容器标准
========================================

OCI
----------------------------------------
开放容器标准 (Open Container Initiative, OCI) 是用于规范容器格式和运行时行业标准。目前OCI提出的规范有：

- `OCI Runtime Specification <https://github.com/opencontainers/runtime-spec>`_
- `OCI Image Format <https://github.com/opencontainers/image-spec>`_
- `OCI Distribution Specification <https://github.com/opencontainers/distribution-spec>`_

CRI
----------------------------------------
容器运行时 (Container Runtime Interface, CRI) 定义了容器和镜像的接口，目前官方支持的容器运行时包括Docker、Containerd、CRI-O和frakti。
