Pattern-rule documentation is in [1]. This commit follows the basic
approach from [2], with the portable build tags from [3].
Using --keep-going allows folks to see errors for multiple target
platforms. For example, if the Darwin target dies, we'll still
attempt to build the Linux target before erroring out.
I've added an ALLOWED_TO_FAIL environment variable to mark script
blocks for the the allow_failures block. Currently we're requiring
builds from Linux for Linux and OS X to succeed, but allowing builds
from OS X to both targets to fail.

libpod - library for running OCI-based containers in Pods
Status: Active Development
What is the scope of this project?
libpod provides a library for applications looking to use the Container Pod concept popularized by Kubernetes. libpod also contains a tool called podman for managing Pods, Containers, and Container Images.
At a high level, the scope of libpod and podman is the following:
- Support multiple image formats including the existing Docker/OCI image formats.
- Support for multiple means to download images including trust & image verification.
- Container image management (managing image layers, overlay filesystems, etc).
- Full management of container lifecycle
- Support for pods to manage groups of containers together
- Resource isolation of containers and pods.
What is not in scope for this project?
- Signing and pushing images to various image storages. See Skopeo.
- Container Runtimes daemons for working with Kubernetes CRIs. See CRI-O. We are working to integrate libpod into CRI-O to share containers and backend code with Podman.
OCI Projects Plans
The plan is to use OCI projects and best of breed libraries for different aspects:
- Runtime: runc (or any OCI compliant runtime) and oci runtime tools to generate the spec
- Images: Image management using containers/image
- Storage: Container and image storage is managed by containers/storage
- Networking: Networking support through use of CNI
- Builds: Builds are supported via Buildah.
- Conmon: Conmon is a tool for monitoring OCI runtimes. It is part of the CRI-O package
