Poem

A rabbit hopped with Docker cheer,
"Mirror me, and pull with speed,
Edit your daemon, have no fear,
Restart the service, let images lead!
With mirrors set, your pulls will race—
Docker dreams in every place!" 🐇🐳

🪧 Tips

Chat

There are 3 ways to chat with CodeRabbit:

Review comments: Directly reply to a review comment made by CodeRabbit. Example:
- I pushed a fix in commit <commit_id>, please review it.
- Explain this complex logic.
- Open a follow-up GitHub issue for this discussion.
Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
- @coderabbitai explain this code block.
- @coderabbitai modularize this function.
PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
- @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
- @coderabbitai read src/utils.ts and explain its main purpose.
- @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
- @coderabbitai help me debug CodeRabbit configuration file.

Support

Need help? Create a ticket on our support page for assistance with any issues or questions.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.

70-80: Consider clarifying HTTPS requirement & optional trailing slash.

Docker will refuse to talk to mirrors served over plain HTTP unless the user also configures insecure-registries; your example already uses HTTPS but it might not be obvious that TLS is mandatory.
Additionally, some users host the proxy behind a reverse-proxy that emits a 301 redirect to the canonical URL ending with a /. In that case Docker will silently ignore the mirror. You can save users a debugging round-trip by explicitly showing the trailing slash in the sample or adding a note that no redirects are allowed.

Example tweak:
-    "https://yourdomain.com"
+    "https://yourdomain.com/"
A short sentence like “确保使用 https，并且 URL 不要发生 301/302 跳转” right after the JSON snippet would be enough.

82-84: Add a reminder to validate JSON when multiple mirrors are present.

Many people copy-paste this fragment into an existing daemon.json that already contains other keys; a missing comma after the closing bracket of "registry-mirrors" is a common pitfall that prevents Docker from starting.
Appending a quick note such as “如果 daemon.json 还有其他字段，请确保正确添加逗号，保持合法 JSON” will spare users from a service-startup failure.
