• Fix numerical port behavior
  • This removes the limitation introduced in v0.4.0. Specifying a numerical port in a PodMonitoring will always work again but the container target label is only available when referencing named ports. This is also better aligned with Kubernetes' pod port semantics, where only named ports can unambiguously be resolved to a specific container.
• Rule-evaluator readiness check no longer expects successfully calling the GMP query API.
• Support specifying a generator URL via OperatorConfig and rule-evaluator flag to be sent with alerts.
• Update the Prometheus UI version in the frontend binary.
• external_labels now take precedence over the --export.label.* flag values.
• Accept extra args via the EXTRA_ARGS environment variable. This allows significantly easier usage with prometheus-operator.
• Use port 443 for webhook (operator) service
• Use port 10250 for admission webhooks

Users who deploy managed collection using kubectl should reapply the manifests in the documentation. Users who deploy the service using gcloud or the GKE UI will be automatically upgraded within a week or so. This release has no impact on self-deployed collection users.

A new GMP Prometheus binary depending on this version was made available as version v2.35.0-gmp.2 (container image: gke.gcr.io/prometheus-engine/prometheus:v2.35.0-gmp.2-gke.0).
