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.

At the current time of writing, Puppetboard supports the following Python versions:

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 experimental, 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

Puppet module

There is a Puppet module by Spencer Krum that takes care of installing Puppetboard for you.

You can install it with:

puppet module install nibalizer-puppetboard

Manual

To install it simply issue the following command:

$ 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 and Ubuntu systems would be /usr/local/lib/pythonX.Y/lib/dist-packages/puppetboard and on Fedora would be /usr/lib/pythonX.Y/lib/site-packages/puppetboard

where X and Y are replaced by your major and minor python versions.

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.

OS	Status
Debian 6/Squeeze	planned	Requires Backports
Debian 7/Wheezy	planned
Ubuntu 13.04	planned
Ubuntu 13.10	planned
CentOS/RHEL 5	n/a	Python 2.4
CentOS/RHEL 6	planned
OpenSuSE 12/13	available	Maintained on OpenSuSE Build Service
SuSE LE 11 SP3	available	Maintained on OpenSuSE Build Service
ArchLinux	available	Maintained by Niels Abspoel
OpenBSD	available	Maintained by Jasper Lievisse Adriaanse

Development

If you wish to hack on Puppetboard you should fork/clone the Github repository and then install the requirements through:

$ 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.

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_SSL_VERIFY = /path/to/ca/keyfile.pem
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:

SECRET_KEY: Refer to Flask documentation, section sessions: How to generate good secret keys, to set the value.
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.

Puppet Enterprise

Puppet Enterprise maintains a certificate white-list for which certificates are allowed to access data from PuppetDB. This whitelist is maintained in /etc/puppetlabs/puppetdb/certificate-whitelist and you have to add the certificate name to that file.

Afterwards you'll need to restart pe-puppetdb and you should be able to query PuppetDB freely now.

Development

You can run it in development mode by simply executing:

$ 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
nginx + uwsgi
nginx + gunicorn

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:

$ mkdir -p /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/pythonX.Y/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:

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 readable by the user the webserver runs as.

The last thing we need to do is configure Apache.

Here is a sample configuration for Debian and Ubuntu:

<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/pythonX.Y/dist-packages/puppetboard/static
    <Directory /usr/lib/python2.X/dist-packages/puppetboard/static>
        Satisfy Any
        Allow from all
    </Directory>

    <Directory /usr/local/lib/pythonX.Y/dist-packages/puppetboard>
        WSGIProcessGroup puppetboard
        WSGIApplicationGroup %{GLOBAL}
        Order deny,allow
        Allow from all
    </Directory>
</VirtualHost>

Here is a sample configuration for Fedora:

<VirtualHost *:80>
    ServerName puppetboard.example.tld
    WSGIDaemonProcess puppetboard user=apache group=apache threads=5
    WSGIScriptAlias / /var/www/puppetboard/wsgi.py
    ErrorLog /var/log/httpd/puppetboard.error.log
    CustomLog /var/log/httpd/puppetboard.access.log combined

    Alias /static /usr/local/lib/pythonX.Y/site-packages/puppetboard/static
    <Directory /usr/lib/python2.X/site-packages/puppetboard/static>
        Satisfy Any
        Allow from all
    </Directory>

    <Directory /usr/lib/pythonX.Y/site-packages/puppetboard>
        WSGIProcessGroup puppetboard
        WSGIApplicationGroup %{GLOBAL}
        Require all granted
    </Directory>
</VirtualHost>

Note the directory path, it's the path to where pip installed Puppetboard; X.Y must be replaced with your python version. 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:

$ mkdir -p /var/www/puppetboard/{tmp,public}

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:

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:

<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/pythonX.Y/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:

$ mkdir -p /var/www/puppetboard

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:

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:

$ uwsgi --socket :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:

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/pythonX.Y/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.

nginx + gunicorn

You can use gunicorn instead of uwsgi if you prefer, the process doesn't differ too much. As we can't use uwsgi_pass with gunicorn, the nginx configuration file is going to differ a bit:

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/pythonX.Y/dist-packages/puppetboard/static;
    }

    location / {
        add_header Access-Control-Allow-Origin *;
        proxy_pass_header Server;
        proxy_set_header Host $http_host;
        proxy_redirect off;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Scheme $scheme;
        proxy_connect_timeout 10;
        proxy_read_timeout 10;
        proxy_pass http://127.0.0.1:9090;
    }
}

Now, for running it with gunicorn:

$ cd /usr/local/lib/pythonX.Y/dist-packages/puppetboard
$ gunicorn -b 127.0.0.1:9090 puppetboard.app:app

As we may want to serve in the background, and we need PUPPETBOARD_SETTINGS as an environment variable, is recommendable to run this under supervisor. An example supervisor config with basic settings is the following:

[program:puppetboard]
command=gunicorn -b 127.0.0.1:9090 puppetboard.app:app
user=www-data
stdout_logfile=/var/log/supervisor/puppetboard/puppetboard.out
stderr_logfile=/var/log/supervisor/puppetboard/puppetboard.err
environment=PUPPETBOARD_SETTINGS="/var/www/puppetboard/settings.py"

For newer systems with systemd (for example CentOS7), you can use the following service file (/usr/lib/systemd/system/gunicorn@.service):

[Unit]
Description=gunicorn daemon for %i
After=network.target

[Service]
ExecStart=/usr/bin/gunicorn --config /etc/sysconfig/gunicorn/%i.conf %i
ExecReload=/bin/kill -s HUP $MAINPID
PrivateTmp=true
User=gunicorn
Group=gunicorn

And the corresponding gunicorn config (/etc/sysconfig/gunicorn/puppetboard.app\:app.conf):

import multiprocessing

bind    = '127.0.0.1:9090'
workers = multiprocessing.cpu_count() * 2 + 1
chdir   = '/usr/lib/python2.7/site-packages/puppetboard'
raw_env = ['PUPPETBOARD_SETTINGS=/var/www/puppetboard/settings.py', 'http_proxy=']

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:

<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:

auth_basic "Puppetboard";
auth_basic_user_file /path/to/a/file.htpasswd;

Getting Help

This project is still very new so it's not inconceivable you'll run into issues.

For bug reports you can file an issue. If you need help with something feel free to hit up @daenney by e-mail or find him on IRC. He can usually be found on IRCnet and Freenode and idles in #puppet.

There's now also the #puppetboard channel on Freenode where we hang out and answer questions related to pypuppetdb and Puppetboard.
