All services listen to 0.0.0.0 instead of 127.0.0.1 about kafka-stack-docker-compose

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

[simplesteph]

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

[amosbird]

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

[simplesteph]

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!
