Translate your KrakenD config file into a dot graph
$ go install github.com/krakendio/krakend-config2dot/v2/cmd/krakend-config2dot@latest
If you have your $GOPATH/bin in your $PATH, this is how you can create the .dot representation of your config file:
$ krakend-config2dot -c /path/to/your/config/file.json
Just pipe the output into dot.
$ krakend-config2dot -c /path/to/your/config/file.json | dot -Tpng -o config.png
