mkdir: cannot create directory '/var/lib/rabbitmq/mnesia': Permission denied - docker

Question

When I use dockerfile to build a rabbitmq image, it runs well with docker and kubernetes. but when I add pvc on it, container shows ' Crash loop back off'.
and the error is :
The following plugins have been configured:
rabbitmq_management
rabbitmq_management_agent
rabbitmq_web_dispatch
Applying plugin configuration to rabbit#rongqiyun-dev-base-qqqqqqqq-0...
The following plugins have been enabled:
rabbitmq_management
rabbitmq_management_agent
rabbitmq_web_dispatch
set 3 plugins.
Offline change; changes will take effect at broker restart.
mkdir: cannot create directory '/var/lib/rabbitmq/mnesia': Permission denied
Failed to create directory: /var/lib/rabbitmq/mnesia
Here is my dockerfile

RUN useradd -g rabbitmq rabbitmq

Before I add rabbitmq-persistent-storage, it can start normally.
