Docker image can't connect to Ethereum node

[kdelwat]

When running the Docker image as specified in the README, I get the following error:

Error: CONNECTION ERROR: Couldn't connect to node http://localhost:8545.

I've run testrpc in another terminal, but it still isn't working. Not sure if I'm doing something wrong 😄
