Port Range Mapping

Added in v0.56.0

We can use Go template’s range syntax combined with the built-in parseNumberRangePair function to implement port range mapping.

In the example below, after the application runs, 8 proxies will be created, named test-6000, test-6001 ... test-6007, which will map remote ports to local ports respectively.

{{- range $_, $v := parseNumberRangePair "6000-6006,6007" "6000-6006,6007" }}
[[proxies]]
name = "tcp-{{ $v.First }}"
type = "tcp"
localPort = {{ $v.First }}
remotePort = {{ $v.Second }}
{{- end }}
