Hey Guys,
Sorry for dropping the ball on this one. I'd like to avoid passing in
the entire Cluster object if I can help it. The next version will have a
'groups' attribute in the Node class. For now you can access the various
groups that a node is a member of by using the groups attribute in the
Node class's instance attribute:
In[1] groups = n.instance.groups
In[2] g = groups[0]
In[3] print g.id
Out[3] '_at_sc-mycluster'
Checking whether a group is a starcluster name is simply a matter of
testing whether the g.id starts with static.SECURITY_GROUP_PREFIX:
In[4] is_cluster_group = g.id.startswith(static.SECURITY_GROUP_PREFIX)
In the next version accessing the groups will simply be:
In[1] n.groups
This will contain *all* security groups. We will also have a
cluster_groups attribute in the next version for listing *only* cluster
security groups:
In[2] n.cluster_groups
Last, for the time being you can access the *boto* ec2 connection object
(not EasyEC2) which will allow you to make boto calls to EC2 via the
n.instance.connection attribute:
In[1] n.instance.connection.authorize_security_group(...)
Keep in mind this n.instance.connection object is a *boto* ec2
connection not StarCluster's EasyEC2 connection. In the next version you
will have an 'ec2' attribute in the Node class that will allow you to
make aws/ec2 calls via the EasyEC2 object.
Does this make sense?
