Walkthrough

The DNS management configuration has undergone a significant overhaul, replacing the gdnsd package with the bind9 package. This includes the removal of gdnsd related configurations and the introduction of corresponding settings for bind9, such as package installation, syntax checking, and service management. The repository cloning location and monitoring configurations have also been updated or removed to align with the new DNS server software.

Changes

File Path	Change Summary
modules/dns/manifests/init.pp	Replaced gdnsd package with bind9, updated syntax checking from gdnsd-syntax to bind-syntax, changed service management from gdnsd to named, and removed monitoring configurations related to gdnsd.

Poem

🐰 In fields of code where rabbits play,
A change in DNS has come our way!
From gdnsd to bind9 we hop,
With syntax checks and services on top!
Let’s celebrate with a joyful cheer,
For a brighter DNS future is here! 🌟

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>.
  • Generate unit testing code for this file.
  • 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 generate unit testing code for this file.
  • @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 generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @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.

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.

I'm slightly concerned we don't absent the gdnsd package. What would happen if gdnsd + bind on the same host? That feels like it should cause unexpected conflicts

It would, however we can just uninstall gdnsd when we're ready for merging this.
