no eksctl-managed CloudFormation stacks found > Error: loading VPC spec for cluster,

I have created EKS cluster manually. Now when I am trying to create a nodegroup for Windows by following this link launch-windows-workers

I am getting this below error:-

2021-09-03 06:28:02 [!] no eksctl-managed CloudFormation stacks found for "testEnv-cluster", will attempt to create nodegroup(s) on non eksctl-managed cluster Error: loading VPC spec for cluster "testEnv-cluster": VPC configuration required for creating nodegroups on clusters not owned by eksctl: vpc.subnets, vpc.id, vpc.securityGroup

  1. How do I own this cluster for eksctl which was earlier manually created by eks and then following process was accomplished by kubectl ?
  2. How do I create node-group for Windows instance under my cluster ?
  3. How to create the cloudformation stack for the Windows NodeGroup ?

any help

How do I own this cluster for eksctl which was earlier manually created by eks and then following process was accomplished by kubectl ?

You can create node group even in a cluster not created by eksctl. However, since eksctl can't fetch cluster info from CloudFormation, you need to manually input network configuration in ClusterConfig.

Here's an example from the official document See this link for further detail.

vpc:
  id: "vpc-12345"
  securityGroup: "sg-12345"    # this is the ControlPlaneSecurityGroup
  subnets:
    private:
      private1:
          id: "subnet-12345"
      private2:
          id: "subnet-67890"
    public:
      public1:
          id: "subnet-12345"
      public2:
          id: "subnet-67890"

How do I create node-group for Windows instance under my cluster ? How to create the cloudformation stack for the Windows NodeGroup ?

You can create managed or self-managed node group using eksctl by adding node groups with amiFamily: WindowsServer2019FullContainer or other Windows AMIs. eksctl will automatically created a Cloudformation stack for each node group.

Here's an example from the official document

managedNodeGroups:
  - name: windows-managed-ng
    amiFamily: WindowsServer2019FullContainer
    minSize: 2
    maxSize: 3
