概述

  k8s版本 1.27.x ingress-nginx 1.9.1 版本，在本文中介绍如何在 centos 7 中离线安装，并以 tomacat 作为测试进行实践。

相关连接

实践

镜像

  k8s我们需要离线镜像安装包，有能力的同学，可以自己拉取，可以直接使用上述资源，下载之后，按下面命令操作。docker相关知识快速补充

docker tag registry.cn-hangzhou.aliyuncs.com/google_containers/nginx-ingress-controller:v1.9.1 harbor.easzlab.io.local:8443/library/nginx-ingress-controller:v1.9.1
docker tag registry.cn-hangzhou.aliyuncs.com/google_containers/kube-webhook-certgen:v20230407 harbor.easzlab.io.local:8443/library/kube-webhook-certgen:v20230407
docker push  harbor.easzlab.io.local:8443/library/kube-webhook-certgen:v20230407
docker push  harbor.easzlab.io.local:8443/library/nginx-ingress-controller:v1.9.1
