Default Not configured
Command Mode CONFIGURATION
Usage
Information
OS10 does not support sending DNS queries over a VLAN. DNS queries are sent out on all other
interfaces, including the Management port. You can separately configure both IPv4 and IPv6 domain
name servers. In a dual stack setup, the system sends both A (request for IPv4) and AAAA (request for
IPv6) record requests to a DNS server even if you only configure this command. The no version of this
command removes the IP name-server configuration.
Example
OS10(config)# ip name-server 10.1.1.5

Containers
Docker-CE allows you to download and install external packages and run them within OS10.
When you start a container, use the --net= option to connect it to a network. This network can access the Management and
front-end interfaces. If you do not want networking for your Docker containers, use none.
If you are in the sysadmin group, you can run Docker commands from the OS10 Linux Shell.
Docker-CE restrictions
● Docker-CE is supported on platforms with at least 16 GB of flash memory.
● Docker-CE is disabled by default on the system.
● By default, the dockers that you create have no visibility to the Layer 2 traffic arriving on the data ports.
● Dell EMC Networking recommends creating containers only with the network type as host or none.
● Do not create bridge networks using the docker network create command as this configuration can conflict with the
OS10 networking capability.
● Interfaces that are part of nondefault VRFs are not available for Docker-CE containers.
● Do not use multiple containers simultaneously as this may affect system performance.
