Pouch's vision is to advance container ecosystem and promote container standards [OCI(Open Container Initiative)](https://github.com/opencontainers), so that container technologies become the foundation for application development in the Cloud era. Pouch can pack, deliver and run any application. It provides applications with a lightweight runtime environment with strong isolation and minimal overhead. Pouch isolates applications from varying runtime environment, and minimizes operational workload. Pouch minimizes the effort for application developers to write Cloud-native applications, or to migrate legacy ones to a Cloud platform. ## Features Pouch's most important features are: - **Security**: Pouch is designed to be secure by default. Include lots of security features, like hypervisor-based container technology, lxcfs, patched Linux kernel and so on. - **P2P distribution**: Pouch utilizes [Dragonfly](https://github.com/alibaba/dragonfly), a P2P-base distribution system, to achieve lightning-fast container image distribution. - **Rich container**: Besides the common ways of running container, Pouch includes a `rich container` mode, which integrates more services, hooks, and many others container internals to guarantee container's running like usual. - **Kernel compatibility**: Enables OCI-compatible runtimes to work on old kernel versions, like linux kernel 2.6.32+. - **Simplicty**: Very few steps needed to setup Pouch. ## Architecture We describe Pouch's architecture from two dimensions: **ecosystem architecture** which illustrates how Pouch fits into the container ecosystem and **component architecture** which describes the interactions between various components inside Pouch. For more details, please refer to file [architecture.md](docs/architecture.md). ## Advantages Pouch has lots of advantages over VM technologies. Two of the most impressive ones are **Resource Utilization** and **Application Centric**. ### Resource Utilization Pouch significantly improves resource utilization: * Pouch is compatible with OCI image spec. Applications can minimize their storage usage with layered image structure. * Incremental image distribution, saves datacenter bandwidth consumption. * Significantly less runtime overhead than VM-based technologies. ### Application Centric Pouch offers a more "application centric" approach for application development: * Pouch provides strong runtime isolation between applications, with cutting-edge technology both within kernel support and beyond kernel mode. * Pouch enables cross-platform and cross-OS application delivery. * Pouch supports standardized application image spec, so application sharing and reusing becomes trivial for developers and operators. ## Getting Started You can easily setup a basic Pouch environment, see [INSTALLATION.md](INSTALLATION.md). You'll need to install a few packages before starting `pouchd`, which starts a container management service. The service can be accessed through the `pouch` CLI or RPC calls. For more details, please refer to [CLI Manual](docs/commandline) and [API Manual](docs/api). ## Contributing You are warmly welcomed to hack on Pouch.
