``pypiserver`` is a minimal PyPI_ compatible server for ``pip`` or ``easy_install``.
It is based on bottle_ and serves packages from regular directories.
Wheels, bdists, eggs and accompanying PGP-signatures can be uploaded
either with ``pip``, ``setuptools``, ``twine``, ``pypi-uploader``, or simply copied
with ``scp``.

.. note::
   The official software powering PyPI_ is Warehouse_. However, Warehouse_
   is fairly specialized to be ``pypi.org``'s own software, and should not
   be used in other contexts. In particular, it does not officially support
   being used as a custom package index by users wishing to serve their own
   packages.

   ``pypiserver`` implements the same interfaces as `PyPI`_, allowing
   standard Python packaging tooling such as ``pip`` and ``twine`` to
   interact with it as a package index just as they would with PyPI_, while
   making it much easier to get a running index server.

Quickstart: Installation and Usage
==================================

``pypiserver`` works with Python 3.6+ and PyPy3.

Older Python versions may still work, but they are not tested.

For legacy Python versions, use ``pypiserver-1.x`` series. Note that these are
not officially supported, and will not receive bugfixes or new features.

.. Tip::
   The commands below work on a unix-like operating system with a posix shell.
   The ``'~'`` character expands to user's home directory.

   If you're using Windows, you'll have to use their "Windows counterparts".
   The same is true for the rest of this documentation.

1. Install ``pypiserver`` with this command::

    pip install pypiserver                # Or: pypiserver[passlib,cache]
    mkdir ~/packages                      # Copy packages into this directory.

   See also `Alternative Installation methods`_.

2. Copy some packages into your ``~/packages`` folder and then
   get your ``pypiserver`` up and running::

    pypi-server run -p 8080 ~/packages &      # Will listen to all IPs.

3. From the client computer, type this::

    # Download and install hosted packages.
    pip install --extra-index-url http://localhost:8080/simple/ ...

    # or
    pip install --extra-index-url http://localhost:8080 ...

    # Search hosted packages.
    pip search --index http://localhost:8080 ...

    # Note that pip search does not currently work with the /simple/ endpoint.

   See also `Client-side configurations`_ for avoiding tedious typing.

4. Enter ``pypi-server -h`` in the cmd-line to print a detailed usage message::

    start PyPI compatible package server serving packages from PACKAGES_DIRECTORY. If PACKAGES_DIRECTORY is not given on the command line, it uses the default ~/packages. pypiserver scans this directory recursively for packages. It skips packages and directories starting with a dot. Multiple package directories may be specified.

    positional arguments:
      {run,update}
        run                 Run pypiserver, serving packages from
                            PACKAGES_DIRECTORY
        update              Handle updates of packages managed by pypiserver. By
                            default, a pip command to update the packages is
                            printed to stdout for introspection or pipelining. See
                            the `-x` option for updating packages directly.

    options:
      -h, --help            show this help message and exit
      -v, --verbose         Enable verbose logging; repeat for more verbosity.
      --log-file FILE       Write logging info into this FILE, as well as to
                            stdout or stderr, if configured.
      --log-stream STREAM   Log messages to the specified STREAM. Valid values are
                            stdout, stderr, and none
      --log-frmt FORMAT     The logging format-string.  (see `logging.LogRecord`
                            class from standard python library)
      --hash-algo HASH_ALGO
                            Any `hashlib` available algorithm to use for
                            generating fragments on package links. Can be disabled
                            with one of (0, no, off, false).
      --backend {auto,simple-dir,cached-dir}
                            A backend implementation. Keep the default 'auto' to
                            automatically determine whether to activate caching or
                            not
      --version             show program's version number and exit

More details about ``pypi-server run``
--------------------------------------

Enter ``pypi-server run -h`` in the cmd-line to print a detailed usage
message *about starting the server*::

                       [package_directory [package_directory ...]]

  positional arguments:
    package_directory     The directory from which to serve packages.

  optional arguments:
    -h, --help            show this help message and exit
    -v, --verbose         Enable verbose logging; repeat for more verbosity.
    --log-file FILE       Write logging info into this FILE, as well as to stdout or stderr, if configured.
    --log-stream STREAM   Log messages to the specified STREAM. Valid values are stdout, stderr, and none
    --log-frmt FORMAT     The logging format-string.  (see `logging.LogRecord` class from standard python library)
    --hash-algo HASH_ALGO
                          Any `hashlib` available algorithm to use for generating fragments on package links. Can be disabled with one of (0, no, off,
                          false).
    --backend {auto,simple-dir,cached-dir}
                          A backend implementation. Keep the default 'auto' to automatically determine whether to activate caching or not
    --version             show program's version number and exit
    -p PORT, --port PORT  Listen on port PORT (default: 8080)
    -i HOST, -H HOST, --interface HOST, --host HOST
                          Listen on interface INTERFACE (default: 0.0.0.0)
    -a AUTHENTICATE, --authenticate AUTHENTICATE
                          Comma-separated list of (case-insensitive) actions to authenticate (options: download, list, update; default: update).
                          
                          Any actions not specified are not authenticated, so to authenticate downloads and updates, but allow unauthenticated viewing of
                          the package list, you would use:
                          
                            pypi-server -a 'download, update' -P ./my_passwords.htaccess
                          
                          To disable authentication, use:
                          
                            pypi-server -a . -P .
                          
                          See the `-P` option for configuring users and passwords.
                          
                          Note that when uploads are not protected, the `register` command is not necessary, but `~/.pypirc` still needs username and
                          password fields, even if bogus.
    -P PASSWORD_FILE, --passwords PASSWORD_FILE
                          Use an apache htpasswd file PASSWORD_FILE to set usernames and passwords for authentication.
                          
                          To allow unauthorized access, use:
                          
                            pypi-server -a . -P .
                          
    --disable-fallback    Disable the default redirect to PyPI for packages not found in the local index.
    --fallback-url FALLBACK_URL
                          Redirect to FALLBACK_URL for packages not found in the local index.
    --health-endpoint HEALTH_ENDPOINT
                          Configure a custom liveness endpoint.
                          It always returns 200 Ok if the service is up.
                          Otherwise, it means that the service is not responsive.
    --server METHOD       Use METHOD to run the server. Valid values include paste, cherrypy, twisted, gunicorn, gevent, wsgiref, and auto. The default is to
                          use "auto", which chooses one of paste, cherrypy, twisted, or wsgiref.
    -o, --overwrite       Allow overwriting existing package files during upload.
    --welcome HTML_FILE   Use the contents of HTML_FILE as a custom welcome message on the home page.
    --cache-control AGE   Add "Cache-Control: max-age=AGE" header to package downloads. Pip 6+ requires this for caching. AGE is specified in seconds.
    --log-req-frmt FORMAT
                          A format-string selecting Http-Request properties to log; set to '%s' to see them all.
    --log-res-frmt FORMAT
                          A format-string selecting Http-Response properties to log; set to '%s' to see them all.
    --log-err-frmt FORMAT
                          A format-string selecting Http-Error properties to log; set to '%s' to see them all.

More details about ``pypi-server update``
-----------------------------------------

Enter ``pypi-server update -h`` in the cmd-line to print a detailed usage
message *about updating the managed packages*::

  usage: pypi-server update [-h] [-v] [--log-file FILE] [--log-stream STREAM] [--log-frmt FORMAT] [--hash-algo HASH_ALGO]
                            [--backend {auto,simple-dir,cached-dir}] [--version] [-x] [-d DOWNLOAD_DIRECTORY] [-u] [--blacklist-file IGNORELIST_FILE]
                            [package_directory [package_directory ...]]

  positional arguments:
    package_directory     The directory from which to serve packages.

  optional arguments:
    -h, --help            show this help message and exit
    -v, --verbose         Enable verbose logging; repeat for more verbosity.
    --log-file FILE       Write logging info into this FILE, as well as to stdout or stderr, if configured.
    --log-stream STREAM   Log messages to the specified STREAM. Valid values are stdout, stderr, and none
    --log-frmt FORMAT     The logging format-string. (see `logging.LogRecord` class from standard python library)
    --hash-algo HASH_ALGO
                          Any `hashlib` available algorithm to use for generating fragments on package links. Can be disabled with one of (0, no, off,
                          false).
    --backend {auto,simple-dir,cached-dir}
                          A backend implementation. Keep the default 'auto' to automatically determine whether to activate caching or not
    --version             show program's version number and exit
    -x, --execute         Execute the pip commands rather than printing to stdout
    -d DOWNLOAD_DIRECTORY, --download-directory DOWNLOAD_DIRECTORY
                          Specify a directory where packages updates will be downloaded. The default behavior is to use the directory which contains the
                          package being updated.
    -u, --allow-unstable  Allow updating to unstable versions (alpha, beta, rc, dev, etc.)
    --blacklist-file IGNORELIST_FILE, --ignorelist-file IGNORELIST_FILE
                          Don't update packages listed in this file (one package name per line, without versions, '#' comments honored). This can be useful
                          if you upload private packages into pypiserver, but also keep a mirror of public packages that you regularly update. Attempting to
                          pull an update of a private package from `pypi.org` might pose a security risk - e.g. a malicious user might publish a higher
                          version of the private package, containing arbitrary code.

Client-Side Configurations
==========================

Always specifying the the pypi url on the command line is a bit
cumbersome. Since ``pypiserver`` redirects ``pip/easy_install`` to the
``pypi.org`` index if it doesn't have a requested package, it is a
good idea to configure them to always use your local pypi index.

Configuring ``pip``
-------------------

For ``pip`` command this can be done by setting the environment variable
``PIP_EXTRA_INDEX_URL`` in your ``.bashr/.profile/.zshrc``::

  export PIP_EXTRA_INDEX_URL=http://localhost:8080/simple/

or by adding the following lines to ``~/.pip/pip.conf``::

  [global]
  extra-index-url = http://localhost:8080/simple/

.. Note::
   If you have installed ``pypiserver`` on a remote url without *https*
   you will receive an "untrusted" warning from *pip*, urging you to append
   the ``--trusted-host`` option.  You can also include this option permanently
   in your configuration-files or environment variables.

Configuring ``easy_install``
----------------------------

For ``easy_install`` command you may set the following configuration in
``~/.pydistutils.cfg``::

  [easy_install]
  index_url = http://localhost:8080/simple/


Uploading Packages Remotely
===========================

Instead of copying packages directly to the server's folder (i.e. with ``scp``),
you may use python tools for the task, e.g. ``python setup.py upload``.
In that case, ``pypiserver`` is responsible for authenticating the upload-requests.

.. Note::
  We strongly advise to password-protected your uploads!

  It is possible to disable authentication for uploads (e.g. in intranets).
  To avoid lazy security decisions, read help for ``-P`` and ``-a`` options.

*Apache*-Like Authentication (``htpasswd``)
-------------------------------------------

#. First make sure you have the *passlib* module installed (note that
   ``passlib>=1.6`` is required), which is needed for parsing the Apache
   *htpasswd* file specified by the ``-P``, ``--passwords`` option
   (see next steps)::

     pip install passlib

#. Create the Apache *htpasswd* file with at least one user/password pair
   with this command (you'll be prompted for a password)::

     htpasswd -sc htpasswd.txt <some_username>

   .. Tip:: Read this SO question for running `htpasswd` cmd
      under *Windows*:

         http://serverfault.com/questions/152950/how-to-create-and-edit-htaccess-and-htpasswd-locally-on-my-computer-and-then-u

      or if you have bogus passwords that you don't care because they are for
      an internal service (which is still "bad", from a security perspective...)
      you may use this public service:

         http://www.htaccesstools.com/htpasswd-generator/

   .. Tip:: When accessing pypiserver via the api, alternate authentication
      methods are available via the ``auther`` config flag. Any callable
      returning a boolean can be passed through to the pypiserver config in
      order to provide custom authentication. For example, to configure
      pypiserver to authenticate using the `python-pam`_::

        import pam
        pypiserver.default_config(auther=pam.authenticate)

      Please see `Using Ad-hoc authentication providers`_ for more information.

#. You  need to restart the server with the ``-P`` option only once
   (but user/password pairs can later be added or updated on the fly)::

     ./pypi-server run -p 8080 -P htpasswd.txt ~/packages &

Upload with ``setuptools``
--------------------------

#. On client-side, edit or create a ``~/.pypirc`` file with a similar content::

     [distutils]
     index-servers =
       pypi
       local

     [pypi]
     username:<your_pypi_username>
     password:<your_pypi_passwd>

     [local]
     repository: http://localhost:8080
     username: <some_username>
     password: <some_passwd>

#. Then from within the directory of the python-project you wish to upload,
   issue this command::

     python setup.py sdist upload -r local

Upload with ``twine``
---------------------

To avoid storing you passwords on disk, in clear text, you may either:

- use the ``register`` *setuptools*'s command with the ``-r`` option,
  like that::

     python setup.py sdist register -r local upload -r local

- use `twine`_ library, which
  breaks the procedure in two steps.  In addition, it supports signing
  your files with PGP-Signatures and uploading the generated `.asc` files
  to ``pypiserver``::

     twine upload -r local --sign -identity user_name ./foo-1.zip


Using the Docker Image
======================

Starting with version 1.2.5, official Docker images will be built for each
push to master, each dev, alpha, or beta release, and each final release.
The most recent full release will always be available under the tag ``latest``,
and the current master branch will always be available under the tag
``unstable``.

You can always check to see what tags are currently available at our
`Docker Repo`_.

To run the most recent release of ``pypiserver`` with Docker, simply::

    docker run pypiserver/pypiserver:latest run

This starts ``pypiserver`` serving packages from the ``/data/packages``
directory inside the container, listening on the container port 8080.

The container takes all the same arguments as the normal ``pypi-server``
executable, with the exception of the internal container port (``-p``),
which will always be 8080.

Of course, just running a container isn't that interesting. To map
port 80 on the host to port 8080 on the container::

    docker run -p 80:8080 pypiserver/pypiserver:latest run

You can now access your ``pypiserver`` at ``localhost:80`` in a web browser.

To serve packages from a directory on the host, e.g. ``~/packages``::

    docker run -p 80:8080 -v ~/packages:/data/packages pypiserver/pypiserver:latest run

To authenticate against a local ``.htpasswd`` file::

    docker run -p 80:8080 -v ~/.htpasswd:/data/.htpasswd pypiserver/pypiserver:latest run -P .htpasswd packages

You can also specify ``pypiserver`` to run as a Docker service using a
composefile. An example composefile is `provided <docker-compose.yml>`_.


.. _`docker repo`: https://hub.docker.com/r/pypiserver/pypiserver/tags/


Alternative Installation Methods
================================

When trying the methods below, first use the following command to check whether
previous versions of ``pypiserver`` already exist, and (optionally) uninstall them::

  # VERSION-CHECK: Fails if not installed.
  pypi-server --version

  # UNINSTALL: Invoke again until it fails.
  pip uninstall pypiserver

Installing the Very Latest Version
----------------------------------

In case the latest version in *pypi* is a pre-release, you have to use
*pip*'s `--pre` option.  And to update an existing installation combine it
with `--ignore-installed`::

  pip install pypiserver --pre -I

You can even install the latest ``pypiserver`` directly from *github* with the
following command, assuming you have *git* installed on your ``PATH``::

  pip install git+git://github.com/pypiserver/pypiserver.git


Recipes
=======

Managing the Package Directory
------------------------------

The ``pypi-server`` command has the ``update`` command that searches for updates of
available packages. It scans the package directory for available
packages and searches on pypi.org for updates. Without further
options ``pypi-server update`` will just print a list of commands which must
be run in order to get the latest version of each package. Output
looks like::

    $ ./pypi-server update 
    checking 106 packages for newer version

    .........u.e...........e..u.............
    .....e..............................e...
    ..........................

    no releases found on pypi for PyXML, Pymacs, mercurial, setuptools

    # update raven from 1.4.3 to 1.4.4
    pip -q install --no-deps  --extra-index-url https://pypi.org/simple/ -d /home/ralf/packages/mirror raven==1.4.4

    # update greenlet from 0.3.3 to 0.3.4
    pip -q install --no-deps  --extra-index-url https://pypi.org/simple/ -d /home/ralf/packages/mirror greenlet==0.3.4

It first prints for each package a single character after checking the
available versions on pypi. A dot(`.`) means the package is up-to-date, ``'u'``
means the package can be updated and ``'e'`` means the list of releases on
pypi is empty. After that it shows a *pip* command line which can be used
to update a one package. Either copy and paste that or run
``pypi-server update -x`` in order to really execute those commands. You need
to have *pip* installed for that to work however.

Specifying an additional ``-u`` option will also allow alpha, beta and
release candidates to be downloaded. Without this option these
releases won't be considered.

Serving Thousands of Packages
-----------------------------

By default, ``pypiserver`` scans the entire packages directory each time an
incoming HTTP request occurs. This isn't a problem for a small number of
packages, but causes noticeable slow-downs when serving thousands of packages.

If you run into this problem, significant speedups can be gained by enabling
pypiserver's directory caching functionality. The only requirement is to
install the ``watchdog`` package, or it can be installed during ``pypiserver``
installation, by specifying the ``cache`` extras option::

    pip install pypiserver[cache]

Additional speedups can be obtained by using your webserver's builtin
caching functionality. For example, if you are using `nginx` as a
reverse-proxy as described below in `Behind a reverse proxy`_, you can
easily enable caching. For example, to allow nginx to cache up to
10 gigabytes of data for up to 1 hour::

    proxy_cache_path /data/nginx/cache
                     levels=1:2
                     keys_zone=pypiserver_cache:10m
                     max_size=10g
                     inactive=60m
                     use_temp_path=off;

    server {
        # ...
        location / {
            proxy_cache pypiserver_cache;
            proxy_pass http://localhost:8080;
        }
    }

Using webserver caching is especially helpful if you have high request
volume. Using `nginx` caching, a real-world pypiserver installation was
able to easily support over 1000 package downloads/min at peak load.

Managing Automated Startup
--------------------------

There are a variety of options for handling the automated starting of
pypiserver upon system startup. Two of the most common are *systemd* and
*supervisor* for linux systems. For windows creating services with scripts isn't
an easy task without a third party tool such as *NSSM*.

Running As a ``systemd`` Service
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

``systemd`` is installed by default on most modern Linux systems and as such,
it is an excellent option for managing the pypiserver process. An example
config file for ``systemd`` can be seen below::

    [Unit]
    Description=A minimal PyPI server for use with pip/easy_install.
    After=network.target

    [Service]
    Type=simple
    # systemd requires absolute path here too.
    PIDFile=/var/run/pypiserver.pid
    User=www-data
    Group=www-data

    ExecStart=/usr/local/bin/pypi-server run -p 8080 -a update,download --log-file /var/log/pypiserver.log -P /etc/nginx/.htpasswd /var/www/pypi
    ExecStop=/bin/kill -TERM $MAINPID
    ExecReload=/bin/kill -HUP $MAINPID
    Restart=always

    WorkingDirectory=/var/www/pypi

    TimeoutStartSec=3
    RestartSec=5

    [Install]
    WantedBy=multi-user.target

Adjusting the paths and adding this file as ``pypiserver.service`` into your
``systemd/system`` directory will allow management of the pypiserver process with
``systemctl``, e.g. ``systemctl start pypiserver``.

More useful information about *systemd* can be found at
https://www.digitalocean.com/community/tutorials/how-to-use-systemctl-to-manage-systemd-services-and-units

Launching through ``supervisor``
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

`supervisor <http://supervisord.org/>`_ has the benefit of being a pure python
package and as such, it provides excellent cross-platform support for process
management. An example configuration file for ``supervisor`` is given below::

    [program:pypi]
    command=/home/pypi/pypi-venv/bin/pypi-server run -p 7001 -P /home/pypi/.htpasswd /home/pypi/packages
    directory=/home/pypi
    user=pypi
    autostart=true
    autorestart=true
    stderr_logfile=/var/log/pypiserver.err.log
    stdout_logfile=/var/log/pypiserver.out.log

From there, the process can be managed via ``supervisord`` using ``supervisorctl``.

Running As a service with ``NSSM`` (Windows)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Download NSSM from https://nssm.cc unzip to a desired location such as Program Files. Decide whether you are going
to use win32 or win64, and add that exe to environment PATH.

Create a start_pypiserver.bat::

    pypi-server run -p 8080 C:\Path\To\Packages &

Test the batch file by running it first before creating the service. Make sure you can access
the server remotely, and install packages. If you can, proceed, if not troubleshoot until you can.
This will ensure you know the server works, before adding NSSM into the mix.

From the command prompt::

    nssm install pypiserver

This command will launch a NSSM gui application::

    Path: C:\Path\To\start_pypiserver.bat
    Startup directory: Auto generates when selecting path
    Service name: pypiserver

There are more tabs, but that is the basic setup. If the service needs to be running with a certain
login credentials, make sure you enter those credentials in the logon tab.

Start the service::

    nssm start pypiserver

Other useful commands::

    nssm --help
    nssm stop <servicename>
    nssm restart <servicename>
    nssm status <servicename>

For detailed information please visit https://nssm.cc

Using a Different WSGI Server
-----------------------------

- The ``bottle`` web-server which supports many WSGI-servers, among others,
  ``paste``, ``cherrypy``, ``twisted`` and ``wsgiref`` (part of Python); you select
  them using the ``--server`` flag.

- You may view all supported WSGI servers using the following interactive code::

    >>> from pypiserver import bottle
    >>> list(bottle.server_names.keys())
    ['cgi', 'gunicorn', 'cherrypy', 'eventlet', 'tornado', 'geventSocketIO',
    'rocket', 'diesel', 'twisted', 'wsgiref', 'fapws3', 'bjoern', 'gevent',
    'meinheld', 'auto', 'aiohttp', 'flup', 'gae', 'paste', 'waitress']

- If none of the above servers matches your needs, invoke just the
  ``pypiserver:app()`` method which returns the internal WSGI-app WITHOUT
  starting-up a server - you may then send it to any WSGI server you like.
  Read also the `Utilizing the API`_ section.

- Some examples are given below - you may find more details in `bottle
  site <http://bottlepy.org/docs/dev/deployment.html#switching-the-server-backend>`_.

Apache (``mod_wsgi``)
~~~~~~~~~~~~~~~~~~~~~

To use your *Apache2* with ``pypiserver``, prefer to utilize ``mod_wsgi`` as
explained in `bottle's documentation <http://bottlepy.org/docs/dev/deployment.html#apache-mod-wsgi>`_.

.. Note::
   If you choose instead to go with ``mod_proxy``, mind that you may bump into problems
   with the prefix-path (see `#155 <https://github.com/pypiserver/pypiserver/issues/155>`_).

1. Adapt and place the following *Apache* configuration either into top-level scope,
   or inside some ``<VirtualHost>`` (contributed by Thomas Waldmann)::

        WSGIScriptAlias   /     /yoursite/wsgi/pypiserver-wsgi.py
        WSGIDaemonProcess       pypisrv user=pypisrv group=pypisrv umask=0007 \
                                processes=1 threads=5 maximum-requests=500 \
                                display-name=wsgi-pypisrv inactivity-timeout=300
        WSGIProcessGroup        pypisrv
        WSGIPassAuthorization On    # Required for authentication (https://github.com/pypiserver/pypiserver/issues/288)

        <Directory /yoursite/wsgi >
            Require all granted
        </Directory>

   or if using older ``Apache < 2.4``, substitute the last part with this::

        <Directory /yoursite/wsgi >
            Order deny,allow
            Allow from all
        </Directory>

2. Then create the ``/yoursite/cfg/pypiserver.wsgi`` file and make sure that
   the ``user`` and ``group`` of the ``WSGIDaemonProcess`` directive
   (``pypisrv:pypisrv`` in the example) have the read permission on it::

        import pypiserver

        conf = pypiserver.default_config(
            root =          "/yoursite/packages",
            password_file = "/yoursite/htpasswd", )
        application = pypiserver.app(**conf)


   .. Tip::
      If you have installed ``pypiserver`` in a virtualenv, follow ``mod_wsgi``'s
      `instructions <http://modwsgi.readthedocs.io/en/develop/user-guides/virtual-environments.html>`_
      and prepend the python code above with the following::

            import site

            site.addsitedir('/yoursite/venv/lib/pythonX.X/site-packages')

.. Note::
   For security reasons, notice that the ``Directory`` directive grants access
   to a directory holding the ``wsgi`` start-up script, alone; nothing else.

.. Note::
   To enable HTTPS support on Apache, configure the directive that contains the
   WSGI configuration to use SSL.

``gunicorn``
~~~~~~~~~~~~

The following command uses ``gunicorn`` to start ``pypiserver``::

  gunicorn -w4 'pypiserver:app(root="/home/ralf/packages")'

or when using multiple roots::

  gunicorn -w4 'pypiserver:app(root=["/home/ralf/packages", "/home/ralf/experimental"])'

``paste``
~~~~~~~~~

`paste <http://pythonpaste.org/>`_ allows to run multiple WSGI applications
under different URL paths. Therefore it is possible to serve different set
of packages on different paths.

The following example ``paste.ini`` could be used to serve stable and
unstable packages on different paths::

    [composite:main]
    use = egg:Paste#urlmap
    /unstable/ = unstable
    / = stable

    [app:stable]
    use = egg:pypiserver#main
    root = ~/stable-packages

    [app:unstable]
    use = egg:pypiserver#main
    root = ~/stable-packages
       ~/unstable-packages

    [server:main]
    use = egg:gunicorn#main
    host = 0.0.0.0
    port = 9000
    workers = 5
    accesslog = -

.. Note::
   You need to install some more dependencies for this to work, like::

        pip install paste pastedeploy gunicorn pypiserver

   The server can then start with::

        gunicorn_paster paste.ini


Behind a Reverse Proxy
----------------------

You can run ``pypiserver`` behind a reverse proxy as well.

Nginx
~~~~~

Extend your nginx configuration::

    upstream pypi {
      server              pypiserver.example.com:12345 fail_timeout=0;
    }

    server {
      server_name         myproxy.example.com;

      location / {
        proxy_set_header  Host $host:$server_port;
        proxy_set_header  X-Forwarded-Proto $scheme;
        proxy_set_header  X-Real-IP $remote_addr;
        proxy_pass        http://pypi;
      }
    }

As of pypiserver 1.3, you may also use the `X-Forwarded-Host` header in your
reverse proxy config to enable changing the base URL. For example if you
want to host pypiserver under a particular path on your server::

    upstream pypi {
      server              localhost:8000;
    }

    server {
      location /pypi/ {
          proxy_set_header  X-Forwarded-Host $host:$server_port/pypi;
          proxy_set_header  X-Forwarded-Proto $scheme;
          proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
          proxy_set_header  X-Real-IP $remote_addr;
          proxy_pass        http://pypi;
      }
    }

Supporting HTTPS
~~~~~~~~~~~~~~~~

Using a reverse proxy is the preferred way of getting pypiserver behind
HTTPS. For example, to put pypiserver behind HTTPS on port 443, with
automatic HTTP redirection, using `nginx`::

    upstream pypi {
      server               localhost:8000;
    }

    server {
      listen              80 default_server;
      server_name         _;
      return              301 https://$host$request_uri;
    }

    server {
      listen              443 ssl;
      server_name         pypiserver.example.com;

      ssl_certificate     /etc/star.example.com.crt;
      ssl_certificate_key /etc/star.example.com.key;
      ssl_protocols       TLSv1 TLSv1.1 TLSv1.2;
      ssl_ciphers         HIGH:!aNULL:!MD5;

      location / {
        proxy_set_header  Host $host:$server_port;
        proxy_set_header  X-Forwarded-Proto $scheme;
        proxy_set_header  X-Real-IP $remote_addr;
        proxy_pass        http://pypi;
      }
    }

Please see `nginx's HTTPS docs for more details <http://nginx.org/en/docs/http/configuring_https_servers.html>`_.

Getting and keeping your certificates up-to-date can be simplified using,
for example, using `certbot and letsencrypt <https://www.digitalocean.com/community/tutorials/how-to-secure-nginx-with-let-s-encrypt-on-ubuntu-18-04>`_.

Traefik
~~~~~~~

It is also possible to use `Traefik <https://docs.traefik.io/>`_ to put pypiserver behind HTTPS on port 443, with
automatic HTTP redirection using Docker Compose. Please see the provided `<docker-compose.yml>`_ example for more information.

Utilizing the API
-----------------

In order to enable ad-hoc authentication-providers or to use WSGI-servers
not supported by *bottle* out-of-the-box, you needed to launch ``pypiserver``
via its API.

- The main entry-point for configuring ``pypiserver`` is the `pypiserver:app()
  <https://github.com/pypiserver/pypiserver/blob/master/pypiserver/__init__.py#L116>`_
  function.  This function returns the internal WSGI-app that you my then
  send to any WSGI-server you like.

- To get all ``pypiserver:app()`` keywords and their explanations, read the
  function `pypiserver:default_config()
  <https://github.com/pypiserver/pypiserver/blob/master/pypiserver/__init__.py#L35>`_.

- Finally, to fire-up a WSGI-server with the configured app, invoke
  the ``bottle:run(app, host, port, server)`` function.
  Note that ``pypiserver`` ships with it is own copy of *bottle*; to use it,
  import it like that: ``from pypiserver import bottle``

Using Ad-Hoc Authentication Providers
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The ``auther`` keyword of ``pypiserver:app()`` function maybe set only using
the API. This can be any callable that returns a boolean when passed
the *username* and the *password* for a given request.

For example, to authenticate users based on the ``/etc/passwd`` file under Unix,
you may delegate such decisions to the `python-pam`_ library by following
these steps:

1. Ensure ``python-pam`` module is installed::

    pip install python-pam

2. Create a python-script along these lines::

    $ cat > pypiserver-start.py
    import pypiserver
    from pypiserver import bottle
    import pam
    app = pypiserver.app(root='./packages', auther=pam.authenticate)
    bottle.run(app=app, host='0.0.0.0', port=80, server='auto')

    [Ctrl+ D]

3. Invoke the python-script to start-up ``pypiserver``::

    $ python pypiserver-start.py


.. Note::
   The `python-pam`_ module, requires *read* access to ``/etc/shadow`` file;
   you may add the user under which ``pypiserver`` runs into the *shadow*
   group, with a command like this: ``sudo usermod -a -G shadow pypy-user``.

Use with MicroPython
--------------------
The MicroPython interpreter for embedded devices can install packages with the
module ``upip.py``. The module uses a specialized json-endpoint to retrieve
package information. This endpoint is supported by ``pypiserver``.

It can be tested with the UNIX port of ``micropython``::

    cd micropython
    ports/unix/micropython -m tools.upip install -i http://my-server:8080 -p /tmp/mymodules micropython-foobar

Installing packages from the REPL of an embedded device works in this way:

.. code-block:: python

    import network
    import upip

    sta_if = network.WLAN(network.STA_IF)
    sta_if.active(True)
    sta_if.connect('<your ESSID>', '<your password>')
    upip.index_urls = ["http://my-server:8080"]
    upip.install("micropython-foobar")

Further information on micropython-packaging can be found here: https://docs.micropython.org/en/latest/reference/packages.html

Custom Health Check Endpoint
----------------------------

``pypiserver`` provides a default health endpoint at ``/health``. It always returns
``200 Ok`` if the service is up. Otherwise, it means that the service is not responsive.

In addition, ``pypiserver`` allows users to customize the health endpoint.
Alphanumeric characters, hyphens, forward slashes and underscores are allowed
and the endpoint should not overlap with any existing routes.
Valid examples: ``/healthz``, ``/health/live-1``, ``/api_health``, ``/action/health``

Configure a custom health endpoint by CLI arguments
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Run pypiserver with ``--health-endpoint`` argument::

    pypi-server run --health-endpoint /action/health

Configure a custom health endpoint by script
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

.. code-block:: python

    import pypiserver
    from pypiserver import bottle
    app = pypiserver.app(root="./packages", health_endpoint="/action/health")
    bottle.run(app=app, host="0.0.0.0", port=8080, server="auto")

Try ``curl http://localhost:8080/action/health``

Known Limitations
=================

``pypiserver`` does not implement the full API as seen on PyPI_. It
implements just enough to make ``easy_install``, ``pip install``, and
``search`` work.

The following limitations are known:

- Command ``pypi -U`` that compares uploaded packages with *pypi* to see if
  they are outdated, does not respect a http-proxy environment variable
  (see `#19 <https://github.com/pypiserver/pypiserver/issues/19>`_).
- It accepts documentation uploads but does not save them to
  disk (see `#47 <https://github.com/pypiserver/pypiserver/issues/47>`_ for a
  discussion)
- It does not handle misspelled packages as *pypi-repo* does,
  therefore it is suggested to use it with ``--extra-index-url`` instead
  of ``--index-url`` (see `#38 <https://github.com/pypiserver/pypiserver/issues/38>`_).

Please use Github's `bugtracker <https://github.com/pypiserver/pypiserver/issues>`_
for other bugs you find.


Similar Projects
================

There are lots of other projects, which allow you to run your own
PyPI server. If ``pypiserver`` doesn't work for you, the following are
among the most popular alternatives:
