一、问题描述
我们期望运行Ingress就必须给我们的集群创建Ingress controller
目前官方推荐的controller有：[目前支持和维护 AWS， GCE 和 nginx Ingress 控制器]
https://kubernetes.io/zh/docs/concepts/services-networking/ingress-controllers/
我们使用nginx控制器，其官网给出的配置方法如下：https://kubernetes.github.io/ingress-nginx/deploy/
# 不使用helm，使用yaml kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.1.1/deploy/static/provider/cloud/deploy.yaml
注意，不同的版本适应的k8s版本不同，详细见表格：（根据你的k8s版本选择支持的版本，替换上面的v1.1.1,我的是1.23）
| Ingress-NGINX version | k8s supported version | Alpine Version | Nginx Version |
|---|---|---|---|
| v1.1.1 | 1.23, 1.22, 1.21, 1.20, 1.19 | 3.14.2 | 1.19.9† |
| v1.1.0 | 1.22, 1.21, 1.20, 1.19 | 3.14.2 | 1.19.9† |
| v1.0.5 | 1.22, 1.21, 1.20, 1.19 | 3.14.2 | 1.19.9† |
| v1.0.4 | 1.22, 1.21, 1.20, 1.19 | 3.14.2 | 1.19.9† |
| v1.0.3 | 1.22, 1.21, 1.20, 1.19 | 3.14.2 | 1.19.9† |
| v1.0.2 | 1.22, 1.21, 1.20, 1.19 | 3.14.2 | 1.19.9† |
| v1.0.1 | 1.22, 1.21, 1.20, 1.19 | 3.14.2 | 1.19.9† |
| v1.0.0 | 1.22, 1.21, 1.20, 1.19 | 3.13.5 | 1.20.1 |
| v0.50.0 | 1.21, 1.20, 1.19 | 3.14.2 | 1.19.9† |
| v0.49.3 | 1.21, 1.20, 1.19 | 3.14.2 | 1.19.9† |
| v0.49.2 | 1.21, 1.20, 1.19 | 3.14.2 | 1.19.9† |
| v0.49.1 | 1.21, 1.20, 1.19 | 3.14.2 | 1.19.9† |
| v0.49.0 | 1.21, 1.20, 1.19 | 3.13.5 | 1.20.1 |
| v0.48.1 | 1.21, 1.20, 1.19 | 3.13.5 | 1.20.1 |
| v0.47.0 | 1.21, 1.20, 1.19 | 3.13.5 | 1.20.1 |
| v0.46.0 | 1.21, 1.20, 1.19 | 3.13.2 | 1.19.6 |
但是官方给出的yaml文件中拉取的镜像不在docker hub中，在k8s.gcr.io中，所以在国内我们拉取就会报错：ErrImagePull
$ k describe pod/ingress-nginx-admission-create-8zv9w ... ... Events: Type Reason Age From Message ---- ------ ---- ---- ------- Normal Scheduled 16m default-scheduler Successfully assigned ingress-nginx/ingress-nginx-admissio n-create-8zv9w to node2 Normal SandboxChanged 16m kubelet Pod sandbox changed, it will be killed and re-created.

相同问题的issue：https://github.com/kubernetes/ingress-nginx/issues/6335
issue中官方人员说没法上传到docker hub，可能也有自己的苦衷吧。。。
二、解决方法
解决方法很简单，用国内好心人搬运到docker hub上的仓库代替
好心人的项目地址：https://github.com/anjia0532/gcr.io_mirror，对应的docker hub地址：https://hub.docker.com/u/anjia0532
还可以手动发issue让其更新，以后gcr.io或k8s.gcr.io仓库的都可以在此更换
所以，v1.1.1版本的修改过的镜像的完整yaml文件如下：（我已经帮你找好了），如果你要使用其他版本ingress控制器，请在该docker hub上自己寻找替换，如果不是最新自己发issue拉取
