View Source gc_discover_epmd_all (gen_cluster v0.3.0)
Implementation of gc_discover that connects to all nodes found on the same epmd
as the one this node is connected to that also has the configured host. The
host defaults to the hostname of the current node's node name if no hosts key is
given in the options for this module.
Configuration examples
Using the application environment (these config list could also be passed in as
an argument to gen_cluster:start_link())
{gen_cluster, [{discover, {epmd_all, #{}}}]}
{gen_cluster, [{discover, {epmd_all, #{hosts => [rosa]}}}]}Summary

epmd. If hosts is not set in the configuration then the only host
checked for through epmd is the host of the current node's node name.
