<div class="content">
<p>为了加速镜像拉取，你可以使用以下命令设置 registry mirror:</p>
<pre><code>sudo tee /etc/docker/daemon.json <<EOF
{
"registry-mirrors": ["https://docker.mxdyeah.top"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker</code></pre>
<p>Cloudflare 的 Workers用量有限,为避免耗尽你可以手动 pull 镜像然后 re-tag 之后 push 至本地镜像仓库。</p>
<hr />
<h2>操作示例（根据实际需要替换对应的镜像）：</h2>
<p>1. 拉取镜像</p>
<pre><code>docker pull docker.mxdyeah.top/library/alpine:latest</code></pre>
<p>2. 重命名镜像</p>
<pre><code>docker image tag docker.mxdyeah.top/library/alpine:latest library/alpine:latest</code></pre>
<p>3. 删除镜像</p>
<pre><code>docker rmi docker.mxdyeah.top/library/alpine:latest</code></pre>
