In Ocata nova uses the transport_url for communication to rabbitmq.
In the charm the default port 5672 was assumed. However, when
rabbitmq uses SSL it changes the port to 5671.
This pulls in the fix which makes the default port explicit and
changes the port when SSL is in use.
Configure the scheduler to automatically discover and
map hosts into cell1 every 30 seconds ensuring that
hosts are discovered automatically.
This will be completed by future work to orchestrate
the enablement and mapping of compute hosts into cells
using relations and actions at a later date.
The cloud-compute-relation-changed hook returns early in some
cases, such as when migration-auth-type is not set. Move the
add_hosts_to_cell call earlier in the hook so that it always
has a chance to be called when a compute host is added. This
also fixes the broken indentation.
A minimal cells v2 setup is required in Ocata, which includes the
following databases:
1. An API database (named nova_api)
2. A special cell0 database (named cell0)
3. A "cell1" database (named nova - we're using the nova db as cell1)
The order of nova-manage commands is also updated in this commit.
The 'nova-manage api_db sync' must occur first because 'nova-manage
cell_v2' commands use the API database. 'nova-manage db sync' must
then be run after the 'nova-manage cell_v2' commands.
Finally, 'nova-manage cell_v2 discover_hosts' must be run whenever a
new compute node is introduced to add the host to cell1.
This commit includes a sync of charm-helpers to pick up AMQPContext
updates for transport_url.
nova-cloud-controller provides its region setting to the nova
services hosted in neutron-gateway units; ensure that any changes
to configuration are correctly propagated to related units.
