Zero to Published: Building an Automated Release Pipeline with GitHub Actions, Mise, and DevPod

Description and use

An automated release pipeline for a Python monorepo project using DevPod, Mise, Ruff, Pytest, and GitHub Actions that builds, tests, and publishes a release on tag creation.

Problem

Manual releases are slow, error‑prone, and hard to reproduce, leading to missing files or dependency mismatches.

Outcome

Automated pipeline reduces release errors, ensures reproducibility, and speeds up delivery from code to GitHub Release.

Workflow

• Set up DevPod container with Mise for deterministic dev environments
• Declare tool versions in mise.toml and install via mise install
• Run local quality gates: mise exec -- ruff check . and mise exec -- pytest
• Create GitHub Actions workflow that triggers on tag push
• Checkout repo, set up Mise, install dependencies
• Run lint and test gates; halt on failure
• Build release archive dist/automated-release-pipeline.tar.gz
• Upload artifact with actions/upload-artifact
• Publish GitHub Release with softprops/action-gh-release and attach tarball

Evidence

Manual releases are slow, error‑prone, and painful to reproduce.
