Makes an API call to rancher to create a new cluster using the given parameters. :param rancher_config: :param s: A Session object initialized by create_rancher_session. :type s: requests.Session :param cluster_name: The name for the cluster in Rancher. :type cluster_name: str :param iso_time_stamp: Iso time stamp which is written to the description of the new cluster. :type iso_time_stamp: str :param rke_config: Rancher kubernetes engine configuration as produced by rke template. :type rke_config: dict :return: The id of the new cluster in rancher. :rtype: str

Parameters
Return type

str

ironik.rancher.rancher_api_caller.create_rancher_node_pool(s, cluster_name, cluster_id, node_template_id, is_master, kubernetes_config, rancher_config)[source]

Makes an API call the rancher API to create a new node pool for the given cluster with the given node template. Quantity of 0 will be accepted but the new node pool will not show up in the UI. :param rancher_config: :param kubernetes_config: :param cluster_name: Name of the cluster, used to prefix the name of the nodes. :type cluster_name: str :param s: A Session object initialized by create_rancher_session. :type s: requests.Session :param cluster_id: Id of the cluster in rancher. :type cluster_id: str :param node_template_id: Id of the node template to use for the cluster. :type node_template_id: str :param is_master: Indicates whether the nodes are supposed to be master nodes for the kubernetes cluster or just worker nodes.
