### Regarding the services
|
||||
|
||||
By default, it is not yet possible to combine TCP and UDP ports on a service with `type: LoadBalancer`. This can be solved in a number of ways:
|
||||
|
||||
1. Create a separate service containing the UDP ports. This could be done by disabling the UDP ports under `service.main.ports` and adding the following in your `values.yaml`:
|
||||
|
||||
```yaml
|
||||
service:
|
||||
udp:
|
||||
enabled: true
|
||||
type: LoadBalancer
|
||||
# <your other service configuration>
|
||||
ports:
|
||||
voice:
|
||||
enabled: true
|
||||
port: 9987
|
||||
protocol: UDP
|
||||
```
|
||||
|
||||
2. Since Kubernetes 1.20 there is a feature gate that can be enabled to allow TCP and UDP ports to coexist on Services with `type: Loadbalancer`.
|
||||
You will need to enable the `MixedProtocolLBService` feature gate in order to achieve this.
|
||||
|
||||
For more information about feature gates, please see [the docs](https://kubernetes.io/docs/reference/command-line-tools-reference/feature-gates/).
