First of all if you’re using docker container ,you’re already using open distro. otherwise if you connect all your node
node1* master discovery.zen.ping.unicast.hosts: ["node1_ip", "node2_ip","node_3_ip"] (like this)
then when you change something in master node it’ll affect all node without changing anything.
for instance if you change elastic password in node1 (which is master node) after that you can use that password for all node’s and kibana…
