Dear all,
I've read the documentation about ingress, and ingress controller
(https://kubernetes.io/docs/concepts/services-networking/ingress/,
https://github.com/kubernetes/ingress/tree/master/controllers). There is a
statement that says: "An Ingress Controller is a daemon, deployed as a
Kubernetes Pod". My question is how the traffic for our application is routed
to the ingress controller Pod?
For example: an organization has an internal k8s cluster, and wants to use the
nginx ingress controller. When the controller is deployed as a Pod it will
still run on the internal cluster. Then we create the ingress resource with a
rule like this:
- host: www.my-org-name.org
http:
paths:
- backend:
serviceName: webapp
servicePort: 12345
where the name www.my-org-name.org is resolved to one of the public IPs the
organization has. So how do the traffic coming from outside will reach the
ingress controller?
