IP Address Management controller

Responsibilities:

• Used for KKP setups that do not have DHCP available
• Can only be used for vsphere, as all other platforms have DHCP
• The IPAM controller gets configured with a set of subnets
• For all machines with an machine-controller.kubermatic.io/initializers annotation that contains the value ipam, it will allocate an IP address

Documentation

Overview

Package ipam contains a controller responsible for assigning IP addresses from a configured pool to machines that have an annotation keyed `machine-controller.kubermatic.io/initializers` which contains the value ipam. After that is done, the `ipam` value is removed.

This is used for environments where no DHCP is available. The aforementioned annotation will keep the machine-controller from reconciling the machine.
