国内k8s的ingress-nginx镜像无法正常pull拉取问题怎么解决

这篇文章主要介绍“国内k8s的ingress-nginx镜像无法正常pull拉取问题怎么解决”，在日常操作中，相信很多人在国内k8s的ingress-nginx镜像无法正常pull拉取问题怎么解决问题上存在疑惑，小编查阅了各式资料，整理出简单好用的操作方法，希望对大家解答”国内k8s的ingress-nginx镜像无法正常pull拉取问题怎么解决”的疑惑有所帮助！接下来，请跟着小编一起来学习吧！

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]

我们使用nginx控制器，其官网给出的配置方法如下：

# 不使用helm，使用yamlkubectl 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）

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-admission-create-8zv9w to node2                                                                                                       Normal   SandboxChanged  16m                 kubelet            Pod sandbox changed, it will be killed and re-created.      Warning  Failed          14m (x6 over 16m)   kubelet            Error: ImagePullBackOff                                     Normal   Pulling         14m (x4 over 16m)   kubelet            Pulling image "k8s.gcr.io/ingress-nginx/kube-webhook-certgen:v1.1.1@sha256:64d8c73dca984af206adf9d6d7e46aa550362b1d7a01f3a0a91b20cc67868660"                                            Warning  Failed          14m (x4 over 16m)   kubelet            Failed to pull image "k8s.gcr.io/ingress-nginx/kube-webhook-certgen:v1.1.1@sha256:64d8c73dca984af206adf9d6d7e46aa550362b1d7a01f3a0a91b20cc67868660": rpc error: code = Unknown desc = Error response from daemon: Get "https://k8s.gcr.io/v2/": net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)  Warning  Failed          14m (x4 over 16m)   kubelet            Error: ErrImagePull  Normal   BackOff         77s (x58 over 16m)  kubelet            Back-off pulling image "k8s.gcr.io/ingress-nginx/kube-webhook-certgen:v1.1.1@sha256:64d8c73dca984af206adf9d6d7e46aa550362b1d7a01f3a0a91b20cc67868660"

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

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
