# Source: contiv-vpp/templates/vpp.yaml
# Contiv-VPP deployment YAML file. This deploys Contiv VPP networking on a Kuberntes cluster.
# The deployment consists of the following components:
#   - contiv-etcd - deployed on k8s master
#   - contiv-vswitch - deployed on each k8s node
#   - contiv-ksr - deployed on k8s master

#  Configuration
###########################################################

# This config map contains contiv-agent configuration. The most important part is the ipamConfig,
# which may be updated in case the default IPAM settings do not match your needs.
# nodeConfig may be used in case your nodes have more than 1 VPP interface. In that case, one
# of them needs to be marked as the main inter-node interface, and the rest of them can be
# configured with any IP addresses (the IPs cannot conflict with the main IPAM config).
