Attestation

The Rekor UUID for this release is dc902afe30f02cc9a6847faff1a30920c735b69de8efc5cfafab69eab1a1e8d2

Obtain the attestation:

REKOR_UUID=dc902afe30f02cc9a6847faff1a30920c735b69de8efc5cfafab69eab1a1e8d2
rekor-cli get --uuid $REKOR_UUID --format json | jq -r .Attestation | jq .

Verify that all container images in the attestation are in the release file:

RELEASE_FILE=https://infra.tekton.dev/tekton-releases/pipeline/previous/v1.12.1/release.yaml
REKOR_UUID=dc902afe30f02cc9a6847faff1a30920c735b69de8efc5cfafab69eab1a1e8d2

# Obtains the list of images with sha from the attestation
REKOR_ATTESTATION_IMAGES=$(rekor-cli get --uuid "$REKOR_UUID" --format json | jq -r .Attestation | jq -r '.subject[]|.name + ":v1.12.1@sha256:" + .digest.sha256')

# Download the release file
curl -L "$RELEASE_FILE" > release.yaml

# For each image in the attestation, match it to the release file
for image in $REKOR_ATTESTATION_IMAGES; do
  printf $image; grep -q $image release.yaml && echo " ===> ok" || echo " ===> no match";
done

Changes

Features

Fixes

• :bug: [cherry-pick: release-v1.12.x] fix(resolvers): Allow ResolutionRequests to resolve all Tekton kinds (#10252)

efore this change, ResolutionRequests could only resolve Pipelines, Tasks, and StepActions. After this change, ResolutionRequests can resolve PipelineRuns, Pipelines, TaskRuns, Tasks, Runs, CustomRuns, and StepActions.

• :bug: [cherry-pick: release-v1.12.x] fix: TaskRun stuck in Running when init container is OOMKilled with enableKubernetesSidecar (#10186)

ix: TaskRun no longer gets stuck in Running when an init container (e.g. prepare) is OOMKilled while enableKubernetesSidecar is enabled. The TaskRun is now correctly marked as Failed immediately.

• :bug: [cherry-pick: release-v1.12.x] Fix cross-arch platform command lookup in entrypoint (#10164)

ix entrypoint command lookup when controller and worker nodes run on different CPU architectures (e.g., ARM controller with AMD64 workloads). The controller's CPU variant was leaking into TEKTON_PLATFORM_COMMANDS keys via platforms.NewPlatform(), causing "could not find command for platform" errors on worker nodes of a different architecture.

• :bug: [cherry-pick: release-v1.12.x] fix: truncate affinity assistant volume names to 63 characters (#10137)

ffinity assistant StatefulSet no longer fails when workspace volumeClaimTemplate names exceed 63 characters. Long volume names are now automatically truncated with a hash suffix to stay within the Kubernetes limit.

• :bug: [cherry-pick: release-v1.12.x] fix(pipelinerun): use generateName for anonymous pipeline label (#10079)

Previously, TaskRuns' tekton.dev/pipeline label for anonymous Pipelines would use their PipelineRun's name in their tekton.dev/pipeline label and pipeline metrics tag. After this change, TaskRun and PipelineRun which are created from anonymous Pipelines now reference a sanitized metadata.generateName, when present, for the label tekton.dev/pipeline. Similarly, these TaskRruns and PipelineRuns will populate their respective metrics' pipeline tag with the sanitized generateName instead of using anonymous.

• :bug: [release-v1.12.x] Fix gen-crd-api-reference-docs require to use fetchable version (#10001)

ix gen-crd-api-reference-docs go.mod require to use a fetchable upstream version, fixing module resolution failures for downstream consumers.

• :bug: [cherry-pick: release-v1.12.x] fix(resolvers): validate data is Tekton object in resolver framework (#9963)

Fixes a bug which lets Tekton Resolvers resolve non-tekton objects and arbitrary data. After this change, resolving a non-tekton object causes the ResolutionRequest to fail.
Action Required: Tekton Resolvers are now only permitted to resolve StepActions, Tasks, and Pipelines. Custom resolvers or ResolutionRequest which use the Resolver API for other object types will no longer function.

• :bug: [release-v1.12.x] fix: replace symlinks with subpath params and fix Rekor UUID in release pipeline (#10216)
• :bug: [cherry-pick: release-v1.12.x] Fix PipelineRun premature failure when TaskRun recovers after pod eviction (#10161)
