🛑 Breaking changes 🛑

  • operator: Remove kube-rbac-proxy from operator deployment and use controller-runtime built-in auth (#3369)
    The operator now uses controller-runtime built-in auth for the metrics server. It is disabled by default.
    The client accessing the metrics endpoint must have the following RBAC rule nonResourceURLs: "/metrics", verbs: get.
    Which didn't change from the previous approach of using kube-rbac-proxy.

    This changes adds following flags to the operator:
    metrics-secure - enables authentication and authorization for the metrics server. If no TLS certificates are provided, self signed certificates will be generated.
    metrics-tls-cert-file - TLS certificate file for the metrics server
    metrics-tls-key-file - TLS private key file for the metrics server

    This change changes the following flags on the operator:
    --metrics-addr - changes from 127.0.0.1:8080 to :8443 which matches the operator's metrics service port.

💡 Enhancements 💡

  • target allocator: Add support for prometheus scrape classes (#3600)
    Added support for configuring scrapeClasses when using the PrometheusCR-feature of the target allocator. The format of the scrapeClasses array is exactly as same as spec.scrapeClasses of the Prometheus CRD.
  • operator: Add support for Kubernetes 1.35 (#4575)
  • collector: exposes the spec.hostPID field for the collector. (#4214)
    This will allow to set the spec.HostPID field for the collector. By default this the field is false.

🧰 Bug fixes 🧰

  • target allocator: Fix CA certificate race condition with client cert renewals by extending its duration and and renewal attempt. (#4441)
    The CA certificate now has a 2-year duration (instead of the default 90 days) to prevent race conditions
    where client and server certificates could be signed by different CA versions during simultaneous renewal.
    This ensures the CA remains stable while dependent certificates renew regularly.

  • collector: Add finalizers to OpenTelemetryCollector CR only when cluster roles and bindings for SA are created by Operator. (#4367)
    Finalizer usage was restricted to cluster scoped resources only. Namespaced resources no longer receive finalizers,
    preventing blocked namespace deletion if the operator is removed first. The change aligns finalizer behavior with
    cluster-level RBAC availability, ensuring finalizers are applied only when the operator has the required
    cluster scoped permissions.

  • config: Fix manager logger initialization (#4584)
    Apply config before setting up logger to configure it properly.

  • operator: Fix the --annotations-filter and --labels-filter CLI flags. (#4594)
