KinD

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

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.

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

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

kubectl apply -f https://kube-vip.io/manifests/rbac.yaml

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.

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"

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

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