Make it easy for open liberty to run on k8s with read only file system

want to run the open liberty on the readonly file system on k8s (AKS) , we are facing issues in using the symbolic link..

Also wanted to know whats the real use of docker-server.sh which is there in the base image? is it really needed ?

is there a fully working sample of a Dockerfile which will run on k8s with R/O file system?
