📝 Walkthrough

Walkthrough

The Dockerfile was updated to modify the Java runtime command used to start the application. Specifically, the JVM option -XX:+UseZGC, which enables the Z Garbage Collector, was removed from the final CMD instruction. All other configurations, including the system property for the WebP binary directory and the execution of Stickerify.jar, remain unchanged. No other parts of the Dockerfile or application code were altered.

Poem

A Dockerfile change, neat and quick,
The ZGC flag, we did unpick.
Java still runs, with stickers in tow,
But now with one less JVM show.
The rabbit hops on, with a lighter load,
Ready to launch in its Docker abode!

🪧 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>, 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.

31-31: Optional: Explicitly specify GC or surface JVM flags
Although G1 is the current default, you may want to pin it via -XX:+UseG1GC to guard against future JDK GC changes. For greater flexibility, consider an entrypoint script that injects additional flags from an environment variable (e.g. JAVA_OPTS).

31-31: Approve removal of ZGC flag for broader compatibility
Removing -XX:+UseZGC ensures the distroless JRE can run without unmet GC dependencies—modern JDKs default to G1 GC, which is stable and well‑tested.
