This article explains about Elixir Module Deployment across multiple nodes from the scratch. Here, we go with deep understanding of things like Node Creation, Establishing Node Connection, and Deploying Modules across multiple Nodes.

First we go with module creation which will be shared across the Nodes.

Module Creation

Here we create an Elixir Module with filename my_node.ex and with convention we name our module as MyNode.

Create a file using your favorite editor. Here I am using vim .

$ vim mynode.ex

After creating the file copy the following code snippet and paste it inside the file mynode.ex.

defmodule MyNode do
  def hello do
    IO.puts "hi !! #{Node.self()}"
  end
end

The code snippet contains a function MyNode.hello/0 and this function will greet you with hi !! and node name form where you are calling this function. The Node.self() returns the current node.

After creating a file, compile the file with following command…

$ elixirc mynode.ex
