I am using mysql cluster docker from below example
I have created a management node, a server node and 2 data node on 4 different Ubuntu machines.
It is working fine.
Then I wanted to add extra data node.
So I added a node on management mysql configuration file i.e. /etc/mysql-cluster.cnf.
Then i tried to restart the management node by using below command from inside docker.
ndb_mgmd -f /etc/mysql-cluster.cnf --reload.
But this is not working.
Anybody having solution for this.
