AWS is no longer adding new features back into launch configuration and their docs state <code>We strongly recommend that you do not use launch configurations. They do not provide full functionality for Amazon EC2 Auto Scaling or Amazon EC2. We provide information about launch configurations for customers who have not yet migrated from launch configurations to launch templates.</code></li> <li>Support for managing aws-auth configmap has been removed. This change also removes the dependency on the Kubernetes Terraform provider, the local dependency on aws-iam-authenticator for users, as well as the reliance on the forked http provider to wait and poll on cluster creation. To aid users in this change, an output variable <code>aws_auth_configmap_yaml</code> has been provided which renders the aws-auth configmap necessary to support at least the IAM roles used by the module (additional mapRoles/mapUsers definitions to be provided by users)</li> <li>Support for managing kubeconfig and its associated <code>local_file</code> resources have been removed; users are able to use the awscli provided <code>aws eks update-kubeconfig --name &lt;cluster_name&gt;</code> to update their local kubeconfig as necessary</li> <li>The terminology used in the module has been modified to reflect that used by the AWS documentation.</li> <li>AWS EKS Managed Node Group, <code>eks_managed_node_groups</code>, was previously referred to as simply node group, <code>node_groups</code></li> <li>Self Managed Node Group Group, <code>self_managed_node_groups</code>, was previously referred to as worker group, <code>worker_groups</code></li> <li>AWS Fargate Profile, <code>fargate_profiles</code>, remains unchanged in terms of naming and terminology</li> <li>The three different node group types supported by AWS and the module have been refactored into standalone sub-modules that are both used by the root <code>eks</code> module as well as available for individual, standalone consumption if desired.</li> <li>The previous <code>node_groups</code> sub-module is now named <code>eks-managed-node-group</code> and provisions a single AWS EKS Managed Node Group per sub-module definition (previous version utilized <code>for_each</code> to create 0 or more node groups)<ul> <li>Additional changes for the <code>eks-managed-node-group</code> sub-module over the previous <code>node_groups</code> module include:</li> <li>Variable name changes defined in section <code>Variable and output changes</code> below</li> <li>Support for nearly full control of the IAM role created, or provide the ARN of an existing IAM role, has been added</li> <li>Support for nearly full control of the security group created, or provide the ID of an existing security group, has been added</li> <li>User data has been revamped and all user data logic moved to the <code>_user_data</code> internal sub-module; the local <code>userdata.sh.tpl</code> has been removed entirely</li> </ul> </li> <li>The previous <code>fargate</code> sub-module is now named <code>fargate-profile</code> and provisions a single AWS EKS Fargate Profile per sub-module definition (previous version utilized <code>for_each</code> to create 0 or more profiles)<ul> <li>Additional changes for the <code>fargate-profile</code> sub-module over the previous <code>fargate</code> module include:</li> <li>Variable name changes defined in section <code>Variable and output changes</code> below</li> <li>Support for nearly full control of the IAM role created, or provide the ARN of an existing IAM role, has been added</li> <li>Similar to the <code>eks_managed_node_group_defaults</code> and <code>self_managed_node_group_defaults</code>, a <code>fargate_profile_defaults</code> has been provided to allow users to control the default configurations for the Fargate profiles created</li> </ul> </li> <li>A sub-module for <code>self-managed-node-group</code> has been created and provisions a single self managed node group (autoscaling group) per sub-module definition<ul> <li>Additional changes for the <code>self-managed-node-group</code> sub-module over the previous <code>node_groups</code> variable include:</li> <li>The underlying autoscaling group and launch template have been updated to more closely match that of the <code>terraform-aws-autoscaling</code> module and the features it offers</li> <li>The previous iteration used a count over a list of node group definitions which was prone to disruptive updates; this is now replaced with a map/for_each to align with that of the EKS managed node group and Fargate profile behaviors/style</li> </ul> </li> <li>The user data configuration supported across the module has been completely revamped. A new <code>_user_data</code> internal sub-module has been created to consolidate all user data configuration in one location which provides better support for testability (via the <code>tests/user-data</code> example). The new sub-module supports nearly all possible combinations including the ability to allow users to provide their own user data template which will be rendered by the module. See the <code>tests/user-data</code> example project for the full plethora of example configuration possibilities and more details on the logic of the design can be found in the <code>modules/_user_data</code> directory.</li> <li>Resource name changes may cause issues with existing resources. For example, security groups and IAM roles cannot be renamed, they must be recreated. Recreation of these resources may also trigger a recreation of the cluster. To use the legacy (&lt; 18.x) resource naming convention, set <code>prefix_separator</code> to \"\".</li> <li>Security group usage has been overhauled to provide only the bare minimum network connectivity required to launch a bare bones cluster. See the security group documentation section for more details. Users upgrading to v18.x will want to review the rules they have in place today versus the rules provisioned by the v18.x module and ensure to make any necessary adjustments for their specific workload.</li> </ul>"},{"location":"UPGRADE-18.0/#additional-changes","title":"Additional changes","text":""},{"location":"UPGRADE-18.0/#added","title":"Added","text":"<ul> <li>Support for AWS EKS Addons has been added</li> <li>Support for AWS EKS Cluster Identity Provider Configuration has been added</li> <li>AWS Terraform provider minimum required version has been updated to 3.64 to support the changes made and additional resources supported</li> <li>An example <code>user_data</code> project has been added to aid in demonstrating, testing, and validating the various methods of configuring user data with the <code>_user_data</code> sub-module as well as the root <code>eks</code> module</li> <li>Template for rendering the aws-auth configmap output - <code>aws_auth_cm.tpl</code></li> <li>Template for Bottlerocket OS user data bootstrapping - <code>bottlerocket_user_data.tpl</code></li> </ul>"},{"location":"UPGRADE-18.0/#modified","title":"Modified","text":"<ul> <li>The previous <code>fargate</code> example has been renamed to <code>fargate_profile</code></li> <li>The previous <code>irsa</code> and <code>instance_refresh</code> examples have been merged into one example <code>irsa_autoscale_refresh</code></li> <li>The previous <code>managed_node_groups</code> example has been renamed to <code>self_managed_node_group</code></li> <li>The previously hardcoded EKS OIDC root CA thumbprint value and variable has been replaced with a <code>tls_certificate</code> data source that refers to the cluster OIDC issuer url.

This is due to the fact that the cluster name is a unique constraint and therefore its set as the unique identifier within Terraform's state map. However, starting with local EKS clusters created on Outposts, there is now an attribute returned from the <code>aws eks create-cluster</code> API named <code>id</code>. The <code>cluster_id</code> has been updated to return this value which means that for current, standard EKS clusters created in the AWS cloud, no value will be returned (at the time of this writing) for <code>cluster_id</code> and only local EKS clusters on Outposts will return a value that looks like a UUID/GUID. Users should switch all instances of <code>cluster_id</code> to use <code>cluster_name</code> before upgrading to v19. Reference</li> <li>Minimum supported version of Terraform AWS provider updated to v4.45 to support the latest features provided via the resources utilized.</li> <li>Minimum supported version of Terraform updated to v1.0</li> <li>Individual security group created per EKS managed node group or self-managed node group has been removed. This configuration went mostly unused and would often cause confusion (\"Why is there an empty security group attached to my nodes?\"). This functionality can easily be replicated by user's providing one or more externally created security groups to attach to nodes launched from the node group.</li> <li>Previously, <code>var.iam_role_additional_policies</code> (one for each of the following: cluster IAM role, EKS managed node group IAM role, self-managed node group IAM role, and Fargate Profile IAM role) accepted a list of strings. This worked well for policies that already existed but failed for policies being created at the same time as the cluster due to the well-known issue of unknown values used in a <code>for_each</code> loop. To rectify this issue in <code>v19.x</code>, two changes were made:</li> <li><code>var.iam_role_additional_policies</code> was changed from type <code>list(string)</code> to type <code>map(string)</code> -&gt; this is a breaking change. More information on managing this change can be found below, under <code>Terraform State Moves</code></li> <li>The logic used in the root module for this variable was changed to replace the use of <code>try()</code> with <code>lookup()</code>. More details on why can be found here</li> <li>The cluster name has been removed from the Karpenter module event rule names. Due to the use of long cluster names appending to the provided naming scheme, the cluster name has moved to a <code>ClusterName</code> tag and the event rule name is now a prefix. This guarantees that users can have multiple instances of Karpenter with their respective event rules/SQS queue without name collisions, while also still being able to identify which queues and event rules belong to which cluster.</li> <li>The new variable <code>node_security_group_enable_recommended_rules</code> is set to true by default and may conflict with any custom ingress/egress rules. Please ensure that any duplicates from the <code>node_security_group_additional_rules</code> are removed before upgrading, or set <code>node_security_group_enable_recommended_rules</code> to false.

This on its own does not cause any conflicts for addons such as the AWS Load Balancer Controller until users decide to attach both the cluster primary security group and the shared node security group created by the module (by setting <code>attach_cluster_primary_security_group = true</code>). The issue is not with having multiple security groups in your account with this tag key:value combination, but having multiple security groups with this tag key:value combination attached to nodes in the same cluster. There are a few ways to resolve this depending on your use case/intentions:</p> <ol> <li>If you want to use the cluster primary security group, you can disable the creation of the shared node security group with:</li> </ol> <pre><code>  create_node_security_group = false # default is true\n\n  eks_managed_node_group = {\n    example = {\n      attach_cluster_primary_security_group = true # default is false\n    }\n  }\n  # Or for self-managed\n  self_managed_node_group = {\n    example = {\n      attach_cluster_primary_security_group = true # default is false\n    }\n  }\n</code></pre> <ol> <li>By not attaching the cluster primary security group. The cluster primary security group has quite broad access and the module has instead provided a security group with the minimum amount of access to launch an empty EKS cluster successfully and users are encouraged to open up access when necessary to support their workload.</li> </ol> <pre><code>  eks_managed_node_group = {\n    example = {\n      attach_cluster_primary_security_group = true # default is false\n    }\n  }\n  # Or for self-managed\n  self_managed_node_group = {\n    example = {\n      attach_cluster_primary_security_group = true # default is false\n    }\n  }\n</code></pre> <p>In theory, if you are attaching the cluster primary security group, you shouldn't need to use the shared node security group created by the module.

AWS is no longer adding new features back into launch configuration and their docs state <code>We strongly recommend that you do not use launch configurations. They do not provide full functionality for Amazon EC2 Auto Scaling or Amazon EC2. We provide information about launch configurations for customers who have not yet migrated from launch configurations to launch templates.</code></li> <li>Support for managing aws-auth configmap has been removed. This change also removes the dependency on the Kubernetes Terraform provider, the local dependency on aws-iam-authenticator for users, as well as the reliance on the forked http provider to wait and poll on cluster creation. To aid users in this change, an output variable <code>aws_auth_configmap_yaml</code> has been provided which renders the aws-auth configmap necessary to support at least the IAM roles used by the module (additional mapRoles/mapUsers definitions to be provided by users)</li> <li>Support for managing kubeconfig and its associated <code>local_file</code> resources have been removed; users are able to use the awscli provided <code>aws eks update-kubeconfig --name &lt;cluster_name&gt;</code> to update their local kubeconfig as necessary</li> <li>The terminology used in the module has been modified to reflect that used by the AWS documentation.</li> <li>AWS EKS Managed Node Group, <code>eks_managed_node_groups</code>, was previously referred to as simply node group, <code>node_groups</code></li> <li>Self Managed Node Group Group, <code>self_managed_node_groups</code>, was previously referred to as worker group, <code>worker_groups</code></li> <li>AWS Fargate Profile, <code>fargate_profiles</code>, remains unchanged in terms of naming and terminology</li> <li>The three different node group types supported by AWS and the module have been refactored into standalone sub-modules that are both used by the root <code>eks</code> module as well as available for individual, standalone consumption if desired.</li> <li>The previous <code>node_groups</code> sub-module is now named <code>eks-managed-node-group</code> and provisions a single AWS EKS Managed Node Group per sub-module definition (previous version utilized <code>for_each</code> to create 0 or more node groups)<ul> <li>Additional changes for the <code>eks-managed-node-group</code> sub-module over the previous <code>node_groups</code> module include:</li> <li>Variable name changes defined in section <code>Variable and output changes</code> below</li> <li>Support for nearly full control of the IAM role created, or provide the ARN of an existing IAM role, has been added</li> <li>Support for nearly full control of the security group created, or provide the ID of an existing security group, has been added</li> <li>User data has been revamped and all user data logic moved to the <code>_user_data</code> internal sub-module; the local <code>userdata.sh.tpl</code> has been removed entirely</li> </ul> </li> <li>The previous <code>fargate</code> sub-module is now named <code>fargate-profile</code> and provisions a single AWS EKS Fargate Profile per sub-module definition (previous version utilized <code>for_each</code> to create 0 or more profiles)<ul> <li>Additional changes for the <code>fargate-profile</code> sub-module over the previous <code>fargate</code> module include:</li> <li>Variable name changes defined in section <code>Variable and output changes</code> below</li> <li>Support for nearly full control of the IAM role created, or provide the ARN of an existing IAM role, has been added</li> <li>Similar to the <code>eks_managed_node_group_defaults</code> and <code>self_managed_node_group_defaults</code>, a <code>fargate_profile_defaults</code> has been provided to allow users to control the default configurations for the Fargate profiles created</li> </ul> </li> <li>A sub-module for <code>self-managed-node-group</code> has been created and provisions a single self managed node group (autoscaling group) per sub-module definition<ul> <li>Additional changes for the <code>self-managed-node-group</code> sub-module over the previous <code>node_groups</code> variable include:</li> <li>The underlying autoscaling group and launch template have been updated to more closely match that of the <code>terraform-aws-autoscaling</code> module and the features it offers</li> <li>The previous iteration used a count over a list of node group definitions which was prone to disruptive updates; this is now replaced with a map/for_each to align with that of the EKS managed node group and Fargate profile behaviors/style</li> </ul> </li> <li>The user data configuration supported across the module has been completely revamped. A new <code>_user_data</code> internal sub-module has been created to consolidate all user data configuration in one location which provides better support for testability (via the <code>tests/user-data</code> example). The new sub-module supports nearly all possible combinations including the ability to allow users to provide their own user data template which will be rendered by the module. See the <code>tests/user-data</code> example project for the full plethora of example configuration possibilities and more details on the logic of the design can be found in the <code>modules/_user_data</code> directory.</li> <li>Resource name changes may cause issues with existing resources. For example, security groups and IAM roles cannot be renamed, they must be recreated. Recreation of these resources may also trigger a recreation of the cluster. To use the legacy (&lt; 18.x) resource naming convention, set <code>prefix_separator</code> to \"\".</li> <li>Security group usage has been overhauled to provide only the bare minimum network connectivity required to launch a bare bones cluster. See the security group documentation section for more details. Users upgrading to v18.x will want to review the rules they have in place today versus the rules provisioned by the v18.x module and ensure to make any necessary adjustments for their specific workload.</li> </ul>"},{"location":"UPGRADE-18.0.html#additional-changes","title":"Additional changes","text":""},{"location":"UPGRADE-18.0.html#added","title":"Added","text":"<ul> <li>Support for AWS EKS Addons has been added</li> <li>Support for AWS EKS Cluster Identity Provider Configuration has been added</li> <li>AWS Terraform provider minimum required version has been updated to 3.64 to support the changes made and additional resources supported</li> <li>An example <code>user_data</code> project has been added to aid in demonstrating, testing, and validating the various methods of configuring user data with the <code>_user_data</code> sub-module as well as the root <code>eks</code> module</li> <li>Template for rendering the aws-auth configmap output - <code>aws_auth_cm.tpl</code></li> <li>Template for Bottlerocket OS user data bootstrapping - <code>bottlerocket_user_data.tpl</code></li> </ul>"},{"location":"UPGRADE-18.0.html#modified","title":"Modified","text":"<ul> <li>The previous <code>fargate</code> example has been renamed to <code>fargate_profile</code></li> <li>The previous <code>irsa</code> and <code>instance_refresh</code> examples have been merged into one example <code>irsa_autoscale_refresh</code></li> <li>The previous <code>managed_node_groups</code> example has been renamed to <code>self_managed_node_group</code></li> <li>The previously hardcoded EKS OIDC root CA thumbprint value and variable has been replaced with a <code>tls_certificate</code> data source that refers to the cluster OIDC issuer url.

This is due to the fact that the cluster name is a unique constraint and therefore its set as the unique identifier within Terraform's state map. However, starting with local EKS clusters created on Outposts, there is now an attribute returned from the <code>aws eks create-cluster</code> API named <code>id</code>. The <code>cluster_id</code> has been updated to return this value which means that for current, standard EKS clusters created in the AWS cloud, no value will be returned (at the time of this writing) for <code>cluster_id</code> and only local EKS clusters on Outposts will return a value that looks like a UUID/GUID. Users should switch all instances of <code>cluster_id</code> to use <code>cluster_name</code> before upgrading to v19. Reference</li> <li>Minimum supported version of Terraform AWS provider updated to v4.45 to support the latest features provided via the resources utilized.</li> <li>Minimum supported version of Terraform updated to v1.0</li> <li>Individual security group created per EKS managed node group or self-managed node group has been removed. This configuration went mostly unused and would often cause confusion (\"Why is there an empty security group attached to my nodes?\"). This functionality can easily be replicated by user's providing one or more externally created security groups to attach to nodes launched from the node group.</li> <li>Previously, <code>var.iam_role_additional_policies</code> (one for each of the following: cluster IAM role, EKS managed node group IAM role, self-managed node group IAM role, and Fargate Profile IAM role) accepted a list of strings. This worked well for policies that already existed but failed for policies being created at the same time as the cluster due to the well-known issue of unknown values used in a <code>for_each</code> loop. To rectify this issue in <code>v19.x</code>, two changes were made:</li> <li><code>var.iam_role_additional_policies</code> was changed from type <code>list(string)</code> to type <code>map(string)</code> -&gt; this is a breaking change. More information on managing this change can be found below, under <code>Terraform State Moves</code></li> <li>The logic used in the root module for this variable was changed to replace the use of <code>try()</code> with <code>lookup()</code>. More details on why can be found here</li> <li>The cluster name has been removed from the Karpenter module event rule names. Due to the use of long cluster names appending to the provided naming scheme, the cluster name has moved to a <code>ClusterName</code> tag and the event rule name is now a prefix. This guarantees that users can have multiple instances of Karpenter with their respective event rules/SQS queue without name collisions, while also still being able to identify which queues and event rules belong to which cluster.</li> <li>The new variable <code>node_security_group_enable_recommended_rules</code> is set to true by default and may conflict with any custom ingress/egress rules. Please ensure that any duplicates from the <code>node_security_group_additional_rules</code> are removed before upgrading, or set <code>node_security_group_enable_recommended_rules</code> to false.

Since this sub-module is captured in the v20.x releases, users can continue using it even after the module moves forward with the next major version. The long term strategy and direction is cluster access entry and to rely only on the AWS Terraform provider.</li> <li>The default value for <code>authentication_mode</code> will change to <code>API</code>. Aligning with point 1 above, this is a one way change, but users are free to specify the value of their choosing in place of this default (when the change is made). This module will proceed with an EKS API first strategy.</li> <li>The launch template and autoscaling group usage contained within the EKS managed node group and self-managed node group sub-modules *might be replaced with the <code>terraform-aws-autoscaling</code> module. At minimum, it makes sense to replace most of functionality in the self-managed node group module with this external module, but its not yet clear if there is any benefit of using it in the EKS managed node group sub-module. The interface that users interact with will stay the same, the changes will be internal to the implementation and we will do everything we can to keep the disruption to a minimum.</li> <li>The <code>platform</code> variable will be replaced and instead <code>ami_type</code> will become the standard across both self-managed node group(s) and EKS managed node group(s). As EKS expands its portfolio of supported operating systems, the <code>ami_type</code> is better suited to associate the correct user data format to the respective OS. The <code>platform</code> variable is a legacy artifact of self-managed node groups but not as descriptive as the <code>ami_type</code>, and therefore it will be removed in favor of <code>ami_type</code>.</li> </ol>"},{"location":"UPGRADE-20.0.html#additional-changes","title":"Additional changes","text":""},{"location":"UPGRADE-20.0.html#added","title":"Added","text":"<ul> <li>A module tag has been added to the cluster control plane</li> <li>Support for cluster access entries.

Instead, users can enable/disable <code>enable_cluster_creator_admin_permissions</code> at any time to achieve the same functionality. This takes the identity that Terraform is using to make API calls and maps it into a cluster admin via an access entry.

This on its own does not cause any conflicts for addons such as the AWS Load Balancer Controller until users decide to attach both the cluster primary security group and the shared node security group created by the module (by setting <code>attach_cluster_primary_security_group = true</code>). The issue is not with having multiple security groups in your account with this tag key:value combination, but having multiple security groups with this tag key:value combination attached to nodes in the same cluster. There are a few ways to resolve this depending on your use case/intentions:</p> <ol> <li>If you want to use the cluster primary security group, you can disable the creation of the shared node security group with:</li> </ol> <pre><code>  create_node_security_group = false # default is true\n\n  eks_managed_node_group = {\n    example = {\n      attach_cluster_primary_security_group = true # default is false\n    }\n  }\n  # Or for self-managed\n  self_managed_node_group = {\n    example = {\n      attach_cluster_primary_security_group = true # default is false\n    }\n  }\n</code></pre> <ol> <li>By not attaching the cluster primary security group. The cluster primary security group has quite broad access and the module has instead provided a security group with the minimum amount of access to launch an empty EKS cluster successfully and users are encouraged to open up access when necessary to support their workload.</li> </ol> <pre><code>  eks_managed_node_group = {\n    example = {\n      attach_cluster_primary_security_group = true # default is false\n    }\n  }\n  # Or for self-managed\n  self_managed_node_group = {\n    example = {\n      attach_cluster_primary_security_group = true # default is false\n    }\n  }\n</code></pre> <p>In theory, if you are attaching the cluster primary security group, you shouldn't need to use the shared node security group created by the module.
