Configuration

This is about how to fill the configuration file for the service

The configuration file needed by the application need to be in yaml format.

The configuration file could be named as you want, by default if you don't specified the parameter --configFile is config.yaml This could be located in any place, but by default when service start this find the configuration file in the following location:

1. ./config.yaml Next to the service binary mq-to-db
2. /etc/mq-to-db/config.yaml Into the standard Linux configuration filesystem
3. $HOME/config.yaml Into the user home which is executing the service binary mq-to-db

NOTE: Remember that thanks to the parameter --configFile you can tell to the service which configuration file you want to use, for example:

1. mq-to-db --configFile '/tmp/myconfig.yaml'
2. mq-to-db --configFile './mq-to-db.yaml'

To read the config file we are using the golang package viper and pflag

config.yaml

The config file config-sample.yaml could be used as template
