xxx: xxx
5.下载镜像
docker pull registry.k8s.io/ingress-nginx/controller:v1.4.0
docker pull registry.k8s.io/ingress-nginx/kube-webhook-certgen:v20220916-gd32f8c343
docker pull registry.k8s.io/defaultbackend-amd64:1.5
#tag
docker tag registry.k8s.io/ingress-nginx/controller:v1.4.0 registry.cn-shanghai.aliyuncs.com/xxxx/prod:controller
docker tag registry.k8s.io/ingress-nginx/kube-webhook-certgen:v20220916-gd32f8c343 registry.cn-shanghai.aliyuncs.com/xxxx/prod:kube-webhook-certgen
docker tag registry.k8s.io/defaultbackend-amd64:1.5 registry.cn-shanghai.aliyuncs.com/xxxx/prod:defaultbackend-amd64
推到自己的镜像仓库xxxx
docker push registry.cn-shanghai.aliyuncs.com/xxxx/prod:controller
docker push registry.cn-shanghai.aliyuncs.com/xxxx/prod:kube-webhook-certgen
docker push registry.cn-shanghai.aliyuncs.com/xxxx/prod:defaultbackend-amd64

#如果没有仓库:

docker save -o controller.tar registry.k8s.io/ingress-nginx/controller:v1.4.0
docker save -o certgen.tar registry.k8s.io/ingress-nginx/kube-webhook-certgen:v20220916-gd32f8c343
docker save -o defaultbackend.tar registry.k8s.io/defaultbackend-amd64:1.5
#上传到k8s服务器

ctr -n=k8s.io image import controller.tar
ctr -n=k8s.io image import certgen.tar
ctr -n=k8s.io image import defaultbackend.tar
6.创建ns
kubectl create ns ingress-nginx
7.安装
helm install ingress-nginx -n ingress-nginx .

====================================================

8.安装成功出现一下内容:

NAME: ingress-nginx
LAST DEPLOYED: Fri Oct 28 13:40:16 2022
NAMESPACE: ingress-nginx
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
The ingress-nginx controller has been installed.
It may take a few minutes for the LoadBalancer IP to be available.
You can watch the status by running 'kubectl --namespace ingress-nginx get services -o wide -w ingress-nginx-controller'

An example Ingress that makes use of the controller:
  apiVersion: networking.k8s.io/v1
  kind: Ingress
  metadata:
    name: example
    namespace: foo
  spec:
    ingressClassName: nginx
    rules:
      - host: www.example.com
        http:
          paths:
            - pathType: Prefix
              backend:
                service:
                  name: exampleService
                  port:
                    number: 80
              path: /
    # This section is only required if TLS is to be enabled for the Ingress
    tls:
      - hosts:
        - www.example.com
        secretName: example-tls

If TLS is enabled for the Ingress, a Secret containing the certificate and key must also be provided:

  apiVersion: v1
  kind: Secret
  metadata:
    name: example-tls
    namespace: foo
  data:
    tls.crt: <base64 encoded cert>
    tls.key: <base64 encoded key>
  type: kubernetes.io/tls
