Agenda​

• DEMO: wadm 0.5 feature showcase
• DISCUSSION: Roadmap update on Rust host and Witify efforts

Meeting Notes​

Wadm 0.5 Feature Showcase​

• Wadm repository - view in issues page - current milestones: v0.5.0, v0.6.0 issue milestone.
• v0.5.0 will be the next release. This will come with a host of new features and fixes.
• None of these developments are tagged good first issues but we think it would be good to open things out to contributions.
• Priorities for v0.5.0
  • Version upgrades for actors and providers.
  • Terminating old resources.
  • Validation around manifests.

DEMO​

• Demo setup: wash up -d --disable-wadm and then running wadm from the manifest upgrade branch.
• Wadm is responsible for managing applications in declarative states.
• In our pet clinic app example you'll see a wadm.yaml - uses the OAM format - using the same standard.
• In this example, we see 5 different actors laid out as components inc. image ref. and assembled spread scaler trait (allowing you to spread out to more locations - more to come on that!).
• New feature: Status Updates - allows you to see whether your app fully-deployed, if it's having issues finding available hosts, etc.
• New feature and fix: manifest upgrades - deploy a new version of an application that has changes. You can update the version in the manifest - and run several replicas of the same instance.
• In this example, we see the manifest update across 5 separate actors.
• See the recording for the full demo and discussion.

DISCUSSION: Roadmap update on Rust host and Witify efforts​

• Following the publication of the wasmCloud Roadmap, we're keen to make sure you're updated on how we're integrating WASI Standards and priming wasmCloud for the Component Model.
• Community members have been working on the Rust host - most of the core functionality will be in within the next few weeks.
• WITify - the effort to change all interfaces to WIT and expressing our logics in actors and providers, based on WIT. We have made great progress here -- Victor has been been scaffolding it out, getting codegen working for providers.
• Wasifills, multiplexer experiments. Paused whilst some changes within the Wasm community have been ratified.
• If anyone has any suggestions around the roadmap and issues milestones, feel free to suggest.

Community Updates​

Wasm Ecosystem​

• Take a look at Golang site Go 0.21, now released with an experimental port for WASI - really exciting development in the Go space.
• The Bytecode Alliance already organized a Go subgroup in its SIG Guest Languages.
