If I create a swarm and join 1 node to it. Create an overlay network. Create web service and DB as mentioned on the hands-on part. Will both the nodes be able to connect to the database? I tested it browsing of the site happens on both nodes but insert data is not working on the node where DB container is not there. So, I tried scaling up the DB service in order to make another container on the node where DB container was not there, now DB service container 1 each on both nodes still insert did not work. Wanted to know is the DB service is in the cluster. Please let me know if I want to make the service is in cluster how to do it?
