Speed up generation by removing all cruft from builder #821

mkysel · 2025-05-19T15:27:19Z

Optimize Docker build context by implementing whitelist-based file inclusion in .dockerignore to speed up generation

Changes the Docker build context configuration from a blacklist to a whitelist approach in .dockerignore. The file now ignores everything by default and selectively includes only:

Go module files (go.mod, go.sum)
Go source files (*.go, excluding test files)
pkg directory and contents
tools directory and contents

Minor cleanup in Dockerfile and Dockerfile-cli removing redundant comments.

📍Where to Start

Start with the .dockerignore file which contains the core changes to the build context configuration.

Walkthrough

The .dockerignore file was restructured to ignore all files by default and then selectively allow necessary files and directories, effectively switching to a whitelist approach. Both dev/docker/Dockerfile and dev/docker/Dockerfile-cli had a comment line removed, with no changes to their build logic or functionality.

Changes

File(s)	Change Summary
.dockerignore	Changed from explicit ignore patterns to a default-ignore-all with selective allow (whitelist) pattern.
dev/docker/Dockerfile, dev/docker/Dockerfile-cli	Removed a comment line before the build command; no functional or logic changes.

Sequence Diagram(s)

No sequence diagram is generated as the changes are limited to configuration and comments, with no impact on control flow or feature logic.

Note

⚡️ AI Code Reviews for VS Code, Cursor, Windsurf

CodeRabbit now has a plugin for VS Code, Cursor and Windsurf. This brings AI code reviews directly in the code editor. Each commit is reviewed immediately, finding bugs before the PR is raised. Seamless context handoff to your AI code agent ensures that you can easily incorporate review feedback.

Note

⚡️ Faster reviews with caching

CodeRabbit now supports caching for code and dependencies, helping speed up reviews. This means quicker feedback, reduced wait times, and a smoother review experience overall. Cached data is encrypted and stored securely. This feature will be automatically enabled for all accounts on May 16th. To opt out, configure Review - Disable Cache at either the organization or repository level. If you prefer to disable all data retention across your organization, simply turn off the Data Retention setting under your Organization Settings.
Enjoy the performance boost—your workflow just got faster.

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.
- Explain this complex logic.
- 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 explain this code block.
- @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 explain its main purpose.
- @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.

20-21: Confirm test files exclusion aligns with build process.

The final pattern (**/*_test.go) ignores all Go test files from the build context. Double-check that no Docker build stage or CI step inside the container relies on test sources; otherwise, builds will fail.

Reduce Docker build context size by implementing whitelist-based file inclusion in .dockerignore

Restructures .dockerignore to use a whitelist approach, defaulting to ignore all files (**) and selectively including only go.mod, go.sum, *.go files, pkg/ and tools/ directories
Removes redundant comments from Dockerfile and Dockerfile-cli

📍Where to Start

Begin by reviewing the whitelist configuration in .dockerignore which defines the new Docker build context inclusion rules
