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.

Bind DDNS

Description

Install and configure ISC Bind https://www.isc.org/downloads/bind/ with
full Dynamic DNS support.

On client side, install nsupdate, provide a generic provider and a recipe
to update DNS entries.

Usage

Easy Setup

Add recipe[bind-ddns::server] in your run-list to install and configure
Bind. Configuration will be fetched from attributes options, zones and
keys.

To add a client, add recipe[bind-ddns::client]. nsupdate recipe will
update all records defined in records.

To see an example, look at [.kitchen.yml](.kitchen.yml).

Test

This cookbook is fully tested through the installation of a server and a client
in docker hosts. This uses kitchen, docker and some monkey-patching.

If you run kitchen list, you will see 2 suites, Each corresponds to a different
server:

  • server-ddns-centos-7: Bind server
  • client-ddns-centos-7: DNS client with nsupdate

For more information, see [.kitchen.yml](.kitchen.yml) and [test](test)
directory.

Changes

1.0.0:

  • Initial version with Centos 7 support

Requirements

Cookbooks

Declared in [metadata.rb](metadata.rb).

Gems

Declared in [Gemfile](Gemfile).

Platforms

  • RHEL Family 7, tested on Centos

Note: it should work fine on Debian 8 but the official docker image does not
allow systemd to work easily, so it could not be tested.

Attributes

Configuration is done by overriding default attributes. All configuration keys
have a default defined in [attributes/default.rb](attributes/default.rb).
Please read it to have a comprehensive view of what and how you can configure
this cookbook behavior.

Note: for fields needing an IP address, it is possible to set an interface
name, which will be resolved to its first non-local address.

Contributing

You are more than welcome to submit issues and merge requests to this project.

Commits

Your commits must pass git log --check and messages should be formated
like this (based on this excellent
post):

Summarize change in 50 characters or less

Provide more detail after the first line. Leave one blank line below the
summary and wrap all lines at 72 characters or less.

If the change fixes an issue, leave another blank line after the final
paragraph and indicate which issue is fixed in the specific format
below.

Fix #42

Also do your best to factor commits appropriately, ie not too large with
unrelated things in the same commit, and not too small with the same small
change applied N times in N different commits. If there was some accidental
reformatting or whitespace changes during the course of your commits, please
rebase them away before submitting the MR.

Files

All files must be 80 columns width formatted (actually 79), exception when it
is not possible.
