Network ConfigurationDGX-2 System User Guide 30By default, Docker uses the 172.17.0.0/16 subnet. Consult your network administratorto find out which IP addresses are used by your network. If your network does notconflict with the default Docker IP address range, then no changes are needed andyou can skip this section.However, if your network uses the addresses within this range for the DGX-2 System,you should change the default Docker network addresses.You can change the default Docker network addresses by either modifyingthe /etc/docker/daemon.json file or modifying the /etc/systemd/system/docker.service.d/docker-override.conf file. These instructions providean example of modifying the/etc/systemd/system/docker.service.d/docker-override.conf to override the default Docker network addresses.1. Open the docker-override.conf file for editing.$ sudo vi /etc/systemd/system/docker.service.d/docker-override.conf[Service]ExecStart=ExecStart=/usr/bin/dockerd -H fd:// -s overlay2LimitMEMLOCK=infinityLimitSTACK=671088642. Make the changes indicated in bold below, setting the correct bridge IP address andIP address ranges for your network. Consult your IT administrator for the correctaddresses.[Service]ExecStart=ExecStart=/usr/bin/dockerd -H fd:// -s overlay2 --bip=192.168.127.1/24--fixed-cidr=192.168.127.128/25LimitMEMLOCK=infinityLimitSTACK=67108864Save and close the /etc/systemd/system/docker.service.d/docker-override.conf file when done.3. Reload the systemctl daemon.$ sudo systemctl daemon-reload4. Restart Docker.$ sudo systemctl restart docker
