哪个云区域可以最快的时间推进对接图像？

Question

TLDR如何知道云中哪个区域离码头枢纽最近？

详细信息从我的本地主机，我的网络是超级缓慢的推进码头形象到码头枢纽。

我的解决办法是使用云机器来实现docker image push，希望那里的互联网会更快。

所以我的问题是云上哪个区域离码头中心最近，我可以选择吗？

我的谷歌搜索结果没有多大帮助

附注：我还在devops姐妹网站这里上询问

从云实例中，只需推送到停靠中心；您将自动被路由到最佳位置。

registry服务器的hub.docker.com主机名

如果您的问题是公共服务器hub.docker.com，那么它就是注册表有地址 registry-1.docker.io

A-records of registry.docker.io

您可以使用dig或nslookup找到实际的DNS dig。

nslookup -type=A registry.docker.io                                                                                                                           6.66 Dur  23:22:32 
Server:         127.0.0.53
Address:        127.0.0.53#53

Non-authoritative answer:
registry.docker.io      canonical name = registry-1.docker.io.
Name:   registry-1.docker.io
Address: 52.206.192.146
Name:   registry-1.docker.io
Address: 52.87.94.70
Name:   registry-1.docker.io
Address: 52.55.198.220
Name:   registry-1.docker.io
Address: 54.152.200.115
Name:   registry-1.docker.io
Address: 54.164.50.37
Name:   registry-1.docker.io
Address: 52.2.169.2
Name:   registry-1.docker.io
Address: 52.202.253.107
Name:   registry-1.docker.io
Address: 52.201.142.14

 dig +short registry.docker.io A                                                                                                                              
registry-1.docker.io.
54.210.105.17
3.210.179.11
3.224.11.4
54.164.50.37
3.221.133.86

3.209.173.81
54.174.39.59

地理定位的ipinfo

工具用于IP地理定位，让我们使用ipinfo

例如，它最近的Cloudflare服务器的ipinfo：

curl ipinfo.io/1.1.1.1                                                                                                                                                  {
  "ip": "1.1.1.1",
  "hostname": "one.one.one.one",
  "city": "Haymarket",
  "region": "New South Wales",
  "country": "AU",
  "loc": "-33.8661,151.2040",
  "org": "AS13335 Cloudflare, Inc.",
  "postal": "2000",
  "timezone": "Australia/Sydney",
  "readme": "https://ipinfo.io/missingauth"
}

利用city和hostname提取jq

因为ipinfo以JSON格式返回答案，所以我们可以解析它。jq是完成这类任务的工具。

curl -s ipinfo.io/54.210.105.17 | jq -r '{city:.city, host:.hostname}'
{
  "city": "Virginia Beach",
  "host": "ec2-54-210-105-17.compute-1.amazonaws.com"
}

所有registry服务器最近的城市

让我们尝试为所有已解析的服务器找到最近的城市：

for addr in $(dig +short registry-1.docker.io A); do
  curl -s ipinfo.io/$addr | jq -r '{city:.city, host:.hostname}'; 
done
{
  "city": "Virginia Beach",
  "host": "ec2-3-209-173-81.compute-1.amazonaws.com"
}
{
  "city": "Virginia Beach",
  "host": "ec2-54-210-105-17.compute-1.amazonaws.com"
}
{
  "city": "Virginia Beach",
  "host": "ec2-100-24-246-89.compute-1.amazonaws.com"
}
{
  "city": "Virginia Beach",
  "host": "ec2-3-224-11-4.compute-1.amazonaws.com"
}
{
  "city": "Virginia Beach",
  "host": "ec2-54-164-50-37.compute-1.amazonaws.com"
}
{
  "city": "Virginia Beach",
  "host": "ec2-3-221-133-86.compute-1.amazonaws.com"
}
{
  "city": "Virginia Beach",
  "host": "ec2-3-210-179-11.compute-1.amazonaws.com"
}
{
  "city": "Virginia Beach",
  "host": "ec2-54-174-39-59.compute-1.amazonaws.com"
}
