node --inspect not working

[navinSing]

• Node.js Version:
  v7.7.2
• OS:
  Linux mh 3.19.0-31-generic how to set the timezone for node.js app #36~14.04.1-Ubuntu SMP Thu Oct 8 10:21:08 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

Using

docker service create --name aserv -p 9229:9229 -p 4848:4849 -p 18081:8080 node:7.7.2-alpine node --inspect=127.0.0.1:4849 /src/start.js

// tried all combinations
--inspect
--inspect=127.0.0.1:9229
--inspect=127.0.0.1:4848
--inspect=127.0.0.1:4849

Chrome version : 55.0
// added the following in chrome
chrome://inspect/#devices

Target discovery settings (Remote Target)
192.168.1.100:9229
192.168.1.100:4848
192.168.1.100:4849
localhost:9229
localhost:4848

And Didn't worked.

What is the best way to do this.

1. If we are using docker swarm the remote IP may not be available
2. how does port tunneling work here
3. and new url hash like
   chrome-devtools://devtools/bundled/inspector.html?experiments=true&v8only=true&ws=10.255.0.11:9229/c90e8346-11d6-47cf-aca4-d2360769bdd7

Both IP : 10.255.0.11
and hash : c90e8346-11d6-47cf-aca4-d2360769bdd7
are changing.. which means that i have to check the application logs to get this :S weird.
Can't the hash be sent as a parameter to command line .. or some other way to avoid this hash

Earlier with --debug it was not.
how do i debug a service in a swarm

you need to use --inspect=0.0.0.0:9229 because Docker doesn't route 127.0.0.1 through. Note this (comment) though, since 7.7.4 there's a bug that makes this not work. Suggestions there would be welcome!
