Using a Docker CNM plugin to play with SRIO-V

This gist describes the setup necessary for testing SRIO-V based connectivity between two physical boxes which are each setup as described here, and directly connected via their respective SRIO-V enabled NICs.

Setup host system's packages

For this scenario, I'm setting up two Ubuntu 16.04 systems which have a SRIO-V enabled interface as well as a second port for accessing the SUT. To setup:

Clear Containers Hands On

For people in the meetup to try the Clear Containers hands on exercise on their own

Setup

You can try the hands on either in a VM using ciao-down or directly on your host system

Using ciao-down

First setup a clear containers virtual machine on Ubuntu/fedora using the instructions here

The netfilter hooks in the kernel and where they hook in the packet flow

The figure below calls out

• The netfilter hooks
• The order of table traversal

mcastelino

How docker swarm load balanced traffic flows (on a given host).

How the traffic that get to a host is outside the scope of this.

Create a simple service

docker service create --name testswarm --replicas 1 --publish 8080:80 nginx /bin/bash -c "hostname > /usr/share/nginx/html/hostname; nginx -g \"daemon off;\""

Experimental Docker Libnetwork DHCP Driver

The DHCP driver is intended for users to be able to integrate Docker IP address management with their existing IPAM strategies that use DHCP for dynamic address assignment. DHCP enables users to allocate addresses in an organized fashion that will prevent overlapping IP address assignment by associating a unique MAC address from the container eth0 Ethernet interface to an IP address as determined by the DHCP pools defined in the DHCP configuration.

This driver only provides the DHCP client functionality. It does not include a DHCP server. The default driver offers single-host IPAM or for distributed multi-host orchestrated IPAM see the libnetwork overlay driver.

Getting Started

• Download the driver compiled into Docker Engine - docker binary with libnetwork test dhcp client spam driver
