Not able to expose port 80 on the host kubernetes ingress

Question

I’m trying to work ingress with kubernetes but it doesn’t work. I’m able to deploy everything successfully, but not able to expose port 80 on the host and hence I have no access.

I’m using this tutorial

Answer 1

Are you using flannel by any chance?

Yesss I'm using flannel

Answer 2

I was facing the same error.

The nginix ingress controller uses hostPort to expose ports 80 and 443 directly from the host. However, even I'm using Flannel as an overlay network with CNI, and hostPort is unavailable when CNI is used.

I could use nodePort, but then I may as well just use a regular service anyway. I'll be using a standard load balancer in front of my ingress hosts that's not part of the Kubernetes system and it should work just fine.
