本文主要是介绍安装OpenEBS，镜像总是报错ImagePullBackOff或者ErrImagePull的解决方法，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
按照 KubeSphere 官方文档安装 OpenEBS，镜像总是报错ImagePullBackOff或者ErrImagePull的解决方法
helm 有很多更换 源 的文章，有一些是写更换阿里云的源，但是阿里云的源根本没更新OpenEBS的镜像。
在网上找到1个可用的源：
可用的源：
stable: http://mirror.azure.cn/kubernetes/charts/
无用的源：
http://mirror.azure.cn/kubernetes/charts-incubator/
https://kubernetes-charts.storage.googleapis.com/ 拒绝访问
https://registry.cn-hangzhou.aliyuncs.com/ 无法访问
https://quay.io/ 被墙
不可用的源执行 helm repo add … 命令会报如下错误：
[root@k8snode1 etcd]# helm repo add incubator http://mirror.azure.cn/kubernetes/charts-incubator/
WARNING: Deprecated index file format. Try 'helm repo update'
Error: Looks like "http://mirror.azure.cn/kubernetes/charts-incubator/" is not a valid chart repository or cannot be reached: no API version specified
所以把helm的源替换成上面的 http://mirror.azure.cn/kubernetes/charts/
# 先移除旧的源，如果没有添加过旧的源，请忽略
helm repo remove stable# 添加新的源
helm repo add stable http://mirror.azure.cn/kubernetes/charts/# 更新源
helm repo update
开始安装OpenEBS
helm install --namespace openebs --name openebs stable/openebs --version 1.5.0
执行命令 kubectl get pods --all-namespaces 发现 openebs的镜像总是报错ImagePullBackOff或者ErrImagePull 。
kubectl get pods --all-namespaces
执行 helm search 发现并没有 openebs 1.5.0 的镜像。
helm search
所以，上面添加了新的源也没用，还得想其他办法将 镜像 拉取到本地。
官方给出了2种安装 OpenEBS的方法：
我们先从 https://openebs.github.io/charts/openebs-operator-1.5.0.yaml 这里将 openebs-operator-1.5.0.yaml这个文件下载下来。
注：https://openebs.github.io/charts/openebs-operator-1.5.0.yaml 这个链接已经失效，打不开了。
openebs-operator-1.5.0.yaml 文件内容：

---分析上面的文件内容，我们可以看到，它需要从 quay.io 网站中 拉取这些 openebs 的镜像。但是这个网站被墙了，所以拉不下来。

所以我们上 docker hub 网站上，看看有没有 openebs 的镜像。发现是有的。
然后点进去一个看看有没有 1.5.0 版本的， 发现还是有的。
于是我们把前面 openebs-operator-1.5.0.yaml 要用到的镜像全部使用 docker pull 的方式拉取到本地。直接复制下面的命令拉取。到时候哪个拉取失败，再去 docker hub 看看是否有对应的镜像。
docker pull openebs/m-apiserver:1.5.0docker pull openebs/openebs-k8s-provisioner:1.5.0docker pull openebs/snapshot-controller:1.5.0docker pull openebs/node-disk-manager-amd64:v0.4.5docker pull openebs/node-disk-operator-amd64:v0.4.5docker pull openebs/admission-server:1.5.0docker pull openebs/provisioner-localpv:1.5.0
上面的镜像全部拉取到本地之后，就修改 openebs-operator-1.5.0.yaml 文件，将所有的 image: quay.io/ 替换为 image:
让它从本地拉取镜像。

---上面的步骤完成后，使用 kubectl apply 命令安装。

但是，使用 kubectl get pods --all-namespaces 查看，发现镜像还是报错ImagePullBackOff或者ErrImagePull 。
原因可以参考一下这篇文章《k8s所在的节点docker有镜像 为什么还要从远程拉取》。
因我只在 master 节点拉取了这些镜像，没有在 node 节点拉取，把上面的镜像再拉取一遍到 node 节点上就行了。
介绍另一种方式：
因为我昨天访问 docker hub, 结果 docker hub 也访问不了。即 docker pull 也拉取不了镜像的时候，我们可以在网上找到对应的 tar 镜像，使用 docker load 命令将 tar 镜像拉取到本地。
例子：
docker load -i openebs-k8s-provisioner_1.5.0.tar openebs-k8s-provisioner:1.5.0
可以参考这篇文章
最终效果：
最后，也可以将自己拉取下来的镜像推送到阿里云上去：
参考 阿里云文档
这篇关于安装OpenEBS，镜像总是报错ImagePullBackOff或者ErrImagePull的解决方法的文章就介绍到这儿，希望我们推荐的文章对编程师们有所帮助！
