Puppet
傀儡沒有拉動希拉的價值
學習 Puppet 和 Hiera，我遇到了障礙。如果這很簡單，我提前道歉。在我的 GitLab 中為 PuppetClass es_strat 提供以下文件：
傷口.yaml

es_heap=hiera("es_strat::es_heap") es_instances=hiera("es_strat::es_instances") es_version=hiera("es_strat::es_version") java_version=hiera("es_strat::java_version")但是，當我在主機上執行 puppet（特別是：puppet agent -t –no-noop）時，我收到以下錯誤：
錯誤：無法從遠端伺服器檢索目錄：伺服器上的錯誤 500：伺服器錯誤：評估錯誤：評估資源語句時出錯，函式查找（）在節點上找不到名稱“es_strat::es_instances”的值
拔掉我的頭髮，因為它似乎應該能夠從 Hiera 那裡獲得價值。非常感謝任何/所有幫助。
好的，所以這個類隨著從 Puppet 3 到 Puppet 4 的更新而損壞。我們使用 GitLab 來控制我們的模組/類。有了它，我能夠通過以下設置使其 99% 正常執行：
