Deploying VPP Agent Docker Images Using Kubernetes

This document describes how the development Docker image can be deployed on an one-node development Kubernetes cluster using kubeadm]1 with [Calico] networking on Linux.

The recipe described here has been tested with kubeadm version 1.6.3.

Init kubeadm master:

kubeadm init

cp /etc/kubernetes/admin.conf $HOME/
chown $(id -u):$(id -g) $HOME/admin.conf
export KUBECONFIG=$HOME/admin.conf

kubectl taint nodes --all node-role.kubernetes.io/master-

Enable Calico networking:

kubectl apply -f http://docs.projectcalico.org/v2.2/getting-started/kubernetes/installation/hosted/kubeadm/1.6/calico.yaml

Start ETCD on the host (a new ETCD instance on port 22379, since already running ETCD deployed by kubeadm does not accept remote connections):

sudo docker run -p 22379:2379 --name etcd --rm \
    quay.io/coreos/etcd:v3.0.16 /usr/local/bin/etcd \
    -advertise-client-urls http://0.0.0.0:2379 \
    -listen-client-urls http://0.0.0.0:2379

Start Kafka on the host:

sudo docker run -p 2181:2181 -p 9092:9092 --name kafka --rm \
 --env ADVERTISED_HOST=172.17.0.1 --env ADVERTISED_PORT=9092 spotify/kafka

Deploy VNF & vSwitch PODs:

kubectl apply -f vswitch-vpp.yaml
kubectl apply -f vnf-vpp.yaml

Verify the deployment:

kubectl get pods
kubectl describe pods

Write some config into ETCD (using etcd.conf that refers to the port 22379):

export ETCD_CONFIG=./etcd.conf
../../cmd/vpp-agent-ctl/topology.sh

Verify that the VPPs have been configured with some config:

kubectl describe pods | grep 'IP:'
IP:		192.168.243.216
IP:		192.168.243.217

telnet 192.168.243.216 5002
vpp# sh inter addr

memif0 (up):
  10.10.1.2/24
memif1 (up):
  166.111.8.2/24

vpp# sh inter addr
local0 (dn):
loop0 (up):
  6.0.0.100/24
loop1 (up):
  l2 bridge bd_id 1 bvi shg 0
  10.10.1.1/24

memif1 (up):
  l2 bridge bd_id 1 shg 0
memif2 (up):
  l2 bridge bd_id 1 shg 0
memif3 (up):
  l2 bridge bd_id 2 shg 0
vxlan_tunnel0 (up):
  l2 bridge bd_id 2 shg 0

Verify logs:

kubectl describe pods | grep 'Container ID:'
    Container ID:	docker://8511cbbbecff744a06fae94b861f8030bd7be52d2c2db0533b63ac151d36b13c
