[doc] add interactive docker cmd

[mrx23dot]

docker restart macless-haystack

works as suggested in readme. But how can I run the docker in foreground, to see server responses?

docker run -it macless-haystack docker run macless-haystack says

Unable to find image 'macless-haystack:latest' locally
docker: Error response from daemon: pull access denied for macless-haystack, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.

also docker ps seems to only list anisette docker

so not sure why one command finds macless-haystack and others don't.

[johnnyrun]

you are confusing docker commands.

BTW:

docker logs -f macless-haystack

for details

works great, thank you! Might worth adding to readme.

Might worth adding to readme.

You mean something like this old FAQ ;)
