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摘自
