Module: ConfigBuilder::Model::Provider::Openstack::OpenStackConfigPatch

Defined in:
lib/config_builder/model/provider/openstack.rb

Overview

FIXME: PR this change to vagrant-openstack-provider. If a PR is not accepted, then update the role filter to merge all provider hashes into a single configuration block per-vm so that we don't have to worry about how providers feel or don't feel about the subject of merging.

#merge(other) ⇒ Object

A patch for the merge behavior of OpenStack::Config instances that allows us to merge volume boot settings together. Unpatched OpenStack just discards its current config and accepts whatever the new config is. In our case this would be a fragment of a complete volume_boot setting.
