Build a Two Node Cluster

How do we join two nodes together in a single cluster?

Start the first node "lasp1".

If your Erlang system is configured to use only fully qualified host names, then in both of the following commands, replace "@localhost" with "@`hostname`"
where "hostname" is surrounded by backticks.

$ ./rebar3 shell --apps lasp --name lasp1@localhost

Start the second node "lasp2".

$ ./rebar3 shell --apps lasp --name lasp2@localhost

Then, get the second node's network information.

(lasp2@localhost)1> partisan_peer_service_manager:myself().
#{name => lasp2@localhost, listen_addrs => [#{ip => {127,0,0,1}, port => 56699}]}

Then, join the first node to the second node.

(lasp1@localhost)2> lasp_peer_service:join(#{name => lasp2@localhost, listen_addrs => [#{ip => {127,0,0,1}, port => 56699}]}).
