本文主要介紹了解決國內(nèi)k8s的ingress-nginx鏡像無法正常pull拉取問題，文中通過示例代碼介紹的非常詳細(xì)，對大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價(jià)值，需要的朋友們下面隨著小編來一起學(xué)習(xí)學(xué)習(xí)吧

一、問題描述

我們期望運(yùn)行Ingress就必須給我們的集群創(chuàng)建Ingress controller

目前官方推薦的controller有：[目前支持和維護(hù) AWS， GCE 和 nginx Ingress 控制器]

https://kubernetes.io/zh/docs/concepts/services-networking/ingress-controllers/

我們使用nginx控制器，其官網(wǎng)給出的配置方法如下：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，不同的版本適應(yīng)的k8s版本不同，詳細(xì)見表格：（根據(jù)你的k8s版本選擇支持的版本，替換上面的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

但是官方給出的yaml文件中拉取的鏡像不在docker hub中，在k8s.gcr.io中，所以在國內(nèi)我們拉取就會(huì)報(bào)錯(cuò)：ErrImagePull

相同問題的issue：https://github.com/kubernetes/ingress-nginx/issues/6335

issue中官方人員說沒法上傳到docker hub，可能也有自己的苦衷吧。。。

二、解決方法

解決方法很簡單，用國內(nèi)好心人搬運(yùn)到docker hub上的倉庫代替

好心人的項(xiàng)目地址：https://github.com/anjia0532/gcr.io_mirror，對應(yīng)的docker hub地址：https://hub.docker.com/u/anjia0532

還可以手動(dòng)發(fā)issue讓其更新，以后gcr.io或k8s.gcr.io倉庫的都可以在此更換

所以，v1.1.1版本的修改過的鏡像的完整yaml文件如下：（我已經(jīng)幫你找好了），如果你要使用其他版本ingress控制器，請?jiān)谠揹ocker hub上自己尋找替換，如果不是最新自己發(fā)issue拉取
