Have your AWS creds in $HOME/.aws . Then:
docker run -ti --rm -v "$PWD:/src" -v "$HOME/.ivy2":/root/.ivy2 -v "$HOME/.aws":/root/.aws -p 9000:9000 internal.hub.polyverse.io/bigbang-dashboard bash -c "cd /src ; sbt run"
Then open your browser at localhost:9000
docker build -t internal.hub.polyverse.io/bigbang-dashboard .
