debugging clear containers

#Debug with your own rootfs: Easy setup available to build your own kernel, rootfs and image available at:

$ git clone https://github.com/clearcontainers/osbuilder.git

##Connect to mini-OS: To aid in debug of the mini-os itself, you can create a debug console service and add it to the rootfs. Directions for this can be found at : https://github.com/jcvenegas/cc-oci-runtime/commit/3334a2bc7c915e

Make necessary changes in vm.json/hypervisor.args to move from pc-lite to pc:

description of memory holding with qemu and pc machine type

Reproducing Memory issues with PC and OVS/DPDK

setup OVS

This assumes you already have OVS and DPDK installed on your system

sudo mkdir -p /var/run/openvswitch
sudo killall ovsdb-server ovs-vswitchd
rm -f /var/run/openvswitch/vhost-user*
sudo rm -f /etc/openvswitch/conf.db

export DB_SOCK=/var/run/openvswitch/db.sock

Clear Containers, DPDK and OVS

Get the necessary sources

  • For plugin: go get github.com/clearcontainers/ovsdpdk
  • For ovs-dpdk enabled CC runtime: go get github.com/01org/cc-oci-runtime --> detail out getting the branch

Build the runtime

Will likely need a number of packages. For fedora 25, for example, run:

sudo dnf install \
glib2-devel-2.50.3-1.fc25.x86_64 \

SRIO-V with Docker CNM plugin

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 and Openshift

Running Openshift on top of Clear Containers 3.0

Overview

This documents how to get Openshift 3.6 on top of Kubernetes running with Clear Containers. An ansible playbook is used to provision a Fedora server 25 machine. Clear Containers is then installed and a basic test of deploying Clear Container and runc based pods is detailed.

Openshift

OpenShift is a public cloud application development and hosting platform which builds on top of the orchestration provided by Kubernetes.

Basic VPP setup for vhost-user and VMs

Basic VPP Setup for vhost-user interfaces and VMs

There are many examples of using VPP with tap interfaces/namespaces. After reviewing these, and details at https://wiki.fd.io/view/VPP/Tutorial_Routing_and_Switching, we came up with the following setup for testing inter-VM connectivity using VPP's vhost-user.

First time setup

Grab VPP packages, per directions from FD.io at https://wiki.fd.io/view/VPP/Installing_VPP_binaries_from_packages

$ sudo rm /etc/apt/sources.list.d/99fd.io.list
$ echo "deb [trusted=yes] https://nexus.fd.io/content/repositories/fd.io.ubuntu.xenial.main/ ./" | sudo tee -a /etc/apt/sources.list.d/99fd.io.list
