Tag: labzero-dev
Definition: containers/Containerfile.dev
Base: rust:1-bookworm

All builds, tests, and verifier runs use Podman with the repo bind-mounted at /workspace.

Tool	Source
Rust stable + clippy + rustfmt	rust:1-bookworm
Python 3 + pip deps	`verifier/python/requirements.txt`
Stockfish binary	Debian `stockfish` package (oracle/opponent only)
Fastchess	Shallow git clone + `make` in image

Container runs as --user 0:0 for bind-mount write access on macOS/Linux. Cargo artifacts: /workspace/.cargo-target.

-v "$REPO_ROOT:/workspace"   # :Z suffix on Linux SELinux
-w /workspace
-e CARGO_TARGET_DIR=/workspace/.cargo-target

Named volumes cache Cargo registry/git: labzero-cargo-registry, labzero-cargo-git.

Use Podman Desktop or podman machine init && podman machine start. Scripts omit :Z on Darwin.
