build: devcontainer support #2179
Conversation
WalkthroughThe changes introduce a new Dockerfile and a configuration file for a development container tailored for the Dash Platform project. The Dockerfile sets up an environment based on the official VS Code Rust image, installing essential dependencies and tools, including Protocol Buffers and the Changes

1-2: Good choice of base image, consider using a more specific tag.The selection of the official VS Code dev container image for Rust is appropriate and aligns well with the PR objectives. It provides a solid foundation for Rust development in a containerized environment.
Consider using a more specific tag for the base image to ensure better reproducibility. For example, you could use a tag that includes the patch version:
- FROM mcr.microsoft.com/devcontainers/rust:1-1-bullseye + FROM mcr.microsoft.com/devcontainers/rust:1-1-1-bullseyeThis change would pin the image to a specific patch version, reducing the risk of unexpected changes in future builds.
4-16: Good dependency selection, consider improving cache handling.The list of installed dependencies is comprehensive and appropriate for a Rust development environment. Combining
apt-get updateandapt-get installin a single RUN instruction is a good practice for reducing image layers.To prevent issues with outdated package cache, consider adding
apt-get cleanand removing the apt lists. This will reduce the image size and ensure fresh package information in future builds. Here's a suggested modification:RUN apt-get update && apt-get install -y \ build-essential \ libssl-dev \ pkg-config \ clang \ cmake \ llvm \ curl \ gnupg \ lsb-release \ software-properties-common \ - unzip + unzip \ + && apt-get clean \ + && rm -rf /var/lib/apt/lists/*This change ensures that the package cache doesn't persist in the image, potentially causing issues with future package installations.
18-21: Protoc installation looks good, consider adding integrity verification.The installation of Protoc is straightforward and uses a pinned version, which is excellent for reproducibility. The cleanup of the zip file after extraction is a good practice for keeping the image size down.
To enhance security, consider adding a step to verify the integrity of the downloaded Protoc file. You can do this by checking the SHA-256 hash of the file against the official hash provided by the Protobuf releases page. Here's an example of how you could modify the installation:
+ ARG PROTOC_SHA256=2497d8e22854d9f5ecf9e8f5a70eed7d75b3e6f5a2a0b20b50c44d8c8e7fb6e9 RUN curl -OL https://github.com/protocolbuffers/protobuf/releases/download/v25.2/protoc-25.2-linux-x86_64.zip \ + && echo "${PROTOC_SHA256} protoc-25.2-linux-x86_64.zip" | sha256sum -c - \ && unzip protoc-25.2-linux-x86_64.zip -d /usr/local \ && rm protoc-25.2-linux-x86_64.zipThis change adds a verification step to ensure the integrity of the downloaded file before installation.
23-24: wasm-bindgen-cli installation is correct, consider optimizing.The installation of wasm-bindgen-cli using Cargo is appropriate, and pinning the version ensures reproducibility.
To optimize the installation process and reduce the final image size, consider the following modifications:
- Use the
--rootoption to install the binary to a specific directory.- Only copy the binary to the final image location.
- Clean up the Cargo cache after installation.
Here's an example of how you could modify the installation:
- RUN cargo install [email protected] + RUN cargo install --root /tmp/wasm-bindgen [email protected] \ + && cp /tmp/wasm-bindgen/bin/wasm-bindgen /usr/local/bin/ \ + && rm -rf /tmp/wasm-bindgen \ + && rm -rf $CARGO_HOME/registryThese changes will significantly reduce the size of the final image and speed up subsequent build steps.

7-20: Consider adding VS Code settings for improved developer experience.The specified extensions are relevant and will enhance the development environment. However, the
settingsobject is currently empty. Consider adding project-specific VS Code settings to further improve the developer experience and ensure consistency across the team.You might want to add some common settings, for example:
"settings": { "editor.formatOnSave": true, "editor.codeActionsOnSave": { "source.fixAll.eslint": true }, "rust-analyzer.checkOnSave.command": "clippy" }

.devcontainer/Dockerfile (1)
1-24: Overall, the Dockerfile is well-structured and achieves the PR objectives.This Dockerfile successfully sets up a development environment for Rust with the necessary tools and libraries, including Protoc and wasm-bindgen-cli. It aligns well with the PR objectives of supporting devcontainers and improving the development experience.
The use of a specific base image, pinned versions for tools, and comprehensive dependency installation contributes to a reproducible and consistent development environment. This will greatly facilitate onboarding new developers and improve integration with tools like GitHub Codespaces and Copilot Workspace.
While the current implementation is functional, the suggested optimizations in the previous comments (if implemented) would further enhance the Dockerfile by:
- Improving reproducibility with more specific image tags
- Enhancing security through integrity checks
- Reducing the final image size
- Optimizing the build process
These improvements would result in a more efficient and secure development container, further supporting the goals of this pull request.
.devcontainer/devcontainer.json (3)
1-6: LGTM: Basic container configuration is well-defined.The container name is descriptive, and the build configuration using a Dockerfile with the correct context is appropriate for customizing the development environment.
21-21: LGTM: Remote user configuration is appropriate.Setting the remote user to "vscode" aligns with VS Code's defaults and is a good practice for dev containers.
22-35: Verify Rust version and Yarn installation decision.The features configuration looks good overall and includes necessary tools for the project. However, there are two points to consider:
Rust version 1.80 is specified, which is recent but not the latest stable version. Verify if this specific version is required or if you want to use the latest stable version.
Yarn installation is explicitly disabled. Confirm if this is intentional, as Yarn is commonly used in Node.js projects for package management.
To check the latest stable Rust version, you can run:
#!/bin/bash # Fetch the latest stable Rust version curl -sSf https://static.rust-lang.org/releases.json | jq -r '.[] | select(.stable == true) | .version' | head -n1To verify if Yarn is used in the project, you can search for Yarn-related files:
#!/bin/bash # Check for Yarn-related files fd -H '^yarn\.lock$|^\.yarnrc(\.yml)?$'

💡 Codebase verification
Update wasm-bindgen-cli to the latest version (0.2.93)
The current postCreateCommand installs [email protected], while the latest available version is 0.2.93. Updating to the latest version can provide important bug fixes and improvements.
- Recommendation: Update the version to
0.2.93unless there are specific compatibility reasons to remain on0.2.85.
🔗 Analysis chain
Verify if pinning wasm-bindgen-cli version is necessary.
Installing wasm-bindgen-cli is appropriate given the WebAssembly target in the Rust configuration. However, the version is pinned to 0.2.85.
Consider if this specific version is required for compatibility reasons. If not, you might want to allow for newer versions to benefit from bug fixes and improvements.
To check the latest version of wasm-bindgen-cli, you can run:
