Setup Papertrail for Elastic Beanstalk

01_papertrail.config

#  This is an example .ebextensions config for setting up Papertrail with AWS Elastic Beanstalk, with the ability
#  to access environment variables within the created config files. 
#  This is done by not directly creating /etc/log_files.yml, but by having a shell script create it for us:
#
#  /home/ec2-user/create_log_file.sh (created in the "files" block)
#   - Creates /etc/log_files.yml
#   - Can include environment variables from the host
#
#  The first container command (00_create_log_file_yml) will execute the script.
#
#  Most of this config was taken from https://gist.github.com/leonsodhi/8eb28e06b2c35c136bf8#file-01papertrail-config

Perfect, it's working fine. Thanks. (got difficulties with official script)
