Can you do: "git describe" in your fuego-core directory, and tell me what
it says?

This is a serious problem. I think it's likely that there's some runaway logging
going on inside the container. It would be good to isolate this and see what's
going on. It is possible some recent Docker changes have introduced a
new program that logs more than it should.
Here are some questions and some advice for finding the problem.
If you exit the container and restart it, does the size reset?
Do any files outside the container get bigger (e.g. in fuego-ro or fuego-rw
on your host system)?
Please try to find the file inside the container that is getting big.
First look at logging, and if it's not something obvious in there, then
look other places.
Inside the container, do:
$ cd /var/log
$ du -shx * | sort -h
You can use the 'du | sort' sequence in various directories to try to track
down where the size is accumulating. Since your container is at 45G, this will take
a long time if you run it at the root of the container filesystem, but that's probably
the best place to start.

I'm using Ubuntu 16.04 LTS on my Fuego host, and the latest Fuego version,
and I haven't seen this. My guess is that some error is triggering some repeated
message to a log.
Once we identify the file or directory that is growing inside the container,
we should be able to pinpoint the issue.
