Kubernetes-v1.31

Infrastructure Update - Kubernetes 1.31 Deployment

🚀 What’s New

We have made the following updates to our Terraform codebase:

Kubernetes Version: Upgraded to v1.31

S3 Filestore Bucket: Filestore S3 bucket will be created automatically and filestore Secrets are now automatically created during infra creation.
By default, secrets are created in the egov namespace.

To change the namespace, update the namespace variable in variables.tf.

variable "filestore_namespace" {
  description = "Provide the namespace to create filestore secret"
  default = "egov" #REPLACE  
}

⚙️ Configuration Details

Instance Type: Default instance type is set to m5.xlarge

To Modify Configurations:
Update variables.tf to change instance type or to provide multiple instance types

variable "instance_types" {
  description = "Arry of instance types for SPOT instances"
  default = ["m5a.xlarge", "r5ad.xlarge", "m6a.xlarge"] 
}

Migrating from v1.30 to v1.31

🔧 Step 1: Update Kubernetes Version in variables.tf

Locate the kubernetes_version variable in your variables.tf file and update the version from 1.30 to 1.31.

variable "kubernetes_version" {
  description = "kubernetes version"
  default     = "1.31"
}

🛠️ Step 2: Remove Module Dependency to Prevent node IAM Role Updates

Before:

module "eks_managed_node_group" {
  depends_on = [module.eks]
  # other config...
}

After:

module "eks_managed_node_group" {
  # other config...
}

▶️ Step 3: Apply Terraform Changes

Run the following commands to initialize the provider, review the plan, and apply the upgrade:

terraform init
terraform plan
terraform apply

✅ Verification

After the upgrade completes:

Confirm the Kubernetes version using the AWS Console or CLI:

aws eks describe-cluster --name <your-cluster-name> --query "cluster.version"
