安装Ingress Controller(如Nginx Ingress Controller)通常涉及几个步骤,这里以Kubernetes (k8s) v1.22.0和Nginx-Ingress为例,你需要先确保已部署了Kubernetes集群,并配置了kubectl访问权限。
1. **添加Nginx Ingress Repository到kubeconfig**:
使用`kubectl`添加官方Nginx Ingress仓库,这将允许从该源安装最新版本的控制器:
```
kubectl config set-context $(kubectl config current-context) --namespace=kube-system \
&& kubectl create secret generic ingress-nginx-certs \
--from-file=ca.crt=/etc/kubernetes/pki/ca.crt \
--from-file=ingress-class.yaml=/etc/nginx/ingress.class
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/v0.45.0/deploy/static/provider/cloud-generic/manifests/
```
2. **创建Ingress Class**:
创建一个名为`nginx-ingress-controller`的Ingress Class,告诉Kubernetes使用哪种控制器处理Ingress资源:
```yaml
cat <<EOF | kubectl apply -f -
apiVersion: networking.k8s.io/v1beta1
kind: IngressClass
metadata:
name: nginx
spec:
controller: "https://github.com/kubernetes/ingress-nginx.git?ref=v0.45.0"
EOF
```
3. **安装Nginx Ingress Controller**:
运行下面的命令来安装Nginx Ingress Controller,这个过程可能会需要一些时间:
```bash
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/v0.45.0/deploy/mandatory.yaml
kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/v0.45.0/deploy/provider/cloud-generic/manifests/service-account.yaml
```
4. **验证安装**:
确认Ingress Controller是否成功运行:
```shell
kubectl get pods -n ingress-nginx
```

2. 如何更新Ingress Controller到更高版本?
3. 如果遇到安装错误,如何排查和解决?
