The chart's agent.image.repository defaulted to ghcr.io/rcourtman/pulse-agent,
an image that has never been published. publish-docker.yml only pushes
rcourtman/pulse; the Dockerfile defines an agent_runtime stage that
*could* be published but it isn't, and commit da7969fb4 from earlier in
this session removed the corresponding pulse-agent attestation
expectations — a clear signal the separate agent image was intentionally
dropped without updating the chart. Customers running
`helm install pulse pulse/pulse --set agent.enabled=true` were silently
hitting ImagePullBackOff on the agent DaemonSet.
Route the chart through the main rcourtman/pulse image instead. To make
that work without per-arch chart overrides, the runtime stage in the
Dockerfile now creates an arch-resolved /usr/local/bin/pulse-agent
symlink to the right /opt/pulse/bin/pulse-agent-linux-{amd64,arm64,armv7}
binary. The chart's agent.command default is /usr/local/bin/pulse-agent,
which overrides the server ENTRYPOINT and runs the pod as a unified
agent on whichever arch the node provides. agent.yaml renders the
command via toYaml so list values pass through cleanly.
KUBERNETES.md's DaemonSet example switches from the arch-hardcoded
/opt/pulse/bin/pulse-agent-linux-amd64 to the new arch-resolved path,
restoring multi-arch portability of the docs example.
validate-release.sh asserts the symlink exists, points at one of the
three supported Linux arch binaries, and is executable in the published
image. A new TestHelmAgentRuntimePointsAtRealImage pins the chart
defaults, the template wiring, the Dockerfile symlink, and the
validate-release.sh guard so the regression class can't quietly
resurface.
Governance: extend the helm-chart-release-runtime verification policy's
exact_files to include scripts/installtests/build_release_assets_test.go
(matching its existing pin set for related deployment-installability
policies); update the subsystem_lookup_test.py fixture that pins the
exact_files list; document the agent-image and pulse-agent symlink
contract in deployment-installability.md Extension Point 7.
Verified locally: `helm lint` passes; `helm template --set agent.enabled=true`
renders a DaemonSet with image rcourtman/pulse:6.0.0,
command ["/usr/local/bin/pulse-agent"], args ["--enable-docker", "--enable-host=false"].
End-to-end image build + agent DaemonSet smoke will run via helm_smoke
on the next release once rcourtman/pulse:6.0.0 is published.
