Question

I have docker installed on centos & system.
I am able to download docker images using docker pull command.
but when I run the container using docker run alpine, the server restarts.
this is happening every time.
I found this from /var/log/messages | grep docker

Any suggestions?

Answer 1

Found the answer to be storage driver problem.
the configuration of the server was not supporting the default overlay2 storage driver for docker. changing it to devicemapper fixed things.
