Features

RPM Support includes a number of features that are not found in the generic Pulp platform, the most important of which are described below.

Types

Pulp RPM supports the following types:

  • RPM
  • DRPM
  • SRPM
  • Erratum
  • Distribution
  • Package Group
  • Package Category

Errata

Red Hat provides security, bug fix, and enhancement updates for supported Red Hat Enterprise products. These security updates are provided through the Red Hat CDN, and are described by errata. Pulp supports these errata types with a number of related features.

Errata are synchronized from upstream repositories. Errata can also be copied from one repository to another. Administrators can also upload their own errata to a repository. Please see the Recipes documentation to learn how to perform these operations.

Protected Repositories

Red Hat protects its repositories with SSL-based entitlement certificates. Pulp supports both ends of that operation:

Each Pulp repository can be configured with a client entitlement certificate and key that it will use to retrieve packages from a remote repository. This is only required when the remote repository is protected, such as when connecting to the Red Hat CDN.

Pulp can be supplied a CA certificate that it will use to verify the authenticity of client certificates when clients try to access Pulp-hosted repositories. This is only required when you want to protect a Pulp-hosted repository. Repositories can have these protection settings specified individually, or they can be set globally for all RPM-related repositories.

For each Pulp-hosted repository that is protected, a consumer certificate can be supplied that will be distributed to consumers when they bind. That certificate will allow them to access the protected repository.

Export

In addition to publishing repositories as normal yum repositories over HTTP or HTTPS, it is also possible to export repositories to ISO images, which are published over HTTP or HTTPS, or to a directory on the Pulp server. Large repositories may be split into several ISOs.

Proxy Settings

When retrieving packages from a remote repository, Pulp can use a proxy and can supply basic authentication credentials to that proxy.

Bandwidth Throttling

When downloading packages from a remote source, Pulp can limit the speed at which data is transferred. The number of downloader threads can also be specified.
