Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place.

app_database cookbook

Cookbook for Opscode Chef.

http://community.opscode.com/cookbooks/app_database

Description

Provides new resources/providers for managing application databases.

Features include migrations, automatic backups, and easier command-line access.

Currently supported databases include: MySQL (more coming, and contributions welcome)

This cookbook is part of a larger application management cookbook suite we'll be releasing in the near future. It is meant to be simple/concise, and then consumed by larger more complex cookbooks.

Migrations are primarily intended for initial provisioning, but can be used for updates if you increment the :schema_version attribute. There is no automatic rollback from schema update failures however.

For those database types that require authentication it is expected that the username/password and target database already exist. It is not recommended to use these resources under a database super-admin account.

Usage / Result

Given this sample resource declaration:

app_database "my_app" do
  action [ :configure, :backup, :migrate ]
  basepath "/tmp/app_database_test/mysql_test"  # required
  owner "nobody"                                # required
  uri "mysql://localhost/test"                  # required
  username "test_user"                          # optional
  password "test_pass"                          # optional
  schema_version "1.0"                          # optional
end

And a template file: templates/default/migrate/mysql.erb

-- THIS FILE IS ONLY REQUIRED FOR THE `:migrate` ACTION

<% if "#{@current_version}".empty? -%>
  --
  -- First migration only.
  --
  CREATE TABLE app_database_test(counter int);
  INSERT INTO app_database_test (counter) VALUES (0);
<% end -%>

<% v1 = Gem::Version.new(1.0)
   if @current_version < v1 && @new_version >= v1 -%>
  --
  -- Upgrade/Migrate up to version 1.0
  --
  UPDATE app_database_test SET counter=counter+1;
<% end -%>

Then the following files would be created during the Chef run:

%{basepath}/mysql.conf

[client]
host=localhost
port=3306
user=test_user
pass=test_pass
database=test

%{basepath}/backup-my_app-20130101.mysql.tgz

File would be a compressed tarball of the mysqldump for the database on the given date. Backup will only be attempted if the :backup action is used, and if there is not an existing backup for the day.

In this case the compressed sql file would be similar to:

--
-- Table structure for table `app_database_test`
--

DROP TABLE IF EXISTS `app_database_test`;
CREATE TABLE `app_database_test` (
  `counter` int(11) DEFAULT NULL
) ENGINE=MyISAM DEFAULT CHARSET=utf8;

--
-- Dumping data for table `app_database_test`
--

LOCK TABLES `app_database_test` WRITE;
INSERT INTO `app_database_test` VALUES (1);
UNLOCK TABLES;
