這篇文章主要介紹了kubernetes Volume存儲卷configMap怎么使用的相關知識，內容詳細易懂，操作簡單快捷，具有一定借鑒價值，相信大家閱讀完這篇kubernetes Volume存儲卷configMap怎么使用文章都會有所收獲，下面我們一起來看看吧。
核心資源類型存儲卷，PV、PVC、SC、CSI(Longhorn)
特殊類型的插件:ConfigMap、Secret、downwardAPI
如何為容器化應用提供配置信息:
啟動容器時,直接向應用程序傳遞參數,args: []
將定義好的配置文件焙進鏡像之中;
通過環境變量向容器傳遞配置數據:有個前提要求，應用得支持從環境變量加載配置信息;
制作鏡像時，使用entrypoint腳本來預處理變量，常見的做法就是使用非交互式編輯工具，將環境變量的值替換到應用的配置文件中;
基于存儲卷向容器傳遞配置文件;
運行中的改變,需要由應用程序重載;
ConfigMap API資源用來保存key-value pair配置數據，這個數據可以在pods里使用，或者被用來為像controller一樣的系統組件存儲配置數據。雖然ConfigMap跟Secrets類似，但是ConfigMap更方便的處理不含敏感信息的字符串。 注意：ConfigMaps不是屬性配置文件的替代品。ConfigMaps只是作為多個properties文件的引用。你可以把它理解為Linux系統中的/etc目錄，專門用來存儲配置文件的目錄。
通過環境變量的配置容器化應用時，需要在容器配置段中嵌套使用env字段，它的值是一個由環境變量構建的列表。每個環項變量通常由name和value(或valueFron)字段構成
name <string>:環境變量的名稱,必選字段;
value <string>:環境變量的值，通過 $(VAR_NAME)引用，逃逸格式為“$$(VAR_NAME)" 默認值為空;
valueFrom <object> ∶環境變量值的引用源，例如當前Pod資源的名稱、名稱空間、標簽等，不能與非空值的value字段同時使用，即環境變量的值要么源于value字段，要么源于valuFron字段，二者不可同時提供數據。
valueFron: 字段可引用的值有多種來源，包括當前Pod資源的屬性值，容器相關的系統資源配置、ConfigMap對象中的key以及Secret對象中的Key，它們分別要使用不同的嵌套字段進行定義。
fieldRef <bject>:當前Pod資源的指定字段，目前支持使用的字段包括metadata.mime、metadata.namespce、 metadata.labels、metadeta.annotations、spesc.nodeName、spec.serviceAccountName、status.hostIP和status.podIP等;
configMapKeyRef <Object>: ConfigMap對象中的特定Key;
secretKeyRef<object>: Secret對象中的特定Key;
resourceFieldRef <object>: 當前容器的特定系統資源的最小值(配額）或最大值《限額)，目前支持的引用包括 limits.cpu. limits.memory、limits.ephemeral-storage. requests.cpu、reuests.memory和requests.ephemeral-storage
