Walkthrough

The changes involve modifications to several files, primarily enhancing the dependency installation process in the GitHub Actions workflow for building on Ubuntu. New Kubernetes component definitions for a Pika exporter and Redis Sentinel are added, specifying service configurations and deployment details. Additionally, a new Helm template for Grafana dashboards is introduced, which dynamically generates ConfigMaps based on JSON files.

1-19: LGTM! Well-structured template for Grafana dashboards.

The overall structure and approach of this Helm template are well-designed. It efficiently generates ConfigMaps for Grafana dashboards based on JSON files in the 'dashboards' directory. This approach allows for easy management and deployment of dashboards as part of the Helm chart.

A few observations and suggestions:

1. The naming convention used for ConfigMaps (line 11) is good, as it includes the chart name and dashboard name. The use of trunc 63 | trimSuffix "-" ensures compliance with Kubernetes naming conventions.

2. The labels (lines 12-15) are appropriately set, making it easy to identify and manage these ConfigMaps. The grafana_dashboard: "1" label is particularly useful for Grafana to auto-discover these dashboards.

3. The inclusion of dashboard data (line 17) is done correctly, using toJson to properly format the JSON content.

Consider adding a comment at the top of the file explaining the purpose of this template, for better maintainability.

Regarding the yamllint error, it's likely a false positive due to the Helm templating syntax. To verify this, you can run:

This will render the template and show any actual YAML syntax errors if they exist.

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.
  • 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 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 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.
