Managing Nodes
Node is a logical object managed by the Senlin service. A node can be a member of at most one cluster at any time. A node can be an orphan node which means it doesn't belong to any clusters.
List Nodes
To examine the list of Nodes:
../../examples/clustering/node.py
When listing nodes, you can specify the sorting option using the
sort parameter and you can do pagination using the
limit and marker parameters.
Full example: manage node
Create Node
When creating a node, you will provide a dictionary with keys and values according to the node type referenced.
../../examples/clustering/node.py
Optionally, you can specify a metadata keyword argument
that contains some key-value pairs to be associated with the node.
