Why do I need kubernetes Ingress for custom domain?
I deployed my app using kubernetes and now Id like to add custom domain to the app. I am using this tutorial and it uses ingress to set the custom domain.
I noticed that the app load balancer has an ip. Why shouldn't I use that ip? What is the reason I need ingress?

If you want to expose your app, you could just as easily use a service of type NodePort instead of an Ingress. You could also use the type LoadBalancer. LoadBalancer is a superset of NodePort and assigns a fixed ip. With the type LoadBalancer you could assign a domain to this fixed IP. How to do this depends on where you have registered your domain.
To answer your questions:
- You do not need an Ingress you could use a
NodePortservice or
LoadBalanderservice. - To assign a domain to your app, you do not
need an Ingress, you could use aLoadBalancerservice - In any case,
you could just use the ip, but as already pointed out, a domain is
more convenient.
If you just want to try out your app, you could just use the IP. A domain can be assigned later.

Why not cname the load balancer ip in the DNS?
– Naor
Nov 22 '18 at 15:15
Which DNS do you mean?
– mbuechmann
Nov 22 '18 at 15:31
I have the IP of the load balancer, so I can config the DNS of the domain to transform to that IP (or is it A record? I am not familiar with DNS)
– Naor
Nov 22 '18 at 15:39
Yes, of course you can do that. You need to set the A-Record to the IP.
– mbuechmann
Nov 22 '18 at 15:48
So why do I need to use Ingress? Why it is better then A-Record for that ip?

Using domains over IPs has it's obvious advantages of not having to memorize 158.21.72.879 instead of mydomain.com.
Next, using mydomain.com, you can change your IP as many times as you like without having to change your calls to mydomain.com.
Ingress comes in different flavors, is highly configurable, allows for traffic redirection using kubernetes service names and some of them even have their own stats page so you can monitor your requests.
Furthermore, if you are using gcloud or the like, the LoadBalancer IP could change (unless confiugred otherwise), assigning you any available IP from your IP pool.
The real question is - why NOT use an Ingress?
