As an alternative to the very famous ngrok I used to use efrecon/localtunnel docker image to expose my http server on the internet for testing purposes.

With linux I used to:

• start my local HTTP server (let’s say on port 8080)
• start a container running the efrecon/localtunnel image with --network host:

  docker run -it -d --name localtunnel --network host efrecon/localtunnel --port 8080
  

• fetch the provided URL:

  export LOCAL_TUNNEL_URL=$(docker logs localtunnel | cut -d ' ' -f 4)
  

• et voilà:

  curl $LOCAL_TUNNEL_URL/hello
  

Of course, with MacOs it’s not possible to use the --network=host flag but I’m not finding the correct way to perform the same.
I tried multiple combinations like:

docker run -it -d --name localtunnel -p 8443:8080 efrecon/localtunnel --port 8080
curl $LOCAL_TUNNEL_URL:8443/hello

docker run -it -d --name localtunnel -p 443:8080 efrecon/localtunnel --port 8080
curl $LOCAL_TUNNEL_URL/hello

docker run -it -d --name localtunnel -p 80:8080 efrecon/localtunnel --port 8080
curl $LOCAL_TUNNEL_URL/hello

docker run -it -d --name localtunnel -p 9090:8080 efrecon/localtunnel --port 8080
curl $LOCAL_TUNNEL_URL:9090/hello

but none of them gave me results, only a dangling request waiting indefinitely to be achieved.
Any idea?
