containerd with Wasm: mixed workloads in production
containerd Wasm support is production ready: the runwasi shim ships in containerd 2.0 and is backported to 1.7.7 and 1.6.25, so WasmEdge or wasmtime workloads run beside ordinary Linux containers on one Kubernetes cluster, selected per pod through RuntimeClass. Wasm wins on cold start, image size and kernel-free sandboxing, but not every workload fits.
