I created web applications(visual studio code - asp.net core) which ran successfully on docker and then I exposed these applications with the following commands in ubuntu terminal:
(1) kubectl expose deployment websa-node --name=websa-node --type=LoadBalancer --port=80
(2) kubectl expose deployment websc-node --name=websc-node --type=LoadBalancer --port=3030
(copied and pasted 0.0.0.0:3030 in chrome after running it in docker)
The results on chrome which I started the services for both of these applications are:
(1) http://192.168.99.100:30235
(2) http://192.168.99.100:32632
Neither ip addresses mentions the port I used to expose the applications with, how is that possible?
