# This script will help you running the different services needed
# in the open cloud stack :
#  - checks if directories containing the core services are present 
#  - allows you to build or not each service image
#  - launch the containerized service

#  TODO :
#  - Provide a list of all directories wich contain a dockerfile and choose which to build
#   - Parallelize building
#   - Flag building errors without stoping the other and flooding the stdout
#  - Provide a list of directories with a docker-compose and choose which to launch
