notes on how i installed my beats on my home network. I should make an ansible module for that

install_beats.sh

#!/bin/bash 

VERSION=6.3.0

ROOT=${PWD}
BEATS_ROOT=/opt/beats
mkdir -p ${BEATS_ROOT} BEATS
cd BEATS


for beat in    filebeat packetbeat metricbeat auditbeat
  do
    if [ ! -d ${BEATS_ROOT}/${beat} ] ; then
     echo makeing ${BEATS_ROOT}/${beat}
     mkdir ${ROOT}/${beat}-${VERSION}
     cd ${ROOT}/${beat}-${VERSION}
     [ -f ${beat}-${VERSION}-linux-x86_64.tar.gz ] || wget  https://artifacts.elastic.co/downloads/beats/${beat}/${beat}-${VERSION}-linux-x86_64.tar.gz
     tar -xzvf ${beat}-${VERSION}-linux-x86_64.tar.gz
     mkdir -p ${BEATS_ROOT}/${beat}
     rsync -aP ${beat}-${VERSION}-linux-x86_64/  ${BEATS_ROOT}/${beat}/

cat <<EOF >> ${BEATS_ROOT}/${beat}/${beat}.yml
