Docker sometimes "falls asleep"?

I run my Nginx docker image via docker compose and everything (web) is ok. But sometimes randomly (after 10 hours uptime, 2 weeks… or 4 weeks…) is web down! … I connected on my server and run: “docker ps” and I see my image with uptime 1 second, 2 seconds… etc. and everything is ok again. I don’t know why docker doing that. … It’s happening on differenct cloud providers (coreos stable with 1.12.6 version).

I must enable docker service :blush: :dizzy_face:
systemctl enable docker
