Hi,  
 I want to run splunk-universalforwarder with non-root user. I created my own docker image and tried to run it.  
But when I run the docker image and it return error  as "sh: 1: cannot create /opt/container_artifact/splunk-container.state: Permission denied". 
 Details as below:  
- Dockerfile  
  FROM splunk/universalforwarder:latest
USER 9999
  
 
  Running command    
  docker build ./ -t uf_9999
