How to connect nodes of two docker containers in elixir?

Question

I am trying to connect 2 nodes of different docker containers.

Container1: iex --name [email protected] --cookie foo

Container2: iex --name [email protected] --cookie foo

Now lets say I want to connect to [email protected] from [email protected]

Container2:

iex([email protected])> Node.connect(:"[email protected]")

iex([email protected])> true

Nodes are getting connected. But if I do

iex([email protected])> node  = "[email protected]"

iex([email protected])> Node.connect(:node)

iex([email protected])> false

Why I am getting error? This is happening with other functions as well such as Node.spawn/2.

Answer 1

I got it working by converting the string into atom.

iex([email protected])> node  = "[email protected]"

iex([email protected])> Node.connect(String.to_atom(node))

iex([email protected])> true
