Community Calls
wasmCloud v2 RC5: wash new, the Wasm Component Model & Agentic AI
The December 17, 2025 wasmCloud community call is a short, focused look at wasmCloud v2 Release Candidate 5 and the developer experience for building Wasm component model projects. Eric Gregory walks through how wash new has been refactored — the old interactive templating wizard is gone, replaced by cloning an example repo directly from a Git URL — and demos the updated Rust hello world that now uses the wstd standard library for Wasm components. Liam Randall closes with the news that the Linux Foundation has launched an Agentic AI Foundation, with Anthropic donating the Model Context Protocol (MCP).
WebAssembly on Kubernetes: Volume Mounts, Services & HTTP Ingress
The December 10, 2025 wasmCloud community call is all about running WebAssembly on Kubernetes in production. Eric Gregory walks through a new doc and demo for mounting Kubernetes volumes into a Rust component in wasmCloud v2, then shares a fresh overview of workload services as the stateful companions to stateless components. Lucas Fontes lays out the project's biggest remaining deficiency — HTTP ingress across many hosts — and proposes an intelligent ingress gateway that routes by ephemeral workload ID for zero-downtime deployments, all without tying wasmCloud to Kubernetes.
wasmCloud v2 Services, the Wasm Component Model & WASI P3
The December 3, 2025 wasmCloud community call digs into how the Wasm component model shapes wasmCloud v2, where a workload is composed of stateless components plus a new stateful primitive called a service. Lucas Fontes demos a service that opens TCP sockets and acts as localhost for the components in a workload — ideal for connection pooling, proxying, and persistent state — and the team explains how it leans on cooperative threads coming in WASI P3. The call also covers the move of WASI to a monorepo, the rename of the wasmCloud operator to the wadm operator, the C++ challenges behind compiling protobuf to WebAssembly, and the progress of the wasi-tls proposal.
C++ Wasm Components, gRPC & the Wasm Component Model in wasmCloud v2
The November 26, 2025 wasmCloud community call is a hands-on tour of the Wasm component model maturing across the C/C++ toolchain and into wasmCloud v2. Bailey Hayes demos a Bytecode Alliance example that builds a 67 KB WebAssembly HTTP server using modern, ergonomic C++ bindings on wasi:http, walks through how cooperative threads and exception handling are landing in wasi-libc, and shows protobuf compiling out of the box. The call closes with how gRPC rides over a protocol-agnostic wasi:http, plus a deep discussion of how workload identity works in wasmCloud v2 on Kubernetes — replacing v1's identity delegation with a unique workload ID assigned at scheduling time.
WebAssembly on Kubernetes: v2 Helm Operator, wash HTTP & WASI P3
The November 19, 2025 wasmCloud community call is a deep dive into running WebAssembly on Kubernetes with the new wasmCloud v2 runtime. Eric Gregory demos a fresh end-to-end install of the v2.0 release-candidate Kubernetes operator using Helm and kind, then Lucas Fontes walks through a major rework of HTTP in the wash runtime that pulls HTTP, gRPC, and HTTP/2 handling close to the runtime instead of routing it over the network. Bailey Hayes closes with the road to WASI P3 — why P3 components will align on Wasmtime 40 in December — and the group untangles how wasmCloud actually relates to Kubernetes, wRPC, and the schedulers that place workloads.
