Walkthrough

This update introduces a new GitHub Actions workflow to manually trigger the build and push of a debug pod Docker image to multiple container registries. Additionally, the GreptimeDB cluster Helm chart version has been updated from 0.2.47 to 0.2.48 with supporting documentation enhancements. A new Dockerfile and README have been added to define and explain a debug pod image based on Ubuntu 22.04 that installs essential CLI tools. Minor comments in configuration files have also been updated to reference additional debug pod documentation.

Poem

Hopping through the code with glee,
I built a pod debug, fancy and free.
Containers dance with every push and pull,
Helm charts leap as versions grow full.
From Ubuntu roots, our toolset shines bright,
A rabbit’s code-crafted delight!

    • 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.

33-39: Consider using GitHub's built-in SHA and date variables.

Instead of using git and date commands, you can use GitHub's built-in variables for a more reliable solution.

-      - name: Configure build image tag # The image tag will be like '20230116-6441c463'
-        shell: bash
-        run: |
-          buildTime=`date "+%Y%m%d"`
-          commitShortSHA=`git log -1 --pretty=format:"%h"`
-          IMAGE_TAG="$buildTime-$commitShortSHA"
-          echo "IMAGE_TAG=${IMAGE_TAG}" >> $GITHUB_ENV
+      - name: Configure build image tag
+        shell: bash
+        run: |
+          echo "IMAGE_TAG=$(date -u '+%Y%m%d')-${GITHUB_SHA::7}" >> $GITHUB_ENV

3-3: Improve readability with proper spacing.

There's a missing space between "tools" and the opening parenthesis.

-This docker image is designed for debugging purposes and includes a variety of useful tools(such as `mysql-client` and `kubectl`, etc.).

11-18: Fix list indentation and add version information.

The list indentation should be 2 spaces instead of 4. Also, consider adding version information for each tool.

 - **Tools Included**:
-    - `mysql-client`
-    - `postgresql-client`

57-57: Add a note about image availability.

The example uses a placeholder tag but doesn't mention where to find available tags.

-        - image: greptime/greptime-tool:${tag} # Replace ${tag} with the desired image tag, which you can find here: https://hub.docker.com/repository/docker/greptime/greptime-tool/tags

4-19: Consider reducing image size and adding version constraints.

The current installation might include unnecessary dependencies and unpinned versions.

 RUN apt-get update && apt-get install -y \
     wget \
     tar \
-    sudo \
     curl \
     unzip \
     net-tools \
     iproute2 \

+    postgresql-client=14.* \
     jq \
     python3 \
-    python3-pip
+    python3-pip \
+    && rm -rf /var/lib/apt/lists/*

62-62: Consider using a more appropriate entrypoint.

Using tail -f /dev/null as the CMD is a common anti-pattern.

-CMD ["tail", "-f", "/dev/null"]
+# Use a shell as the entrypoint for interactive debugging
+ENTRYPOINT ["/bin/bash"]

41-50: LGTM! Multi-platform build configuration looks good.

The build configuration correctly handles:

  • Multi-platform builds (amd64, arm64)
  • Pushing to multiple registries
  • Using environment variables for image tag
