Testing Environment Setup⚓

Local Kubernetes with k3d⚓

This guide shows how to set up a local testing environment using k3d. Other solutions like minikube, kind, or Talos can also be used.

Prerequisites⚓

k3d installed
kubectl configured
Docker running

Setup Steps⚓

1. Create Local Registry (Optional)⚓

k3d registry create registry.localhost --port 5000

2. Create Kubernetes Cluster⚓

Create a 3-node cluster with the following features:

Traefik ingress controller on port 18081
CSI storage on /mnt/k3d for data persistence
Private registry access configured

cat > ~/.k3d/k3d-cluster.yaml <<EOF
apiVersion: k3d.io/v1alpha5
kind: Simple
metadata:
  name: k3d
servers: 1
agents: 2
volumes:
  - volume: "/etc/ssl/certs/ca-certificates.crt:/etc/ssl/certs/ca-certificates.crt"
  - volume: /mnt/k3d:/var/lib/rancher/k3s/storage
    nodeFilters:
      - server:0
      - agent:*
ports:
  - port: 18081:80
    nodeFilters:
      - loadbalancer
registries:
  use:
    - k3d-registry.localhost:5000
EOF

k3d cluster create --config ~/.k3d/k3d-cluster.yaml

3. Verify Setup⚓

# Check cluster status
kubectl cluster-info

# Check nodes
kubectl get nodes

# Check ingress controller
kubectl get pods -n kube-system | grep traefik
