fix: propagate claim UID label to Pods - #1423
kubernetes-prow[bot] merged 1 commit into
Conversation
The SandboxClaim controller records the Claim UID on Sandbox metadata, but the core controller filters the PodTemplate copy and did not restore the trusted metadata value. Propagate the label only from SandboxClaim-owned Sandboxes. Keep reserved-label filtering intact and cover new and existing Pod reconciliation.

Pull request overview
This PR fixes a label-propagation gap in the core Sandbox controller so the agents.x-k8s.io/claim-uid label (set by the SandboxClaim controller on Sandbox metadata) is explicitly copied onto backing Pods, while still blocking tenant-supplied values from the PodTemplate.
Changes:
- Propagate
agents.x-k8s.io/claim-uidfromSandbox.metadata.labelsto Pods only when the Sandbox is controller-owned by aSandboxClaim. - Include the claim UID label in the extension-label reconciliation set so it is added/removed on existing Pods as ownership/expectations change.
- Add regression tests covering both new Pod creation and existing Pod reconciliation.

Hi @janetkuo - Saw that you added the copilot label. I replied to the copilot comment. I don't think any code change is required. The propagation also follows the existing extension-owned metadata pattern used for warm-pool-sandbox and sandbox-template-ref-hash. Let me know what do you think. Thanks! |

nit: add a helper to factor out this map initialization and label setup block (which is repeated 3 times now)

Apologies for missing this, the PR got automatically merged - will raise a followup to address this

No worries, I applied lgtm given that this isn't a blocker and can be addressed in a follow up

…claim UID label PR kubernetes-sigs#1423 added two TestReconcilePod cases that assumed the pod-name annotation is still written to the Sandbox. Since this branch removes that write, update wantSandboxAnnotations on both to expect none.
* remove podname label from type and sandbox controller * Remove pod name annotation usage in controllers and tests Since Sandbox WarmPools now create full Sandbox CRs instead of bare pods, pod names always match sandbox names. This removes setting and resolving the pod name annotation in extension controllers, cleans up obsolete adoption tests across controllers and e2e suites, and updates examples to use Sandbox names directly. TAG=agy CONV=8bd5a682-fc96-4fa2-a380-93979f66daab * Remove PodNameAnnotation from Go SDK and docs Since Pod names now always match Sandbox names, the PodNameAnnotation constant is removed from the Go SDK types and documentation, and state extraction in k8s.go resolves PodName directly to SandboxName. TAG=agy CONV=8bd5a682-fc96-4fa2-a380-93979f66daab * Remove POD_NAME_ANNOTATION from Python SDK and RL examples Since pod names always match sandbox IDs, get_pod_name() now returns sandbox_id directly without querying Kubernetes annotations. This removes POD_NAME_ANNOTATION constants across the Python SDK and agent-sandbox-rl example. TAG=agy CONV=8bd5a682-fc96-4fa2-a380-93979f66daab * Update docs, scripts, and examples to remove pod-name annotation lookups Since Sandbox pod names are now identical to Sandbox names, documentation, quickstarts, and e2e test scripts no longer query the agents.x-k8s.io/pod-name annotation and instead use Sandbox names directly. TAG=agy CONV=8bd5a682-fc96-4fa2-a380-93979f66daab * Update quickstart guides to wait on SandboxClaim and resolve adopted Sandbox TAG=agy CONV=8bd5a682-fc96-4fa2-a380-93979f66daab * Remove unused get_sandbox mock in test_sandboxclient TAG=agy CONV=8bd5a682-fc96-4fa2-a380-93979f66daab * Fix e2e test imports and format test files TAG=agy CONV=8bd5a682-fc96-4fa2-a380-93979f66daab * Clean up redundant pod name tests in Go and Python SDKs - Remove redundant test_get_pod_name_caching in Python SDK - Update Go SDK test to TestOpen_PodNameMatchesSandboxName to explicitly test pod name matching sandbox name TAG=agy CONV=8bd5a682-fc96-4fa2-a380-93979f66daab * Remove redundant TestOpen_PodNameMatchesSandboxName in Go SDK TAG=agy CONV=8bd5a682-fc96-4fa2-a380-93979f66daab * Update get_pod_name docstrings in Python SDK TAG=agy CONV=8bd5a682-fc96-4fa2-a380-93979f66daab * revert podname annotation deletions to support backwards compatability * revert clearPodNameAnnotation and annotation pod name lookup deletions for backwards compatibility * update generated go docs * revert unnecessary deletions * add podname annotation write regression guard * lint files, fix typo, and adjust sandbox controller test verifications for new behavior * revert Deprecation prefix podnameannotation var name change * adjust comments * adjust comments for clarity, modify testcase to test new podname annotation behavior * regenerate docs * fix comment typo * fix(sandbox): update TestReconcilePod cases for #1423 claim UID label PR #1423 added two TestReconcilePod cases that assumed the pod-name annotation is still written to the Sandbox.

What this PR does / why we need it:
The SandboxClaim controller writes
agents.x-k8s.io/claim-uidto Sandbox metadata and the PodTemplate. The core Sandbox controller blocks the PodTemplate copy as a reserved label. Its trusted extension-label path restoreswarm-pool-sandboxandsandbox-template-ref-hash, but notclaim-uid.This change copies a non-empty
claim-uidfrom Sandbox metadata only when a SandboxClaim controls the Sandbox. It covers new Pods and existing Pods after warm adoption. Tenant values supplied through the PodTemplate remain blocked.This uses the same ownership check and metadata path as the
sandbox-template-ref-hashfix in #1067.Which issue(s) this PR is related to:
