Meeting Notes​

New Community Member - Dave Tessman 👋 Hi, Dave!​

Discussion - wadm 0.5.0 official release, wash 0.20.0 coming soon​

  • Many alphas for wadm means lots of testing and lots of new features: manifest status, manifest validation, multitenant prefixes.
  • What is Wadm? Tool to assist with deploying applications in a declarative manner.
  • Demo - wadm 0.5.0 manifest validation.
  • validation built on top of OAM spec.
  • define components as custom types.
  • specify links values and spreadscaler conditions with custom traits on components.
  • The Demo:
    • valid demo: kvcounter app should access redis and use http server.
    • invalid dupe actor: duplicate actor with same image ref. Prefer not to run multiple components, use spread to control distribution.
    • invalid link manifest: two versions of the same link results in a validation error because they provide conflicting values.
    • invalid dupe provider: two components with the same provider component names, prefer spread scaler.
    • invalid duplicate link name: two providers with the same contract and link name, links can be used to configure providers.

Discussion - Roadmap​

  • Deamonscaler: adds ability to scale a component (actor/provider) to run X copies on every host that matches the label spec.
  • WASI Preview 2 components is in progress.
  • witify - changing interfaces to use wit IDL - only a few issues to complete.
  • OTP/Rust Host feature parity - more closed than open, lots and lots of progress (s/o to Roman and Connor and Victor).
  • New contributors can help out with good-first-issue label on wash, wasmCloud, wadm repos.
