Local K3D (k3s) cluster base

k3d-setup.sh

#!/bin/bash
CLUSTER_NAME="k3s-default"

# Install k3d
k3d --version || wget -q -O - https://raw.githubusercontent.com/rancher/k3d/master/install.sh | bash

# verify it
k3d check-tools

# create a volume and cluster
docker volume create kube-volume

k3d create --name "${CLUSTER_NAME}" --workers 3 --volume kube-volume:/opt/local-path-provisioner --wait 0
KUBECONFIG=$(k3d get-kubeconfig --name "${CLUSTER_NAME}")

echo "Replacing 'default' with '$CLUSTER_NAME' in $KUBECONFIG ..."
sed -i "s/\bdefault\b/${CLUSTER_NAME}/" "${KUBECONFIG}"

kubectl cluster-info

kustomize build --enable_alpha_plugins environments/dev | kubectl apply -f -

For me kubectl only started working after exporting $KUBECONFIG with

export KUBECONFIG=$(k3d get-kubeconfig --name "${CLUSTER_NAME}")
