Currently using RancherOS

[root@rancher-07 docker]# ros --version  
version v1.5.5 from os image rancher/os:v1.5.5  
[root@rancher-07 docker]# uname -a  
Linux rancher-07 4.14.138-rancher #1 SMP Sat Aug 10 11:25:46 UTC 2019 x86\_64 GNU/Linux

I need to understand how to set/modify ulimits for the system-dockerd process. Currently I am able to set/modify ulimits for the dockerd process by modifying the /etc/docker/system-docker.json file:

Example: Increased soft:hard max processes limit NPROC:

[root@rancher-07 docker]# pwd  
/etc/docker  
[root@rancher-07 docker]# ls  
key.json system-docker.json  
[root@rancher-07 docker]# more system-docker.json  
{  
“default-ulimits”: {  
“nproc”: {  
“Name”: “NPROC”,  
“Soft”: 512000,  
“Hard”: 512000  
}  
}  
}

After reboot I see the dockerd process has the changed NPROC but I was expecting this to also change the system-dockerd process ulimit as well.

What / Where do I need to make changes that effect the ulimit of the system-dockerd process?

Thanks in advance.
