Publish

Publish tasks generate publications. A publication contains metadata and artifacts associated with content contained within a RepositoryVersion.

Using a ~pulpcore.plugin.models.Publication context manager is highly encouraged. On context exit, the complete attribute is set True provided that an exception has not been raised. In the event an exception has been raised, the publication is deleted.

One of the ways to perform publishing:

  • Find ~pulpcore.plugin.models.ContentArtifact objects which should be published
  • For each of them create and save instance of ~pulpcore.plugin.models.PublishedArtifact which refers to ~pulpcore.plugin.models.ContentArtifact and ~pulpcore.app.models.Publication to which this artifact belongs.
  • Generate and write to a disk repository metadata
  • For each of the metadata objects create and save instance of ~pulpcore.plugin.models.PublishedMetadata which refers to a corresponding file and ~pulpcore.app.models.Publication to which this metadata belongs.
  • Use ~pulpcore.plugin.models.ProgressReport to report progress of some steps if needed.
