how can I allocate my service (type=NodePort) on nodePort: 80

[dani8art]

Is this a BUG REPORT or FEATURE REQUEST? (choose one):
Feature request

Minikube version (use minikube version): v0.12.2

Environment:

• OS : windows
• VM Driver : virtualbox
• Docker version (e.g. docker -v): Docker version 1.11.1, build 5604cbe
• Install tools:
• Others:

What happened:

When I create a service (type=NodePort) and I want to allocate it to port 80 or 27017, kubectl responds:

The Service "pets-service" is invalid. spec.ports[0].nodePort: Invalid value: 80: provided port is not in the valid range

I've seem the documentation and I think that you can change some parameters on minikube start with --extra-config and in other issues that I could see say that I must change the ServiceNodePortRange. I've tried to execute:

minikube start --extra-config=apiserver.GenericServerRunOptions.ServerRunOptions.ServiceNodePortRange=1-30000

but this doesn't work.

I kwon I can set nodePort to other port in the range 30000-31000, but this solution isn't good for me.

any hint?

What you expected to happen:

How to reproduce it (as minimally and precisely as possible):

Run minikube

minikube start

Create service

kubectl create -f pets-service.yaml

Anything else do we need to know:

My service file:

apiVersion: v1
kind: Service
metadata:
 name: pets-service
 labels:
   name: pets-service
spec:
 type: NodePort
 ports:
   - port: 80
     targetPort: 80
     nodePort: 80
     protocol: TCP
 selector:
   name: pets-service

Hey,

Looks like Port Range uses a custom type and parser. We have to add that to the extra-config parsing. I just sent #837 to do that, then you should be good to go :)

Thank you but the error persits:

I send you logs outputs for checking.

What is good string for it works?

@dani8art You'll need to make sure you're consulting the right version of the k8s type. This struct changed between 1.4 and 1.5. You can check to see what version your minikube is running with kubectl version and looking at the server version.

This is the name of the struct for kubernetes 1.4.6, looks like the path would be api.ServerRunOptions.ServiceNodePortRange

Hi,

I've downloaded the latest build version of minikube from:

https://storage.googleapis.com/minikube-builds/837/minikube-windows-amd64.exe

and I've executed:

minikube start --extra-config=apiserver.ServerRunOptions.ServiceNodePortRange=1-30000

I think is the build version with the changes that resolves this bug #836 and now the error is different it says:

I1122 23:26:25.916788    2846 localkube.go:116] Setting ServerRunOptions.ServiceNodePortRange to 1-30000 on apiserver.

have I downloaded the good version of minikube?

I'll try this out now.

Whoops, I figured out the issue. It was the last swap of imports. The types aren't the same:

utilnet "k8s.io/kubernetes/pkg/util/net"
vs.
utilnet "k8s.io/client-go/1.4/pkg/util/net"

[dani8art]

That good, now it is working!
Thank you so much!

[dlorenc]

Great! We'll try to get a release out this week.
