chore: update Haskell Dockerfile for improved caching and dependency … #121
Conversation
…management - Added environment variable to ensure container rebuilds when dependency files change. - Adjusted COPY commands to prevent cache misses by excluding .git and README.md. - Removed unnecessary dummy content and streamlined the build process.
WalkthroughThe Dockerfile for the Haskell application has been updated to streamline the build process. Key modifications include reordering environment variable declarations, changing the working directory setup, and adjusting the COPY command to include all files from the current directory. Additionally, commands that created dummy static content and an echo-based build script have been removed, and a cleanup command now removes unnecessary files to ensure a cleaner build context.

3-4: Update the comment to reflect Haskell dependency files.The comment currently states “Ensures the container is re-built if go.mod or go.sum changes,” which is misleading for a Haskell project. Since the
ENV CODECRAFTERS_DEPENDENCY_FILE_PATHSvariable listsstack.yaml,package.yaml,stack.yaml.lock, please update the comment accordingly (e.g., “Ensures the container is re-built if dependency files (stack.yaml, package.yaml, or stack.yaml.lock) change”).

15-19: Effective caching strategy with adjusted COPY.The reordering with the
WORKDIR /appdeclaration and the subsequentCOPY . /app/followed by removal of.gitandREADME.mdis a solid approach to prevent cache misses. Ensure that similar Dockerfiles in your projects adopt this improved pattern to maintain consistency.
22-29: Verify caching and cleanup steps.The steps following the build—running
stack build, cleaning up withstack clean, moving cache directories to/app-cached, and removing/app/app—are well-structured and align with the intent to streamline the Docker build context. It would be beneficial to double-check that moving and removing these directories do not interfere with subsequent build or runtime operations.
