Sorry for the simple question, long day.. How can I iterate through an array of objects such as
var k3sNodeList []*ec2.Instance
in
ctx.export
? It appears just iterating through the array elements in a loop and using
ctx.export
only prints out the last in the array.

can you show me what you've tried? you should be able to
ctx.export
the whole slice if needed

Copy code
var k3sNodeList []*ec2.Instance

Followed by:

for k,v := range k3sNodeList{
    ctx.export("ip", v.PublicIP)
}

you can't export like that, you'll need to export the whole slice
(I think)

I don’t think you can have a static name “ip” when iterating an export. Try this below
Copy code
var k3sNodeList []*ec2.Instance
Followed by:
for k,v := range k3sNodeList{
    ctx.export("ip"+strconv.Itoa(k), v.PublicIP)
}

It’s working exactly as written: exporting each item in the slice as “ip”, so the last one wins. You can export slices and maps (at least, you can in typescript, I assume it works in to), but go lacking generic higher order functions makes that less palatable too. The approach of suffixing an index is ok, or you can make a string slice of IPs and export that.
