关于k8s中subpath的使用详解

目录有两种情况：1.做为volumes使用时,subPath代表存储卷的子路径：2.作为configmap/secret使用时,subPath代表configmap/secret的子路径：

有两种情况：

1.做为volumes使用时,subPath代表存储卷的子路径：

apiVersion: v1 kind: Pod metadata: name: testpod0 spec: containers: – name: testc image: busybox command: [“/bin/sleep”,”10000″] volumeMounts: – name: data mountPath: /opt/data # 挂载的路径 subPath: data # volume的子路径 mountPath: /opt/model subPath: model volumes: – name: data persistentVolumeClaim: claimName: test-data

2.作为configmap/secret使用时,subPath代表configmap/secret的子路径：

apiVersion: v1 kind: ConfigMap metadata: name: config-test data: config.ini: “hello” config.conf: “nihao”

单独挂载一个key为文件

apiVersion: v1 kind: Pod metadata: name: testpod spec: containers: – name: testc image: busybox command: [“/bin/sleep”,”10000″] volumeMounts: – name: config-test mountPath: /etc/config.ini # 最终在容器中的文件名 subPath: config.ini #要挂载的confmap中的key的名称 volumes: – name: config-test configMap: name: config-test

挂载多个key为文件：

apiVersion: v1 kind: Pod metadata: name: testpod2 spec: containers: – name: testc image: busybox command: [“/bin/sleep”,”10000″] volumeMounts: – name: config-test mountPath: /etc/config.ini # 最终在容器中的文件名 subPath: config.ini #要挂载的confmap中的key的名称 mountPath: /etc/config.conf # 最终在容器中的文件名 subPath: config.conf #要挂载的confmap中的key的名称 volumes: – name: config-test configMap: name: config-test

多个container挂载不同的key：

apiVersion: v1 kind: Pod metadata: name: testpod1 spec: containers: – name: testc imagePullPolicy: Never image: busybox command: [“/bin/sleep”,”10000″] volumeMounts: – name: config-test mountPath: /etc/config/config.ini subPath: config.ini – name: testc1 imagePullPolicy: Never image: busybox command: [“/bin/sleep”,”10000″] volumeMounts: – name: config-test mountPath: /etc/config/config.conf subPath: config.conf volumes: – name: config-test configMap: name: config-test items: – key: config.ini path: config.ini – key: config.conf path: config.conf
