  -c, --cluster-id ${COLOR_YELLOW}CLUSTER_ID${TEXT_RESET}          Cluster ID

  --efs-csi-driver-role-arn ${COLOR_YELLOW}EFS_CSI_DRIVER_ROLE_ARN${TEXT_RESET}    ARN of the IAM Role to assign to the EFS CSI driver

Automatic GitHub Push (Optional):
  -P, --github-push ${COLOR_YELLOW}GITHUB_PUSH${TEXT_RESET}        Enable automatic push to GitHub
  -H, --github-host ${COLOR_YELLOW}GITHUB_HOST${TEXT_RESET}        GitHub Hostname for your GitOps repository
  -O, --github-org ${COLOR_YELLOW}GITHUB_ORG${TEXT_RESET}          Github org for your GitOps repository
  -R, --github-repo ${COLOR_YELLOW}GITHUB_REPO${TEXT_RESET}        Github repo for your GitOps repository
  -S, --github-ssh ${COLOR_YELLOW}GIT_SSH${TEXT_RESET}             Git ssh key path
  -B, --git-branch ${COLOR_YELLOW}GIT_BRANCH${TEXT_RESET}          Git branch to commit to of your GitOps repository
