Simply use the `ip` of the host machine to connect the DB. – Saqib Ahmed Apr 29 '18 at 14:11
thanks for response guys, @SaqibAhmed so am I need tell docker compose if I want to connect host ip ? – Ottoh Hidayatullah Apr 29 '18 at 14:19
Nope. You don't need to do anything. In your flask app, simply hardcode the IP of your host machine (where mongoDB is running) and that's it. – Saqib Ahmed Apr 29 '18 at 14:42
Add the code in your question where you connected to DB in your app. @OttohHidayatullah – Saqib Ahmed Apr 29 '18 at 14:43
Does `10.0.75.1` has mongoDB running on it? Is this the IP of your docker host? – Saqib Ahmed Apr 29 '18 at 14:47
ok I try to rebuild images and run this take a little bit long time. can we skip a few step when we want rebuild our images? @SaqibAhmed – Ottoh Hidayatullah Apr 29 '18 at 14:48
What do you mean by steps? – Saqib Ahmed Apr 29 '18 at 14:49
yaa before you comment I'm using localhost. I check ipconfig and show me IP of dockerNAT, is that true? @SaqibAhmed – Ottoh Hidayatullah Apr 29 '18 at 14:49
