The main highlight of this cookbook is the database
and database_user
resources for managing databases and database users in a RDBMS. Providers for MySQL, PostgreSQL and SQL Server are also provided, see usage documentation below.
This cookbook has been deprecated. The original intent was to abstract database implementation details away from the end user. In hindsight this was a mistake as it is difficult / impossible to make a generic interface for databases that works accross all systems. Instead we plan to move the individual providers into their respective cookbooks (mysql, postgresql, sqlite, sql_server) where they can fully utilize the feature set of the underlying DB systems.
- Debian / Ubuntu derivatives
- RHEL derivatives
- Fedora
- Chef 12.1+
- postgresql
These resources aim to expose an abstraction layer for interacting with different RDBMS in a general way. Currently the cookbook ships with providers for MySQL, PostgreSQL and SQL Server. Please see specific usage in the Example sections below. The providers use specific Ruby gems installed under Chef's Ruby environment to execute commands and carry out actions. These gems will need to be installed before the providers can operate correctly. Specific notes for each RDBS flavor:
-
MySQL: leverages the
mysql2
gem, which can be installed with themysql2_chef_gem
resource prior to use (available on the Supermarket). You must depend on themysql2_chef_gem
cookbook, then use amysql2_chef_gem
resource to install it. The resource allows the user to select MySQL client library versions, as well as optionally select MariaDB libraries. -
PostgreSQL: leverages the
pg
gem which is installed as part of thepostgresql::ruby
recipe. You must declareinclude_recipe "database::postgresql"
to include this. -
SQL Server: leverages the
tiny_tds
gem which is installed as part of thesql_server::client
recipe. -
SQLite: leverages the
sqlite3
gem which is installed as part of thedatabase::sqlite
recipe. You must declareinclude_recipe "database::sqlite"
to include this.
Manage databases in a RDBMS. Use the proper shortcut resource depending on your RDBMS: mysql_database
, postgresql_database
, sql_server_database
or sqlite_database
.
:create
: create a named database:drop
: drop a named database:query
: execute an arbitrary query against a named database
-
database_name: name attribute. Name of the database to interact with
-
connection: hash of connection info. valid keys include
:host
,:port
,:username
, and:password
-
only for MySQL DB*:
:flags
(seeMysql2::Client@@default_query_options[:connect_flags]
):default_file
,:default_group
(see https://github.com/brianmario/mysql2#reading-a-mysql-config-file)
-
only for PostgreSQL:
:database
(overwrites parameterdatabase_name
) -
not used for SQLlite
-
-
sql: string of sql or a block that executes to a string of sql, which will be executed against the database. used by
:query
action only -
The database cookbook uses the
mysql2
gem.
"The value of host may be either a host name or an IP address. If host is NULL or the string "127.0.0.1", a connection to the local host is assumed. For Windows, the client connects using a shared-memory connection, if the server has shared-memory connections enabled. Otherwise, TCP/IP is used. For a host value of "." on Windows, the client connects using a named pipe, if the server has named-pipe connections enabled. If named-pipe connections are not enabled, an error occurs."
If you specify a :socket
key and are using the mysql_service resource to set up the MySQL service, you'll need to specify the path in the form /var/run/mysql-<instance name>/mysqld.sock
.
