Unable to start drone:1 container

I am working with someone to setup Drone on a Linux CentOS 7.4 VM. We ran the docker run... command but we’re receiving an error. Why would this happen? Docker is running as root it seems and there is a /var/lib/drone/ directory which was created.

[root@hostname ~]# docker logs drone
{“error”:“unable to open database file”,“level”:“fatal”,“msg”:“main: cannot initialize server”,“time”:“2020-01-06T21:19:44Z”}

Fixed. We had to upgrade Docker version since we were on an old version distributed with CentOS 7.4.
