This resource will help you to manage a ManagedKubernetes Cluster in Alibaba Cloud Kubernetes Service.

-> NOTE: Available since v1.26.0.

-> NOTE: It is recommended to create a cluster with zero worker nodes, and then use a node pool to manage the cluster nodes.

-> NOTE: Kubernetes cluster only supports VPC network and it can access internet while creating kubernetes cluster. A Nat Gateway and configuring a SNAT for it can ensure one VPC network access internet. If there is no nat gateway in the VPC, you can set new_nat_gateway to "true" to create one automatically.

-> NOTE: Creating kubernetes cluster need to install several packages and it will cost about 15 minutes. Please be patient.

-> NOTE: From version 1.9.4, the provider supports to download kube config, client certificate, client key and cluster ca certificate after creating cluster successfully, and you can put them into the specified location, like '~/.kube/config'.

-> NOTE: From version 1.20.0, the provider supports disabling internet load balancer for API Server by setting false to slb_internet_enabled.

-> NOTE: If you want to manage Kubernetes, you can use Kubernetes Provider.

-> NOTE: You need to activate several other products and confirm Authorization Policy used by Container Service before using this resource. Please refer to the Authorization management and Cluster management sections in the Document Center.

-> NOTE: From version 1.72.0, Some parameters have been removed from resource,You can check them below and re-import the cluster if necessary.

-> NOTE: From version 1.120.0, Support for cluster migration from Standard cluster to professional.

-> NOTE: From version 1.177.0+, runtime,enable_ssh,rds_instances,exclude_autoscaler_nodes,worker_number,worker_instance_types,password,key_name,kms_encrypted_password,kms_encryption_context,worker_instance_charge_type,worker_period,worker_period_unit,worker_auto_renew,worker_auto_renew_period,worker_disk_category,worker_disk_size,worker_data_disks,node_name_mode,node_port_range,os_type,platform,image_id,cpu_policy,user_data,taints,worker_disk_performance_level,worker_disk_snapshot_policy_id,install_cloud_monitor are deprecated. We Suggest you using resource alicloud_cs_kubernetes_node_pool to manage your cluster worker nodes.

-> NOTE: From version 1.212.0, runtime,enable_ssh,rds_instances,exclude_autoscaler_nodes,worker_number,worker_instance_types,password,key_name,kms_encrypted_password,kms_encryption_context,worker_instance_charge_type,worker_period,worker_period_unit,worker_auto_renew,worker_auto_renew_period,worker_disk_category,worker_disk_size,worker_data_disks,node_name_mode,node_port_range,os_type,platform,image_id,cpu_policy,user_data,taints,worker_disk_performance_level,worker_disk_snapshot_policy_id,install_cloud_monitor,kube_config,availability_zone are removed.
