k8s configmap 挂载测试

cat application.properties
greeter.message="hello world"
volumeMounts:

• mountPath: /tmp/test/application.properties
  name: application-config
  subPath: application.properties
  readOnly: true

volumes:

• name: application-config
  configMap:
  name: spring-app-config
  defaultMode: 420
  items:
  • key: application.properties
    path: application.properties

将 ConfigMap 数据添加到卷中的特定路径
使用 path 字段为特定的 ConfigMap 项目指定预期的文件路径。 在这里，ConfigMap 中键 SPECIAL_LEVEL 的内容将挂载在 config-volume 卷中 /etc/config/keys 文件中。
