Docker container can't invoke

In our centos 7 machine, i can’t able to invoke an docker container, then did the ps -auwxx | grep migrations , don’t know in which service is running in root user .

I googled and found the link

Could you please let me know, what process is this .? Is this related to docker .?? How to resolve this error permanently .???

Your suggestions is highly appreciated.
