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.
● Do not run CPU intensive Docker containers.
Enable Docker-CE
● Use the following commands in the OS10 Linux Shell:
sudo systemctl enable docker
sudo systemctl start docker
NOTE: When you run the docker run command to create a container, you must use the --net=host parameter.
Install a Docker image
● To pull the latest Docker image from a Docker hub:
docker pull nginx
