Module Description

This Puppet module manages the resource of Google Cloud Pub/Sub. You can manage its resources using standard Puppet DSL and the module will, under the hood, ensure the state described will be reflected in the Google Cloud Platform resources.

Setup

To install this module on your Puppet Master (or Puppet Client/Agent), use the Puppet module installer:

puppet module install google-gpubsub

Optionally you can install support to all Google Cloud Platform products at once by installing our "bundle" google-cloud module:

puppet module install google-cloud

Since this module depends on the googleauth and google-api-client gems, you will also need to install those, with

/opt/puppetlabs/puppet/bin/gem install googleauth google-api-client

If you prefer, you could also add the following to your puppet manifest:

    package { [
            'googleauth',
            'google-api-client',
        ]:
            ensure   => present,
            provider => puppet_gem,
    }

Usage

Credentials

All Google Cloud Platform modules use an unified authentication mechanism, provided by the google-gauth module. Don't worry, it is automatically installed when you install this module.

gauth_credential { 'mycred':
  path     => $cred_path, # e.g. '/home/nelsonjr/my_account.json'
  provider => serviceaccount,
  scopes   => [
    'https://www.googleapis.com/auth/pubsub',
  ],
}

Please refer to the google-gauth module for further requirements, i.e. required gems.

Examples

gpubsub_topic

gpubsub_topic { 'conversation-1':
  ensure     => present,
  project    => $project, # e.g. 'my-test-project'
  credential => 'mycred',
}

gpubsub_subscription

gpubsub_subscription { 'subscription-1':
  ensure               => present,
  topic                => 'conversation-1',
  push_config          => {
    push_endpoint => 'https://myapp.graphite.cloudnativeapp.com/webhook/sub1',
  },
  ack_deadline_seconds => 300,
  project              => $project, # e.g. 'my-test-project'
  credential           => 'mycred',
}

Classes

Public classes

  • gpubsub_topic: A named resource to which messages are sent by publishers.
  • gpubsub_subscription: A named resource representing the stream of messages from a single, specific topic, to be delivered to the subscribing application.

Parameters

gpubsub_topic

A named resource to which messages are sent by publishers.

Example

gpubsub_topic { 'conversation-1':
  ensure     => present,
  project    => $project, # e.g. 'my-test-project'
  credential => 'mycred',
}

Reference

gpubsub_topic { 'id-of-resource':
  name       => string,
  project    => string,
  credential => reference to gauth_credential,
}
name

Name of the topic.

gpubsub_subscription

A named resource representing the stream of messages from a single, specific topic, to be delivered to the subscribing application.

Example

gpubsub_subscription { 'subscription-1':
  ensure               => present,
  topic                => 'conversation-1',
  push_config          => {
    push_endpoint => 'https://myapp.graphite.cloudnativeapp.com/webhook/sub1',
  },
  ack_deadline_seconds => 300,
  project              => $project, # e.g. 'my-test-project'
  credential           => 'mycred',
}

Reference

gpubsub_subscription { 'id-of-resource':
  ack_deadline_seconds => integer,
  name                 => string,
  push_config          => {
    push_endpoint => string,
  },
  topic                => reference to gpubsub_topic,
  project              => string,
  credential           => reference to gauth_credential,
}
name

Name of the subscription.

topic

A reference to a Topic resource.

push_config

If push delivery is used with this subscription, this field is used to configure it. An empty pushConfig signifies that the subscriber will pull and ack messages using API methods.

push_config/push_endpoint

A URL locating the endpoint to which messages should be pushed. For example, a Webhook endpoint might use "https://example.com/push".

ack_deadline_seconds

This value is the maximum time after a subscriber receives a message before the subscriber should acknowledge the message. After message delivery but before the ack deadline expires and before the message is acknowledged, it is an outstanding message and will not be delivered again during that time (on a best-effort basis). For pull subscriptions, this value is used as the initial value for the ack deadline. To override this value for a given message, call subscriptions.modifyAckDeadline with the corresponding ackId if using pull. The minimum custom deadline you can specify is 10 seconds. The maximum custom deadline you can specify is 600 seconds (10 minutes). If this parameter is 0, a default value of 10 seconds is used. For push delivery, this value is also used to set the request timeout for the call to the push endpoint. If the subscriber never acknowledges the message, the Pub/Sub system will eventually redeliver the message.

Bolt Tasks

This task takes inputs as JSON from standard input.

Development

Automatically Generated Files

Some files in this package are automatically generated by Magic Modules.

We use a code compiler to produce this module in order to avoid repetitive tasks and improve code quality. This means all Google Cloud Platform Puppet modules use the same underlying authentication, logic, test generation, style checks, etc.

Learn more about the way to change autogenerated files by reading the CONTRIBUTING.md file.

Contributing

Contributions to this library are always welcome and highly encouraged.

See CONTRIBUTING.md for more information on how to get started.

Running tests

This project contains tests for rspec, rspec-puppet and rubocop to verify functionality. For detailed information on using these tools, please see their respective documentation.

Testing quickstart: Ruby > 2.0.0

gem install bundler
bundle install

bundle exec rubocop

Debugging Tests

In case you need to debug tests in this module you can set the following variables to increase verbose output:

Variable Side Effect
PUPPET_HTTP_VERBOSE=1 Prints network access information by Puppet provier.
