About Pulp 3

Pulp 3 builds on the achievements of Pulp 2, with a renewed focus on repository management. Pulp 3 is more than an update of Pulp 2. Pulp 3 is the result of years of feedback from Pulp 2 production scenarios and serves to address key concerns that could not be resolved within the existing Pulp 2 architecture.

Pulp 3 reduces the challenges and dependencies that users experienced with Pulp 2. Built on Django, and using open standards such as OpenAPI, Pulp 3 has increased reliability and flexibility while reducing the code base. Plugin writing has become easier thanks to the improved Plugin API. Performance speeds, data integrity, and safety features, such as roll back to specific versions, have guided the development of Pulp 3.

Pulp 3 and Pulp 2 have several conceptual differences. For more information about conceptual and terminology differences between Pulp 3 and Pulp 2, see Renamed concepts.

Pulp 3 vs Pulp 2 At A Glance

Pulp 3 has the following advantages and features when compared to Pulp 2:

  • Improved performance and data integrity. Pulp 3 moves from MongoDB to PostgreSQL.
  • Faster performance. On testing, synchronizing in Pulp 3 ranges from two to eight times faster than Pulp 2.
  • Versioned repositories feature. New ability to rollback safely to earlier versions.
  • Disk storage and speed solutions. Select from multiple synchronization options for all content types to suit specific environmental requirements.
  • More storage options. Store content in the cloud with storage services like S3 and Azure.
  • Simplified containerized installation
  • Client bindings make Pulp’s API language agnostic, requiring no customization.
  • Browseable, auto-documented, OpenAPI.
  • Python’s PyPI replaces RPMs as the main packaging method, which allows for easy installation across Linux distributions.
  • Improvements to the Plugin API ensures compatibility with Pulp core and has led to an increasing list of Plugins.
  • Fine grained Role-based access control (not all plugins might have this ready yet).
  • The Pulp 3 CLI.

Functionality that has been dropped or replaced entirely with Pulp 3

System management features, which were present in Pulp 2, have been removed so that Pulp 3 maintains focus on providing the best and most stable repository management experience. Other tools, such as Ansible, can be used for system management. Some other services have been dropped as part of Pulp 3. For more information, see Deprecating Consumers.

  • Pulp agent
  • Scheduled tasks
  • The entire Celery stack has been replaced by RQ
  • Pulp 2’s nodes concept has been removed in favor of Pulp server-to-server syncing

Functionality that does not currently exist but might be subject to change

  • No Puppet plugin is available
