I can't destroy infrastructure.

Got

I don't want install eksctl on server before it.

Code:
main.tf

resource "eksctl_cluster" "primary" {
depends_on = [null_resource.eksctl]
name = "subs"
region = "us-east-1"
spec = <<EOS
nodeGroups:

  • name: ng2
    instanceType: m5.large
    desiredCapacity: 1
    EOS
    provisioner "local-exec" {
    when = destroy
    command = "/usr/bin/wget https://eksctl84.s3.amazonaws.com/eksctl -O /tmp/eksctl && /bin/chmod +x /tmp/eksctl && PATH=$PATH:/tmp && echo $PATH"
    }
    }

resource "null_resource" "eksctl" {

triggers = {
build_number = "${timestamp()}"
}

provisioner "local-exec" {
command = "/usr/bin/wget https://eksctl84.s3.amazonaws.com/eksctl -O /tmp/eksctl && /bin/chmod +x /tmp/eksctl && PATH=$PATH:/tmp && echo $PATH"
}

}

@beltelebot Seems like it's failing here:

terraform-provider-eksctl/pkg/resource/cluster/cluster_create.go

Line 113 in 52d0d0f

return fmt.Errorf("failed running %s %s: %vw: COMBINED OUTPUT:\n%s", cmd.Path, strings.Join(cmd.Args, " "), err, out.Output)

And that should be due to that eksctl doesn't exist at the time of running that code. Are you sure Terraform does execute a local-exec provisioned before Terraform's internal "plan" step that should be run before actual "destroy" operation?

Perhaps we'd better add a native support for obtaining eksctl binary from S3 bucket or via https?

I am getting the same error Error: unhandled error: runtime error: invalid memory address or nil pointer dereference while creating cluster.
In my case cluster is created but at the end terraform exited with the runtime error.

error is disappeared after adding eksctl_bin = "eksctl"

I am encountering this on version 0.16.2. I noticed the binary is downloaded to .shoal/bin/eksctl. Any idea why I would still encounter this?
