Using VPCs with Harvester

This section contains an example of how Hedgehog Fabric can be used with Harvester or any hypervisor on the servers connected to Fabric. It assumes that you have already installed Fabric and have some servers running Harvester attached to it.

You need to define a Server object for each server running Harvester and a Connection object for each server connection to the switches.

You can have multiple VPCs created and attached to the Connections to the servers to make them available to the VMs in Harvester or any other hypervisor.

Configure Harvester

Add a Cluster Network

From the "Cluster Networks/Configs" side menu, create a new Cluster Network.

Harvester Cluster Network

Here is a cleaned-up version of what the CRD looks like:

apiVersion: network.harvesterhci.io/v1beta1
kind: ClusterNetwork
metadata:
  name: testnet

Add a Network Config

Click "Create Network Config". Add your connections and select the bonding type.

Harvester Network Config

The resulting CRD (cleaned up) looks like the following:

apiVersion: network.harvesterhci.io/v1beta1
kind: VlanConfig
metadata:
  name: testconfig
  labels:
    network.harvesterhci.io/clusternetwork: testnet
spec:
  clusterNetwork: testnet
  uplink:
    bondOptions:
      miimon: 100
      mode: 802.3ad
    linkAttributes:
      txQLen: -1
    nics:
      - enp5s0f0
      - enp3s0f1

Add VLAN based VM Networks

Browse over to "VM Networks" and add one network for each VLAN you want to support. Assign them to the cluster network.

Harvester VM Networks Harvester VM Network Details

Here is what the CRDs will look like for both VLANs:

apiVersion: k8s.cni.cncf.io/v1
kind: NetworkAttachmentDefinition
metadata:
  labels:
    network.harvesterhci.io/clusternetwork: testnet
    network.harvesterhci.io/ready: 'true'
    network.harvesterhci.io/type: L2VlanNetwork
    network.harvesterhci.io/vlan-id: '1001'
  name: testnet1001
  namespace: default
spec:
  config: >-
    {"cniVersion":"0.3.1","name":"testnet1001","type":"bridge","bridge":"testnet-br","promiscMode":true,"vlan":1001,"ipam":{}}

apiVersion: k8s.cni.cncf.io/v1
kind: NetworkAttachmentDefinition
metadata:
  name: testnet1000
  labels:
    network.harvesterhci.io/clusternetwork: testnet
    network.harvesterhci.io/ready: 'true'
    network.harvesterhci.io/type: L2VlanNetwork
    network.harvesterhci.io/vlan-id: '1000'
    #  key: string
  namespace: default
spec:
  config: >-
    {"cniVersion":"0.3.1","name":"testnet1000","type":"bridge","bridge":"testnet-br","promiscMode":true,"vlan":1000,"ipam":{}}

Using the VPCs

Now you can choose the new VM Networks when creating a VM in Harvester, and have them created as part of the VPC.
