Community Calls
WebAssembly Kubernetes Workload Identity with SPIFFE & SPIRE
The April 9, 2025 wasmCloud community call centers on WebAssembly Kubernetes workload identity. Fresh off back-to-back wasm.io Barcelona and KubeCon London, Joonas Bergius demos the work he and Colin presented on stage: using SPIFFE and SPIRE to give WebAssembly workloads a verifiable identity, then exchanging short-lived SPIFFE JWTs for temporary AWS credentials — no static secrets in the mix. Bailey Hayes and Liam Randall co-host, walking through how this solves first- and third-party multi-tenancy and cross-cloud deployment, before a community Q&A on WASI version compatibility, Helm/NATS deployments, and the capability boundaries of the WebAssembly component model.
WasmPay Demo: The Wasm Component Model for Cross-Language Payments
The April 2, 2025 wasmCloud community call streams live from the wasmCloud booth in the CNCF Project Pavilion at KubeCon + CloudNativeCon Europe 2025 in London. Brooks walks through the team's conference schedule — including talks on wasmCloud's road to the standards, SPIFFE workload identity, and WebAssembly on Kubernetes — and then demos WasmPay, a cross-language, cross-country payment processing platform. WasmPay shows the Wasm component model at work: banks supply transaction validators written in any language that compiles to WebAssembly, and wasmCloud composes each untrusted validator with a "platform harness" component that handles HTTP, NATS messaging, and the validation contract.
wasmCloud Q1 Roadmap, WASI Preview 3 & the Wasm Component Model
The March 26, 2025 wasmCloud community call is the last of the quarter, so Brooks Townsend walks the Q1 roadmap end to end — what shipped, what's in flight, and what slipped — with the Wasm component model and WASI Preview 3 dominating where maintainer time went. Open-source benchmarking Helm charts and a combined wash CLI/lib landed; a cron-job provider, logging-buffer error counts, and bundling are in progress; and a big chunk of the team's effort went upstream into Wasmtime and JCO to push WASI P3 across the line. The call closes with a look ahead to WASM I/O Barcelona and KubeCon + CloudNativeCon EU in London.
WebAssembly Composition & the Wasm Component Model in wasmCloud
The March 19, 2025 wasmCloud community call centers on the Wasm component model — both at build time and over the lattice. Brooks Townsend demos how to compose WebAssembly components with the wac plug tool, then shows new wash build functionality (in a PR) that performs the same composition automatically using WAC's Rust library, so developers never have to install or learn the CLI. The call then turns to a community proposal from LUK3ARK: "virtual components," a way for components to route invocations over wRPC to services that live outside the lattice — and the security questions that raises.
wadm Config Reconciliation, the Single wash CLI & KubeCon EU
The March 12, 2025 wasmCloud community call is a tooling-focused update for anyone building on the Wasm component model. Brooks Townsend demos a wadm reconciliation fix that takes local application deploys from around 15 seconds down to under one second by reacting to configuration events instead of waiting for a heartbeat. The team also marks the completion of the long-running merge of wash-cli and wash-lib into a single wash crate, previews wasmCloud's presence at KubeCon EU and WasmIO in Barcelona, and digs into tracing and observability for capability providers.
