Creating Nodes from code?

Questions / Help

Hi,

i am trying to connect multiple nodes within elixir code but I gave up after trying multiple things.

node = :"main@127.0.0.1"
nodes_list = [:"n1@127.0.0.1", :"n2@127.0.0.1", :"n3@127.0.0.1", :"n4@127.0.0.1"]
Node.start(node)

Enum.each(nodes_list, fn node ->
   Node.connect(node)
end)

Node.list() # its always empty.

Is there a way that I can start these nodes from code and then run a binary on that node from code?

Thanks

Hi,
does Node.connect/1 return true in your Enum.each/2 function?
And how did you start the nodes you want to connect to?

That’s the issue am facing, I don’t know how to start nodes inside the module.
Of course Node.connect/1 will return false because no nodes are started yet.

No, that’s as far as I know not possible without getting really hacky (e.g. starting it with System.cmd/3).
Why do you need to spawn a new node from code?

There is :slave to spawn additional nodes.
