- 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.

# Kubernetes Static Manifests
|
|
|
|
⚠️ **IMPORTANT**: These files are **auto-generated** from Helm templates. Do not edit them directly!
|
|
|
|
## About These Files
|
|
|
|
This directory contains pre-rendered Kubernetes manifests for deploying EasyHAProxy without Helm. These are generated from the Helm chart at `../../helm/easyhaproxy/` and provide three deployment options:
|
|
|
|
| File | Type | Use Case |
|
|
|-----------------------------|------------------------|--------------------------------------------------------------|
|
|
| `easyhaproxy-daemonset.yml` | DaemonSet + hostPort | Direct host networking, best for bare-metal or simple setups |
|
|
| `easyhaproxy-nodeport.yml` | Deployment + NodePort | Exposes via NodePort (31080/31443/31936) |
|
|
| `easyhaproxy-clusterip.yml` | Deployment + ClusterIP | Internal cluster access only, use with external LoadBalancer |
|
|
|
|
## How to Use
|
|
|
|
Choose the manifest that fits your deployment scenario:
|
|
|
|
```bash
|
|
# Option 1: DaemonSet mode (hostPort)
|
|
kubectl apply -f easyhaproxy-daemonset.yml
|
|
|
|
# Option 2: NodePort mode
|
|
kubectl apply -f easyhaproxy-nodeport.yml
|
|
|
|
# Option 3: ClusterIP mode
|
|
kubectl apply -f easyhaproxy-clusterip.yml
|
|
```
|
|
|
|
For more details, see the [Kubernetes documentation](../../docs/kubernetes.md).
|
|
|
|
## Regenerating These Files
|
|
|
|
**When to regenerate:**
|
|
- After modifying Helm chart templates (`helm/easyhaproxy/templates/`)
|
|
- After updating default values (`helm/easyhaproxy/values.yaml`)
|
|
- After a new release to sync with latest Helm chart
|
|
|
|
**How to regenerate:**
|
|
|
|
```bash
|
|
# Navigate to helm directory
|
|
cd helm
|
|
|
|
# Generate DaemonSet manifest (hostPort mode)
|
|
helm template ingress ./easyhaproxy --namespace easyhaproxy \
|
|
--set service.create=false \
|
|
> ../deploy/kubernetes/easyhaproxy-daemonset.yml
|
|
|
|
# Generate NodePort manifest
|
|
helm template ingress ./easyhaproxy --namespace easyhaproxy \
|
|
--set service.create=true \
|
|
--set service.type=NodePort \
|
|
> ../deploy/kubernetes/easyhaproxy-nodeport.yml
|
|
|
|
# Generate ClusterIP manifest
|
|
helm template ingress ./easyhaproxy --namespace easyhaproxy \
|
|
--set service.create=true \
|
|
--set service.type=ClusterIP \
|
|
> ../deploy/kubernetes/easyhaproxy-clusterip.yml
|
|
```
|
|
|
|
**Verify regeneration:**
|
|
|
|
```bash
|
|
# Check IngressClass is present
|
|
grep "kind: IngressClass" ../deploy/kubernetes/easyhaproxy-*.yml
|
|
|
|
# Validate manifest syntax
|
|
kubectl apply --dry-run=client -f ../deploy/kubernetes/easyhaproxy-daemonset.yml
|
|
```
|
|
|
|
## What's Included
|
|
|
|
Each manifest contains:
|
|
- **ServiceAccount**: RBAC identity for EasyHAProxy
|
|
- **ClusterRole**: Permissions to read Ingress resources and Secrets
|
|
- **ClusterRoleBinding**: Binds the role to the service account
|
|
- **IngressClass**: Defines `easyhaproxy` as the ingress class
|
|
- **DaemonSet/Deployment**: The EasyHAProxy workload
|
|
- **Service** (NodePort/ClusterIP only): Network exposure
|
|
|
|
## Source of Truth
|
|
|
|
The Helm chart at `../../helm/easyhaproxy/` is the **source of truth**. All changes should be made there, then these static manifests regenerated.
|
|
|
|
**To modify these deployments:**
|
|
1. Edit Helm templates in `helm/easyhaproxy/templates/`
|
|
2. Update default values in `helm/easyhaproxy/values.yaml`
|
|
3. Regenerate static manifests using commands above
|
|
4. Commit both Helm changes and regenerated manifests |
