helm 国内镜像源配置

Repository（仓库） 是用来存放和共享 charts 的地方, 供 Kubernetes 包使用。

Helm 自带一个强大的搜索命令，可以用来从两种来源中进行搜索：

  • helm search hub 从 Artifact Hub 中查找并列出 helm charts。 Artifact Hub中存放了大量不同的仓库。

  • helm search repo 从你添加（使用 helm repo add）到本地 helm 客户端中的仓库中进行查找。该命令基于本地数据进行搜索，无需连接互联网。

Helm repo

helm repo 添加、列出、删除、更新和索引chart仓库

helm repo 添加仓库

helm repo add ingress-nginx https://kubernetes.github.io/ingress-nginx

ingress-nginx 拉取的是google的镜像源，在国内网络环境常常会pull失败，

这时可以尝试替换为国内镜像源，或自建私有镜像源解决。

docker 镜像源代理

docker proxy 使用文档

Google Kubernetes 常规镜像代理

    官方命令：docker pull k8s.gcr.io/username/image:tag 

    官方命令：docker pull registry.k8s.io/username/image:tag 

    代理命令：docker pull k8s.dockerproxy.com/username/image:tag

docker 通过配置文件使用镜像源代理，配置示例如下:

cat ~/.docker/daemon.json
{"registry-mirrors":["https://bmtdpkoz.mirror.aliyuncs.com","https://docker.mirrors.ustc.edu.cn"],"experimental":true,"debug":true,"features":{"buildkit":false}}%
