Packages

November 2017: lucasbak Ryba does only support prometheus 2.0. If admisitrator want to use older version the commandline options should be changed (for example -config.file has become --config.file) in order for systemd to start correctly the process.

  options.version ?= '2.0.0-rc.2'
  options.source ?= "https://github.com/prometheus/prometheus/releases/download/v#{options.version}/prometheus-#{options.version}.linux-amd64.tar.gz"

configure by default two new label, one cluster and the other service Note: cluster name shoul not contain other character than ([a-zA-Z0-9-_]*)
