Configuration File:

By default, Eventool looks for configuration file in eventool/etc/hosts_conf.yaml. To change that, set environment variable export HOSTS_CONF=</path/to/file.suffix>

• Default values for all servers. Each value can be overridden for specific node
  • password
  • user
  • private_key (path)
• hosts:
  Each host is defined by addresses (ip/fqdn) and attributes:
  • alias: a list of aliases for the machine
  • override default values (password, user, etc...)
• roles:
  Each role can contain a list of aliases/addresses that will associate this role with the matching host
• fully_active_services:
  List of services that are Active/Active but don't use VIP. Unable to locate them since they are active on all HA nodes.
