Looker Cookbook

This is a cookbook for setting up an on-premise install of Looker, the business intelligence software.

Please note, this is not an official Looker product; but made by someone who's a customer|user.

Production Deployment

With the standard set of defaults, this cookbook will install looker very similarly to the official looker documentation. Putting things in the the standard locations (/home/looker/looker...), creating a looker user and group on the machine, and using the self-signed certificate.

You can override the attributes in a cookbook, role, or environment:

node['looker']['looker_user']  = 'looker'
node['looker']['looker_group'] = 'looker'
node['looker']['home_dir']     = '/home/looker/'

Versions

The default version of looker installed is 5.2. If you'd like to specify a different version, you can override the major and minor versions to the specific versions you require. Be advised, this will only work with final versions of looker, and not pre-release versions.

node['looker']['major_version'] = '4'
node['looker']['minor_version'] = '22'

Java JDK

NOTE: Looker 4.2 and greater require a java JDK version of Oracle Java 8 or greater, and, by default, will be part of this installation. You can override the specific java settings in your environment with:

node['java']['jdk_version']    = '8'
node['java']['install_flavor'] = 'oracle'

SSL

If you'd like to have your looker use a proper SSL certificate, you can provide override the [:looker][:use_custom_ssl] attribute to be true, and set the following values:

looker: {
  ssl: {
    aws_access_key_id: 'my-access-key',
    aws_secret_access_key: 'my-secret-key',
    s3_bucket: 'my-bucket',
    certificate_key_path: '/path/to/my-cert.key',
    certificate_path: '/path/to/my-cert.pem',
  }
}

This allows you to point to a given s3 bucket and grab both your certificate .pem file, and it's corresponding .key, and the looker::ssl recipe will setup a java key store, and give those credentials to the looker script. See the attributes/ssl.rb for more details.

Simply include the looker recipe wherever you would like looker to be installed.
