ci: add GitHub Actions workflow (build, clippy, tests, cargo audit, docker) - #18
Conversation
…ocker) The repository had no CI. Adds three jobs on push to main and on pull requests: native fmt/build/clippy/test plus the guest workspace's tests and clippy for wasm32-wasip2; `cargo audit` over both workspaces; and a Docker image build (no push) so the multi-stage Dockerfile stays green.

📝 WalkthroughWalkthroughThe pull request adds a GitHub Actions workflow for Rust validation, guest module checks, dependency auditing, and Docker image builds. The workflow runs on pushes to ChangesCI workflow
Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🟡 Moderate · up to The CI workflow leaves its repository token available to build and test code without explicitly limiting its permissions.

official Docker GitHub Actions cache backend gha required permissions cache-to type=gha
💡 Result:
When using the Docker buildx gha (GitHub Actions) cache backend with cache-to=type=gha, you generally do not need to manually configure specific permissions if you are running within a standard GitHub Actions workflow context using the official docker/build-push-action [1][2]. In a standard GitHub Actions workflow, the necessary environment variables ($ACTIONS_CACHE_URL and $ACTIONS_RUNTIME_TOKEN) are automatically populated by the runner, allowing the gha backend to authenticate and communicate with the GitHub Actions Cache API [1][2][3]. However, if you are invoking docker buildx commands manually (i.e., not using docker/build-push-action) or encounter permission-related issues, the following requirements apply: 1. Automatic Context: The gha backend relies on the GitHub Actions environment. If you are running builds outside of a GitHub Actions workflow, this backend will not function as the required runtime tokens and URLs will not be available [2][3]. 2. GitHub Token (ghtoken): If you need to specify a GitHub token manually (using the ghtoken parameter), it must have the repo scope [1]. This scope is necessary to access the GitHub Actions cache API, especially if you are performing cross-repository cache operations or the default provided token is insufficient [1]. 3. Workflow Permissions: When using the docker/build-push-action, the ghtoken parameter is automatically set to the value of secrets.GITHUB_TOKEN [1]. Ensure that your workflow has the appropriate permissions defined. In your workflow YAML, you may need to explicitly grant write access to the cache: permissions: actions: write contents: read 4. Important Version Requirements: As of April 15, 2025, the legacy GitHub Cache service API v1 has been shut down [2]. You must ensure you are using up-to-date versions of your tools to support the v2 API [2]: - Docker Buildx >= v0.21.0 - BuildKit >= v0.20.0 - Docker Compose >= v2.33.1 - Docker Engine >= v28.0.0 (if using the Docker driver with containerd image store enabled) [2] If you are using self-hosted runners, you are responsible for ensuring that the Docker/BuildKit versions on those runners meet these requirements [2].

🌐 Web query:
site:docs.github.com actions cache GITHUB_TOKEN permissions actions write cache save
💡 Result:
The GITHUB_TOKEN is automatically used by the official actions/cache action to handle cache operations [1]. It does not require you to manually configure or pass explicit permissions to the actions/cache action in your workflow file for it to function [2][1]. However, there are important security and configuration considerations regarding cache access and permissions: 1. Automatic Handling: The actions/cache action handles authentication internally. It uses the GITHUB_TOKEN provided by the runner environment to perform cache operations [2][3]. 2. Default Permissions: The GITHUB_TOKEN permissions are determined by the repository or organization settings (either permissive or restricted) [4][5]. If your GITHUB_TOKEN has been configured with restricted permissions, ensure that the actions scope has appropriate access if you are encountering issues, though in standard configurations, the actions/cache tool functions without manual permission overrides [4]. 3. Security Constraints: GitHub enforces restrictions on cache writes to prevent cache poisoning [1]. Workflows triggered by events that can be initiated by users without write access to the repository (such as pull requests from forks) are generally given read-only access to the cache [1]. These workflows can restore existing caches but cannot create or overwrite them [1]. 4. Explicit Permissions: If you ever need to manually adjust permissions for a job—for example, if you are performing custom cache operations via the GitHub API—you can use the permissions key in your workflow file [2][5]: permissions: actions: write contents: read For most standard use cases where you are simply using the official actions/cache action, no explicit permissions configuration is required [2].

Set explicit least-privilege workflow permissions.
The jobs only require repository read access. The Docker type=gha cache uses runner-provided cache credentials and does not require repository write access. Add a top-level permissions block so unspecified token permissions are disabled.

Disable checkout credential persistence.
Each checkout leaves GITHUB_TOKEN in .git/config. Later build, test, audit, and Docker steps execute repository-controlled code. A malicious change could read and reuse that token. Set persist-credentials: false on all three checkout steps.
