All services listen to 0.0.0.0 instead of 127.0.0.1 #26

Hi, I have /etc/hosts like this


127.0.0.1     kafka1
127.0.0.1     kafka2
127.0.0.1     kafka3
127.0.0.1     zoo1
127.0.0.1     zoo2
127.0.0.1     zoo3
...

However, docker-compose -f full-stack.yml up still starts all services listening to 0.0.0.0.

What's the problem? the entry in /etc/hosts are just here so that your computer solves kafka1 to localhost hence find the docker container

@simplesteph Oh, I thought the host list also acts as a config for restricting network accessibilities. Does that make sense?

simplesteph commented 6 years ago

no it doesn't restrict network capabilities, it just redirects DNS names to IPs:https://askubuntu.com/questions/183176/what-is-the-use-of-etc-hosts

Your service can be accessible from the outside if the firewall ports are opened. Remember the goal of this is to setup something on your local laptop, nothing more. Happy hacking!

Hmm, is there a way to run zk-single-kafka-single.yml without modifying /etc/hosts?
