A file. They usually belong to a content unit but may be used elsewhere (e.g. for PublishedArtifacts).

ContentGuard

A pluggable content protection mechanism that can be added to a Distribution, and is used exclusively by the content app to only hand out binary data to trusted clients. “Trusted users” are defined by the type of ContentGuard used.

Content
content unit

Content are the smallest units of data that can be added and removed from repositories. When singular, “content unit” should be used. Each content unit can have multiple artifacts. Each content unit has a type (like .rpm or .deb) which that is defined by a plugin.

content app

An aiohttp.server app provided by pulpcore that serves content through Distributions.

Distribution

User facing object that configures the content app to serve either a RepositoryVersion, a Repository, or a Publication.

Exporter

Exporters can push a Repository Version, a Repository, or a Publication content to a location outside of Pulp. Some example locations include a remote server or a file system location.

on-demand content

Content that was synchronized into Pulp but not yet saved to the filesystem. The Content’s Artifacts are fetched at the time they are requested. On-demand content is associated with a Remote that knows how to download those Artifacts.

plugin

A Django app that exends pulpcore to add more features to Pulp. Plugins are most commonly used to add support for one or more types of Content.

Publication

The metadata and artifacts of the content units in a RepositoryVersion. Publications are served by the content app when they are assigned to a Distribution.

pulpcore

A python package offering users a REST API and plugin writers a Plugin API Reference. It is plugin-based and manages Content.

Remote

User facing settings that specify how Pulp should interact with an external Content source.

Repository

A versioned set of content units.

RepositoryVersion

An immutable snapshot of the set of content units that are in a Repository.

sync

A plugin defined task that fetches Content from an external source using a Remote. The task adds and/or removes the content units to a Repository, creating a new RepositoryVersion.

type

Each content unit has a type (ex. rpm package or container tag) which is defined by a Plugin.
