Facing issues in centos7 for AEM-author images

Hi All,

I am facing issues with AEM-author images that was suggested by following authors like this ggotti/aem-author.Icannot able to create the proper image
Second problem with file systems:
I want to convert the existing file system xfs to the ext4(extfs) that was suggested by the Docker for the production use.
can anyone suggested me the best docs to create Docker images for AEM-author,publisher and Dispatcher?(AEM is a webserver, in that these three are the modules).
