400 Bad request after running: docker run -p 0.0.0.0:8080:80 -v /home/mememe/www/flat/data:/data proycon/flat

[fishfree]

I followed the official doc here, however, when I access http://myhost:8080, http://myhost:8080/flat, http://myhost:8080/flat/pub all are 400 Bad request errors. Below are logs in the terminal:

docker run -p 0.0.0.0:8080:80 -v /home/mememe/www/flat/data:/data proycon/flat

BTW: where can I find the superadmin's username and password when running docker?

Sorry, I hadn't noticed this issue before. I'm not actually sure what caused this. Can you set --env FLAT_DEBUG=1 and try if the problem still occurs with the latest version? (just released, docker image is updated too)

BTW: where can I find the superadmin's username and password when running docker?

It's documented in the installation guide (it's flat:flat)
