To create Terraform code for an EKS cluster, we need to define resources for the EKS cluster, node groups, IAM roles, security groups, and any necessary variables and outputs. The provided file-level summaries give us a good starting point, but we need to ensure that the resources are defined correctly and that they reference each other properly. We also need to ensure that the variables are defined with the correct default values and types, and that the outputs provide useful information for the user after the cluster is created.
provider.tf: Define the AWS provider and the AWS region variable. Ensure that the provider version is compatible with the EKS resources we are going to create.
variables.tf: Define all necessary variables such as cluster_name
, kubernetes_version
, node_group_name
, instance_types
, desired_count
, min_count
, max_count
, vpc_id
, and subnet_ids
. Make sure to provide descriptions and sensible default values where applicable.
security_groups.tf: Define security groups for the EKS cluster and node groups. Ensure that the rules allow for proper communication between the control plane and the node groups, as well as SSH access if necessary.
eks_node_group.tf: Define the EKS node group resource, referencing the variables for the cluster name, node group name, instance types, and subnet IDs. Include scaling configuration and any optional settings like AMI type, remote access, labels, or taints.
outputs.tf: Define outputs for the EKS cluster ID, endpoint, security group ID, certificate authority data, IAM role ARN for the node group, and node group status.
eks_cluster.tf: Define the EKS cluster resource, including the name, version, IAM role, VPC configuration, and logging. Reference the security group if necessary and ensure that the IAM role is defined in the iam_roles.tf
file.
iam_roles.tf: Define IAM roles for the EKS cluster and node groups, and attach the necessary policies to these roles. Include roles for Fargate if applicable.
After implementing these files, run terraform init
to initialize the Terraform configuration and terraform apply
to create the resources in AWS. Make sure to review and test the configuration to ensure that all resources are created as expected and that the cluster functions correctly.
