Deploying KIND

The documentation for KIND is fantastic and its quick start guide will have you up and running in no time.

Find Address Pool for kube-vip

We will need to find addresses that can be used by kube-vip:

1docker network inspect kind -f '{{ range $i, $a := .IPAM.Config }}{{ println .Subnet }}{{ end }}'

This will return a CIDR range such as 172.18.0.0/16 and from here we can select a range.

Deploy the kube-vip Cloud Controller

1kubectl apply -f https://raw.githubusercontent.com/kube-vip/kube-vip-cloud-provider/main/manifest/kube-vip-cloud-controller.yaml

Add our Address range

1kubectl create configmap --namespace kube-system kubevip --from-literal range-global=172.18.100.10-172.18.100.30

Install kube-vip

Get latest version

We can parse the GitHub API to find the latest version (or we can set this manually)

KVVERSION=$(curl -sL https://api.github.com/repos/kube-vip/kube-vip/releases | jq -r ".[0].name")

or manually:

export KVVERSION=vx.x.x

The easiest method to generate a manifest is using the container itself, below will create an alias for different container runtimes.

containerd

alias kube-vip="ctr image pull ghcr.io/kube-vip/kube-vip:$KVVERSION; ctr run --rm --net-host ghcr.io/kube-vip/kube-vip:$KVVERSION vip /kube-vip"

Docker

alias kube-vip="docker run --network host --rm ghcr.io/kube-vip/kube-vip:$KVVERSION"

Deploy kube-vip as a DaemonSet

1kube-vip manifest daemonset --services --inCluster --arp --interface eth0 | kubectl apply -f -

Test

1kubectl apply -f https://k8s.io/examples/application/deployment.yaml

1kubectl expose deployment nginx-deployment --port=80 --type=LoadBalancer --name=nginx

1kubectl get svc
