Getting Started

Pyshop is a private repository for python packages.

The aim is to split private projects in distinct private packages and keep a
setup.py clean and working, by declaring all dependencies, exactly as public
packages on PyPI.

Pyshop also proxies and caches packages from PyPI safely using SSL and checking server
certificate.

Pyshop uses clear and simple ACLs to manage privileges:

  • an installer group that can only download release files,
  • a developer group that can download and upload release files and browse the
    website,
  • an admin group that has developer privileges and accounts management.

Since pyshop is intended to host private packages, every user, including pip,
must be authenticated by login and password.

Installation

Using A virtualenv with Python 3

::

$ cd /srv
$ sudo mkdir pyshop
$ sudo chown $(whoami) pyshop
$ cd pyshop
$ pyvenv .
(pyshop)$ source bin/activate
(pyshop)$ pip install "pyshop[waitress]"
(pyshop)$ cp pyshop.sample.ini pyshop.ini
(pyshop)$ vim pyshop.ini  # change at least the pyshop.cookie_key setting
(pyshop)$ pyshop_setup pyshop.ini  # Create the database
(pyshop)$ pserve pyshop.ini        # start pyshop CTRL+C to stop

.. Note::

If you are using python2 and the pyshop you may not have the pyshop.sample.ini file, you can
download it with:

::

  (pyshop)$ curl -o pyshop.ini https://raw.githubusercontent.com/mardiros/pyshop/master/pyshop.sample.ini

You should edit the pyshop.ini file in order to configure the
pyshop.cookie_key and the host:port that hosts the service. When the server
is running visit the website, http://localhost:8000/ by default, to check
everything is fine.

For production usage, you should create accounts with the developer group.
Visit http://localhost:8000/pyshop/user with the admin account to create
accounts.

You also should also use an https reverse proxy. Python packaging core uses
HTTP basic authentication: it sends user/password in clear.

The pythop.sample.ini file use waitress as the default WSGI server, but,
if you are familiar with another WSGI server that support paste format,
you could use it.

Daemonize with systemd on linux

Pyramid 1.8 has removed deamonized options_ you have to use a process manager.

Here is a simple way to daemonise it undex linux that use systemd

::

  (pyshop)$ curl -o pyshop.service https://raw.githubusercontent.com/mardiros/pyshop/master/pyshop.sample.service
  (pyshop)$ sudo mv pyshop.service /etc/systemd/system/pyshop.service

.. note::

you may edit the pyshop.service file to adapt path in case you install it

_Pyramid 1.8 has removed deamonized options: http://docs.pylonsproject.org/projects/pyramid/en/latest/whatsnew-1.8.html#backwards-incompatibilities

Using Docker

Currently, there is an image of pyshop used for development purpose,
it support both MySQL and PostgreSQL. The PostgreSQL integration is
fully operation, you can run a new Pyshop install using docker-compose,
with the command:

::

docker-compose up pgpyshop

It will create the database with the default pyshop users:

  • privileged user: login admin, password: changeme
  • unprivileged user: login pip, password changeme

If you want to use a different orchestrator, you have to link the postgresql
container to Pyshop container with the name postgresql.localdomain

The MySQL support does not automate the database setup right now.

The official Docker image of Pyshop is available here on the Docker Hub:

https://registry.hub.docker.com/u/mardiros/pyshop/

Configuring your environment

Here are all configuration files you will need to modify for usual python tools
to use your newly deployed private repository.

~/.pip/pip.conf

Configuration used by pip. This is a user file, you can set a developer or
the generic pip account.

::

[global]
# when mirroring a package, pyshop retrieves information from PyPI and
# stores it in its database. Be patient, it is not so long.
default-timeout = 120
timeout = 120

[install]
index-url = http://pip:changeme@localhost:8000/simple/

[search]
index = http://pip:changeme@localhost:8000/pypi

.. note::

If you are using a WSGI server that kills requests if it is too long, like
uWSGI or gunicorn, set an appropriate timeout for this service too.

.. note::

The search funciton is not working with Python 3

setup.cfg and pydistutils.cfg

setup.cfg and pydistutils.cfg are used when running python setup.py develop
to install your package or when using easy_install. You should use a generic
account with installer privileges only, shared by all developers.

This setting can be set per project or in user $HOME (see
setuptools documentation_ for details)

.. _setuptools documentation: https://pythonhosted.org/setuptools/easy_install.html#configuration-files

::

[easy_install]
index-url = http://pip:changeme@localhost:8000/simple/

This should work now::

python setup.py develop

~/.pypirc

Configuration used by setuptools to upload files.
All developers should have this configuration in their $HOME to upload
packages.

::

[distutils]
index-servers =
    pyshop

[pyshop]
username: admin  # or create an account in pyshop admin interface
password: changeme
repository: http://localhost:8000/simple/

This should work now::

python setup.py sdist upload -v -r pyshop
