This allows security groups to be created and attached to the neutron
port that the loadbalancer is using on the subnet.
The security group ID that is assigned to the nodes needs to be
provided, to allow for traffic from the loadbalancer to the nodePort
to be refelected in the rules.
This adds two config items to the LoadBalancer options -
ManageSecurityGroups (bool)
NodeSecurityGroupID (string)
We had another bug where we confused the hostname with the NodeName.
To avoid this happening again, and to make the code more
self-documenting, we use types.NodeName (a typedef alias for string)
whenever we are referring to the Node.Name.
A tedious but mechanical commit therefore, to change all uses of the
node name to use types.NodeName
Also clean up some of the (many) places where the NodeName is referred
to as a hostname (not true on AWS), or an instanceID (not true on GCE),
etc.
This removes the need to manually specify the version in all but unusual
cases.
For most installs this will effectively flip the default from
v1 (deprecated) to v2 so conservative existing installs may want to
manually configure "lb-version = v1" before upgrading.
In OpenStack Mitaka, the name field for members was added as an optional
field but does not exist in Liberty. Therefore the current
implementation for lbaas v2 will not work in Liberty.
