Configuration

As Object storages require authentication and other custom parameters, this software provide a way to use several configuration.

File format

Drivers configuration are stored as a YAML file containing one or several profile. Blow an example of file:

---
exoscale-dk-2:
  driver: exoscale
  aws_access_key_id: MyKey
  aws_secret_access_key: MySecret
  endpoint_url: https://sos-ch-dk-2.exo.io

exoscale-vie-1:
  driver: exoscale
  aws_access_key_id: MyKey
  aws_secret_access_key: MySecret
  endpoint_url: https://sos-ch-vie-1.exo.io

This file provides two profiles for an Exoscale benchmark, on in DK-2 and the other one in CH-VIE-1.

File choice

The general behavior is the following:

1. Configuration specified by user via CLI or Python
2. If environment variable OSB_CONFIG_FILE is set
3. ~/.osb.yml
4. /etc/osb.yml

Only the first file is used.
