Module: `eks-node-group`

Terraform module to provision an EKS Managed Node Group for Elastic Kubernetes Service.

Instantiate it multiple times to create EKS Managed Node Groups with specific settings such as GPUs, EC2 instance types, or autoscale parameters.

IMPORTANT: When SSH access is enabled without specifying a source security group, this module provisions EKS Node Group nodes that are globally accessible by SSH (22) port. Normally, AWS recommends that no security group allows unrestricted ingress access to port 22 .

Introduction

This module creates an EKS Managed Node Group for an EKS cluster. It assumes you have already created an EKS cluster, but you can create the cluster and the node group in the same Terraform configuration. See our full-featured root module (a.k.a. component) eks/cluster for an example of how to do that.

Launch Templates

This module always uses a launch template to create the node group. You can create your own launch template and pass in its ID, or else this module will create one for you.

The AWS default for EKS is that if the launch template is updated, the existing nodes will not be affected. Only new instances added to the node group would get the changes specified in the new launch template. In contrast, when the launch template changes, this module can immediately create a new node group from the new launch template to replace the old one.

See the inputs create_before_destroy and immediately_apply_lt_changes for details about how to control this behavior.

Operating system differences

Currently, EKS supports 4 Operating Systems: Amazon Linux 2, Amazon Linux 2023, Bottlerocket, and Windows Server. This module supports all 4 OSes, but support for detailed configuration of the nodes varies by OS. The 4 inputs:

before_cluster_joining_userdata
kubelet_additional_options
bootstrap_additional_options
after_cluster_joining_userdata

are fully supported for Amazon Linux 2 and Windows, and take advantage of the bootstrap.sh supplied on those AMIs. NONE of these inputs are supported on Bottlerocket. On AL2023, only the first 2 are supported.

Note that for all OSes, you can supply the complete userdata contents, which will be untouched by this module, via userdata_override_base64.

Usage

Major Changes (breaking and otherwise)

With the v3.0.0 release of this module, support for Amazon Linux 2023 (AL2023) has been added, and some breaking changes have been made. Please see the release notes for details.

With the v2.0.0 (a.k.a. v0.25.0) release of this module, it has undergone major breaking changes and added new features. Please see the migration document for details.

For a complete example, see examples/complete.

For automated tests of the complete example using bats and Terratest (which tests and deploys the example on AWS), see test.

Sources of Information

The code examples below are manually updated and have a tendency to fall out of sync with actual code, particularly with respect to usage of other modules. Do not rely on them.
The documentation on this page about this module's inputs, outputs, and compliance is all automatically generated and is up-to-date as of the release date. After the code itself, this is your best source of information.
The code in examples/complete is automatically tested before every release, so that is a good place to look for verified example code. Keep in mind, however, it is code for testing, so it may not represent average use cases or best practices.
Of course, the READMEs and examples/complete directories in the other modules' GitHub repos are more authoritative with respect to how to use those modules than this README is.

that actually launches instances. Consult AWS documentation for details.

Default value: [ ]

create_before_destroy (bool) optional

If true (default), a new node group will be created before destroying the old one.
If false, the old node group will be destroyed first, causing downtime.
Changing this setting will always cause node group to be replaced.

Default value: true

metadata_http_put_response_hop_limit (number) optional

The desired HTTP PUT response hop limit (between 1 and 64) for Instance Metadata Service requests.
The default is 2 to allows containerized workloads assuming the instance profile, but it's not really recomended. You should use OIDC service accounts instead.

Default value: 2

metadata_http_tokens_required (bool) optional

Set true to require IMDS session tokens, disabling Instance Metadata Service Version 1.

Default value: true

module_depends_on (any) optional

Can be any value desired. Module will wait for this value to be computed before creating node group.

Default value: [ ]

node_role_cni_policy_enabled (bool) optional

When true, the AmazonEKS_CNI_Policy will be attached to the node IAM role.
This used to be required, but it is now recommended that this policy be
attached only to the aws-node Kubernetes service account. However, that
is difficult to do with Terraform, so this module defaults to the old pattern.

Note that this configures the launch template only. Some elements will be ignored by the Auto Scaling Group
that actually launches instances. Consult AWS documentation for details.

Default value: [ ]

random_pet_length (number) optional

In order to support "create before destroy" behavior, this module uses the random_pet
resource to generate a unique pet name for the node group, since the node group name
must be unique, meaning the new node group must have a different name than the old one.
This variable controls the length of the pet name, meaning the number of pet names
concatenated together. This module defaults to 1, but there are only 452 names available,
so users with large numbers of node groups may want to increase this value.

]

ssh_access_security_group_ids (list(string)) optional

Set of EC2 Security Group IDs to allow SSH access (port 22) to the worker nodes. If you specify ec2_ssh_key, but do not specify this configuration when you create an EKS Node Group, port 22 on the worker nodes is opened to the Internet (0.0.0.0/0)

Default value: [ ]

update_config (list(map(number))) optional

Configuration for the eks_node_group update_config Configuration Block.
Specify exactly one of max_unavailable (node count) or max_unavailable_percentage (percentage of nodes).

Default value: [ ]

userdata_override_base64 (list(string)) optional

Many features of this module rely on the bootstrap.sh provided with Amazon Linux, and this module
may generate "user data" that expects to find that script. If you want to use an AMI that is not
compatible with the userdata generated by this module, then use userdata_override_base64 to provide
your own (Base64 encoded) user data. Use "" to prevent any user data from being set.

Setting userdata_override_base64 disables kubernetes_taints, kubelet_additional_options,
before_cluster_joining_userdata, after_cluster_joining_userdata, and bootstrap_additional_options.

Default value: [ ]

Context Variables

The following variables are defined in the context.tf file of this module and part of the terraform-null-label pattern.

additional_tag_map (map(string)) optional

Additional key-value pairs to add to each map in tags_as_list_of_maps. Not added to tags or id.

Default value: lower.

Required: No

Default value: null

labels_as_tags (set(string)) optional

Set of labels (ID elements) to include as tags in the tags output.
Default is to include all labels.
Tags with empty values will not be included in the tags output.
