Testing Steps

1. Copy config.yaml

$ sudo mkdir -p /etc/rancher/k3s && sudo cp config.yaml /etc/rancher/k3s

2. Install k3s

$ curl -sfL https://get.k3s.io | sudo INSTALL_K3S_COMMIT='79fd7469e5ce956d21d6ef48b1f3ce531ed92384' sh -s - server

3. Get Flannel Version using:

/var/lib/rancher/k3s/data/current/bin/flannel -v

4. Apply a test workload - clusterip.yaml
   Sample yaml:

apiVersion: v1
kind: Pod
metadata:
  name: clusterip-pod-demo
  labels:
    app1: clusterip-demo
    app.kubernetes.io/name: clusterip1
    app.kubernetes.io/kind: pod
    common: app
spec:
  initContainers:
  - name: init-myservice
    image: busybox:1.28
    command: ['sh', '-c', "sleep 5"]
  containers:
  - name: nginx-container
    image: nginx

Validation Results:

• k3s version used for validation:

k3s -v
k3s version v1.27.4+k3s-79fd7469 (79fd7469)
go version go1.20.6
