为内网LB版本的ingress创建一个独立的命名空间和docker-registry，(以仓库地址: uhub.service.ucloud.cn/ucloud_pts为例) 参考操作如下:
kubectl create ns ingress-inner
kubectl create secret docker-registry registry-secret-name
--namespace=ingress-inner
--docker-server=uhub.service.ucloud.cn/ucloud_pts
--docker-username='xxxxxxxxxxx'
--docker-password='xxxxxxxxxxx'获取 ingress-nginx chart包，修改为定制的ULB内网版本
helm repo add ingress https://kubernetes.github.io/ingress-nginx
helm repo update
helm fetch ingress/ingress-nginx
tar -xvpf ingress-nginx-3.33.0.tgz
编辑 ingress-nginx/Chart.yaml 修改以下字段
name: ingress-nginx-inner
修改 ingress-nginx/templates/controller-service.yaml 追加如下配置
metadata:
annotations:
service.beta.kubernetes.io/ucloud-load-balancer-type: inner
- 安装修改后的chart包
helm package ingress-nginx
cat > ingress-inner-value.yaml << EOF
