-- 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 (Chef): @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.
