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.

node.default['postfix-dovecot']['common_name'] = ''
include_recipe 'postfix-dovecot'

See the ssl_certificate namespace documentation for more information.

Usage Example

Including in a Cookbook Recipe

Running it from a recipe:

node['postfix-dovecot']['postmaster_address'] = ''
node['postfix-dovecot']['hostname'] = ''

include_recipe 'postfix-dovecot::default'

postfixadmin_admin '' do
  password 'sup3r-s3cr3t-p4ss'
  action :create

postfixadmin_domain '' do
  login_username ''
  login_password 'sup3r-s3cr3t-p4ss'

postfixadmin_mailbox '' do
  password 'alice'
  login_username ''
  login_password 'sup3r-s3cr3t-p4ss'

postfixadmin_alias '' do
  goto ''
  login_username ''
  login_password 'sup3r-s3cr3t-p4ss'

Don't forget to include the postfix-dovecot cookbook as a dependency in the metadata.

# metadata.rb

depends 'postfix-dovecot'

Including in the Run List

Another alternative is to include the default recipe in your Run List.

  "run_list": [

PostgreSQL Support

PostgreSQL support should be considered experimental at the moment. Use at your own risk.

Any feedback you can provide regarding the PostgreSQL support will be greatly appreciated.

PostgreSQL Support on Debian and Ubuntu

Due to postgresql cookbook issue #108, you should configure your system locale correctly for PostgreSQL to work. You can use the locale cookbook to fix this. For example:

ENV['LANGUAGE'] = ENV['LANG'] = node['locale']['lang']
ENV['LC_ALL'] = node['locale']['lang']
include_recipe 'locale'
# ...
node.default['postfix-dovecot']['database']['type'] = 'postgresql'
include_recipe 'postfix-dovecot'

PostgreSQL Support on CentOS and Fedora

Tha lastest CentOS and Fedora versions come without PostgreSQL support in their Postfix package. So we need to recompile it using the SRPM, enabling the PostgreSQL support.

The postfix-dovecot::postfix_postgresql recipe takes care of it transparently. This recipe has been tested using test-kitchen, but it may not work for all cases. This code has been tested in the following platforms:

  • CentOS 6.5 and 7.0
  • Fedora 19 and 20.

Please, let us know if you use PostgreSQL support successfully on any other platform.

PostgreSQL Support on Amazon Linux

Support for PostgreSQL on Amazon Linux is still not finished because of the need to patch the provided SRPM. Its implementation would require a little monkey-patching.

Please, open an issue if you need the support of PostgreSQL on Amazon Linux.

PostgreSQL Versions < 9.3

If you are using PostgreSQL version < 9.3, you may need to adjust the shmmax and shmall kernel parameters to configure the shared memory. You can see [the example used for the integration tests](test/cookbooks/postfix-dovecot_test/recipes/postgresql_memory.rb).

Some cookbook attributes are used internally to add PostgreSQL support. They can make your journey smoother if you need to improve PostgreSQL support.

<td>A list of yum repositories to add to include the source SRPMs.</td>
<td>Packages required for compiling Postfix from sources.</td>
<td>An array with two values, a pattern and a replacement. This Regexp is used to get the final Postfix RPM name from the SRPM name.</td>
<td>A string with the arguments to pass to <em>rpmbuild</em> application. Normally contains the required option to enable PostgreSQL in the Postfix SRPM.</td>

See the attributes/postfix_postgresql.rb file for default examples.

Please do not hesitate to make a PR if you improve the PostgreSQL support ;-)




Please do not hesitate to open an issue with any questions or problems.
