Greptile Overview

Greptile Summary

This PR updates the .dockerignore pattern from .git/ to **/.git, which changes the scope from excluding only the root-level .git directory to excluding .git directories at any nesting level in the build context.

Key changes:

• Pattern changed from .git/ to **/.git
• The ** glob pattern matches .git directories at any depth
• Removes the trailing slash, making it match both files and directories named .git
• Ensures .git directories from submodules or nested structures are also excluded from Docker builds

Impact:

• Reduces Docker build context size by excluding all .git directories
• Improves build performance and security by preventing unnecessary version control data from being copied into images
• More robust pattern that handles edge cases with submodules or vendored dependencies

Confidence Score: 4/5

• This PR is safe to merge with minimal risk
• The change is a simple improvement to the .dockerignore pattern that makes it more robust. It follows Docker best practices and has no functional impact on the application code. The only minor consideration is the removal of the trailing slash, which changes the pattern from directory-only to matching both files and directories, though in practice .git is always a directory.
• No files require special attention
