- Introduced new IngressClass resource in Helm templates to define `easyhaproxy` as the default ingress class. - Updated Kubernetes examples to replace `easyhaproxy-ingress` with `easyhaproxy` as the ingress class name. - Enhanced processor logic to support both the new `spec.ingressClassName` field and the deprecated `kubernetes.io/ingress.class` annotation. - Revised documentation to reflect the changes and ensure alignment with Kubernetes recommendations.

# ==============================================================================
|
|
# EXAMPLE: Basic Kubernetes Ingress
|
|
# ==============================================================================
|
|
#
|
|
# WHAT THIS DEMONSTRATES:
|
|
# - Basic ingress configuration with EasyHAProxy
|
|
# - Multiple domains pointing to the same service
|
|
# - Complete deployment + service + ingress setup
|
|
# - HTTP ingress without TLS
|
|
#
|
|
# REQUIREMENTS (run these first):
|
|
# ```bash
|
|
# # 1. Ensure EasyHAProxy is installed in your cluster
|
|
# kubectl create namespace easyhaproxy
|
|
# kubectl apply -f https://raw.githubusercontent.com/byjg/docker-easy-haproxy/5.0.0/deploy/kubernetes/easyhaproxy-daemonset.yml
|
|
#
|
|
# # 2. Label the node where EasyHAProxy will run
|
|
# kubectl label nodes <node-name> "easyhaproxy/node=master"
|
|
#
|
|
# # 3. Add to /etc/hosts for local testing (idempotent)
|
|
# grep -q "example.org" /etc/hosts || echo "<node-ip> example.org www.example.org" | sudo tee -a /etc/hosts
|
|
# ```
|
|
#
|
|
# HOW TO START:
|
|
# ```bash
|
|
# kubectl apply -f service.yml
|
|
# ```
|
|
#
|
|
# HOW TO VERIFY IT'S WORKING:
|
|
# ```bash
|
|
# # Check resources are created
|
|
# kubectl get deployment,service,ingress container-example
|
|
#
|
|
# # Test via node IP
|
|
# curl -H "Host: example.org" http://<node-ip>:31080
|
|
# # Expected: 200 OK with "My Host Example"
|
|
#
|
|
# # Or use port-forward for testing
|
|
# kubectl port-forward -n easyhaproxy deployment/easyhaproxy 8080:80
|
|
# curl -H "Host: example.org" http://localhost:8080
|
|
# # Expected: 200 OK with "My Host Example"
|
|
#
|
|
# # Test second domain
|
|
# curl -H "Host: www.example.org" http://<node-ip>:31080
|
|
# # Expected: Same response
|
|
# ```
|
|
#
|
|
# CLEAN UP:
|
|
# ```bash
|
|
# kubectl delete -f service.yml
|
|
# ```
|
|
#
|
|
# ==============================================================================
