Build docker images with the help of the ox-installer scripts. 
NOTE: Review the configuration used in the respective folder: singlenode/config or cluster/config 

Easiest way to get a working image:
    $ ${0} 

    Per component options (can be combined):

    Installation types (not combineable):
        --singlenode    This will install and init an basic OX instance (db, mw, fe)
        --cluster       This will create several images for deploying some docker-compose cluster
    Configuration options:
        

Examples:
