######Docker Build  and Versioning#########
## This section just decides what version of the docker image to build or run
## it decides this by the last time the Dockerfile or the requirements.txt were
## modified. Which ever was later is the version number we use
##
## Then if the image doesn't exist we create it

######Run me#########

#-v mounts a volume
#-rm removes the container when done
#-i -t interactive mode for bash
#bash at the end tells it to put us in a shell
docker run -v ~/.aws:/root/.aws -v ~/.ssh:/root/.ssh  -v $DIR/src:/root/src --rm   -i -t qbswebserver:$dcdate bash 


#TODO: once this is all built we will change from going to a shell to having an entry point script that just runs
