Request

Parameters

Name	In	Type	Description
`name`	body	string	Name of the resource.
`discovery_url`	body	string	The custom discovery URL for node discovery. This is used by the COE to discover the servers that have been created to host the containers. The actual discovery mechanism varies with the COE. In some cases, Magnum fills in the server info in the discovery service. In other cases, if the `discovery_url` is not specified, Magnum will use the public discovery service at: https://discovery.etcd.io In this case, Magnum will generate a unique URL here for each bay and store the info for the servers.
`master_count`	body	integer	The number of servers that will serve as master for the bay/cluster. The default is 1. Set to more than 1 master to enable High Availability. If the option `master-lb-enabled` is specified in the baymodel/cluster template, the master servers will be placed in a load balancer pool.
`cluster_template_id`	body	UUID	The UUID of the cluster template.
`node_count`	body	integer	The number of servers that will serve as node in the bay/cluster. The default is 1.
`keypair`	body	string	The name of the SSH keypair to configure in the bay/cluster servers for ssh access. Users will need the key to be able to ssh to the servers in the bay/cluster. The login name is specific to the bay/cluster driver, for example with fedora-atomic image, default login name is `fedora`.
`create_timeout`	body	integer	The timeout for cluster creation in minutes. The value expected is a positive integer and the default is 60 minutes. If the timeout is reached during cluster creation process, the operation will be aborted and the cluster status will be set to `CREATE_FAILED`.
`master_flavor_id` (Optional)	body	string	The flavor of the master node for this baymodel/cluster template.
`labels` (Optional)	body	array	Arbitrary labels in the form of `key=value` pairs. The accepted keys and valid values are defined in the bay/cluster drivers. They are used as a way to pass additional parameters that are specific to a bay/cluster driver.
`flavor_id`	body	string	The nova flavor ID or name for booting the node servers. The default is `m1.small`.
`fixed_subnet` (Optional)	body	string	Fixed subnet that are using to allocate network address for nodes in bay/cluster.
`fixed_network` (Optional)	body	string	The name or network ID of a Neutron network to provide connectivity to the internal network for the bay/cluster.
`floating_ip_enabled` (Optional)	body	boolean	Whether enable or not using the floating IP of cloud provider. Some cloud providers used floating IP, some used public IP, thus Magnum provide this option for specifying the choice of using floating IP. If it’s not set, the value of floating_ip_enabled in template will be used.
