Instance Method Details

#add_graffiti(obj_type, obj_hash, graffiti, login, password_callback = PasswordCallback) ⇒ Object

Add a new graffiti to given objects. We’re assuming that graffiti is a string of “key:value” format obj_type is a string that describe the type of the obj (e.g NodeGroup) obj_hash is the hash returned from calling get_objects

      },
      , password_callback);
  end
end

#add_node_group_node_assignment(node_id, node_group_id, login, password_callback = PasswordCallback) ⇒ Object

Add the given node into the given nodegroup by directly creating the node_group_node_assignment First argument is the id of the node Second argument is the id of the nodegroup

  set_objects('node_group_node_assignments', nil, setdata, , password_callback)
end

#add_node_group_node_assignments(nodes, nodegroups, login, password_callback = PasswordCallback) ⇒ Object

The first argument is a hash returned by a ‘nodes’ call to get_objects The second argument is a hash returned by a ‘node_groups’ call to get_objects This method does the same thing as the add_nodes_to_nodegroups method. However, it will not be susceptible to the race condition mentioned in add_nodes_to_nodegroups method This is because it directly talks to the node_group_node_assignments controller

    end
  end
end

#add_nodegroups_to_nodegroups(child_groups, parent_groups, login, password_callback = PasswordCallback) ⇒ Object

Both arguments are hashes returned by a ‘node_groups’ call to get_objects NOTE: For the parent groups you must have requested that the server include ‘child_groups’ in the result
