This repository is a Docker image build system for creating customized Ubuntu-based images optimized for GitHub Actions (via nektos/act) and CI/CD workflows. It uses a parameterized Dockerfile and modular shell scripts to install specific toolsets (Java, Go, Node.js, .NET, etc.) on top of base images. The build process is orchestrated by a PowerShell script (build.ps1) that leverages Buildah for multi-arch image creation and manifest handling, with GitHub Actions automating scheduled and triggered builds. The system produces images tagged for various use cases like 'act', 'runner', 'js', 'rust', etc., pushing to multiple container registries.
The LLM identified 2 files worth highlighting for reuse:
Provides robust, reusable functions for managing /etc/environment variables (get, set, append, prepend) with proper quoting and error handling. Demonstrates advanced shell scripting techniques like delimiter-safe sed operations and environment reloading. Zero dependencies, easily extractable for any Linux system administration task.
Contains production-grade helper functions for resilient downloads with exponential backoff, GitHub release asset parsing, version comparison, and package management. Key features include dpkg-based package checks, semver sorting, and SHA verification. Used extensively across tool installation scripts, showing consistent error handling and retry logic.
