## To install Kibana
sudo docker pull sebp/elk:latest

## To run the link on your localhost just to test
docker run --link zentral_elastic_1:elasticsearch -p 127.0.0.1:5601:5601 --net zentral_default kibana

## After this, you should be able to access the Kibana dashboard from 127.0.0.1:5601

## Edit the base.json under conf/start/zentral/base.json
vi ./conf/start/zentral/base.json

//JSHint brought my attention to the fact that some PERLisms are just not cool in JS anymore...

//This is cool with JSHint:
console.time('if1'); 
for (var i = 0; i < 100000; i++) { 
  if(1) { //nice and safe, and don't even THINK of skipping those {}s, even though you don't need them either...
    console.log(1 + 1); 
  } 
} 
console.timeEnd('if1');
