### 开启ipvd功能的步骤:
| 步骤 | 操作 |
|------|------|
| 1 | 安装支持ipvd的CNI插件 |
| 2 | 配置kubelet参数 |
| 3 | 部署PV和PVC |
| 4 | 创建Deployment |
### 操作指南:
1. 安装支持ipvd的CNI插件:
```bash
# 下载支持ipvd的CNI插件
wget https://github.com/submariner-io/ipvlan-cni/blob/main/ipvlan https://github.com/containernetworking/plugins/releases/download/v0.8.4/cni-plugins-linux-amd64-v0.8.4.tgz
tar -xvf cni-plugins-linux-amd64-v0.8.4.tgz -C /opt/cni/bin/
# 配置CNI插件
echo '{"name": "ipvlan","type": "ipvlan", "master": "eth0","mode": "l3"}' > /etc/cni/net.d/10-ipvlan.conf
```
2. 配置kubelet参数:
```bash
# 编辑kubelet配置文件
vi /etc/default/kubelet
# 在KUBELET_EXTRA_ARGS中添加--node-ipvs-l3-enable=true
KUBELET_EXTRA_ARGS="--node-ipvs-l3-enable=true"
# 重启kubelet服务
systemctl restart kubelet
```
3. 部署PV和PVC:
```yaml
# pv.yaml
apiVersion: v1
kind: PersistentVolume
metadata:
name: pv-demo
spec:
capacity:
storage: 1Gi
accessModes:
- ReadWriteOnce
persistentVolumeReclaimPolicy: Retain
storageClassName: standard
mountOptions:
- l3
```
```yaml
# pvc.yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: pvc-demo
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 1Gi
storageClassName: standard
volumeMode: Filesystem
```
```bash
# 创建PV和PVC
kubectl apply -f pv.yaml
kubectl apply -f pvc.yaml
```
4. 创建Deployment:
```yaml
# deployment.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
name: nginx-deployment
spec:
replicas: 1
selector:
matchLabels:
app: nginx
template:
metadata:
labels:
app: nginx
spec:
containers:
- name: nginx
image: nginx
ports:
- containerPort: 80
volumeMounts:
- mountPath: "/usr/share/nginx/html"
name: html
volumes:
- name: html
persistentVolumeClaim:
claimName: pvc-demo
```
```bash
# 创建Deployment
kubectl apply -f deployment.yaml
```
