-- Associates a new node with the server. For more information about how to
-- disassociate a node, see DisassociateNode.
--
-- On a Chef server: This command is an alternative to @knife bootstrap@.
--
-- Example (Chef):
-- @aws opsworks-cm associate-node --server-name @/@MyServer@/@ --node-name @/@MyManagedNode@/@ --engine-attributes \"Name=@/@CHEF_ORGANIZATION@/@,Value=default\" \"Name=@/@CHEF_NODE_PUBLIC_KEY@/@,Value=@/@public-key-pem@/@\"@
--
-- On a Puppet server, this command is an alternative to the
-- @puppet cert sign@ command that signs a Puppet node CSR.
--
-- Example (Puppet):
-- @aws opsworks-cm associate-node --server-name @/@MyServer@/@ --node-name @/@MyManagedNode@/@ --engine-attributes \"Name=@/@PUPPET_NODE_CSR@/@,Value=@/@csr-pem@/@\"@
--
-- A node can can only be associated with servers that are in a @HEALTHY@
-- state. Otherwise, an @InvalidStateException@ is thrown. A
-- @ResourceNotFoundException@ is thrown when the server does not exist. A
-- @ValidationException@ is raised when parameters of the request are not
-- valid. The AssociateNode API call can be integrated into Auto Scaling
-- configurations, AWS Cloudformation templates, or the user data of a
-- server\'s instance.
