I'm porting my dockerized app to kubernetes and I'm facing an issue creating a load balancer with aks:
The Service "lbalance" is invalid: spec.ports[0].nodePort: Invalid value: 80: provided port is not in the valid range.
The range of valid ports is 30000-32767
the configuration is pretty straightforward
apiVersion: v1
kind: Service
metadata:
name: lbalance
spec:
selector:
app: lbalance
ports:
- protocol: TCP
port: 80
targetPort: 80
nodePort: 80
name: http
- protocol: TCP
port: 443
targetPort: 443
nodePort: 443
name: https
type: LoadBalancerBehind that sits an haproxy with ssl termination toward the other services exposed within the cluster
In my testing environment I had a property to control which port to open ( --service-node-port-range ) but I cannot find that property neither on the portal page nor on the Azure documentation.
Is there a way to have a service on default ports or a recommended way to connect back to that Endpoint ports?
you need to remove the nodePort declaration from your yaml and it will get allocated by kubernetes from the pool mentioned in the error text (the only one you can use).
apiVersion: v1
kind: Service
metadata:
name: lbalance
spec:
selector:
app: lbalance
ports:
- protocol: TCP
port: 80
targetPort: 80
name: http
- protocol: TCP
port: 443
targetPort: 443
name: https
type: LoadBalancerthis way your service would be available on 80\443 and thing will work like they should
30000-32767 is the default nodeport range in kubernetes. you have defined as, nodePort: 443. it is not supported and hence the error was thrown.
follow the below steps
