Verify Dockerfile for Rust 1.87 exists
Ensure that dockerfiles/rust-1.87.Dockerfile is committed and referenced by any CI or build pipelines.

Ensure CI workflows include the new Rust 1.87 Dockerfile
We’ve confirmed that dockerfiles/rust-1.87.Dockerfile is present, but no references to it were found in any CI or GitHub Actions workflow files. Please update your pipeline configurations to build/test with the Rust 1.87 image.

• File location: dockerfiles/rust-1.87.Dockerfile
• No matches in .github/ workflows or other CI configs
• Action: Add or update your CI manifests (e.g. .github/workflows/*.yml) to reference this new Dockerfile so Rust 1.87 is properly built and tested.

In compiled_starters/rust/README.md at line 32, the documentation mentions Rust
1.87 but there is no corresponding update in the CI or GitHub Actions workflows
to use the new dockerfiles/rust-1.87.Dockerfile. To fix this, locate your CI
pipeline configuration files (e.g., in .github/workflows/) and add or update the
workflow steps to reference and build/test using the rust-1.87 Dockerfile,
ensuring Rust 1.87 is properly integrated into your build and test processes.

1. Run `./your_program.sh` to run your program, which is implemented in
`src/main.rs`. This command compiles your Rust project, so it might be slow
the first time you run it. Subsequent runs will be fast.

🛠️ Refactor suggestion

⚠️ Potential issue

Invalid COPY flag: --exclude will break the build.
Docker’s COPY doesn’t support --exclude; this will error out (Hadolint DL1000). Use a .dockerignore to exclude files instead of flags.

Apply this diff:

-COPY --exclude=.git --exclude=README.md . /app
+COPY . /app

And ensure your project root contains a .dockerignore with:

.git
README.md

[error] 9-9: invalid flag: --exclude

(DL1000)

🤖 Prompt for AI Agents
In dockerfiles/bun-1.2.Dockerfile at line 9, the COPY command uses the
unsupported --exclude flag, which causes build errors. Remove the --exclude
flags from the COPY command so it simply copies all files from the current
directory to /app. Then, create a .dockerignore file in the project root listing
.git and README.md to exclude these files from the build context.


# For reproducible builds.
# This will install the exact versions of each package specified in the lockfile.
# If package.json disagrees with bun.lockb, Bun will exit with an error. The lockfile will not be updated.
RUN bun install --frozen-lockfile

# If the node_modules directory exists, move it to /app-cached
RUN mkdir -p /app-cached
RUN if [ -d "/app/node_modules" ]; then mv /app/node_modules /app-cached; fi

⚠️ Potential issue

Invalid --exclude flag in COPY instruction
Docker’s COPY does not support --exclude—even with BuildKit labs enabled—so this will break your build. Remove the --exclude flags and use a .dockerignore file instead.

Apply this diff:

-COPY --exclude=.git --exclude=README.md . /app
+COPY . /app

And ensure your .dockerignore includes:

.git
README.md

[error] 10-10: invalid flag: --exclude

(DL1000)

🤖 Prompt for AI Agents
In dockerfiles/rust-1.86.Dockerfile at line 10, the COPY instruction incorrectly
uses the unsupported --exclude flag, which causes the build to fail. Remove the
--exclude flags from the COPY command so it simply copies the current directory
to /app. Then create or update the .dockerignore file in the build context root
to include .git and README.md, ensuring these files are excluded from the build
context instead of using --exclude in COPY.

⚠️ Potential issue

Invalid --exclude flag in COPY instruction
As above, Docker’s COPY doesn’t support --exclude. Replace with a simple COPY . /app and manage exclusions via .dockerignore.

-COPY --exclude=.git --exclude=README.md . /app
+COPY . /app

Ensure .dockerignore has:

.git
README.md
📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

🤖 Prompt for AI Agents
In dockerfiles/rust-1.87.Dockerfile at line 10, the COPY instruction incorrectly
uses the unsupported --exclude flag. Replace the COPY line with a simple COPY .
/app and add the excluded files and directories (.git and README.md) to a
.dockerignore file in the build context to prevent them from being copied.
