Its history is short but well documented through official release notes and GitHub releases. ### Project history The project presents itself as a stateless logical dump proxy that does not require database schema changes and remains compatible with familiar PostgreSQL tools such as pg_restore. That design places it closer to backup and staging-data infrastructure than to an application-level masking library. The v0.1.0 release notes describe the January 2024 release as the first production-ready version, with CI/CD, a Docker Compose playground, transformer improvements, JSON-line protocol fixes, and binary assets. The v0.2.0 release notes describe an October 2024 milestone focused on database subsetting, pgzip compression, topological restore order, INSERT-format restoration, dynamic transformer parameters, and transformer-engine refactoring. ### Adoption history Greenmask entered package-manager culture as a CLI for teams that need repeatable sanitized databases for staging, analytics, and development. The batch package facts show Homebrew and Nix packaging, while upstream distributes release assets, Docker-oriented workflows, and documentation that emphasizes CI/CD integration. ### How it is used Greenmask is used around logical backup and restore flows: dump a database, apply transformations or subsets, store the result locally or in S3-compatible storage, and restore into another environment. The documentation emphasizes deterministic transformers, dynamic parameters, validation output, schema diff checks, and compatibility with PostgreSQL dump/restore routines. The default configuration convention in the batch curation is config.yml, matching the project's example configuration style. ### Why package nerds care Greenmask matters to package users because it packages a messy operational workflow into one repeatable binary: masked dumps, synthetic data, subsetting, restore order, and storage backends. That makes it attractive for development environments where production-like data is useful but raw production data is unsafe. For Homebrew-style packaging, it is also a representative modern Go CLI: single binary, release assets, Docker examples, and docs-first operational commands. ### Timeline - 2024: v0.1.0 release notes marked the first production-ready version. - 2024: v0.2.0 added database subsetting, pgzip support, topological restore order, and transformer refactoring. - 2025: v1.0.0b1 release metadata appeared for the 1.0 beta line. - 2026: v0.2.x releases continued through v0.2.21 in the official GitHub release feed. ### Related projects - PostgreSQL pg_dump and pg_restore are central compatibility references in the documentation. - Docker Compose, MinIO, and S3-compatible storage appear in the official examples and feature descriptions. - Transformer concepts such as random, hash, template, and CMD transformers form the project's internal extension surface. ### Sources - - - - - ## Security Notes No matching local secret-handling manifest was found for greenmask.
