How can I run the docker that install in unbuntu 18.04 container

For some reason , I need to install a docker in my local ubuntu18.04 docker container ( my computer system was Centos ).
the docker was installed successfully in ubuntu18.04 container, but I canโ€™t start it. :joy::joy::joy:
It report as follow:
root@1178e61f5455:/etc/init.d# service docker start
/etc/init.d/docker: 103: ulimit: error setting limit (Operation not permitted)
root@1178e61f5455:/etc/init.d# systemctl start docker
System has not been booted with systemd as init system (PID 1). Canโ€™t operate.

Is there anyway to start the docker in other way ???

Thanks for all your helps!!!
