Overview¶

Add a pulp3 plugin to support OSTree. Most of the heavy lifting can be canablized from the pulp2 plugin.
Mainly just need to:

• Port mongoengine models to django models.
• Add django scaffolding (viewset, serializers, etc).
• Port code from Steps to tasks.
• Directly reuse the libostree (lib) module.

Model¶

Metadata(GenericKeyValueModel):

Remote(Model):
"This is a local OSTree repository where everything is stored."

• url (CharField)
• storage_path (CharField)

Commit(Model):

• hash (CharField)
• metadata (GenericKeyValueRelation) => Metadata (cascade)
