1、新建ConfigMap

apiVersion: v1
kind: ConfigMap
metadata:
  name: test-conf
  namespace: default
  labels:
    name: test-conf
data:
  test.properties: |
    db.url=jdbc:oracle:thin:@172.16.10.178:1521:orcl
    db.user=sz_res
    db.passwd=sz_res
  test2.properties: |
    xxxxxxxxxxxxxxxxxxxxxxxxxxxx

2、新建deployment

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: test-app
  namespace: default
spec:
  replicas: 1
  template:
    metadata:
      labels:
        app: test-app
    spec:
      containers:
        - name: test-container
          image: test/tomcat:v1
          imagePullPolicy: Always
          volumeMounts:
            - name: test
              mountPath: /usr/local/tomcat/webapps/test/WEB-INF/classes/test.properties
              subPath: path/to/test.properties
            - name: test2
              mountPath: /usr/local/tomcat/webapps/test/WEB-INF/classes/test2.properties
              subPath: path/to/test2.properties
      volumes:
        - name: test
          configMap:
            name: test-conf
            defaultMode: 0777
            items:
            - key: test.properties
              path: path/to/test.properties
        - name: test2
          configMap:
            name: test-conf
            items:
            - key: test2.properties
              path: path/to/test2.properties

挂载容器内部的文件的权限。（必须是介于0和0777（八进制）之间的数字，包括两者在内）

其实我没搞懂path/to/的意思
不过照着搬，的确好用，那就当作固定用法吧，
