阿里云Docker配置镜像源 —— 记一次Artalk部署过程的坑

想在Rocky Linux上用Docker部署Artalk，按照教程做，只得到：

Unable to find image 'artalk/artalk-go:latest' locally

迟迟没有接下来的从远端下载的过程。
DeepSeek提供了错误的镜像源地址docker.mirrors.ustc.edu.cn，自己搜索一下正确的地址就行了。执行sudo vim /etc/docker/daemon.json编辑配置：

{
        "registry-mirrors": [
                "https://docker.m.daocloud.io",
                "https://docker.1ms.run"
        ],
        "dns": ["114.114.114.114", "8.8.8.8"]
}

之后sudo systemctl restart docker后再次拉取：

Unable to find image 'artalk/artalk-go:latest' locally
latest: Pulling from artalk/artalk-go
.....
Digest: sha256:......
Status: Downloaded newer image for artalk/artalk-go:latest

就行了。
