Poem

🐰 In the garden where data grows,
New secrets bloom, as the password flows.
Clickhouse hops with a joyful cheer,
Version four is finally here!
With roles and rights, we dance and play,
Secure and bright, come what may! 🌼

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.

1-19: LGTM! The Kubernetes Role configuration looks good.

The file defines a Kubernetes Role named {{ .Release.Name }}-dashboard-resources that grants specific permissions:

  • get, list, and watch permissions on the chi-clickhouse-test-clickhouse-0-0 service resource.
  • get, list, and watch permissions on the {{ .Release.Name }}-credentials secret resource.

The configuration follows the expected structure for defining rules and permissions in a Kubernetes Role.

Regarding the yamllint hint:

[error] 4-4: syntax error: expected <block end>, but found '<scalar>'

This appears to be a false positive, as line 4 is correctly formatted. You can safely ignore this hint.

The code changes for handling user passwords are approved. The logic for generating random passwords when no password is provided is a good security practice.
