docker container exits within ~15 seconds

Hi there.
After running the docker container using:
docker run -d -p 2700:2700 alphacep/kaldi-en:latest
with python8.0
it exits after about 15 seconds.
i don't see any errors in docker console (below)
i do see an error from command line, but i think b/c the docker container shuts down
any tips?

```
