Running command on multiple servers

Questions / Help
1

How do I run a function on multiple servers that contain my variable?

Ex:
I need to run this command on several servers.

server = ["server1com", "server2com", "server3com"]
{:ok, conn} = SSHEx.connect ip: '#{server}', user: 'myuser'
SSHEx.cmd! conn, 'mkdir -p /path/to/newdir'

How do I put this command in a loop, until the server list runs out?

Would it be this?
Note: It doesn’t work for me.

server = ["server1com", "server2com", "server3com"]
Enum.each(server, fn(_x) ->
 {:ok, conn} = SSHEx.connect ip: '#{server}', user: 'myuser'
 SSHEx.cmd! conn, 'mkdir -p /path/to/newdir'
end)

    for i <- server do
    end
