ENABLE_SSL=1 Error binding to port: listen tcp 0.0.0.0:3030: bind: address already in use

[deanwang2018]

I'm using macbook and when I want to enable ssl, the following error was there:

wangdians-mbp:fast-data-dev-master wangdian$ docker run --rm --net=host -e ENABLE_SSL=1 landoop/fast-data-dev TLS enabled. Creating CA and key-cert pairs. Error binding to port: listen tcp 0.0.0.0:3030: bind: address already in use Could not successfully bind to port 3030. Maybe some other service in your system is using it? Please free the port and try again.

checked no 3030 port was there by issue : lsof -i:3030 checked no this process was there by issue : ps aux | grep 3030

how to fix this ? Besides, where to lookup current landoop config parameter ? such as, how do I know current value of : BROKER_SSL, SSL_EXTRA_HOSTS , etc ?
