Puppetboard

PyPI Version PyPI Downloads Tests Status codecov By Voxpupuli

Puppetboard is a web interface to PuppetDB aiming to replace the reporting functionality of Puppet Enterprise console (previously: Puppet Dashboard) for the open source Puppet.

Overview

See more screenshots here.

Table of Contents

Requirements

  • PuppetDB v. 5.2-8.*
    • (Note: PuppetDB 8.1.0 is not supported because of this bug. Please update to 8.1.1+.)
  • Python 3.8-3.11 or Docker

Installation

Puppetboard is packaged and available on PyPI.

With Puppet module

There is a Puppet module originally written by Spencer Krum and currently maintained by Voxpupuli that takes care of installing the Puppetboard for you.

To see how to get it working with RedHat/Centos 7 check out these docs.

Using Docker

We provide an official Docker image in the GitHub Container Registry.

You must provide a secret key! Generate one for example by running ruby -e "require 'securerandom'; puts SecureRandom.hex(32)".

You can run the app on your PuppetDB host with this command:

docker run -it \
  -e PUPPETDB_HOST=localhost \
  -e PUPPETDB_PORT=8080 \
  -e SECRET_KEY=XXXXXXXX \
  --net=host \
  ghcr.io/voxpupuli/puppetboard

Optionally you can set PUPPETBOARD_URL_PREFIX env variable to a value like /puppetboard to run the app under a URL prefix.

You can use the following Puppet Code to have Puppetboard managed by Puppet:

include docker

docker::image { 'ghcr.io/voxpupuli/puppetboard': }

docker::run { 'puppetboard':
  image => 'ghcr.io/voxpupuli/puppetboard',
  env   => [
    'PUPPETDB_HOST=127.0.0.1',
    'PUPPETDB_PORT=8080',
    'PUPPETBOARD_PORT=8088',
    'SECRET_KEY=XXXXXXXX',
  ],
  net   => 'host',
}

If you want to have all features enabled, you must use SSL talking to PuppetDB:

file { '/etc/puppetboard':
  ensure => directory,
}
file { '/etc/puppetboard/key.pem':
  ensure => file,
  mode   => '0644',
  source => "/etc/puppetlabs/puppet/ssl/private_keys/${facts['networking']['fqdn']}.pem",
}
file { '/etc/puppetboard/cert.pem':
  ensure => file,
  mode   => '0644',
  source => "/etc/puppetlabs/puppet/ssl/certs/${facts['networking']['fqdn']}.pem",
}

include docker

docker::image { 'ghcr.io/voxpupuli/puppetboard': }

docker::run { 'puppetboard':
  image   => 'ghcr.io/voxpupuli/puppetboard',
  volumes => ['/etc/puppetboard:/etc/puppetboard:ro'],
  env     => [
    'PUPPETDB_HOST=puppet', # this must be the certname or DNS_ALT_NAME of the PuppetDB host
    'PUPPETDB_PORT=8081',
    'PUPPETBOARD_PORT=8080',
    'ENABLE_CATALOG=true',
    'PUPPETDB_SSL_VERIFY=false',
    'PUPPETDB_KEY=/etc/puppetboard/key.pem',
    'PUPPETDB_CERT=/etc/puppetboard/cert.pem',
    'SECRET_KEY=XXXXXXXX',
    'DEFAULT_ENVIRONMENT=*',
  ],
  net     => 'host',
}

Within an air gapped environment you want to load all content from your local puppetboard web service. Add: 'OFFLINE_MODE=true', to the env parameter list of the docker::run Puppet type.

We also provide the Dockerfile, so you can build the image yourself:

docker build -t puppetboard .

From a package

Actively maintained packages:

Manually

You can also install the package from PyPI and configure a WSGI-capable application server to serve it.

We recommend using virtualenv to provide a separate environment for the app.

virtualenv -p python3 venv
. venv/bin/activate
pip install puppetboard

Please see an article about more deployment setups here.

Configuration

Puppet agents

The default value of usecacheonfailure = true configuration setting for Puppet agents causes Puppet runs to always succeed, event if there are catalog compilation failures f.e. because of a syntax error in your code. This is because in such cases with this setting Puppet will just use a cached working catalog and report the run to PuppetDB as successful. (Although with an error visible in the Puppet run log.)

Therefore, to show the nodes with a catalog compilation as failed in Puppetboard you need to set usecacheonfailure = false in your nodes' puppet.conf.

PuppetDB

Of course you need to configure your Puppet Server to store the Puppet run reports in PuppetDB. If you haven't done that already please follow the PuppetDB documentation about this.

If you run Puppetboard on a different host than PuppetDB then you may want to configure the certificate allow-list for which certificates are allowed to access data from PuppetDB. Please read more about this feature in the PuppetDB documentation here.

App 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.

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. Therefore you'll also have to supply the following settings:

  • PUPPETDB_SSL_VERIFY = True
  • PUPPETDB_KEY = /path/to/private/keyfile.pem
  • PUPPETDB_CERT = /path/to/public/keyfile.crt

When using the Puppetboard Docker image, you may also pass Puppetboard it's certificate contents via these environment variables, either as a multiline string or pre-base64 encoded. This can be useful where the certificate is stored in a secrets store i.e. AWS SSM Parameter Store.

PUPPETDB_CERT="-----BEGIN CERTIFICATE-----
...
-----END CERTIFICATE-----"
PUPPETDB_CERT=LS0tLS1CRUdJTiBSU0EgUFJJVkFURSBLRVktLS0tLQouLi4KLS0tLS1FTkQgQ0VSVElGSUNBVEUtLS0tLQ==

For information about how to generate the correct keys please refer to the pypuppetdb documentation. Alternatively it is possible to explicitly specify the protocol to be used setting the PUPPETDB_PROTO variable.

Other settings that might be interesting, in no particular order:

  • SECRET_KEY: set this to a long string, the same for each application replica, and keep it secret. Refer to Flask documentation, section "How to generate good secret keys" for more info. Cannot be an empty string, which is the default.
  • FAVORITE_ENVS: an ordered list of Puppet environment names that will be shown immediately after "All Environments" and before other environments (which are sorted by name) in the dropdown for choosing the environment shown in the top-right of the UI. Environments listed here that do not really exist in your deployment are silently ignored.
  • SHOW_ERROR_AS: friendly or raw. The former makes Puppet run errors in Report and Failures views shown in a modified, (arguably) more user-friendly form. The latter shows them as they are. Defaults to friendly.
  • CODE_PREFIX_TO_REMOVE: what code path that should be shortened in "Friendly errors" to "…" for readability. A regexp. Defaults to /etc/puppetlabs/code/environments(/.*?/modules)?.
  • 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. See ENABLED_QUERY_ENDPOINTS to fine-tune which endpoints are allowed.
  • ENABLED_QUERY_ENDPOINTS: If ENABLE_QUERY is True, allow to fine tune the endpoints of PuppetDB APIs that can be queried. It must be a list of strings of PuppetDB endpoints for which the query is enabled. See the QUERY_ENDPOINTS constant in the puppetboard.app module for a list of the available endpoints.
  • GRAPH_TYPE: Specify the type of graph to display. Default is pie, other good option is donut. Other choices can be found here: C3.js documentation
  • GRAPH_FACTS: A list of fact names to tell PuppetBoard to generate a pie-chart on the fact page. With some fact values being unique per node, like ipaddress, uuid, and serial number, as well as structured facts it was no longer feasible to generate a graph for everything.
  • INVENTORY_FACTS: A list of tuples that serve as the column header and the fact name to search for to create the inventory page. If a fact is not found for a node then undef is printed.
  • INVENTORY_FACT_TEMPLATES: A mapping between fact name and jinja template to customize display
  • ENABLE_CATALOG: If set to True allows the user to view a node's latest catalog. This includes all managed resources, their file-system locations and their relationships, if available. Defaults to False.
  • REFRESH_RATE: Defaults to 30 the number of seconds to wait until the index page is automatically refreshed.
  • DEFAULT_ENVIRONMENT: Defaults to 'production', as the name suggests, load all information filtered by this environment value.
  • REPORTS_COUNT: Defaults to 10 the limit of the number of reports to load on the node or any reports page.
  • OFFLINE_MODE: If set to True load static assets (jquery, semantic-ui, etc) from the local web server instead of a CDN. Defaults to False.
  • DAILY_REPORTS_CHART_ENABLED: Enable the use of daily chart graphs when looking at dashboard and node view.
  • DAILY_REPORTS_CHART_DAYS: Number of days to show history for on the daily report graphs.
  • DISPLAYED_METRICS: Metrics to show when displaying node summary. Example: 'resources.total', 'events.noop'.
  • TABLE_COUNT_SELECTOR: Configure the dropdown to limit number of hosts to show per page.
  • LITTLE_TABLE_COUNT: Default number of reports to show when when looking at a node.
  • NORMAL_TABLE_COUNT: Default number of nodes to show when displaying reports and catalog nodes.
  • LOCALISE_TIMESTAMP: If set to True then timestamps are shown using your browser's timezone. Otherwise UTC is used. Defaults to True.
  • WITH_EVENT_NUMBERS: If set to True then Overview and Nodes list shows exact number of changed resources in the last report. Otherwise shows only 'some' string if there are resources with given status. Setting this to False gives performance benefits, especially in big Puppet environments (more than few hundreds of nodes). Defaults to True.
  • ENABLE_CLASS: If set to True allows the user to view the number of resource events (number of changed resources in the last report) grouped by class. The resource events are grouped by their status ('failure', 'success', 'noop').
  • CLASS_EVENTS_STATUS_COLUMNS: A mapping between the status of the resource events and the name of the columns of the table to display.
  • CACHE_TYPE: Specifies which type of caching object to use when SCHEDULER_ENABLED is set to True. The cache is used for the classes view (ENABLE_CLASS is set to True) which requires parsing the events of all the latest reports to group them by Puppet class. If the last report is present in the cache, we do not parse the events, which avoids unnecessary processing. If you configure more than one worker, you must use a shared backend (e.g. MemcachedCache) to allow the sharing of the cache between the processes. Indeed, the SimpleCache type does not allow sharing the cache between processes, it uses the process memory to store the cache. Defaults to SimpleCache.
  • CACHE_DEFAULT_TIMEOUT: Cache lifetime in second. Defaults to 3600.
  • SCHEDULER_ENABLED: If set to True then a scheduler instance is created in order to execute scheduled jobs. Defaults to False.
  • SCHEDULER_JOBS: List of the scheduled jobs to trigger within a worker. A job can for example be used to compute a result to be cached. This is the case for the classes view which uses a job to pre-compute at regular intervals the results to be displayed. Each scheduled job must contain the following fields: id, func, trigger, seconds.
  • SCHEDULER_LOCK_BIND_PORT: Specifies an available port that allows a single worker to listen on it. This allows to configure scheduled jobs in a single worker. Defaults to 49100.

Development

Puppetboard relies on the pypuppetdb library to fetch data from PuppetDB and is built with the help of the Flask microframework.

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

pip install --upgrade wheel setuptools
python setup.py develop
pip install --upgrade -r requirements-test.txt
mypy --install-types --non-interactive puppetboard/ test/

You're advised to do this inside a virtualenv specifically created to work on Puppetboard as to not pollute your global Python installation.

You can run the tests with:

pytest --cov=. --cov-report=xml --strict-markers --mypy puppetboard test
pylint --errors-only puppetboard test

You can run the app it in development mode by simply executing:

flask run

You can specify listening host and port with environment variables or command line otions:

export FLASK_RUN_HOST=0.0.0.0
export FLASK_RUN_PORT=8000

flask run

or

flask run --host '0.0.0.0' --port '8000'

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.

We welcome contributions to this project. However, there are a few ground rules contributors should be aware of.
