Kubernetes ingress nginx "not found" (les jackson tutorial)

I'm following the tutorial from Less Jackson about Kubernetes but I'm stuck around 04:40:00. I always get an 404 returned from my Ingress Nginx Controller. I followed everything he does, but I can't get it to work.

I also read that this could have something to do with IIS, so I stopped the default website which also runs on port 80.

The apps running in the containers are .NET Core.

Ingress-srv

        pathType: Prefix
        backend:
         service:
          name: platforms-clusterip-srv

         service:
          name: commands-clusterip-srv
          port:
           number: 80

I also added this to my hosts file: 127.0.0.1 acme.com

And I applied this from the nginx documentation:

kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.3.0/deploy/static/provider/cloud/deploy.yaml

kubectl get ingress kubectl get ingress

kubectl describe ing ingress-srv
kubectl describe ing ingress-srv

Dockerfile CommandService

FROM mcr.microsoft.com/dotnet/sdk:5.0 AS build-env
WORKDIR /app

COPY *.csproj ./
RUN dotnet restore

COPY . ./
RUN dotnet publish -c Release -o out

FROM mcr.microsoft.com/dotnet/aspnet:5.0
WORKDIR /app
COPY --from=build-env /app/out .
ENTRYPOINT [ "dotnet", "PlatformService.dll" ]

kubectl logs ingress-nginx-controller-6bf7bc7f94-v2jnp -n ingress-nginx LOGS INGRESS POD

Am I missing something?

Solution

  • I found my solution. There was a process running on port 80 with pid 4: 0.0.0.0:80. I could stop it using NET stop HTTP in an admin cmd.

    I noticed that running kubectl get services -n=ingress-nginx resulted a ingress-nginx-controll, which is fine, but with an external-ip . Running kubectl get ingress also didn't show an ADDRESS. Now they both show "localhost" as value for external-ip and ADDRESS.

    Reference: Port 80 is being used by SYSTEM (PID 4), what is that?
