#Web Developments script for pushing a docker container image to azures registry container. Ideally it's better to have a pipeline configured on azure for better development. We did'nt have the time to implement this with different libraries and codecs for the sepereate teams.

#Run this script locally to push uptowards registry.

#CONTAINER - azure registry container
#BRAINBEATS_VERSIONS - get repository tag image versions
#CURRENT_BRANCH - get current branch location from the current directory
#PRODUCTION_BRANCH - branch that pushes towards production
#Note make sure files are currently commited.
