Glossary

Bundle

A directory structure that is written ahead of time, distributed, and used to seed the runtime for creating a container and launching a process within it.

Configuration

The config.json file in a bundle which defines the intended container and container process.

Container

An environment for executing processes with configurable isolation and resource limitations. For example, namespaces, resource limits, and mounts are all part of the container environment.

Container namespace

On Linux, a leaf in the namespace hierarchy in which the configured process executes.

JSON

All configuration JSON MUST be encoded in UTF-8. JSON objects MUST NOT include duplicate names. The order of entries in JSON objects is not significant.

Runtime

An implementation of this specification. It reads the configuration files from a bundle, uses that information to create a container, launches a process inside the container, and performs other lifecycle actions.

Runtime namespace

On Linux, a leaf in the namespace hierarchy from which the runtime process is executed. New container namespaces will be created as children of the runtime namespaces.
