In the upcoming lecture, we will be editing our hosts file so that we can access posts.com/posts in our browser. If you are unable to access the application you may have something already running on port 80, which is the default port for the ingress.

You'll need to identify what is using this port and shut it down. Some students have even had applications from other courses or personal projects still running. For Windows Pro users, both SQL Server Reporting Services (MSSQLSERVER) and the World Wide Web Publishing Service / IIS Server have been the most common services causing a conflict.

To determine what might be using this port, run:

macOS / Linux

sudo lsof -i tcp:80

Windows:

netstat -aon | findstr :80

Minikube users on Windows and macOS should make sure that they aren't using the docker driver which is not compatible with an ingress as noted here:
