Whales' names 🐋

Simplistic solution of why can't I reach my docker containers by name? problem. Continuously update hosts file (/etc/hosts) with docker container names and aliases and watch for changes.

Installation 🔨

$ npm install -g whales-names

Usage 📘

$ whales-names
Synchronizing docker container hostnames in hosts file.

Afterwards you are going to see a new section in the end of your /etc/hosts file:

...

# whales-names begin
172.21.88.220	dfbf5d96df3e node1 
172.21.94.104	79468a158d1e node2
172.21.89.244	0c9b251458f4 db
# whales-names end

You can end it with simple Ctrl+C. Errors, if any are going to be printed on the console.

Elevated privileges ⚠️

Due to file permissions of /etc/hosts file you need to use elevated privileges (run as Administrator, if you will) for running it.

Rae: You like whales?

Jesse: I like him.

Rae: Well, he doesn't like anybody, so stay away from him. You see, Willy's a case. A very special case.

Jesse: So? Who isn't?
