Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[0.4.6] - 2026-04-01

Changed

  • Automated patch release — version bump to 0.4.6.

[0.4.5] - 2026-03-21

Changed

  • Automated patch release — version bump to 0.4.5.

[0.4.4] - 2026-03-21

Changed

  • Automated patch release — version bump to 0.4.4.

[0.4.3] - 2026-03-21

Changed

  • Automated patch release — version bump to 0.4.3.

[0.4.2] - 2026-03-18

Fixed

  • scaffold sre empty slos: [] when --slo-type error_rate — generate_slo_manifest() in cli/scaffold_sre.py had no branch for the error_rate SLO type, leaving slo.yaml with an empty slos: [] list. Sloth/OpenSLO tooling therefore received no SLO objectives. A dedicated error_rate SLO entry (with matching SLI queries and alerting config) is now generated when --slo-type error_rate is specified.

[0.4.1] - 2026-03-17

Changed

  • Automated patch release — version bump to 0.4.1.

[0.4.0] - 2026-03-15

Added

  • scaffold unittest subcommand — new devopsos scaffold unittest command that generates unit testing configuration files and sample test stubs for multiple tech stacks:
    • Python → pytest.ini (with pytest-cov options), conftest.py with shared fixtures, tests/__init__.py, and tests/test_sample.py with parametrized examples.
    • JavaScript → Jest (jest.config.js), Vitest (vitest.config.js), or Mocha (.mocharc.js) configuration plus a matching tests/sample.test.js.
    • TypeScript → same as JavaScript with TypeScript-specific Jest transform (ts-jest) and tests/sample.test.ts.
    • Go → table-driven <name>_test.go sample and Makefile.test with test, test-race, test-cov, and lint targets.
    • Coverage configuration is included by default and can be disabled with --no-coverage.
    • Supports comma-separated --languages to scaffold multiple stacks at once.
  • generate_unittest_config MCP tool — exposes the new unit-test scaffold as an MCP tool so AI assistants can generate test configurations via conversation.
  • cli/scaffold_unittest.py — the scaffold library backing the new command.
  • docs/CLI-COMMANDS-REFERENCE.md — new section documenting all unittest options, output files, and examples.

0.3.0 - 2026-03-10

Fixed

  • scaffold gitlab empty stages when --type deploy without --kubernetes — scaffold_gitlab.py _global_section() previously excluded the deploy stage from the stages list whenever the --kubernetes flag was absent, producing an invalid pipeline. The condition is now corrected so that --type deploy always adds the deploy stage regardless of the Kubernetes flag.
  • Missing deploy job when --type deploy without --kubernetes — _deploy_job() previously returned an empty dict when kubernetes=False, leaving the pipeline with a declared deploy stage but no corresponding job. A generic deploy stub (with branch-based rules) is now returned instead, giving users a ready-to-customise deployment step out of the box.

Added

  • GitHub star count badge in README — the project README now displays a live GitHub Stars badge alongside the existing license and version badges.

0.2.0 - 2026-03-08

Fixed

  • scaffold cicd broken subprocess calls — scaffold_cicd.py previously invoked github-actions-generator-improved.py and jenkins-pipeline-generator-improved.py via subprocess.run, which no longer exist. Both generators are now called directly via the scaffold_gha and scaffold_jenkins modules (same _run_module_main pattern used by all other scaffold subcommands).

Added

  • Graceful help exit for all scaffold subcommands — invoking any of the 7 scaffold subcommands (gha, jenkins, gitlab, argocd, sre, devcontainer, cicd) with no options now prints the command's full help text (including usage summary and examples) and exits cleanly with code 0, instead of silently running with defaults.
  • --version / -V flag — devopsos --version (or devopsos -V) prints the current version string and exits. Version is sourced from the new cli/__version__.py single source of truth.
  • cli/__version__.py — single source of truth for the package version (0.2.0).
  • CHANGELOG.md — this file, tracking all notable changes.

0.1.0 - 2025-03-08

Added

CLI (cli/)

  • devopsos unified CLI – single entry-point (python -m cli.devopsos) built with Typer.
  • devopsos init – interactive wizard that scaffolds a .devcontainer/devcontainer.json tailored to the languages, CI/CD tools, and DevOps utilities you select.
  • devopsos scaffold gha – generates a multi-stage GitHub Actions workflow (lint → build → test → deploy).
  • devopsos scaffold jenkins – generates a Jenkinsfile with declarative pipeline stages.
  • devopsos scaffold gitlab – generates a .gitlab-ci.yml with Docker, Kubernetes, and deploy stages.
  • devopsos scaffold argocd – generates ArgoCD Application and AppProject manifests for GitOps deployments.
  • devopsos scaffold sre – generates Prometheus alert rules, Grafana dashboard JSON, and SLO manifests.
  • devopsos scaffold devcontainer – standalone devcontainer scaffolder with full tool-version control.
  • devopsos scaffold cicd – meta-scaffolder that runs both GHA and Jenkins generation in one step.
  • devopsos process-first – prints Process-First DevOps principles (Systems Thinking sections: what, mapping, tips, best-practices).
  • --version / -V flag – prints the current devopsos version and exits.

MCP Server (mcp_server/)

  • FastMCP-based server exposing every scaffold function as a native AI tool for Claude / ChatGPT plugins.
  • Tools: generate_github_actions, generate_jenkins_pipeline, generate_gitlab_ci, generate_argocd_config, generate_sre_config, generate_devcontainer, generate_cicd_pipeline.
