What was changed?
Cloud CI now creates an isolated Temporal Cloud namespace for each workflow run and attempt. A small test-only Java command uses the SDK's existing Cloud Operations client to create an mTLS namespace, wait for provisioning, and delete it by its current resource version after tests finish.
The Cloud job passes the generated namespace and client certificate to the envconfig-backed harness. It publishes the namespace before waiting for provisioning so cleanup can still run after a partial failure, and namespace deletion runs under
always()whenever creation returned a namespace. Cleanup failures fail the job so leaked resources remain visible.This PR is stacked on #2998 and should be retargeted to
mainafter that harness PR merges.Why?
The SDK test suite needs an isolated Cloud target before it can safely expand beyond a smoke test. Per-run namespaces prevent concurrent CI runs from sharing workflow state and provide an explicit cleanup boundary without relying on long-lived namespace credentials.
Breaking changes?
None. The namespace command and Gradle tasks are internal test infrastructure.
Server PR
None.
How was this tested?
CloudTestNamespaceManagerTesttests covering namespace specifications, deletion resource versions, operation states, polling delays, and required operation IDs.temporal-sdktest task with bounded local workers.actionlint .github/workflows/ci.yml../gradlew spotlessApplyandgit diff --check.The draft PR's Cloud job provides the end-to-end create, envconfig smoke-test, and delete validation.
Operational notes
TEMPORAL_CLIENT_CLOUD_API_KEYmust have account-level permission to create, inspect, and delete namespaces inaws-ca-central-1. Workflow tests authenticate to the ephemeral namespace with the generated mTLS certificate rather than that API key.
