fixes #7332

How to use

  1. Enable nginx-ingress
    minikube addons enable ingress
    
  2. Create a service and ingress
    kubectl create deployment web --image=gcr.io/google-samples/hello-app:1.0
    kubectl expose deployment web --port=8080
    kubectl apply -f https://k8s.io/examples/service/networking/example-ingress.yaml
    
  3. Add the following line to the bottom of the /etc/hosts file.
    127.0.0.1 hello-world.info
    
  4. Create tunnel
    sudo permission will be asked for it. It needs password
    minikube tunnel
    
  5. Verify that the Ingress controller is directing traffic:
    curl hello-world.info

Hi @zhan9san. Thanks for your PR.

I'm waiting for a kubernetes 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.

Hi,
Thanks for your attention. I add port 443 as well.

But you may know the certificate problem below

$ curl https://hello-world.info
curl: (60) SSL certificate problem: unable to get local issuer certificate
More details here: https://curl.haxx.se/docs/sslcerts.html

curl failed to verify the legitimacy of the server and therefore could not
establish a secure connection to it. To learn more about this situation and
how to fix it, please visit the web page mentioned above.
curl -k https://hello-world.info
Hello, world!
Version: 1.0.0
Hostname: web-79d88c97d6-xl5gv

Hi,
Thanks for taking my comment into consideration
The way I tested

# start new minikube with ingress addon
minikube start --nodes=2 --addons=ingress

# create workload
kubectl create deployment web --replicas=2 \
   --image=gcr.io/google-samples/hello-app:1.0

# create service
kubectl expose deployment web \
   --type=NodePort --port=8080

generate self-singed certificates for hello-world.info using this doc

# create tls secret
kubectl create secret tls hello-world-tls \
  --cert hello-world.info.pem \
  --key hello-world.info.key

# create ingress
kubectl create ingress hello-world-ingress \
  --rule=hello-world.info/=web:8080,tls=hello-world-tls

add 127.0.0.1 hello-world.info to /etc/hosts

start tunnel

minikube tunnel

check

curl https://hello-world.info/

and this worked

I'm glad to know it worked for you.
Besides, it tried your openssl-script and it worked great as well.

Hi @zhan9san, thank you so much for this PR! This fixes a long standing issue in our codebase and it's greatly appreciated. Could you change the ingress test at https://github.com/kubernetes/minikube/blob/master/test/integration/addons_test.go#L146 so that it doesn't skip the test for darwin docker driver anymore?

Currently, make integration will fail even when I use master branch.

I don't find integration test in Github workflow. Is it always running in local laptop?
After I enable ingress test on Darwin Docker driver, the integration tests for Ingress on MacOS pass as below.

As for the change in pkg/minikube/out/out.go, it fixes the unit test issue on MacOS which doesn't exist on Linux.

Error log is from this file, box-cli-maker, detect_unix.go and box-cli-maker, box.go

$ make test
...
open /proc/sys/kernel/osrelease: no such file or directory
...

The file, /proc/sys/kernel/osrelease doesn't exist on MacOS but Linux.

This issue results from the wrong value of box.Config.Color in

box.Config.Color = ""
and
isT := IsTerminal(w)

Here is an example to re-produce the issue, GoTerminal

The default value of box.Config.Color is RED, but it will be changed when we get a different value of IsTerminal.

That's why the Minikube binary file works well but integration/unit test fail.

Currently, make integration will fail even when I use master branch.

I don't find integration test in Github workflow. Is it always running in local laptop?

yeah, not of all of our integration tests pass currently, it's something we're actively working on. the integration tests don't run in github actions, they run in jenkins after one of our maintainers mark the PR as ok to test.

  2. make integration -e TEST_ARGS="-minikube-start-args=--driver=docker -test.run TestAddons/parallel/Ingress --profile=minikube" failed but it worked well before rebase.

    Fortunately, make integration -e TEST_ARGS="-minikube-start-args=--driver=docker -test.run TestAddons" works

Concerns:

  1. I run make test on master branch, and it failed as well. It seems the CI gateway doesn't block PR in which unit test failed.
  2. It seems the incoming code does not comply with quickly-iterating-on-a-single-test rule. Should someone update the document ?

Because I don't have much experience in Golang, please correct me if I say something wrong.

@zhan9san Are you required to add the IP at the bottom of the /etc/hosts file? or can you also skip that part and just curl 127.0.0.1?

I am sorry, and I can't follow you.

Does #13806 clear your concern?

Hello. I think issue is still present. I followed 13788 discussion.
Monterey 12.3.1 Intel i7
This was reproduced on docker driver too.

is not anyhow responding and is stuck until quit.

I was looking into 13806 and as that is a fresh PR wanted to confirm if that is patchable at that moment.

Also, I noticed this comment about alternate addresses.

I tried grepping cluster ip:

ps -ef | grep 10.105.66.48
  501 73767 69063   0  3:00AM ttys005    0:00.00 grep 10.105.66.48

Looks like ps is missing here for cluster ip, grep of cluster ip returns a record but without port. Is that a possible reason and if so what would be the fix?

I was able to access bitnami postgres by both other service and by dbeaver using minikube tunneling so I think that is an ingress issue.

Also addressing already mentioned comment, this neither does help:

kubectl -n kube-system rollout restart deployment coredns
deployment.apps/coredns restarted
curl hello-world.info

minikube start --driver=hyperkit

It seems your are not using Docker driver.

Hi @Findaa

Thanks for your detailed explanation.

Could you try to kill all other obsolete ssh process manually? and try again?

No need to recreate the service and ingress.

Based on the log above,

  1. Kill obsolete ssh process
sudo kill -9 34334 34653 60910 42128 42129
  1. Restart tunnel

Press Ctrl + c to stop the existing tunnel.

minikube tunnel --cleanup
  1. Verify service
$ curl hello-world.info
Hello, world!
Version: 1.0.0
Hostname: web-746c8679d4-9rt96

Amazing, that helped. Thank you a lot @zhan9san that is working solution.
For people following thread and having same issue, pid's are rather rapidly changing so verify with ps.
Would it be possible to know what caused the obselote ssh services? I suppose with each minikube restart this is going to happen over again, but at least solution is not complicated.

The root cause is that the 80 port is already bound which will result in unexpected behavior of minikube tunnel.

For your case, it's obsolete ssh process, maybe it's Nginx, Apache or other process for others.

Would it be possible to know what caused the obselote ssh services? I suppose with each minikube restart this is going to happen over again, but at least solution is not complicated.

I can't give you an exact answer. But I believe you know how to debug and fix it.
