build setup:

- install docker-compose: sudo apt install docker-compose
- create ~/.netrc file:

machine code.rdkcentral.com
	login username_from_rdk
	password password_from_rdk

- edit Dockerfile -> replace username and email for the git config lines
- sudo docker build .
- copy the resulting image hash
- replace the image hash in docker-compose.yml's image property (TODO: give the docker image a name and refer to that instead)
