I have followed the instructions at http://doc-en.tuleap.net/en/latest/developer-guide/quick-start/run-tuleap.html, but hitting http://tuleap_web_1.tuleap-aio-dev.docker/ gives "Server not found". The first two points under "3.4. Troubleshooting" seem OK, but the third one gives ";; connection timed out; no servers could be reached" on both the dig '*.docker', dig '*.tuleap-aio-dev.docker' and dig 'tuleap_web_1.tuleap-aio-dev.docker' commands.
Unfortunately, there are no follow up tips for when these commands fail. I will add that if I can solve the problem.
