As described in https://griddb.net/en/blog/run-a-griddb-server-in-docker-desktop/,

I did,

 docker pull griddbnet/griddb

and started docker image with,

docker run --hostname=localhost -d -t  griddbnet/griddb

And I have downloaded the Sample Java code to test connection.

However, always got connection errors,

I have tried this,

Properties props = new Properties();
props.setProperty("notificationMember", "127.0.0.1:31999");
props.setProperty("clusterName", "dockerGridDB");
props.setProperty("user", "admin"); 
props.setProperty("password", "admin");
GridStore store = GridStoreFactory.getInstance().getGridStore(props);

Collection<String, Person> col = store.putCollection("col01", Person.class);

Also tried,

Properties props = new Properties();
props.setProperty("notificationMember", "localhost:31999");
props.setProperty("clusterName", "dockerGridDB");
props.setProperty("user", "admin"); 
props.setProperty("password", "admin");
GridStore store = GridStoreFactory.getInstance().getGridStore(props);

Collection<String, Person> col = store.putCollection("col01", Person.class);

But got this error,
