在Openshift Origin中写入文件时出错

Question

我正在为Openshift Origin部署一个基于camel的应用程序。 骆驼路由需要将一些pdf文件写入文件系统。 所以我创建了一个Persistent Volume Claim，然后为具有camel路由的Pod创建了存储。挂载引用了一个有效的目录，该目录可以从除root之外的其他用户写入。

PV已成功添加到pod中，因为我跑了

oc volume pod/sat-pdf-merger-7-64s9v

我得到了

pods/sat-pdf-merger-7-64s9v
  pvc/volume0 (allocated 100GiB) as volume-efwkb
    mounted at /recibos/pdf
  secret/default-token-r45zl as default-token-r45zl
    mounted at /var/run/secrets/kubernetes.io/serviceaccount

重要的是说同一个项目在Jboss Fuse 6.3上运行良好。因此抛出异常是因为某些Origin问题，而不是相关的camel或java代码问题。

当路由执行时，抛出以下异常：

修改

我在这里上传调试POD的结果。

我的Dockerfile

FROM 172.30.1.1:5000/myproject/fis-java-openshift:2.0
ENV JAVA_APP_DIR=/deployments
USER root   
RUN mkdir -p /home/jboss/recibos
RUN chmod -R 777 /home/jboss/recibos
COPY maven /deployments/
EXPOSE 8080 8778 9779

当调试pod时，我看到dockerfile中的mkdir实际上不起作用。所以我需要一些解决方法。
