Uploading Content

Uploading a unit into a repository is a four step process:

  • Create an upload request in Pulp. Pulp will provide an ID that is used for subsequent operations.
  • Upload the bits for the new file. For large files, this can be done through multiple calls. This step is entirely optional; it is possible that a unit purely consists of metadata and possibly creating relationships to other units.
  • Once the file is uploaded, metadata about the unit itself is provided to Pulp along with a destination repository. The repository’s importer is contacted to perform the import which adds the unit to the database and associates it to the repository.
  • Once the caller is finished importing the uploaded file, a request is sent to Pulp to delete the uploaded file from Pulp’s temporary storage.

Uploaded files are not in the Pulp inventory until the import step. Units must be imported into a repository that has an importer associated with it that is capable of handling the unit type.

Creating an Upload Request

Informs Pulp of the desire to upload a new content unit. Pulp will perform any preparation steps in the server and return an upload ID that is used to further work with the upload request.

Method: POST
Path: /pulp/api/v2/content/uploads/
Permission: create
Request Body Contents: None
Response Codes:
  • 201 - if the request to upload a file is granted
  • 500 - if the server cannot initialize the storage location for the file to be uploaded
Return: upload ID to identify this upload request in future calls

Sample 201 Response Body: 

{
 "_href": "/pulp/api/v2/content/uploads/cfb1fed0-752b-439e-aa68-fba68eababa3/",
 "upload_id': "cfb1fed0-752b-439e-aa68-fba68eababa3"
}

Upload Bits

Sends a portion of the contents of the file being uploaded to the server. If the entire file cannot be sent in a single call, the caller may divide up the file and provide offset information for Pulp to use when assembling it.

Method: PUT
Path: /pulp/api/v2/content/uploads/<upload_id>/<offset/
Permission: update
Request Body Contents: The body of the request is the content to store in the file starting at the offset specified in the URL.
Response Codes:
  • 200 - if the content was successfully saved to the file
Return: none

Import into a Repository

Provides metadata about the uploaded unit and requests Pulp import it into the inventory and associate it with the given repository. This call is made on the repository itself and the URL reflects this accordingly.

Method: POST
Path: /pulp/api/v2/repositories/<repo_id>/actions/import_upload/
Permission: update
Request Body Contents:
  • upload_id (string) - identifies the upload request being imported
  • unit_type_id (string) - identifies the type of unit the upload represents
  • unit_key (object) - unique identifier for the new unit; the contents are contingent on the type of unit being uploaded
  • unit_metadata (object) - (optional) extra metadata describing the unit; the contents will vary based on the importer handling the import
  • override_config (object) - (optional) importer configuration values that override the importer’s default configuration
Response Codes:
  • 202 - if the request for the import was accepted but postponed until later
Return: a Call Report The result field in the call report will be defined by the importer used

Tags: The task created will have the following tags. "pulp:repository:<repo_id>", "pulp:action:import_upload"

Sample Request: 

{
   "override_config": {},
   "unit_type_id": "srpm",
   "upload_id": "768b18c1-fef1-4443-bd5b-a4cc9bda3b03",
   "unit_key": {},
   "unit_metadata": {"checksum_type": null}
}

Delete an Upload Request

Once the uploaded file has been successfully imported and no further operations are desired, the caller should delete the upload request from the server.

Method: DELETE
Path: /pulp/api/v2/content/uploads/<upload_id>/
Permission: delete
Query Parameters: None
Response Codes:
  • 200 - if the upload was successfully deleted
  • 404 - if the given upload ID is not found
Return: none

List All Upload Requests

Returns an array of IDs for all upload requests currently in the server.

Method: GET
Path: /pulp/api/v2/content/uploads/
Permission: read
Query Parameters: None
Response Codes:
  • 200 - for a successful lookup
Return: array of IDs for all upload requests on the server; empty array if there are none

Sample 200 Response Body: 

{
 "upload_ids': ["cfb1fed0-752b-439e-aa68-fba68eababa3"]
}
