Developer workshop

Your outcome is an application responding on a Brewlet-enabled cluster, without cluster-admin or runtime-source approval in your normal application workflow. Obtain the platform handoff first.

Package explicit inputs

Build the program/dependencies using your normal toolchain. Choose a language recipe, author launch.json with the provided executable path and declare the supported platforms. Package only app and dependency bytes under /app.

Package with brewlet build as described in the publishing guide, then run brewlet inspect to check the resulting launch descriptor, layers and digest. Do not infer platform support from a language name or depend on a runtime image entrypoint script.

Publish and deploy separately

Publish with brewlet push under the supplied registry policy, then update a reviewed native Deployment manifest with the immutable application digest, approved ID, RuntimeClass, architecture constraints, resources, probes and any explicit volumes. Apply that manifest through kubectl or your normal GitOps process.

Producer credentials, kubelet pull credentials and runtime-source access are different. Do not place registry secrets in application layers.

Verify and make a change

Observe rollout completion and actual HTTP behavior, not just a successful apply. Ask the platform team for brewlet k8s runtime status output, or run it yourself if you can read RuntimeImages, to see the actual runtime binding. Use an absolute Exec command when the runtime has no shell.

Change the application, republish to a new digest and perform a normal workload rollout. For a shared dependency update, use the layer-set workflow. A platform runtime rotation can leave the app digest unchanged; it still does not transplant a live process.

End the session

Remove only the workshop's application resources through their owning workflow. Have the platform finish profile/host cleanup if infrastructure is also being removed. Do not delete cluster-wide inventory or finalizers as an application cleanup shortcut.
