grafana2

Description

Brand new cookbook for the new Grafana 2.0 release. See: http://grafana.org/blog/2015/04/20/Grafana-2-Released.html

We used RDS/MySQL for data and sessions. Will add options for other setups soon.

Manually create a MySQL RDS instance and update attributes/default.rb Manually create the sessions table in mysql: yum install mysql

CREATE TABLE `session` (
    `key`       CHAR(16) NOT NULL,
    `data`      BLOB,
    `expiry`    INT(11) UNSIGNED NOT NULL,
    PRIMARY KEY (`key`)
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

...

Usage

You must change the attributes for domain and database host, user, password.

Add 'recipe[grafana2::default]' to your node's run-list.

To use this cookbook in another recipe, add a dependency on it to your cookbook's metadata.rb:

depends 'grafana2', '~> 0.0'

Then include it in one of your recipes:

include_recipe 'grafana2::default'

(the ~~> syntax will pull in the latest version in the 0.x series but not any version in 1.x. As the cookbook you depend on is updated, you will have to change this to '~~> 1.0' as appropriate.)

Recipes

default

The default recipe will call install, config, and service definitions.

Attributes

The attributes defined by this recipe are organized under the node['grafana2'] namespace.

Attribute	Description	Type	Default
domain	Used in setting root URL	String
db_host	IP or hostname for database	String

Development

The first time you check out this cookbook, run

bundle --binstubs

to download and install the development tools.

Testing

Three forms of cookbook testing are available:

Style Checks

bin/rake style

Will run foodcritic (cookbook style) and tailor (ruby style/syntax) checks. These tests must pass before the cookbook can progress through the CI pipeline.

Unit Tests

bin/rake spec

Will run ChefSpec tests. It is a good idea to ensure that these tests pass before committing changes to git.

Unit Test Coverage

bin/rake coverage

Will run the ChefSpec tests and report on test coverage. It is a good idea to make sure that every Chef resource you declare is covered by a unit test.

Automated Testing with Guard

bin/guard

Will run foodcritic, tailor, rubocop (if enabled) and chefspec tests automatically when the associated files change. If a chefspec test fails, it will drop you into a pry session in the context of the failure to explore the state of the run.

To disable the pry-rescue behavior, define the environment variable DISABLE_PRY_RESCUE before running guard:

DISABLE_PRY_RESCUE=1 bin/guard

Integration Tests

bin/rake kitchen:all

Will run the test kitchen integration tests. These tests use Vagrant and Virtualbox, which must be installed for the tests to execute.

These are only available for cookbooks that target Unix-like systems. Support for Windows targets is expected by the end of 2014.

By default, these tests run against Centos 6.6 and Ubuntu 12.04 images, but this can be changed in the file .kitchen.yml.

After converging in a virtual machine, ServerSpec tests are executed. This skeleton comes with a very basic ServerSpec test; refer to http://serverspec.org for detail on how to create tests.

Using Berkshelf for dependencies

In order for Berkshelf to access both the public supermarket and the Nordstrom private supermarket, we need to use a forked copy of the berkshelf and berkshelf-api-client gems.

To ensure that you use the forked versions rather than the ones that come with ChefDK, ensure that you always run

bundle exec berks install

rather than just

berks install

Customization

Certain files are overwritten when the cookbook generator is run on top of an existing cookbook, including

Gemfile
Berksfile
Rakefile
Guardfile

To add local customizations to these files, place them in separate files in subdirectories of lib, as described below:

Rakefile

Put each local task in a file with an extension of .rake in the lib/tasks directory (e.g. lib/tasks/mything.rake):

task :mything do
  puts 'I did something!'
end

Gemfile

Put each local snippet in a file with an extension of .bundler in the lib/gemfile directory (.e.g lib/gemfile/myoverride.bundler)

gem 'pry-byebug'

Berksfile

Put each local snippet in a file with an extension of .berks in the lib/berksfile directory (.e.g lib/berksfile/myoverride.berks)

gem 'pry-byebug'

Guardfile

Put each local snippet in a file with an extension of .guard in the lib/guardfile directory (.e.g lib/guardfile/myoverride.berks)

  guard :rake, task: :coverage do
    watch(%r{^spec/foo/.+_spec\.rb$})
    watch(%r{^spec/spec_helper\.rb$})
    watch(%r{^attributes/.+\.rb$})
    watch(%r{^resources/.+\.rb$})
    watch(%r{^providers/.+\.rb$})
    watch(%r{^libraries/.+\.rb$})
    watch(%r{^recipes/.+\.rb$})
    watch(%r{^metadata\.rb$})
  end
