# 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](https://github.com/projectatomic/skopeo/).
* Container Runtimes daemons for working with Kubernetes CRIs. See [CRI-O](https://github.com/kubernetes-incubator/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](https://github.com/opencontainers/runc) (or any OCI compliant runtime) and [oci runtime tools](https://github.com/opencontainers/runtime-tools) to generate the spec
- Images: Image management using [containers/image](https://github.com/containers/image)
- Storage: Container and image storage is managed by [containers/storage](https://github.com/containers/storage)
- Networking: Networking support through use of [CNI](https://github.com/containernetworking/cni)
- Builds: Builds are supported via [Buildah](https://github.com/projectatomic/buildah).
- Conmon: [Conmon](https://github.com/kubernetes-incubator/cri-o) is a tool for monitoring OCI runtimes. It is part of the CRI-O package
## Podman Information for Developers
**[Installation notes](/install.md)**
Information on how to install Podman in your environment.
**[OCI Hooks Support](pkg/hooks/README.md)**
Information on how Podman configures [OCI Hooks][spec-hooks] to run when launching a container.
**[Podman Commands](/commands.md)**
A list of the Podman commands with links to their man pages and in many cases videos
showing the commands in use.
**[Podman Usage Transfer](/transfer.md)**
Useful information for ops and dev transfer as it relates to infrastructure that utilizes Podman. This page
includes tables showing Docker commands and their Podman equivalent commands.
**[Podman API](/API.md)**
Documentation on the Podman API using [Varlink](https://www.varlink.org/).
**[Tutorials](docs/tutorials)**
Tutorials on using Podman.
**[Contributing](CONTRIBUTING.md)**
Information about contributing to this project.
### Current Roadmap
1. Varlink API for Podman
1. Integrate libpod into CRI-O to replace its existing container management backend
1. Pod commands for Podman
1. Rootless containers
1. Support for cleaning up containers via post-run hooks
