docker 镜像下载的另一种方式

时间：2025-03-30 07:06:16

目前下载docker大家都是用proxy方式去下载,由于什么原因都懂,这里不讨论
用proxy下载方式就变成是这样,以 dockerpull.cn为例:


docker pull dockerpull.cn/nvidia/cuda:11.8.0-cudnn8-devel-ubuntu22.04
​​​​​​​docker tag dockerpull.cn/nvidia/cuda:11.8.0-cudnn8-devel-ubuntu22.04 nvidia/cuda:11.8.0-cudnn8-devel-ubuntu22.04

但并不是每次都那么幸运，要更换不同代理来来回回下载，
那么为了方便更好的下载,这里整理了一些proxy,并整理成 dockerpull 脚本,逻辑是一样，你可以这样使用,使用过程比原来的方式少输入一个空格即可:
如:

本应该这样拉:

docker pull nvidia/cuda:11.8.0-cudnn8-devel-ubuntu22.04

现在你可以这样拉

dockerpull nvidia/cuda:11.8.0-cudnn8-devel-ubuntu22.04


这样我找了一些现有已知的proxy,如你有发现新的,也可手动加上:


# 定义镜像源列表
MIRROR_LIST=(
    "dockerproxy.net"
    "cr.laoyou.ip-ddns.com"
    "docker.1panel.live"
    "image.cloudlayer.icu"
    "hub.fast360.xyz"
    "docker-0.unsee.tech"
    "docker.1panelproxy.com"
    "docker.tbedu.top"
    "dockerpull.cn"
    "docker.m.daocloud.io"
    "hub.rat.dev"
    "docker.kejilion.pro"
    "docker.hlmirror.com"
    "docker.imgdb.de"
    "docker.melikeme.cn"
    "ccr.ccs.tencentyun.com"
    "pull.loridocker.com"
    "docker.sunzishaokao.com"
    "dockerhub.icu"
    "docker.wanpeng.top"
    "docker.anyhub.us.kg"
    "docker.fxxk.dedyn.io"
)


废话不说,上dockerpull脚本,自行保存为dockerpull,并chmod +x dockerpull:

#!/bin/bash


# 检查是否提供了镜像名称参数
if [ -z "$1" ]; then
    echo "Usage: $0 <image_name:tag>"
    exit 1
fi

# 定义镜像源列表
MIRROR_LIST=(
    "dockerproxy.net"
    "cr.laoyou.ip-ddns.com"
    "docker.1panel.live"
    "image.cloudlayer.icu"
    "hub.fast360.xyz"
    "docker-0.unsee.tech"
    "docker.1panelproxy.com"
    "docker.tbedu.top"
    "dockerpull.cn"
    "docker.m.daocloud.io"
    "hub.rat.dev"
    "docker.kejilion.pro"
    "docker.hlmirror.com"
    "docker.imgdb.de"
    "docker.melikeme.cn"
    "ccr.ccs.tencentyun.com"
    "pull.loridocker.com"
    "docker.sunzishaokao.com"
    "dockerhub.icu"
    "docker.wanpeng.top"
    "docker.anyhub.us.kg"
    "docker.fxxk.dedyn.io"
)
# 用户输入的目标镜像名称
USER_INPUT_IMAGE="$1"

# 判断是否需要添加 library/ 前缀
if [[ "$USER_INPUT_IMAGE" != */* ]]; then
    TARGET_IMAGE="library/$USER_INPUT_IMAGE"
else
    TARGET_IMAGE="$USER_INPUT_IMAGE"
fi

# 提取镜像名和标签
IMAGE_NAME=$(echo "$TARGET_IMAGE" | sed 's/library\///' | sed 's/:.*//')
IMAGE_TAG=$(echo "$TARGET_IMAGE" | sed 's/.*://')


# 遍历镜像源列表
for MIRROR in "${MIRROR_LIST[@]}"; do
    echo "Trying to pull image from $MIRROR..."
    # 拉取镜像
    docker pull "$MIRROR/$IMAGE_NAME:$IMAGE_TAG"
    
    if [ $? -eq 0 ]; then
        echo "Successfully pulled image from $MIRROR/$IMAGE_NAME:$IMAGE_TAG"
        # 将镜像标签改回原始的 Docker Hub 标签
        docker tag "$MIRROR/$IMAGE_NAME:$IMAGE_TAG" "$TARGET_IMAGE"
        echo "Tagged image as $TARGET_IMAGE"
        # 删除临时镜像
        docker rmi "$MIRROR/$IMAGE_NAME:$IMAGE_TAG"
        echo "Removed temporary image $MIRROR/$IMAGE_NAME:$IMAGE_TAG"
        exit 0
    else
        echo "Failed to pull image from $MIRROR/$IMAGE_NAME:$IMAGE_TAG. Trying next mirror..."
    fi
done

echo "Failed to pull image from all mirrors."
exit 1
