go-hadolint

go-hadolint is a distribution of hadolint, that can be built with Go. It does not actually reimplement any functionality of hadolint in Go, instead compiling it with the GHC WASI backend, and executing with the pure Go Wasm runtime wazero. This means that go install or go run can be used to execute it, with no need to rely on separate package managers such as pnpm, on any platform that Go supports.

Installation

Precompiled binaries are available in the releases. Alternatively, install the plugin you want using go install.

$ go install github.com/wasilibs/go-hadolint/cmd/hadolint@latest

To avoid installation entirely, it can be convenient to use go run

$ go run github.com/wasilibs/go-hadolint/cmd/hadolint@latest *.sh

Due to potential build breakage unrelated to this project, go tool is not supported.

Note that due to the sandboxing of the filesystem when using Wasm, currently only files that descend from the current directory when executing the tool are accessible to it, i.e., ../docker/Dockerfile or /separate/root/Dockerfile will not be found.
