Re: Acquire the private IP via Starcluster as API

Hi Håvard,

My apologies for the lack of documentation for the API - it's a major
item on the todo list. For now here's a rough overview to print all of
the private ip addresses for all nodes in a cluster:

============================================================
from starcluster import config
from starcluster import cluster

# Load the config
cfg = config.StarClusterConfig().load()
# Create a cluster "manager" object
cm = cluster.ClusterManager(cfg)
# Fetch an active cluster
cl = cm.get_cluster('mycluster')
# Iterate through the nodes and print the private ip address
for node in cl.nodes:
    print "%s: %s" % (node.alias, node.private_ip_address)
============================================================

You can also fetch a specific node by name:

node = cl.get_node_by_alias('node003')

or by instance id:

node = cl.get_node_by_id('i-99999')

or by the instance's dns name:

node = cl.get_node_by_id('ec2-blahblah.amazonaws.com')

Hope that helps,

~Justin
