Michael #1: Dokku

  • An open source PAAS alternative to Heroku.
  • Dokku helps you build and manage the lifecycle of applications from building to scaling.

  • Once it's set up on a host, you can push Heroku-compatible applications to it via Git.

  • Useful things
    • pyupgrade can automatically upgrade code base
      • (However, I frequently just upgrade and run tests and let my old code be as-is until it bugs me. - Brian)
    • black checks pyproject.toml requires-python setting and uses version specific rules.
  • Versions (way more highlights listed in the article)
    • 3.8
      • Assignment expressions := walrus
