### Generic Dockerfile demonstrating good practices


### Imports

# Bad-ish, we do not need Ubuntu for this, nor do we want latest if we are using in a build system, predictable is better
FROM ubuntu:latest

# Better, using a small image since our app has no dependency on Ubuntu
FROM alpine:3.3

• With Docker 1.8.0 shipped new log-driver for GELF via UDP, this means that the logs from Docker Container(s) can be shipped directly to the ELK stack for further analysis.
• This tutorial will illustrate how to use the GELF log-driver with Docker engine.
• Step 1: Setup ELK Stack:
  • docker run -d --name es elasticsearch
  • docker run -d --name logstash --link es:elasticsearch logstash -v /tmp/logstash.conf:/config-dir/logstash.conf logstash logstash -f /config-dir/logstash.conf
  • Note the config for Logstash can be found at this link
  • docker run --link es:elasticsearch -d kibana
• Once the ELK stack is up now let's fire up our nginx container which ships its logs to ELK stack.

• LOGSTASH_ADDRESS=$(docker inspect --format '{{ .NetworkSettings.IPAddress }}' logstash)
• `docker run -d --net=host --log-driver=gelf --log-opt gelf-address=u
