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 .

Tip

πŸ‘½ Use Atmos with Terraform

Cloud Posse uses atmos to easily orchestrate multiple environments using Terraform.
Works with Github Actions, Atlantis, or Spacelift.

Watch demo of using Atmos with Terraform
Example of running atmos to manage infrastructure from our Quick Start tutorial.

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:

  1. before_cluster_joining_userdata
  2. kubelet_additional_options
  3. bootstrap_additional_options
  4. 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.

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.

Important

In Cloud Posse's examples, we avoid pinning modules to specific versions to prevent discrepancies between the documentation and the latest released versions. However, for your own projects, we strongly advise pinning each module to the exact version you're using. This practice ensures the stability of your infrastructure. Additionally, we recommend implementing a systematic approach for updating versions to avoid unexpected changes.

Windows managed node-groups have a few pre-requisites.

  • Your cluster must contain at least one linux based worker node
  • Your EKS Cluster must have the AmazonEKSVPCResourceController and AmazonEKSClusterPolicy policies attached
  • Your cluster must have a config-map called amazon-vpc-cni with the following content
apiVersion: v1
kind: ConfigMap
metadata:
name: amazon-vpc-cni
namespace: kube-system
data:
enable-windows-ipam: "true"
  • Windows nodes will automatically be tainted
kubernetes_taints = [{
  key    = "WINDOWS"
  value  = "true"
  effect = "NO_SCHEDULE"
}]
  • Any pods that target Windows will need to have the following attributes set in their manifest
  nodeSelector:

string "AL2_x86_64" no
associate_cluster_security_group When true, associate the default cluster security group to the nodes. If disabled the EKS managed security group will not
be associated to the nodes and you will need to provide another security group that allows the nodes to communicate with
the EKS control plane. Be aware that if no associated_security_group_ids or ssh_access_security_group_ids are provided,
then the nodes will have no inbound or outbound rules.

no
cpu_options Configuration for the cpu_options Configuration Block of the launch template.
Leave list empty for defaults. Pass list with single object with attributes matching the cpu_options block to configure it.
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.
list(any) [] no
create_before_destroy 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.
bool true no
delimiter Delimiter to be used between ID elements.
Defaults to - (hyphen). Set to "" to use no delimiter at all.
string null no
descriptor_formats Describe additional descriptors to be output in the descriptors output map.
Map of maps. Keys are names of descriptors. Values are maps of the form
{<br/> format = string<br/> labels = list(string)<br/>}
(Type is any so the map values can later be enhanced to provide additional options.)
format is a Terraform format string to be passed to the format() function.
labels is a list of labels, in order, to pass to format() function.
Label values will be normalized before being passed to format() so they will be
identical to how they appear in id.

Set to 0 for unlimited length.
Set to null for keep the existing setting, which defaults to 0.
Does not affect id_full.
number null no
immediately_apply_lt_changes When true, any change to the launch template will be applied immediately.
When false, the changes will only affect new nodes when they are launched.
When null (default) this input takes the value of create_before_destroy.
NOTE: Setting this to false does not guarantee that other changes,
such as ami_type, will not cause changes to be applied immediately.
bool null no
instance_types Instance types to use for this node group (up to 20). Defaults to ["t3.medium"].
Must be empty if the launch template configured by launch_template_id specifies an instance type.
list(string)
[

Possible values: lower, title, upper.
Default value: title.
string null no
label_order The order in which the labels (ID elements) appear in the id.
Defaults to ["namespace", "environment", "stage", "name", "attributes"].
You can omit any of the 6 labels ("tenant" is the 6th), but at least one must be present.
list(string) null no
label_value_case Controls the letter case of ID elements (labels) as included in id,
set as tag values, and output by this module individually.
Does not affect values of tags passed in via the tags input.
Possible values: lower, title, upper and none (no transformation).
Set this to title and set delimiter to "" to yield Pascal Case IDs.
Default value: lower.
string null no
labels_as_tags 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.
Set to [] to suppress all generated tags.
Notes:
The value of the name tag, if included, will be the id, not the name.
Unlike other null-label inputs, the initial setting of labels_as_tags cannot be
changed in later chained modules. Attempts to change it will be silently ignored.
set(string)
[
"default"
]
no
launch_template_id The ID (not name) of a custom launch template to use for the EKS node group. If provided, it must specify the AMI image ID. list(string) [] no
launch_template_version The version of the specified launch template to use. Defaults to latest version. list(string) [] no

metadata_http_put_response_hop_limit 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.
number 2 no
metadata_http_tokens_required Set true to require IMDS session tokens, disabling Instance Metadata Service Version 1. bool true no
min_size Minimum number of worker nodes number n/a yes
module_depends_on Can be any value desired. Module will wait for this value to be computed before creating node group. any null no
name ID element. Usually the component or solution name, e.g. 'app' or 'jenkins'.

update = optional(string)
delete = optional(string)
}))
[] no
node_role_arn If provided, assign workers the given role, which this module will not modify list(string) [] no
node_role_cni_policy_enabled 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.
bool true no
node_role_permissions_boundary If provided, all IAM roles will be created with this permissions boundary attached. string null no
node_role_policy_arns List of policy ARNs to attach to the worker role this module creates in addition to the default ones list(string) [] no
placement Configuration for the placement Configuration Block of the launch template.
Leave list empty for defaults. Pass list with single object with attributes matching the placement block to configure it.
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.
list(any) [] no
random_pet_length 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.
number 1 no
regex_replace_chars Terraform regular expression (regex) string.
Characters matching the regex will be removed from the ID elements.
If not set, "/[^a-zA-Z0-9-]/" is used to remove all characters other than hyphens, letters and digits.
string null no
replace_node_group_on_version_update Force Node Group replacement when updating to a new Kubernetes version. If set to false (the default), the Node Groups will be updated in-place bool false no
resources_to_tag List of auto-launched resource types to tag. Valid types are "instance", "volume", "elastic-gpu", "spot-instances-request", "network-interface". list(string)
[
"instance",
"volume",
"network-interface"
]
no
ssh_access_security_group_ids 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) list(string) [] no
stage ID element. Usually used to indicate role, e.g. 'prod', 'staging', 'source', 'build', 'test', 'deploy', 'release' string null no
subnet_ids A list of subnet IDs to launch resources in list(string) n/a yes
tags Additional tags (e.g. {'BusinessUnit': 'XYZ'}).
Neither the tag keys nor the tag values will be modified by this module.
map(string) {} no
tenant ID element _(Rarely used, not included by default)_. A customer identifier, indicating who this instance of a resource is for string null no
update_config 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).
list(map(number)) [] no
userdata_override_base64 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.
list(string) [] no
