Install and configure ISC Kea, a Modern Open Source DHCPv4 & DHCPv6 Server.
Can also: - configure network interfaces by the use of cookbook network_interfaces_v2, for instance to set a static address at the server and dhcp for the clients.
- configure an exporter script to expose DHCP client metrics following Prometheus format. Only IP lifetime validity of dynamically assigned network interface currently reported.
Declared in [metadata.rb](metadata.rb) and in [Gemfile](Gemfile).
- RHEL Family 7, tested on Centos
It should be easy to add a new platform.

Kea. Configuration will be fetched from attributes
node['kea-dhcp']['kea-conf']. It directly follows '/etc/kea/kea.conf' format.

To see examples, look at [.kitchen.yml](.kitchen.yml).
This cookbook is fully tested through the installation of a server and a node 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-centos-7: Kea server listening on eth1
- node-centos-7: generic node with eth1 configured in dhcp
For more information, see [.kitchen.yml](.kitchen.yml) and [test](test) directory.
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.
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](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
node['kea-dhcp']['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 by looking if current
fqdn is included in
node['kea-dhcp']['servers'] (empty by default). Write the
run_state['kea-dhcp']['status']. Then merge default and specific
(client or server) configurations and store the result in
