Terraform module to provision a fully managed AWS 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 . > [!TIP] > #### 👽 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
