Sync

Sync: 定期同步列表里的 image tag 的同步率, 只要 tag 存在就是同步的.

!!!!!!!!!!!!!!!!!!!!!!!!通知!!!!!!!!!!!!!!!!!!!!!!!!

由于近期个别 Image 和 IP 存在大流量, 近期将会进行屏蔽 如果有大量需求的

背景

很多镜像都在国外。比如 gcr 。国内下载很慢,需要加速。

目标

  • 一个简洁有效的方法能够加速这些包。简洁的名称映射
  • 易于添加,添加新的包,不需要去修改代码。
  • 稳定可靠,更新实时。每天检查同步情况。

快速开始

docker run -d -P m.daocloud.io/docker.io/library/nginx

使用方法

增加前缀 (推荐方式)。比如:

k8s.gcr.io/coredns/coredns => m.daocloud.io/k8s.gcr.io/coredns/coredns

或者 支持的镜像仓库 的 前缀替换 就可以使用。比如:

k8s.gcr.io/coredns/coredns => k8s-gcr.m.daocloud.io/coredns/coredns

单次单镜像同步

!!!!!!!!!!!!!!!!!!!!!!!!强烈推荐!!!!!!!!!!!!!!!!!!!!!!!!

您可以根据 镜像同步 Issue 模板 创建一个 Issue, 将会有机器人帮您优先主动同步指定的镜像

原先已经在下的镜像还是会继续走原来的, 需要重启 docker 再重新拉取才能走已经同步好的缓存过, 所以推荐先单次同步再尝试拉取 对于 latest 这种经常内容会发生变更的 tag 变更后会需要重新同步

每个 Issue 带宽

  • 国际带宽 3 * 50 Mbps

懒加载

仅推荐用于小于 20MiB 的镜像 这条通道主要用于保持 image 是最新的, 每次拉取都会检查是否和上游保持同步

如果您看到下没有进度这是由于带宽有限只要有几人在下较大的文件就会阻塞后续的下载, 可以尝试单次单镜像同步

就算没同步也能 直接拉取, 初次拉取会比已经同步过的慢.

所有懒加载 带宽

  • 国际带宽 3 * 30 Mbps

定期同步列表

不推荐, 由于数量已经比较多了初次提交, 到被同步到需要很长时间

强烈建议使用单次单镜像同步

mirror.txt

如果想要新增, 提 PR 修改即可。例如 PR#1, 并请在 PR 提交前排序: ./hack/fmt.sh mirror.txt

支持前缀替换的 Registry

前缀替换的 Registry 的规则, 这是人工配置的, 有需求提 Issue.

源站 替换为
cr.l5d.io l5d.m.daocloud.io
docker.elastic.co elastic.m.daocloud.io
docker.io docker.m.daocloud.io
gcr.io gcr.m.daocloud.io
ghcr.io ghcr.m.daocloud.io
k8s.gcr.io k8s-gcr.m.daocloud.io
registry.k8s.io k8s.m.daocloud.io
mcr.microsoft.com mcr.m.daocloud.io
nvcr.io nvcr.m.daocloud.io
quay.io quay.m.daocloud.io
registry.jujucharms.com jujucharms.m.daocloud.io
rocks.canonical.com rocks-canonical.m.daocloud.io

最佳实践

  • 通过 加速 安装 kubeadm
kubeadm config images pull --image-repository k8s-gcr.m.daocloud.io
  • 通过 加速 安装 kind
kind create cluster --name kind --image m.daocloud.io/docker.io/kindest/node:v1.22.1
  • 通过 加速 部署 应用(这里以 Ingress 为例)
wget -O image-filter.sh https://github.com/DaoCloud/public-image-mirror/raw/main/hack/image-filter.sh && chmod +x image-filter.sh

wget -O deploy.yaml https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.1.0/deploy/static/provider/baremetal/deploy.yaml

cat ./deploy.yaml | ./image-filter.sh | kubectl apply -f -
  • Docker 加速

添加到 /etc/docker/daemon.json
