Is there way to specify a custom NodePort port in a kubernetes service YAML definition? I need to be able to define the port explicitly in my configuration file.
You can set the type NodePort
in your Service
Deployment. Note that there is a Node Port Range
configured for your API server with the option --service-node-port-range
(by default 30000-32767
). You can also specify a port in that range specifically by setting the nodePort
attribute under the Port
object, or the system will chose a port in that range for you.
So a Service
example with specified NodePort
would look like this:
apiVersion: v1
kind: Service
metadata:
name: nginx
labels:
name: nginx
spec:
type: NodePort
ports:
- port: 80
nodePort: 30080
name: http
- port: 443
nodePort: 30443
name: https
selector:
name: nginx
For more information on NodePort, see this doc. For configuring API Server Node Port range please see this.
