Puppetboard
###########
Puppetboard is a web interface to `PuppetDB`_ aiming to replace the reporting
functionality of `Puppet Dashboard`_.
Puppetboard relies on the `pypuppetdb`_ library to fetch data from PuppetDB
and is built with the help of the `Flask`_ microframework.
.. _pypuppetdb: https://pypi.python.org/pypi/pypuppetdb
.. _PuppetDB: http://docs.puppetlabs.com/puppetdb/latest/index.html
.. _Puppet Dashboard: http://docs.puppetlabs.com/dashboard/
.. _Flask: http://flask.pocoo.org
Because this project is powered by Flask we are restricted to:
* Python 2.6
* Python 2.7

Word of caution
===============
Puppetboard is very, very young but it works fairly well.
That being said a lot of the code is very exeprimental, just trying
to figure out what works and what not, what we need to do different
and what features we need on the PuppetDB side of things.
As such you should be at least comfortable handling a few errors
this might throw at you.
Installation
============
Puppetboard is now packaged and available on PyPi.
Production
----------
To install it simply issue the following command:
.. code-block:: bash
$ pip install puppetboard
This will install Puppetboard and take care of the dependencies. If you
do this Puppetboard will be installed in the so called site-packages or
dist-packages of your Python distribution.
The complete path on Debian systems would be:
``/usr/local/lib/python2.X/lib/dist-packages/puppetboard``.
You will need this path in order to configure your HTTPD and WSGI-capable
application server.
Packages
^^^^^^^^
Native packages for your operating system will be provided in the near future.

Development
-----------
If you wish to hack on Puppetboard you should fork/clone the Github repository
and then install the requirements through:
.. code-block:: bash
$ pip install -r requirements.txt
You're advised to do this inside a virtualenv specifically created to work on
Puppetboard as to not pollute your global Python installation.
Configuration
=============
The following instructions will help you configure Puppetboard and your HTTPD.
Puppet
------
Puppetboard is built completely around PuppetDB which means your environment
needs to be configured `to do that`_.
In order to get the reports to show up in Puppetboard you need to configure
your environment to store those reports in PuppetDB. Have a look at
`the documentation`_ about this, specifically the *Enabling report storage*
section.
.. _to do that: https://docs.puppetlabs.com/puppetdb/latest/connect_puppet_master.html#step-2-edit-config-files
.. _the documentation: https://docs.puppetlabs.com/puppetdb/latest/connect_puppet_master.html#edit-puppetconf
Settings
--------
Puppetboard will look for a file pointed at by the ``PUPPETBOARD_SETTINGS``
environment variable. The file has to be identical to ``default_settings.py``
but should only override the settings you need changed.
You can grab a copy of ``default_settings.py`` from the path where pip
installed Puppetboard to or by looking in the source checkout.
If you run PuppetDB and Puppetboard on the same machine the default settings
provided will be enough to get you started and you won't need a custom
settings file.
Assuming your webserver and PuppetDB machine are not identical you will at
least have to change the following settings:
* ``PUPPETDB_HOST``
* ``PUPPETDB_PORT``
By default PuppetDB requires SSL to be used when a non-local client wants to
connect. Therefor you'll also have to supply the following settings:
* ``PUPPETDB_KEY = /path/to/private/keyfile.pem``
* ``PUPPETDB_CERT = /path/to/public/keyfile.crt``
For information about how to generate the correct keys please refer to the
`pypuppetdb documentation`_.
Other settings that might be interesting:
* ``PUPPETDB_TIMEOUT``: Defaults to 20 seconds but you might need to increase
this value. It depends on how big the results are when querying PuppetDB.
This behaviour will change in a future release when pagination will be
introduced.
* ``UNRESPONSIVE_HOURS``: The amount of hours since the last check-in after
which a node is considered unresponsive.
* ``LOGLEVEL``: A string representing the loglevel. It defaults to ``'info'``
but can be changed to ``'warning'`` or ``'critical'`` for less verbose
logging or ``'debug'`` for more information.
* ``ENABLE_QUERY``: Defaults to ``True`` causing a Query tab to show up in the
web interface allowing users to write and execute arbitrary queries against
a set of endpoints in PuppetDB. Change this to ``False`` to disable this.
.. _pypuppetdb documentation: http://pypuppetdb.readthedocs.org/en/v0.1.0/quickstart.html#ssl
Development
-----------
You can run it in development mode by simply executing:
.. code-block:: bash
$ python dev.py
Use ``PUPPETBOARD_SETTINGS`` to change the different settings or patch
``default_settings.py`` directly. Take care not to include your local changes on
that file when submitting patches for Puppetboard. Place a settings.py file
inside the base directory of the git repository that will be used, if the
environment variable is not set.
Production
----------
To run Puppetboard in production we provide instructions for the following
scenarios:
* Apache + mod_wsgi
* Apache + mod_passenger
* uwsgi + nginx
If you deploy Puppetboard through a different setup we'd welcome a pull
request that adds the instructions to this section.
Apache + mod_wsgi
^^^^^^^^^^^^^^^^^
First we need to create the necessary directories:
.. code-block:: bash
$ mkdir -p /var/www/puppetboard
$ chown www-data:www-data /var/www/puppetboard
Copy Puppetboard's ``default_settings.py`` to the newly created puppetboard
directory and name the file ``settings.py``. This file will be available
at the path Puppetboard was installed, for example:
``/usr/local/lib/python2.X/lib/dist-packages/puppetboard/default_settings.py``.
Change the settings that need changing to match your environment and delete
or comment with a ``#`` the rest of the entries.
If you don't need to change any settings you can skip the creation of the
``settings.py`` file entirely.
Now create a ``wsgi.py`` with the following content in the newly created
puppetboard directory:
.. code-block:: python
from __future__ import absolute_import
import os
# Needed if a settings.py file exists
os.environ['PUPPETBOARD_SETTINGS'] = '/var/www/puppetboard/settings.py'
from puppetboard.app import app as application
Make sure this file is owned by the user and group the webserver runs as.
The last thing we need to do is configure Apache:
.. code-block:: apache
<VirtualHost *:80>
ServerName puppetboard.example.tld
WSGIDaemonProcess puppetboard user=www-data group=www-data threads=5
WSGIScriptAlias / /var/www/puppetboard/wsgi.py
ErrorLog /var/log/apache2/puppetboard.error.log
CustomLog /var/log/apache2/puppetboard.access.log combined
Alias /static /usr/local/lib/python2.X/dist-packages/puppetboard/static
<Directory /usr/local/lib/python2.X/dist-packages/puppetboard>
WSGIProcessGroup puppetboard
WSGIApplicationGroup %{GLOBAL}
Order deny,allow
Allow from all
</Directory>
</VirtualHost>
Note the directory path, it's the path to where pip installed Puppetboard. We
also alias the ``/static`` path so that Apache will serve the static files
like the included CSS and Javascript.
Apache + mod_passenger
^^^^^^^^^^^^^^^^^^^^^^
It is possible to run Python applications through Passenger. Passenger has
supported this since version 3 but it's considered experimental. Since the
release of Passenger 4 it's a 'core' feature of the product.
Performance wise it also leaves something to be desired compared to the
mod_wsgi powered solution. Application start up is noticeably slower and
loading pages takes a fraction longer.
First we need to create the necessary directories:
.. code-block:: bash
$ mkdir -p /var/www/puppetboard/{tmp,public}
$ chown -R www-data:www-data /var/www/puppetboard
Copy Puppetboard's ``default_settings.py`` to the newly created puppetboard
directory and name the file ``settings.py``. This file will be available
at the path Puppetboard was installed, for example:
``/usr/local/lib/python2.X/lib/dist-packages/puppetboard/default_settings.py``.
Change the settings that need changing to match your environment and delete
or comment with a ``#`` the rest of the entries.
If you don't need to change any settings you can skip the creation of the
``settings.py`` file entirely.
Now create a ``passenger_wsgi.py`` with the following content in the newly
created puppetboard directory:
.. code-block:: python
from __future__ import absolute_import
import os
import logging
logging.basicConfig(filename=/path/to/file/for/logging, level=logging.INFO)
# Needed if a settings.py file exists
os.environ['PUPPETBOARD_SETTINGS'] = '/var/www/puppetboard/settings.py'
try:
from puppetboard.app import app as application
except Exception, inst:
logging.exception("Error: %s", str(type(inst)))
Unfortunately due to the way Passenger works we also need to configure logging
inside ``passenger_wsgi.py`` else application start up issues won't be logged.
This means that even though ``LOGLEVEL`` might be set in your ``settings.py``
this setting will take precedence over it.
Now the only thing left to do is configure Apache:
.. code-block:: apache
<VirtualHost *:80>
ServerName puppetboard.example.tld
DocumentRoot /var/www/puppetboard/public
ErrorLog /var/log/apache2/puppetboard.error.log
CustomLog /var/log/apache2/puppetboard.access.log combined
RackAutoDetect On
Alias /static /usr/local/lib/python2.X/dist-packages/puppetboard/static
</VirtualHost>
Note the ``/static`` alias path, it's the path to where pip installed
Puppetboard. This is needed so that Apache will serve the static files like
the included CSS and Javascript.
nginx + uwsgi
^^^^^^^^^^^^^
A common Python deployment scenario is to use the uwsgi application server
(which can also serve rails/rack, PHP, Perl and other applications) and proxy
to it through something like nginx or perhaps even HAProxy.
uwsgi has a feature that every instance can run as its own user. In this
example we'll use the ``www-data`` user but you can create a separate user
solely for running Puppetboard and use that instead.
First we need to create the necessary directories:
.. code-block:: bash
$ mkdir -p /var/www/puppetboard
$ chown www-data:www-data /var/www/puppetboard
Copy Puppetboard's ``default_settings.py`` to the newly created puppetboard
directory and name the file ``settings.py``. This file will be available
at the path Puppetboard was installed, for example:
``/usr/local/lib/python2.X/lib/dist-packages/puppetboard/default_settings.py``.
Change the settings that need changing to match your environment and delete
or comment with a ``#`` the rest of the entries.
If you don't need to change any settings you can skip the creation of the
``settings.py`` file entirely.
Now create a ``wsgi.py`` with the following content in the newly created
puppetboard directory:
.. code-block:: python
from __future__ import absolute_import
import os
# Needed if a settings.py file exists
os.environ['PUPPETBOARD_SETTINGS'] = '/var/www/puppetboard/settings.py'
from puppetboard.app import app as application
Make sure this file is owned by the user and group the uwsgi instance will run
as.
Now we need to start uwsgi:
.. code-block:: bash
$ uwsgi --http :9090 --wsgi-file /var/www/puppetboard/wsgi.py
Feel free to change the port to something other than ``9090``.
The last thing we need to do is configure nginx to proxy the requests:
.. code-block:: nginx
upstream puppetboard {
server 127.0.0.1:9090;
}
server {
listen 80;
server_name puppetboard.example.tld;
charset utf-8;
location /static {
alias /usr/local/lib/python2.X/dist-packages/puppetboard/static;
}
location / {
uwsgi_pass puppetboard;
include /path/to/uwsgi_params/probably/etc/nginx/uwsgi_params;
}
}
If all went well you should now be able to access to Puppetboard. Note the
``/static`` location block to make nginx serve static files like the included
CSS and Javascript.
Because nginx natively supports the uwsgi protocol we use ``uwsgi_pass``
instead of the traditional ``proxy_pass``.
Security
--------
If you wish to make users authenticate before getting access to Puppetboard
you can use one of the following configuration snippets.
Apache
^^^^^^
Inside the ``VirtualHost``:
.. code-block:: apache
<Location "/">
AuthType Basic
AuthName "Puppetboard"
Require valid-user
AuthBasicProvider file
AuthUserFile /path/to/a/file.htpasswd
</Location>
nginx
^^^^^
Inside the ``location / {}`` block that has the ``uwsgi_pass`` directive:
.. code-block:: nginx
auth_basic "Puppetboard";
auth_basic_user_file /path/to/a/file.htpasswd;
