Agenda​

  • DEMO: wit provider nats-messaging from Taylor
  • DISCUSSION: wadm wasmCloud introduction, 0.5.0 roadmap

Meeting Notes​

Status update - moving to WIT​

  • Background; we have a new PR in the wasmCloud/wasmCloud repo around capability provider SDKs for Wasm providers - specifically for generating them with wit IDL interfaces.
  • Visit this interesting PR if you want to see the codegen behind the wasmCloud SDK PR.
  • This focus exemplifies our drive from Smithy to wit.
  • If you'd like to see the example of the provider SDK, you can look at Taylor's repo https://github.com/thomastaylor312/nats-messaging-wit for nats messaging with wit. This is using the new repo for providers. you can take a look and see the messaging contract.
  • Actors can make requests and publish operations.
  • From this wit messaging interface there is a world - we'll cover worlds in future weeks.
  • The real benefit is the new code is really simple - we instantiate a new handler and, for each of the ops you can invoke, there is a trait and the method can be implemented by a specific capability provider.
  • As we move forward, we will look to change wasmCloud 1st party providers.
  • Roman created an issue milestone in the wasmcloud/wasmcloud repo witify. Using all wit contracts for all capability providers and contracts, Roman has outlined a couple of small tasks to get to this milestone.
  • All the functionality of wasi-cloud will be integrated into wasmCloud, and custom contracts will work with wasifills.
  • Watch the recording for a longer discussion on this subject and catch Taylor's demo at the next meeting.

DISCUSSION: wadm wasmCloud introduction, 0.5.0 roadmap​

  • We started cutting alpha for Wadm 0.5. These are new features that are minor breaking changes so we're cutting an early release.
  • Multi-tenant flag fixes. Multi-tenant mode allows a Wadm instance to monitor multiple lattices.
  • There is a wasmCloud in production guide under the wadm section - talks through the process of working with NATS clusters.
  • Couple of issues we'd like to get into 0.5 release candidate:
    • Logic to validate manifests. When we put a manifest together for a new app we should be able to do some validation within Wadm itself.
    • Dynamic status view: status view is static right now - change to allow us to see if our Wadm app is fully-deployed, failed etc.
    • Support version upgrades: you can't set up an app in Wadm then upgrade your version Wadm...yet. Wadm currently does a simple comparison of public keys and requires manual stop. We'd love for Wadm to be able to handle upgrades.
  • Brooks will have a more fulsome demo in the coming weeks.
  • If you're interested in contributing to Wadm we have a couple of issues that are marked as good first issues.

DISCUSSION: Meetups!​
