On docker I ran the command: "docker run --name elasticsearch-instance -p 9300:9300 -p 9200:9200 -d elasticsearch"

And then I tried to connect using the Java Driver to do a small test.

But it returns an error for refused connection:

NoNodeAvailableException[None of the configured nodes are available: [{#transport#-1}{ZMxWNaY-QPKf9YCkpnRRqw}{localhost}{127.0.0.1:9300}]  
]

at org.elasticsearch.action.ActionRequestBuilder.execute(ActionRequestBuilder.java:54)

I have tried some parameters such as  
-Des.network.host=0.0.0.0 and -Des.network.host=0.0.0.0 but without sucess.

p.s: I did the same test downloading and then run ES manually and the code works
