gitlab runner error: No such image

if you run your own gitlab runner and you get the error message ERROR: Preparation failed: Error: No such image: mariadb:10.1 (executor_docker.go:175:0s) it can have multiple reasons.

sometimes the solution really can be very easy. in my case the error message was not really helpful but the soltuion was quickly to find. the server ran out of harddisk space, which can happen if you use lvm with extra small partitions like me.
