NodegroupOptions
NodeGroup properties interface.
- Parameters:
ami_type (
Optional
[NodegroupAmiType
]) – The AMI type for your node group. If you explicitly specify the launchTemplate with custom AMI, do not specify this property, or the node group deployment will fail. In other cases, you will need to specify correct amiType for the nodegroup. Default: - auto-determined from the instanceTypes property when launchTemplateSpec property is not specifiedcapacity_type (
Optional
[CapacityType
]) – The capacity type of the nodegroup. Default: - ON_DEMANDdesired_size (
Union
[int
,float
,None
]) – The current number of worker nodes that the managed node group should maintain. If not specified, the nodewgroup will initially createminSize
instances. Default: 2disk_size (
Union
[int
,float
,None
]) – The root device disk size (in GiB) for your node group instances. Default: 20force_update (
Optional
[bool
]) – Force the update if the existing node group’s pods are unable to be drained due to a pod disruption budget issue. If an update fails because pods could not be drained, you can force the update after it fails to terminate the old node whether or not any pods are running on the node. Default: trueinstance_type (
Optional
[InstanceType
]) – (deprecated) The instance type to use for your node group. Currently, you can specify a single instance type for a node group. The default value for this parameter ist3.medium
. If you choose a GPU instance type, be sure to specify theAL2_x86_64_GPU
with the amiType parameter. Default: t3.mediuminstance_types (
Optional
[Sequence
[InstanceType
]]) – The instance types to use for your node group. Default: t3.medium will be used according to the cloudformation document.labels (
Optional
[Mapping
[str
,str
]]) – The Kubernetes labels to be applied to the nodes in the node group when they are created. Default: - Nonelaunch_template_spec (
Union
[LaunchTemplateSpec
,Dict
[str
,Any
],None
]) – Launch template specification used for the nodegroup. Default: - no launch templatemax_size (
Union
[int
,float
,None
]) – The maximum number of worker nodes that the managed node group can scale out to. Managed node groups can support up to 100 nodes by default. Default: - desiredSizemin_size (
Union
[int
,float
,None
]) – The minimum number of worker nodes that the managed node group can scale in to. This number must be greater than or equal to zero. Default: 1nodegroup_name (
Optional
[str
]) – Name of the Nodegroup. Default: - resource IDnode_role (
Optional
[IRole
]) – The IAM role to associate with your node group. The Amazon EKS worker node kubelet daemon makes calls to AWS APIs on your behalf. Worker nodes receive permissions for these API calls through an IAM instance profile and associated policies. Before you can launch worker nodes and register them into a cluster, you must create an IAM role for those worker nodes to use when they are launched. Default: - None. Auto-generated if not specified.release_version (
Optional
[str
]) – The AMI version of the Amazon EKS-optimized AMI to use with your node group (for example,1.14.7-YYYYMMDD
). Default: - The latest available AMI version for the node group’s current Kubernetes version is used.remote_access (
Union
[NodegroupRemoteAccess
,Dict
[str
,Any
],None
]) – The remote access (SSH) configuration to use with your node group. Disabled by default, however, if you specify an Amazon EC2 SSH key but do not specify a source security group when you create a managed node group, then port 22 on the worker nodes is opened to the internet (0.0.0.0/0) Default: - disabledsubnets (
Union
[SubnetSelection
,Dict
[str
,Any
],None
]) – The subnets to use for the Auto Scaling group that is created for your node group. By specifying the SubnetSelection, the selected subnets will automatically apply required tags i.e.kubernetes.io/cluster/CLUSTER_NAME
with a value ofshared
, whereCLUSTER_NAME
is replaced with the name of your cluster. Default: - private subnetstags (
Optional
[Mapping
[str
,str
]]) – The metadata to apply to the node group to assist with categorization and organization. Each tag consists of a key and an optional value, both of which you define. Node group tags do not propagate to any other resources associated with the node group, such as the Amazon EC2 instances or subnets. Default: - Nonetaints (
Optional
[Sequence
[Union
[TaintSpec
,Dict
[str
,Any
]]]]) – The Kubernetes taints to be applied to the nodes in the node group when they are created. Default: - Nonecluster (
ICluster
) – Cluster resource.
