Argument Reference
cluster_id- (Required) Unique identifier of the associated Managed Kubernetes cluster. Changing this creates a new node group. You can create up to eight group nodes in a cluster. Retrieved from the selectel_mks_cluster_v1 resource.project_id- (Required) Unique identifier of the associated Cloud Platform project. Changing this creates a new node group. Retrieved from the selectel_vpc_project_v2 resource. Learn more about Cloud Platform projects.region- (Required) Pool where the cluster is located, for example,ru-3. Changing this creates a new node group. Learn more about available pools in the Availability matrix.availability_zone(Required) Pool segment where all nodes of the node group are located. Changing this creates a new node group. Learn more about available pool segments in the Availability matrix.nodes_count(Required) Number of worker nodes in the node group. The maximum number of nodes in a node group is 15. Changing this resizes the node group ifenable_autoscaleis false.cpus(Optional) Number of CPU cores for each node. Can be skipped only whenflavor_idis set. Changing this creates a new node group. Learn more about Configurations.ram_mb(Optional) Amount of RAM in MB for each node. Can be skipped only whenflavor_idis set. Changing this creates a new node group. Learn more about Configurations.volume_gb(Optional) Volume size in GB for each node. Can be skipped only when flavor_id is set and local_volume istrue. Changing this creates a new node group. Learn more about Configurations.volume_type(Optional) Type of an OpenStack blockstorage volume for each node. Can be skipped only whenflavor_idis set andlocal_volumeistrue. Changing this creates a new node group. Available volume types arefast,basic, anduniversal. The format is<volume_type>.<availability_zone>. Learn more about Network volumes.local_volume(Optional) Specifies if nodes use a local volume. Changing this creates a new node group. Boolean flag, the default value is false.flavor_id(Optional) Unique identifier of an OpenStack flavor for all nodes in the node group. Changing this creates a new node group. Learn more about Flavors.labels(Optional) List of Kubernetes labels applied to each node in the node group.taints(Optional) List of Kubernetes taints applied to each node in the node group. Contains a key-value pair and an effect applied for the taint. Available effects areNoSchedule,PreferNoSchedule, andNoExecute. Learn more about Taints.keypair_name(Optional) Name of the SSH key added to all nodes. Changing this creates a new node group.affinity_policy(Optional) Specifies affinity policy of the nodes. Changing this creates a new node group. Available values aresoft-anti-affinityandsoft-affinity. The default value issoft-anti-affinity. For more information about affinity and anti-affinity, see the official Kubernetes documentation.enable_autoscale(Optional) Enables or disables autoscaling of the node group. Boolean flag, the default value is false.autoscale_min_nodesandautoscale_max_nodesmust be specified. Learn more about Autoscaling.autoscale_min_nodes(Optional) Minimum number of worker nodes in the node group.autoscale_max_nodes(Optional) Maximum number of worker nodes in the node group.
Attributes Reference
nodes- List of nodes in the node group.nodegroup_type- Type of the node group. Available values areSTANDARDandGPU.
Import
You can import a node group:
export OS_DOMAIN_NAME=<account_id>
export OS_USERNAME=<username>
export OS_PASSWORD=<password>
export SEL_PROJECT_ID=<selectel_project_id>
export SEL_REGION=<selectel_pool>
terraform import selectel_mks_nodegroup_v1.nodegroup_1 <cluster_id>/<nodegroup_id>
where:
<account_id>— Selectel account ID. The account ID is in the top right corner of the Control panel. Learn more about Registration.<username>— Name of the service user. To get the name, in the top right corner of the Control panel, go to the account menu ⟶ Profile and Settings ⟶ User management ⟶ the Service users tab ⟶ copy the name of the required user. Learn more about Service users.<password>— Password of the service user.<selectel_project_id>— Unique identifier of the associated Cloud Platform project. To get the project ID, in the Control panel, go to Cloud Platform ⟶ project name ⟶ copy the ID of the required project. Learn more about Cloud Platform projects.<selectel_pool>— Pool where the cluster is located, for example,ru-3. To get information about the pool, in the Control panel, go to Cloud Platform ⟶ Kubernetes. The pool is in the Pool column.<cluster_id>— Unique identifier of the cluster, for example,b311ce58-2658-46b5-b733-7a0f418703f2. To get the cluster ID, in the Control panel, go to Cloud Platform ⟶ Kubernetes ⟶ the cluster page ⟶ copy the ID at the top of the page under the cluster name, near the region and pool.<nodegroup_id>— Unique identifier of the node, for example,63ed5342-b22c-4c7a-9d41-c1fe4a142c13. To get the cluster ID, in the Control panel, go to Cloud Platform ⟶ Kubernetes. Click the required cluster ⟶ the required node group. The node group ID is at the top of the page under the node group name, near the region and pool.
