dev-toolchain

DevRail v1 is stable. See STABILITY.md for component status.

DevRail developer toolchain container image — a single Docker image containing all linters, formatters, security scanners, and test runners for Python, Bash, Terraform, Ansible, Ruby, Go, JavaScript/TypeScript, and Rust projects.

Quick Start

1. Pull the image:

   docker pull ghcr.io/devrail-dev/dev-toolchain:v1

2. Run checks against your project:

   docker run --rm -v "$(pwd):/workspace" -w /workspace ghcr.io/devrail-dev/dev-toolchain:v1 make _check

3. Or use the Makefile in your DevRail-configured project:

   make check

Configuration

Projects configure their language support via .devrail.yml:

languages:
  - python
  - bash
  - terraform
  - ansible
  - ruby
  - go
  - javascript
  - rust

Architecture

• Base image: Debian bookworm-slim (multi-arch: amd64 + arm64)
• Go builder stage: Compiles Go-based tools (tflint, terraform-docs, etc.)
• Rust builder stage: Provides Rust toolchain and cargo-audit/cargo-deny via cargo-binstall
• Modular install scripts: One script per language ecosystem
• Shared libraries: lib/log.sh (logging) and lib/platform.sh (platform detection)
