Synopsis

• This module removes, or creates DHCP option sets, and can associate them to a VPC. Optionally, a new DHCP Options set can be created that converges a VPC’s existing DHCP option set with values provided. When dhcp_options_id is provided, the module will 1. remove (with state=’absent’) 2. ensure tags are applied (if state=’present’ and tags are provided 3. attach it to a VPC (if state=’present’ and a vpc_id is provided. If any of the optional values are missing, they will either be treated as a no-op (i.e., inherit what already exists for the VPC) To remove existing options while inheriting, supply an empty value (e.g. set ntp_servers to [] if you want to remove them from the VPC’s options) Most of the options should be self-explanatory.

Requirements (on host that executes module)

• boto
• python >= 2.6

## Create a DHCP option set with 4.4.4.4 and 8.8.8.8 as the specified DNS servers, with tags
## but do not assign to a VPC
