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. Come be part of shaping the direction of Supermarket by opening issues and pull requests or by joining us on the Chef Mailing List.

Description

Installs and configures CouchDB. Optionally can install CouchDB from sources.

Requirements

Requires a platform that can install Erlang from distribution packages.

Platform

Originally tested on Debian 5+, Ubuntu 8.10+, OpenBSD and FreeBSD.

Also works on Red Hat, CentOS and Fedora, requires the EPEL yum repository.

Tested via Test Kitchen (1.0-alpha):

  • Ubuntu 10.04, 12.04
  • CentOS 5.8, 6.3

Cookbooks

  • erlang

When using the couchdb::source recipe, the build-essential recipe
is required. It is not a direct dependency of this cookbook as it is
an optional installation method, and package installation is
recommended.

Attributes

Cookbook attributes are named under the couch_db keyspace.

  • node['couch_db']['src_checksum'] - sha256sum of the default version of couchdb to download
  • node['couch_db']['src_version'] - default version of couchdb to download, used in the full URL to download.
  • node['couch_db']['src_mirror'] - full URL to download.
  • node['couch_db']['install_erlang'] - specify if erlang should be installed prior to couchdb, true by default.

Configuration

The local.ini file is dynamically generated from attributes. Each key in
node['couch_db']['config'] is a CouchDB configuration directive, and will
be rendered in the config file. For example, the attribute:

node['couch_db']['config']['httpd']['bind_address'] = "0.0.0.0"

Will result in the following lines in the local.ini file:

[httpd]
bind_address = "0.0.0.0"

The attributes file contains default values for platform-independent
parameters. All parameter values that expect a path argument are
not set by default. The default values that are currently set have
been taken from the CouchDB configuration
wiki page.

The resulting configuration file is now dynamically rendered from the
attributes. Each subkey below the config key is a specific section
of the local.ini file. Then each subkey in a section is a parameter
associated with a value.

You should consult the CouchDB documentation for specific
configuration details.

For values that are "on" or "off", they should be specified as literal
true or false. Any configuration option set to the literal nil will
be skipped entirely. All other values (e.g., string, numeric literals) will
be used as is. So for example:

node.default['couch_db']['config']['couchdb']['os_process_timeout'] = 5000
node.default['couch_db']['config']['couchdb']['delayed_commits'] = true
node.default['couch_db']['config']['couchdb']['batch_save_interval'] = nil
node.default['couch_db']['config']['httpd']['port'] = 5984
node.default['couch_db']['config']['httpd']['bind_address'] = "127.0.0.1"

Will result in the following config lines:

[couchdb]
os_process_timeout = 5000
delayed_commits = true

[httpd]
port = 5984
bind_address = 127.0.0.1

(no line printed for batch_save_interval as it is nil)

Recipes

default

Installs the couchdb package, creates the data directory and starts the couchdb service.
