I have installed and run the docker container environment. No problems. Started and stopped several times. No problems. Stepped through setup of creating your own store from the Luma example. No problems. Tried launching the container and store today and I'm prompted for a magento2 password, which I do not know. It appears to be looking for the dB password which I am unable to figure out. I've tried removing all devbox directories and reinstalling and get the same prompt. How can I cleanly remove all components and get a fresh install?
