Compute

Run a compute-intensive WASM task via the Kubernetes operator

This example runs the CPU-intensive compute WASM module through the Propeller Kubernetes operator. It performs an O(n⁵) calculation inside five nested loops.

Prerequisites

The operator must be deployed and a Proplet registered. Follow the end-to-end example first if you have not done that.

Build the WASM Module

cd propeller
make compute

Apply the Task

WASM_B64=$(base64 -w0 propeller/build/compute.wasm)
kubectl apply -n propeller-workloads -f - <<EOF
apiVersion: propeller.propeller.absmach.eu/v1
kind: Task
metadata:
  name: compute-example
spec:
  name: compute-example
  functionName: compute
  file: "${WASM_B64}"
  inputs:
    - "50"
  propletSelector:
    propletId: "k8s-proplet"
EOF

Watch and Verify

kubectl get task compute-example -n propeller-workloads -w

Wait for the phase to become completed:

kubectl get task compute-example -n propeller-workloads \
  -o jsonpath='{.status.results}'

Expected result: 1377515305
