Hey folks 👋

We just updated our Temporal + Kubernetes testing tutorial with a TypeScript worker example. It shows how to get high-fidelity, pre-merge testing of a single worker change against your live Kubernetes cluster without duplicating the stack.

Fun gotcha we hit: TS workflow code runs in a V8 isolate, so you can't do the routing-cache lookup inside the interceptor like you can in Python. Ended up delegating the check to a local activity on the node side.

If you're running Temporal workers in k8s and want to test new versions without redeploying the whole stack, it might be useful: signadot.com/blog/how-to-test-temporal-services-using-signadot-sandboxes

We’re happy to answer questions.
