Publish and Host

This section assumes that you have a repository with content in it. To do this, see the Synchronize a Repository or Upload and Manage Content documentation.

Create a Publication (manually)

Kick off a publish task by creating a new publication. The publish task will generate all the metadata that pip needs to install packages (although it will need to be hosted through a Distribution before it is consumable).

# Create a new publication specifying the repository_version.
# Alternatively, you can specify just the repository, and Pulp will assume the latest version.
pulp python publication create --repository foo --version 1

# Publications can only be referenced through their pulp_href
PUBLICATION_HREF=$(pulp python publication list | jq -r .[0].pulp_href)

{
  "pulp_href": "/pulp/api/v3/publications/python/pypi/cad6007d-7172-41d1-8c22-0ec95e1d242a/",
  "pulp_created": "2021-03-09T04:30:16.686784Z",
  "repository_version": "/pulp/api/v3/repositories/python/python/8fbb24ee-dc91-44f4-a6ee-beec60aa542d/versions/1/",
  "repository": "/pulp/api/v3/repositories/python/python/8fbb24ee-dc91-44f4-a6ee-beec60aa542d/",
  "distributions": []
}

Host a Publication (Create a Distribution)

To host a publication, (which makes it consumable by pip), users create a distribution which will serve the associated publication at /pypi/<distribution.base_path>/

# Distributions are created asynchronously. Create one, and specify the publication that will
# be served at the base path specified.
pulp python distribution create --name foo --base-path foo --publication "$PUBLICATION_HREF"

Response:

{
   "pulp_href": "/pulp/api/v3/distributions/python/pypi/4839c056-6f2b-46b9-ac5f-88eb8a7739a5/",
   "pulp_created": "2021-03-09T04:36:48.289737Z",
   "base_path": "foo",
   "base_url": "/pypi/foo/",
   "content_guard": null,
   "pulp_labels": {},
   "name": "foo",
   "publication": "/pulp/api/v3/publications/python/pypi/a09111b1-6bce-43ac-aed7-2e8441c22704/"
 }

Automate Publication and Distribution

With a little more initial setup, you can have publications and distributions for your repositories updated automatically when new repository versions are created.

# This configures the repository to produce new publications when a new version is created
pulp python repository update --name foo --autopublish
# This configures the distribution to be track the latest repository version for a given repository
pulp python distribution update --name foo --repository foo

Warning

Support for automatic publication and distribution is provided as a tech preview in Pulp 3. Functionality may not work or may be incomplete. Also, backwards compatibility when upgrading is not guaranteed.

Use the newly created distribution

The metadata and packages can now be retrieved from the distribution:

$ http $BASE_ADDR/pypi/foo/simple/
$ http $BASE_ADDR/pypi/foo/simple/shelf-reader/

The content is also pip installable:

$ pip install --trusted-host localhost -i $BASE_ADDR/pypi/foo/simple/ shelf-reader

If you don’t want to specify the distribution path every time, you can modify your pip.conf file. See the pip docs for more detail.:

$ cat pip.conf
[global]
index-url = http://localhost:24817/pypi/foo/simple/

The above configuration informs pip to install from pulp:

$ pip install --trusted-host localhost shelf-reader
