Method: Beaker::Options::Parser#parse_hosts_options

Defined in:
lib/beaker/options/parser.rb

#parse_hosts_options ⇒ Hash

Parse hosts options from host files into a host options hash. Falls back to trying as a beaker-hostgenerator string if reading the hosts file doesn’t work

Returns:

  • (Hash) —

    Host options, containing all host-specific details

Raises:

  • (ArgumentError) —

    if a hosts file is generated, but it can’t be read by the HostsFileParser
