Change bookinfo gateway Port to 80 from 8080

[shweshi]

Please provide a description of this PR:
The sample bookinfo example doesn't work with the istio-ingressgateway and bookinfo gateway because of port mismatch.

istio-ingressgateway.yaml

  - name: http2
    nodePort: 31156
    port: 80
    protocol: TCP
    targetPort: 80

bookinfo.gateway

    port:
      name: http
      number: 8080
      protocol: HTTP

This will cause error when accessing locally. (mac+minikube)

curl http://localhost:80/productpage
curl: (56) Recv failure: Connection reset by peer

Changing to port 80 works as expected.
bookinfo.gateway

    port:
      name: http
      number: 80
      protocol: HTTP

curl -s "http://localhost:80/productpage" | grep -o "<title>.*</title>"
<title>Simple Bookstore App</title>

This is causing issues while testing out the sample bookinfo and the documentation doesn't provide anything to fix the issue.

Hi @shweshi. Thanks for your PR.

I'm waiting for a istio member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

If this PR doens't get merge or meanwhile for people facing this issue:

• Edit the bookinfo-gateway.yaml

kubectl edit gateway bookinfo-gateway -n bookinfo

• Change the port from 8080 to 80 and save.

The changes will be applied, try the curl again and it should work.

curl -s "http://localhost:80/productpage" | grep -o "<title>.*</title>"
<title>Simple Bookstore App</title>

I recall the targetPort of ingressgateway should be 8080, ingressgateway listen at 8080, and this example work as expected.

@zirain targetPort is 80 when we install ingress-gateway from helm chart.

istio/manifests/charts/gateway/values.yaml

Line 48 in f25b023

targetPort: 80

So either we need to make change in bookinfo gateway or in istio ingress gateway to have target port as 8080 to make the bookinfo apps works.

Changing this would reintroduce #45726 (comment). There is a mismatch in the configuration of the gateway depending on which chart is used (gateway vs gateways):

istio/manifests/charts/gateways/istio-ingress/values.yaml

Lines 19 to 22 in f25b023

	- port: 80
	targetPort: 8080
	name: http2
	protocol: TCP
