Networks in China

The installer already treats failures per hop: it names the hop that failed and the next action. You can do the same by hand.

Docker images

Official image: motricseven7/snowluma.

If Hub times out or rate-limits, pull through a prefix and retag:

docker pull docker.1ms.run/motricseven7/snowluma:latest
docker tag docker.1ms.run/motricseven7/snowluma:latest motricseven7/snowluma:latest

docker.xuanyuan.me/ and docker.m.daocloud.io/ are other public prefixes. They churn; do not treat any one of them as the only source.

On cloud VMs prefer the vendor's registry mirror. On 1Panel / Baota, set it in the panel. Do not let a script rewrite daemon.json.

Installing Docker Engine

Do not pipe random Gitee installers.

• Ubuntu/Debian: Aliyun / Tsinghua docker-ce mirrors
• The installer uses those, then get.docker.com --mirror Aliyun
• OpenCloudOS / openEuler: do not use the distro's ancient docker package

Installer script

If raw.githubusercontent.com is blocked in the one-liner:

curl -fsSL https://ghfast.top/https://raw.githubusercontent.com/SnowLuma/SnowLuma.Docker.Framework/main/install.sh | bash

Templates then come from jsDelivr / ghfast. Do not swap in a random Gitee installer.

GitHub releases (lite tarball, host mode)

github.com / objects.githubusercontent.com can stall. The host-mode installer tries ghfast, gh-proxy, then GitHub, and verifies checksums when they exist.

Do not put GitHub reverse proxies into Docker registry-mirrors.

Linux QQ packages

Use Tencent's CDN qqdl.gtimg.cn. The image build pins the current official filename plus a pinned backup; it never follows latest.
