這篇文章主要為大家介紹了kubernetes?Volume存儲卷configMap學習筆記，有需要的朋友可以借鑒參考下，希望能夠有所幫助，祝大家多多進步，早日升職加薪
前言
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(shù),args: []
- 將定義好的配置文件焙進鏡像之中;
- 通過環(huán)境變量向容器傳遞配置數(shù)據(jù):有個前提要求，應用得支持從環(huán)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(huán)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簡介
ConfigMap API資源用來保存key-value pair配置數(shù)據(jù)，這個數(shù)據(jù)可以在pods里使用，或者被用來為像controller一樣的系統(tǒng)組件存儲配置數(shù)據(jù)。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(tǒng)中的/etc目錄，專門用來存儲配置文件的目錄。
ConfigMap 通過env環(huán)境變量引用
通過環(huán)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(huán)境變量構建的列表。每個環(huán)項變量通常由name和value(或valueFron)字段構成
- name <string>:環(huán)境變量的名稱,必選字段;
- value <string>:環(huán)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(huán)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(huán)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(shù)據(jù)。
- 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(tǒng)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(tǒng)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
[root@k8s-master ~]# kubectl create configmap --help #查看示例
...
Examples:
# Create a new configmap named my-config based on folder bar
kubectl create configmap my-config --from-file=path/to/bar
# Create a new configmap named my-config with specified keys instead of file basenames on disk
kubectl create configmap my-config --from-file=key1=/path/to/bar/file1.txt --from-file=key2=/path/to/bar/file2.txt
# Create a new configmap named my-config with key1=config1 and key2=config2
kubectl create configmap my-config --from-literal=key1=config1 --from-literal=key2=config2
# Create a new configmap named my-config from the key=value pairs in the file
kubectl create configmap my-config --from-file=path/to/bar
# Create a new configmap named my-config from an env file
kubectl create configmap my-config --from-env-file=path/to/bar.env
Options:
--allow-missing-template-keys=true: If true, ignore any errors in templates when a field or map key is missing in

掛載configMap一部分資源時有兩種方法
1.掛載卷時通過items:參數(shù) 指定允許輸出到卷的鍵
2.在容器掛載卷時，指定掛載哪些卷
