Full Changelog: v0.0.24...v0.1.0

Breaking change since v0.1.0-rc.0

The two ServiceMonitor value groups are merged into one:

• metrics.serviceMonitor.* and cloudflaredServiceMonitor.* are replaced by a single serviceMonitor group.
• One serviceMonitor.create switch now creates ServiceMonitors for both the controller and the managed cloudflared connectors.
• Connector only settings moved under serviceMonitor.cloudflared (jobLabel, honorLabels, scheme).

Migration example:

# before
metrics:
  serviceMonitor:
    create: true
cloudflaredServiceMonitor:
  create: true
  jobLabel: app.kubernetes.io/component

# after
serviceMonitor:
  create: true
  cloudflared:
    jobLabel: app.kubernetes.io/component

Grafana dashboards

• Dashboards are now published on grafana.com: 25659 (controller) and 25660 (per hostname traffic), and the dist JSON files pass the grafana.com upload check.
• Traffic dashboard: latency percentiles (p50/p90/p95/p99), request duration heatmap, stacked bar charts for request rate and status classes, in/out traffic volume, and a new pod variable to filter by connector pod.
• Controller dashboard: the job variable no longer matches unrelated jobs when set to All, and the sync freshness stat stays green.

See the monitoring guide for setup.

Full Changelog: v0.0.22...v0.0.23

• feat: add --cluster-domain flag for custom cluster domains

Kubernetes clusters can use a custom domain via --cluster-domain
(kubelet) instead of the default cluster.local. The controller
hardcoded cluster.local when constructing backend service FQDNs,
causing DNS resolution failures on clusters with custom domains.

Add a --cluster-domain flag (default: cluster.local) and expose
it as a Helm value (clusterDomain).

Fixes #263

• test: use custom cluster domain in tests to verify --cluster-domain flag

Use non-default cluster domains across unit, integration, and e2e tests
to ensure the clusterDomain parameter is actually propagated rather than
relying on the default "cluster.local". Also enrich descriptions for the
--cluster-domain flag and the Helm clusterDomain value.
