Response

Parameters

Name	In	Type	Description
`clustertemplates`	body	array	The list of all cluster templates in Magnum.
`insecure_registry`	body	string	The URL pointing to users’s own private insecure docker registry to deploy and run docker containers.
`links`	body	array	Links to the resources in question.
`updated_at`	body	string	The date and time when the resource was updated. If the resource has not been updated, this field will be `null`. The date and time stamp format is ISO 8601: CCYY-MM-DDThh:mm:ss±hh:mm For example, `2015-08-27T09:49:58-05:00`. The `±hh:mm` value, if included, is the time zone as an offset from UTC. In this example, the offset value is `-05:00`.
`floating_ip_enabled`	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.
`fixed_subnet` (Optional)	body	string	Fixed subnet that are using to allocate network address for nodes in bay/cluster.
`master_flavor_id` (Optional)	body	string	The flavor of the master node for this baymodel/cluster template.
`uuid`	body	UUID	The UUID of the cluster template.
`no_proxy` (Optional)	body	string	When a proxy server is used, some sites should not go through the proxy and should be accessed normally. In this case, users can specify these sites as a comma separated list of IPs. The default is `None`.
`https_proxy` (Optional)	body	string	The IP address for a proxy to use when direct HTTPS access from the servers to sites on the external internet is blocked. This may happen in certain countries or enterprises, and the proxy allows the servers and containers to access these sites. The format is a URL including a port number. The default is `None`.
`tls_disabled`	body	boolean	Transport Layer Security (TLS) is normally enabled to secure the bay/cluster. In some cases, users may want to disable TLS in the bay/cluster, for instance during development or to troubleshoot certain problems. Specifying this parameter will disable TLS so that users can access the COE endpoints without a certificate. The default is TLS enabled.
`keypair_id`	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`.
`public`	body	boolean	Access to a baymodel/cluster template is normally limited to the admin, owner or users within the same tenant as the owners. Setting this flag makes the baymodel/cluster template public and accessible by other users. The default is not public.
`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.
`docker_volume_size`	body	integer	The size in GB for the local storage on each server for the Docker daemon to cache the images and host the containers. Cinder volumes provide the storage. The default is 25 GB. For the `devicemapper` storage driver, the minimum value is 3 GB. For the `overlay` storage driver, the minimum value is 1 GB.
`server_type`	body	string	The servers in the bay/cluster can be `vm` or `baremetal`. This parameter selects the type of server to create for the bay/cluster. The default is `vm`.
`external_network_id`	body	string	The name or network ID of a Neutron network to provide connectivity to the external internet for the bay/cluster. This network must be an external network, i.e. its attribute `router:external` must be `True`. The servers in the bay/cluster will be connected to a private network and Magnum will create a router between this private network and the external network. This will allow the servers to download images, access discovery service, etc, and the containers to install packages, etc. In the opposite direction, floating IPs will be allocated from the external network to provide access from the external internet to servers and the container services hosted in the bay/cluster.
`cluster_distro`	body	string	Display the attribute `os_distro` defined as appropriate metadata in image for the bay/cluster driver.
`image_id`	body	string	The name or UUID of the base image in Glance to boot the servers for the bay/cluster. The image must have the attribute `os_distro` defined as appropriate for the bay/cluster driver.
`volume_driver`	body	string	The name of a volume driver for managing the persistent storage for the containers. The functionality supported are specific to the driver.
`registry_enabled` (Optional)	body	boolean	Docker images by default are pulled from the public Docker registry, but in some cases, users may want to use a private registry. This option provides an alternative registry based on the Registry V2: Magnum will create a local registry in the bay/cluster backed by swift to host the images. The default is to use the public registry.
`docker_storage_driver`	body	string	The name of a driver to manage the storage for the images and the container’s writable layer. The default is `devicemapper`.
`apiserver_port`	body	integer	The exposed port of COE API server.
`name`	body	string	Name of the resource.
`created_at`	body	string	The date and time when the resource was created. The date and time stamp format is ISO 8601: CCYY-MM-DDThh:mm:ss±hh:mm For example, `2015-08-27T09:49:58-05:00`. The `±hh:mm` value, if included, is the time zone as an offset from UTC. In this example, the offset value is `-05:00`.
`network_driver`	body	string	The name of a network driver for providing the networks for the containers. Note that this is different and separate from the Neutron network for the bay/cluster. The operation and networking model are specific to the particular driver.
`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.
`coe`	body	string	Specify the Container Orchestration Engine to use. Supported COEs include `kubernetes`, `swarm`, `mesos`. If your environment has additional bay/cluster drivers installed, refer to the bay/cluster driver documentation for the new COE names.
`flavor_id`	body	string	The nova flavor ID or name for booting the node servers. The default is `m1.small`.
`master_lb_enabled`	body	boolean	Since multiple masters may exist in a bay/cluster, a Neutron load balancer is created to provide the API endpoint for the bay/cluster and to direct requests to the masters. In some cases, such as when the LBaaS service is not available, this option can be set to `false` to create a bay/cluster without the load balancer. In this case, one of the masters will serve as the API endpoint. The default is `true`, i.e. to create the load balancer for the bay.
`dns_nameserver`	body	string	The DNS nameserver for the servers and containers in the bay/cluster to use. This is configured in the private Neutron network for the bay/cluster. The default is `8.8.8.8`.
`hidden` (Optional)	body	boolean	Indicates whether the ClusterTemplate is hidden or not, the default value is false.
