Cookbooks and gems
- 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.
recipe[bind-ddns::server] in your run-list to install and configure
Bind. Configuration will be fetched from attributes
To add a client, add
recipe[bind-ddns::client]. nsupdate recipe will
update all records defined in
To see an example, look at .kitchen.yml.
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
Configuration is done by overriding default attributes. All configuration keys have a default defined in 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.
Specific configuration (client or server)
To allow clients and servers to share a same role, it is possible to define specific configuration keys applicable to one of the status (client or server).
Specific configurations can be any of the attributes defined in attributes/default.rb but in either "client-config" or "server-config" sub-tree.
A node is declared as server if its FQDN is included in attribute "['bind-ddns']['servers']" defined as an array. Else, it is considered as a client.
Call init and then, following the node status, call client or server recipe.
Determine if the current machine is a server or a client. Write the result in "run_state['bind-ddns']['status']". Then merge default and specific (client or server) configurations and store the result in "run_state['bind-ddns']['config']".
Note: init is included in all recipes.
Install Bind package.
Install Bind utils package.
Configure Bind server: named.conf, keys and zones. Then check configuration through named-checkconf.
Enable and start named service, subscribes on named-checkconf resource.
Call bind-ddns default provider (which call nsupdate command) based on
records. See .kitchen.yml for more information.
Replace some missing configuration attributes: - domain (name attribute) by the FQDN - data by the ip defined in "node[:ipaddress]" - zone by the tail part of the domain
Set resolv.conf using
Install Bind utils, configure resolv.conf if requested (by attribute
set_resolv_conf) with recipe resolvconf and call nsupdate recipe.
Install, configure and launch Bind. Then call client recipe.
Add, update or remove a DNS record using nsupdate. Read the resources/default.rb for more details.
bind_ddns 'test.foo' do
:delete to delete an entry (default is :add).
