### Optionally let _kubectl_ choose the local port {#let-kubectl-choose-local-port}
If you don't need a specific local port, you can let `kubectl` choose and allocate
the local port and thus relieve you from having to manage local port conflicts, with
the slightly simpler syntax:
```shell
kubectl port-forward deployment/redis-master :6379
```
The `kubectl` tool finds a local port number that is not in use (avoiding low ports numbers,
because these might be used by other applications). The output is similar to:
```
Forwarding from 127.0.0.1:62162 -> 6379
Forwarding from [::1]:62162 -> 6379
```
