Walkthrough

This pull request introduces a new GitHub Action, "Free Disk Space", which executes a composite run strategy to display disk usage before cleanup, remove specified unnecessary directories, and then display the disk usage after cleanup. Additionally, several scripts and workflows related to container image building, pushing, manifest management, and artifact fetching have been removed from the repository.

Changes

File(s) Change Summary
.github/actions/free-disk-space/action.yaml Added a new GitHub Action that displays disk usage before cleanup, removes specific directories using sudo rm -rf, and displays disk usage after cleanup.
.github/workflow-scripts/buildah-build-and-push-manifest.sh, .github/workflows/build-bootc.yaml, .github/workflows/build-rhel-bootc.yaml, Makefile, fetch-artifact.sh Removed CI/CD workflows and scripts for building, managing, and pushing container images, including manifest handling, Bootc image builds, and artifact fetching.

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.

11-19: Disk Cleanup Command & Safety Considerations
The "Free disk space" step uses a multi-line command to remove directories deemed unnecessary on the runner. A few points to consider:

  • Directory Verification: Ensure that each directory (including the environment variable $AGENT_TOOLSDIRECTORY) is indeed safe for deletion in your CI context.

  • Guarding Against Accidental Deletion: It might be beneficial to add a check ensuring that $AGENT_TOOLSDIRECTORY is not empty. For example, you could modify the command to conditionally remove this directory:

    -    - name: Free disk space
    -      run: |
    -        sudo rm -rf \
    -          "$AGENT_TOOLSDIRECTORY" \
    -          /opt/ghc \
    -          /usr/local/lib/android \
    -          /usr/local/share/boost \
    -          /usr/share/dotnet
    +    - name: Free disk space
    +      run: |
    +        [ -n "$AGENT_TOOLSDIRECTORY" ] && sudo rm -rf "$AGENT_TOOLSDIRECTORY"
    +        sudo rm -rf \
    +          /opt/ghc \
    +          /usr/local/lib/android \
    +          /usr/local/share/boost \
    +          /usr/share/dotnet
  • Logging: Optionally, adding some echo statements to log which directories are being removed can ease troubleshooting and verification during CI runs.

1-4: File Header & Metadata
The header and metadata are well-formed. The action’s name and description clearly articulate its purpose.


5-7: Composite Run Setup
The composite run configuration under the runs key is correctly set up, and the structure provides a clear sequence of steps for this action.


8-10: Pre-Cleanup Disk Usage Snapshot
The "Disk space before" step uses df -h appropriately to capture disk usage prior to cleanup. This provides a useful baseline for later comparison.


20-22: Post-Cleanup Disk Usage Snapshot
The final step executes df -h again to verify the effect of the cleanup. This is a good practice for confirming that disk space has been freed.
