Hi @smedava2 Apologies for the delay. now it should work. updated the docker instruction with latest ubuntu image let me know if that helps

[smedava2]

Thank you!! Installation worked smoothly. I am using your hello-f1 service to test out the nginx plus gateway. I am able to access it through the 3000 port but when i try it out using nginx plus I am getting a 404 with no helpful information in the logs. I don't think I missed any steps I have followed the steps in the git as well as the Show Code Episode 1 video. Not sure how to debug this to understand where the problem is.

Thanks! ~Swetha

Hi Swetha, since you are running docker , within nginx plus it needs to know what is the hello-f1 service endpoint. While packaging the nginx config, you could specify the upstream endpoint for hello-f1 as your local machine ip address to make it work. Eventually update the instruction for the same

Thank you Rajesh
