I got a little web-service. On the back-end I got dockerized mongo and a few casual stuff like nodejs & nginx. Everything in separate container. And communicates via virtual network. So my web-service is working few months. And during this time my database has been dropped twice. But I haven't even committed any changes.
Mongo saves data into a volume. So all the data is ok after restarting containers. I checked out the logs, and saw this. But I've no idea why this is happening. Is it some hacker attack?
