## Summary
Every chart-managed Pod now carries a chart-owned
`tags.datadoghq.com/version` label derived from the deployed image,
instead of a value each wrapper restates once per workload.
Covered Pod templates:
- relay Deployment (`templates/deployment.yaml`)
- pairing relay (`templates/pairing-relay.yaml`)
- storage-accounting CronJob
(`templates/storage-accounting-cronjob.yaml`)
- operator jobs, including the deletion drain
(`templates/_operator-jobs.tpl`)
**Source order:** `image.tag`, then `image.digest`, then
`Chart.AppVersion` (`buzz.imageVersionSource`). Tag-first is deliberate:
- The rendered value matches the `sha-<commit>` pins wrappers already
carry, so upgrading to this chart does not roll any Pods.
- An image promotion only has to write `image.tag` + `image.digest`. No
per-workload label edit is needed.
Exact runtime identity stays exact in two places. The image reference is
`repository@digest` when a digest is pinned.
`BUZZ_STORAGE_SNAPSHOT_CODE_SHA` (persisted as `code_sha`) is still
digest-first.
**Label safety:** `buzz.imageVersionLabel` maps any OCI tag or digest to
a valid label value.
- Valid values already in Datadog's normal form (lowercase, no `__`)
pass through byte for byte, so `sha-<hex>` and `1.2.3-rc.4` are
unchanged. Datadog lowercases tag values and collapses `__`, so any
other value is hashed rather than allowed to report the same version as
a different revision.
- A digest keeps 63 hex characters.
- Anything else is replaced by the first 63 hex characters of its
SHA-256.
- Exactly 63 lowercase hex characters is reserved for the hashed and
digest forms, so a rendered label cannot be fed back as a tag to make
two revisions collide.
- When both tag and digest are set, the label names the tag even if they
disagree; the digest still pins what runs.
**Precedence:** a `tags.datadoghq.com/version` supplied through any
workload's `podLabels` is ignored. Every other label, including
`tags.datadoghq.com/env` and `/service`, passes through unchanged.
Overriding instead of failing means a wrapper with a stale pin is
corrected by the upgrade itself. The chart bump and the wrapper cleanup
don't have to land together.
**What got simpler:** one image identity instead of N. Wrappers delete
their per-workload version pins. Image promotion tooling no longer needs
a "mirror the tag into a label path" feature. One shared helper
(`buzz.podLabelsWithVersion`) replaces four `podLabels` passthroughs.
Chart `0.1.10 → 0.1.11`, with an `artifacthub.io/changes` entry.
Documented in the chart README ("Datadog version label") and
`docs/deployment-identity.md`.
Note: a vendor-namespaced label now renders unconditionally in an OSS
chart. This is in tension with
[VISION_SOVEREIGN.md](../blob/main/VISION_SOVEREIGN.md). The label is
inert without the operator-supplied `tags.datadoghq.com/service`/`env`,
and the chart already ships vendor-specific defaults (e.g.
`sidecar.istio.io/inject`).
### Testing
Run on a Blox (Linux) workstation at tree `41634b7ca` (helm v3.16.4,
helm-unittest 0.8.2, the CI versions):
- `helm lint deploy/charts/buzz`: 0 failed
- `helm unittest deploy/charts/buzz`: 12 suites, **85/85 passed**
New `tests/version_label_test.yaml` checks the relay, pairing relay, and
deletion drain: tag wins over a stale `podLabels` pin, the label is
stamped with no `podLabels`, and digest-only images get a label-safe
value. `tests/storage_accounting_test.yaml` covers the same cases for
the CronJob, plus the `Chart.AppVersion` fallback.
Mutation checks:
- Reverting any one template to the plain `podLabels` passthrough fails
tests.
- Switching the source order to digest-first fails tests.
- Restoring the case-insensitive passthrough fails the three
Datadog-normalization tests (uppercase, `__`, uppercased 63-hex).
No Rust, desktop, web, or mobile sources changed.
