Hi, Yuri, 

I tried Sapphire and get a 'Undefiend' error when connect to my IRIS. the URL I used is : "jdbc:IRIS://LOCALHOST:9091/USER". I am not sure it's okay, because from container system, I can ping LOCALHOST, but I don't think this is the docker Host server, my MAC os, and I can't ping MAC OS's any ip address from docker. Any suggestion? thank you
