Module Description

This Puppet module manages the resource of Google Spanner. 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-gspanner

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/spanner.admin',
  ],
}

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

Examples

`gspanner_instance_config`

gspanner_instance_config { 'regional-us-central1':
  project    => $project, # e.g. 'my-test-project'
  credential => 'mycred',
}

`gspanner_instance`

gspanner_instance { 'my-spanner':
  display_name => 'My Spanner Instance',
  node_count   => 2,
  labels       => [
    {
      'cost-center' => 'ti-1700004',
    },
  ],
  config       => 'regional-us-central1',
  project      => $project, # e.g. 'my-test-project'
  credential   => 'mycred',
}

`gspanner_database`

gspanner_database { 'webstore':
  ensure           => present,
  extra_statements => [
    'CREATE TABLE customers (
       customer_id INT64 NOT NULL,
       last_name STRING(MAX)
     ) PRIMARY KEY (customer_id)',
  ],
  instance         => 'my-spanner',
  project          => $project, # e.g. 'my-test-project'
  credential       => 'mycred',
}

Classes

Public classes

gspanner_instance_config: A possible configuration for a Cloud Spanner instance. Configurations define the geographic placement of nodes and their replication.
gspanner_instance: An isolated set of Cloud Spanner resources on which databases can be hosted.
gspanner_database: A Cloud Spanner Database which is hosted on a Spanner instance.

About output only properties

Some fields are output-only. It means you cannot set them because they are provided by the Google Cloud Platform. Yet they are still useful to ensure the value the API is assigning (or has assigned in the past) is still the value you expect.

For example in a DNS the name servers are assigned by the Google Cloud DNS service. Checking these values once created is useful to make sure your upstream and/or root DNS masters are in sync. Or if you decide to use the object ID, e.g. the VM unique ID, for billing purposes. If the VM gets deleted and recreated it will have a different ID, despite the name being the same. If that detail is important to you you can verify that the ID of the object did not change by asserting it in the manifest.

Parameters

`gspanner_instance_config`

A possible configuration for a Cloud Spanner instance. Configurations define the geographic placement of nodes and their replication.

Example

gspanner_instance_config { 'regional-us-central1':
  project    => $project, # e.g. 'my-test-project'
  credential => 'mycred',
}

Reference

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

`name`

A unique identifier for the instance configuration. Values are of the form projects/<project>/instanceConfigs/[a-z][-a-z0-9]*

Output-only properties

display_name: Output only. The name of this instance configuration as it appears in UIs.

`gspanner_instance`

An isolated set of Cloud Spanner resources on which databases can be hosted.

Example

gspanner_instance { 'my-spanner':
  display_name => 'My Spanner Instance',
  node_count   => 2,
  labels       => [
    {
      'cost-center' => 'ti-1700004',
    },
  ],
  config       => 'regional-us-central1',
  project      => $project, # e.g. 'my-test-project'
  credential   => 'mycred',
}

Reference

gspanner_instance { 'id-of-resource':
  config       => reference to gspanner_instance_config,
  display_name => string,
  labels       => namevalues,
  name         => string,
  node_count   => integer,
  project      => string,
  credential   => reference to gauth_credential,
}

`name`

A unique identifier for the instance, which cannot be changed after the instance is created. Values are of the form projects/<project>/instances/[a-z][-a-z0-9]*[a-z0-9]. The final segment of the name must be between 6 and 30 characters in length.

`config`

A reference to the instance configuration.

`display_name`

Required. The descriptive name for this instance as it appears in UIs. Must be unique per project and between 4 and 30 characters in length.

`node_count`

The number of nodes allocated to this instance.

`labels`

Cloud Labels are a flexible and lightweight mechanism for organizing cloud resources into groups that reflect a customer's organizational needs and deployment strategies. Cloud Labels can be used to filter collections of resources. They can be used to control how resource metrics are aggregated. And they can be used as arguments to policy management rules (e.g. route, firewall, load balancing, etc.). Label keys must be between 1 and 63 characters long and must conform to the following regular expression: [a-z]([-a-z0-9]*[a-z0-9])?. Label values must be between 0 and 63 characters long and must conform to the regular expression ([a-z]([-a-z0-9]*[a-z0-9])?)?. No more than 64 labels can be associated with a given resource. See https://goo.gl/xmQnxf for more information on and examples of labels. If you plan to use labels in your own code, please note that additional characters may be allowed in the future. And so you are advised to use an internal label representation, such as JSON, which doesn't rely upon specific characters being disallowed. For example, representing labels as the string: name + "" + value would prove problematic if we were to allow "" in a future release. An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.

`gspanner_database`

A Cloud Spanner Database which is hosted on a Spanner instance.

Example

gspanner_database { 'webstore':
  ensure           => present,
  extra_statements => [
    'CREATE TABLE customers (
       customer_id INT64 NOT NULL,
       last_name STRING(MAX)
     ) PRIMARY KEY (customer_id)',
  ],
  instance         => 'my-spanner',
  project          => $project, # e.g. 'my-test-project'
  credential       => 'mycred',
}

Reference

gspanner_database { 'id-of-resource':
  extra_statements => [
    string,
    ...
  ],
  instance         => reference to gspanner_instance,
  name             => string,
  project          => string,
  credential       => reference to gauth_credential,
}

`name`

A unique identifier for the database, which cannot be changed after the instance is created. Values are of the form projects/<project>/instances/[a-z][-a-z0-9]*[a-z0-9]. The final segment of the name must be between 6 and 30 characters in length.

`extra_statements`

An optional list of DDL statements to run inside the newly created database. Statements can create tables, indexes, etc. These statements execute atomically with the creation of the database: if there is an error in any statement, the database is not created.

`instance`

Required. The instance to create the database on.

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.
