This refactors the nova-novncproxy configuration in TripleO
so that it can be used in a cloud where the compute hosts
don't each have to be assigned a public IP. With the
new configuration the nova-novncproxy is configured
to run on the nova-api (controller) node which
typically will have a public IP assigned to it.
Specific changes include:
-move novnc element to nova-novncproxy
-move all the nova-novncproxy stuff out of nova-kvm into
the new nova-novncproxy element
-configures Fedora iptables rules to support noVNC
connections on 6080
-Adds a new nova.public_ip parameter which is used
to construct the novncproxy_base_url. This may be
returned directly to cloud users via
'nova get-vnc-console' or consumed by Horizon.
-Set vncserver_proxyclient_address to the real
local(internal) IP address for the compute host.
Previously we used 127.0.0.1 which won't work
unless nova-novncproxy runs on the Nova compute host.
To do this we use {{local-ipv4}} which should always
be the Heat provided local management IP address
for the compute host.

Image building rules for OpenStack images
These elements are used to build disk images for deploying OpenStack via Heat. They are built as part of the TripleO (https://wiki.openstack.org/wiki/TripleO) umbrella project.
Instructions
Checkout this source tree and also the diskimage builder, export an ELEMENTS_PATH to add elements from this tree, and build any disk images you need.
git clone https://git.openstack.org/openstack/diskimage-builder.git
git clone https://git.openstack.org/openstack/tripleo-image-elements.git
export ELEMENTS_PATH=tripleo-image-elements/elements
diskimage-builder/bin/disk-image-create -u base vm bootstrap local-config stackuser heat-cfntools -a i386 -o bootstrap
Common element combinations
Always include heat-cfntools in images that you intend to boot via heat : if that is not done, then the user ssh keys are not reliably pulled down from the metadata server due to interactions with cloud-init.
Architecture
OpenStack images are intended to be deployed and maintained using Nova + Heat.
As such they should strive to be stateless, maintained entirely via automation.
Configuration
In a running OpenStack there are several categories of config.
- per user - e.g. ssh key registration with nova: we repeat this sort of config every time we add a user.
- local node - e.g. nova.conf or ovs-vsctl add-br br-ex : settings that apply individually to machines
- inter-node - e.g. credentials on rabbitmq for a given nova compute node
- application state - e.g. 'neutron net-create ...' : settings that apply to the whole cluster not on a per-user / per-tenant basis
We have five places we can do configuration in TripleO:
- image build time
- in-instance heat-driven (ORC scripts)
- in-instance first-boot scripts [deprecated]
- from outside via APIs
- orchestrated by Heat
Our current heuristic for deciding where to do any particular configuration step:
- per user config should be done from the outside via APIs, even for users like 'admin' that we know we'll have. Note that service accounts are different - they are a form of inter-node configuration.
- local node configuration should be done via ORC driven by Heat and/or configuration management system metadata.
- inter-node configuration should be done by working through Heat. For instance, creating a rabbit account for a nova compute node is something that Heat should arrange, though the act of creating is probably done by a script on the rabbit server - triggered by Heat - and applying the config is done on the compute node by the local node script - again triggered by Heat.
- application state changes should be done from outside via APIs
- first-boot scripts should not be used.
