      eks_node_quantity: 0
      eks_node_max_quantity: 30
      eks_node_min_quantity: 0
      eks_node_disk_size: 500
      eks_node_instance_type: "g4dn.12xlarge"
      use_gpu_ami: True
      eks_node_labels:
        usage: g4dn.12xlarge

          yum install nvme-cli -y

          # Get list of NVMe Drives
          nvme_drives=$(nvme list | grep "Amazon EC2 NVMe Instance Storage" | cut -d " " -f 1 || true)
          readarray -t nvme_drives <<< "$nvme_drives"
          'num_drives=1'
          # Install software RAID utility
          yum install mdadm -y

          # Create RAID-0 array across the instance store NVMe SSDs
         'mdadm --create /dev/md0 --level=0 --name=md0 --raid-devices=$num_drives "${nvme_drives[@]}"'
          # Format drive with Ext4
          mkfs.ext4 /dev/md0

          # Get RAID array's UUID
          uuid=$(blkid -o value -s UUID /dev/md0)

          # Create a filesystem path to mount the disk
          mount_location="/mnt/fast-disks/${uuid}"
          mkdir -p $mount_location

          # Mount RAID device
          mount /dev/md0 $mount_location

          # Have disk be mounted on reboot
          mdadm --detail --scan >> /etc/mdadm.conf 
          echo /dev/md0 $mount_location ext4 defaults,noatime 0 2 >> /etc/fstab

• supports nested parameters such as frequently used in idf/compute/eks module
• add test cases
• update docs

Usage:

name: test-module-1
path: modules/test-module
targetAccount: primary
targetRegion: us-west-2
parameters:
  - name: param1
    disableEnvVarResolution: True
    value:
      - |
        export VAR=test
        echo "${VAR}"
