Real-World Example: Complete Build→Test→Deploy→Release Flow

This example traces a single nodejs-demo-app commit through a complete CI/CD flow, showing exact OTEL spans and CDEvents at each stage.

Scenario

  • Application: nodejs-demo-app
  • Git Event: Push to main branch at 2025-08-06T14:32:00Z
  • Git SHA: abc123def456789 (first 12 chars: abc123def456)
  • App Namespace: app-demo-cicd
  • Image Repo: ghcr.io/myorg/nodejs-demo-app

Generated IDs (at Build Start)

# These are generated by otel_flow_root_begin() and never change for the entire flow:

TRACE_ID="7f2e4a8c1d6b5f3e2c9a4d8f1b6e3a7c"
FLOW_ROOT_SPAN_ID="4c9e2a7d1f3b8e5c"
CHAIN_ID="c4b8e2f5-7d1a-4c9f-b3e6-2a8d5f1c9e4b"
FLOW_START_TIME="2025-08-06T14:32:00.000000000Z"

# Traceparent format (W3C):
TRACEPARENT="00-7f2e4a8c1d6b5f3e2c9a4d8f1b6e3a7c-4c9e2a7d1f3b8e5c-01"

BUILD Stage

Build PipelineRun Creation

apiVersion: tekton.dev/v1
kind: PipelineRun
metadata:
  name: build-nodejs-demo-app-8xk2j
  namespace: app-demo-cicd
spec:
  pipelineRef:
    resolver: cluster
    params:

Task: start-flow-root-span

Step 1: generate-chain-id

printf '%s' "$(uuidgen)" > /tekton/results/chain-id
# Result: c4b8e2f5-7d1a-4c9f-b3e6-2a8d5f1c9e4b

Step 2: start-span (otel-flow-root-start StepAction)

# Executes:
otel_flow_root_begin

# Outputs:

Task: build-image

Step 1: resolve-build-config

# Resolves from config

SPAN_START_TIME="2025-08-06T14:32:06.234567890Z"

Step 2: build-and-push-arm64 / build-and-push-amd64

# Two kaniko runs, one per arch (no bash/otel-cli available in either) - kaniko has no
# multi-arch/manifest-list capability of its own, so each push goes to its own
# throwaway -arm64/-amd64-suffixed tag:
# ghcr.io/myorg/nodejs-demo-app:abc123def456-arm64
# ghcr.io/myorg/nodejs-demo-app:abc123def456-amd64

Step 3: publish-multiarch-manifest

# crane combines the two arch-suffixed images above into one real OCI image index
# under the actual (unsuffixed) tag: ghcr.io/myorg/nodejs-demo-app:abc123def456
# Writes image-digest to /tekton/results/image-digest
# Result: sha256:abc123def456789abcdef123456789abcdef (the INDEX digest, not either
# single-arch image's own digest)

Key Invariants Verified

✅ Trace ID is constant across all stages

  • Flow-root: 7f2e4a8c1d6b5f3e2c9a4d8f1b6e3a7c
  • Build stage: 7f2e4a8c1d6b5f3e2c9a4d8f1b6e3a7c (same)
  • Test stage: 7f2e4a8c1d6b5f3e2c9a4d8f1b6e3a7c (same)
  • Deploy stage: 7f2e4a8c1d6b5f3e2c9a4d8f1b6e3a7c (same)

✅ Chain ID is constant

  • Generated at build start: c4b8e2f5-7d1a-4c9f-b3e6-2a8d5f1c9e4b
  • Carried through all CDEvents
  • Never changes

✅ Flow start time is constant

  • Set at build: 2025-08-06T14:32:00.000000000Z
  • Carried through all CDEvents
  • Used for flow duration calculation: 14:32:00 → 14:34:42 = 162 seconds

✅ PipelineRun naming is deterministic

  • build-
  • test-<hash(build-event-id)>[0:20]
  • deploy-<hash(test-event-id)>[0:20]

✅ Stage spans are siblings

  • All parent to flow-root (4c9e2a7d1f3b8e5c)
  • Build stage: parent=4c9e2a7d1f3b8e5c, span=9f2d7a3e1c8b5f4e
  • Test stage: parent=4c9e2a7d1f3b8e5c, span=e7b4f2d8c1a5e9f3
  • Deploy stage: parent=4c9e2a7d1f3b8e5c, span=d9c5e1f8a2b7f3e6

✅ Task spans nest correctly under stage spans

  • build-image: parent=9f2d7a3e1c8b5f4e (build stage)
  • clone-repo: parent=e7b4f2d8c1a5e9f3 (test stage)
  • run-tests: parent=e7b4f2d8c1a5e9f3 (test stage)
  • deploy: parent=d9c5e1f8a2b7f3e6 (deploy stage)
