It combines syntax-aware parsing with rules for correctness, security, reproducibility, maintainability, and container-image performance. ### Project history The official repository was created in April 2026. The project quickly expanded from a command-line linter into a shared rule engine offered through native binaries, a container image, WebAssembly, editor integrations, pre-commit, and a GitHub Action. ### Adoption history The project supports installation through Homebrew and Cargo, direct binary releases, GHCR, Wasmer, VS Code, Neovim, and pre-commit. These surfaces let the same checks run locally, in editors, and in CI. ### How it is used Users can lint a single Dockerfile or recursively discover container build files across a repository. Output formats include terminal text, compact text, JSON, GitHub annotations, and SARIF; teams can commit a root-level droast.toml for shared defaults and policy. ### Why package nerds care droast targets packaging mistakes that affect reproducible and secure container images, including unpinned packages and base images, unsafe secrets, cache misuse, and incorrect package-manager cleanup. Its small Rust binary and multiple packaging formats make it easy to insert into existing build pipelines. ### Timeline - 2026-04: The official repository was created. - 2026-07: Version 1.4.7 was released with native, container, editor, pre-commit, CI, and WASI installation paths. ### Related projects - The project documents migration from Hadolint policies and optional ShellCheck integration, and it supports Docker and Podman build-context conventions. ### Sources - - - ## Security Notes No matching local secret-handling manifest was found for droast. Nucleus package metadata is still published here so future coverage has a stable package URL. ## Configuration and credential file locations These source-backed paths show where this package keeps local settings or durable credentials. Automic Vault can use them as review targets for secret scanning, migration, and command approval. ## Configuration files - Unix: ./droast.toml ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** droast - **Version Scheme:** 0 - **Revision:** 0 - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** stable ## Related links - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Text processing packages](https://www.automicvault.com/pkg/text-processing-tools/) - Matched text, document, or structured-data processing metadata. - [Developer build packages](https://www.automicvault.com/pkg/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [Language runtime packages](https://www.automicvault.com/pkg/language-runtime-packages/) - Matched language runtime, compiler, or interpreter metadata. - [rust](https://www.automicvault.com/pkg/brew/rust/) - Build dependency declared by Homebrew. - [actionlint](https://www.automicvault.com/pkg/brew/actionlint/) - Shares av.db curated category or tags: ci, cli, developer-tools, linting, static-analysis. - [mado](https://www.automicvault.com/pkg/brew/mado/) - Shares av.db curated category or tags: cli, developer-tools, linter, linting, rust. - [oxlint](https://www.automicvault.com/pkg/brew/oxlint/) - Shares av.db curated category or tags: cli, developer-tools, linter, linting, rust. - [protolint](https://www.automicvault.com/pkg/brew/protolint/) - Shares av.db curated category or tags: cli, developer-tools, linter, linting, static-analysis. - [quick-lint-js](https://www.automicvault.com/pkg/brew/quick-lint-js/) - Shares av.db curated category or tags: cli, developer-tools, linter, linting, static-analysis. - [sherif](https://www.automicvault.com/pkg/brew/sherif/) - Shares av.db curated category or tags: cli, developer-tools, linter, linting, rust. - [addons-linter](https://www.automicvault.com/pkg/brew/addons-linter/) - Shares av.db curated category or tags: cli, developer-tools, linter, linting. - [api-linter](https://www.automicvault.com/pkg/brew/api-linter/) - Shares av.db curated category or tags: cli, developer-tools, linter, linting. ## Combined YAML source View the package source record on GitHub.
