Empty response from server

[cschram]

I've tried several times to run Nuxeo through the docker container, following the documentation laid out here, but each time I end up with no response from http://localhost:8080/nuxeo (ERR_NO_DATA in Chrome).

There are no errors in any of the logs, and when I run a curl on localhost:8080 inside the container the connection is refused, so it seems like there's nothing actually listening on 8080.

This is happening on OSX Mojave, with Docker Desktop CE 2.1.0.1 (Docker Engine 19.03.1).

For reference, here's the terminal output from setting up the container:

EDIT: On closer inspection, it seems the server may be crashing or just not starting up at all.

It turns out that starting the server with the -ti option for docker exec is what was causing the issue - the process was being killed when the command was finished.
