 but we need to unblock merging common and buildah into podman.

* | create: support images with invalid platformValentin Rothberg2021-06-23
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Much to my regret, there is a number of images in the wild with invalid platforms breaking the platform checks in libimage that want to make sure that a local image is matching the expected platform. Imagine a `podman run --arch=arm64 fedora` with a local amd64 fedora image. We really shouldn't use the local one in this case and pull down the arm64 one. The strict platform checks in libimage in combination with invalid platforms in images surfaced in Podman being able to pull an image but failing to look it up in subsequent presence checks. A `podman run` would hence pull such an image but fail to create the container. Support images with invalid platforms by vendoring the latest HEAD from containers/common. Also remove the partially implemented pull-policy logic from Podman and let libimage handle that entirely. However, whenever --arch, --os or --platform are specified, the pull policy will be forced to "newer". This way, we pessimistically assume that the local image has an invalid platform and we reach out to the registry. If there's a newer image (i.e., one with a different digest), we'll pull it down. Please note that most of the logic has either already been implemented in libimage or been moved down which allows for removing some clutter from Podman. [NO TESTS NEEDED] since c/common has new tests. Podman can rely on the existing tests. Fixes: #10648 Fixes: #10682 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* 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>

* workdir presence checksValentin Rothberg2021-01-26
| | | | | | | | | | | | | | | | | | A container's workdir can be specified via the CLI via `--workdir` and via an image config with the CLI having precedence. Since images have a tendency to specify workdirs without necessarily shipping the paths with the root FS, make sure that Podman creates the workdir. When specified via the CLI, do not create the path, but check for its existence and return a human-friendly error. NOTE: `crun` is performing a similar check that would yield exit code 127. With this change, however, Podman performs the check and yields exit code 126. Since this is specific to `crun`, I do not consider it to be a breaking change of Podman.

* Set log driver for compatability containersbaude2021-01-20
| | | | | | | | | | | | | | | when using the compatibility api to create containers, now reflect the use of k8s-file as json-file so that clients, which are unaware of k8s-file, can work. specifically, if the container is using k8s-file as the log driver, we change the log type in container inspection to json-file. These terms are used interchangably in other locations in libpod/podman. this fixes log messages in compose as well. [NO TESTS NEEDED] Signed-off-by: baude <bbaude@redhat.com>

* Ensure that --net=host/pod/container/none warn with -pMatthew Heon2020-11-04
| | | | | | | | | | | | Setting port mappings only works when CNI is configuring our network (or slirp4netns, in the rootless case). This is not the case with `--net=host`, `--net=container:`, and joining the network namespace of the pod we are part of. Instead of allowing users to do these things and then be confused why they do nothing, let's match Docker and return a warning that your port mappings will do nothing.

| | | | | | | | | | | | | | | | | | | | | Buildah and podman build can create images without a working dir. FROM fedora WORKDIR /test If you build this image with caching twice, the second time the image will not have a working dir. Similarly if you execute podman run --workdir /foobar fedora It blows up since the workingdir is not created automatically. Finally there was duplicated code for getting the workingdir out of an image, that this PR removes. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>

* 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].

* Re-add resource limit warnings to SpecgenMatthew Heon2020-06-16
| | | | | | | | | | | | | | | | | | | | | | These were part of Podman v1.9, but were lost in the transition to using Specgen to create containers. Most resource limits are checked via the sysinfo package to ensure they are safe to use (the cgroup is mounted, kernel support is present, etc) and removed if not safe. Further, bounds checks are performed to ensure that values are valid. Ensure these warnings are printed client-side when they occur. This part is a little bit gross, as it happens in pkg/infra and not cmd/podman, which is largely down to how we implemented `podman run` - all the work is done in pkg/infra and it returns only once the container has exited, and we need warnings to print *before* the container runs. The solution here, while inelegant, avoid the need to extensively refactor our handling of run. Should fix blkio-limit warnings that were identified by the FCOS test suite.

* Improve Entrypoint and Command supportMatthew Heon2020-04-27
| | | | | | | | | | | | | We should not be overwriting the Specgen's Command and Entrypoint when building the final command to pass in the OCI spec. Both of these will be provided to Libpod for use in `podman inspect` and committing containers, and both must be set to the user's input, not overwritten by the image if unset.
