0.158.0

💡 Enhancements 💡

  • operator, collector, target allocator: Enable operator, collector, target allocator network policies by default. (#5394)
    Feature gate operator.networkpolicy and operand.networkpolicy are promoted to beta, and enabled by default.
    These feature gates create network policies for the operator and operand components.

  • auto-instrumentation: Apache and nginx instrumentations forward Spec env vars to attach init containers so kubelet can expand $(VAR) references in exporter endpoints. (#5333)

  • collector: promote the operator.collector.usedefaulttelemetryshape feature gate to stable, so the operator-injected Prometheus telemetry reader always uses collector defaults for without_type_suffix, without_units, and without_scope_info (#5075)
    The gate is now stable and can no longer be disabled. Users wanting the
    pre-v0.154.0 metric name shape should explicitly set
    without_type_suffix, without_units, and without_scope_info to false
    in their collector configuration. The gate will be removed in a future release.

  • collector: moves operator.golang.flags to stable setting GOMEMLIMIT and GOMAXPROCS automatically (#5455)

🧰 Bug fixes 🧰

  • collector: Fix the automatic-upgrade routine binding two Prometheus readers to the same port when a collector already uses service.telemetry.metrics.readers. (#5416)
    When an OpenTelemetryCollector already configured service.telemetry.metrics.readers
    (added by earlier defaulting), the automatic version-upgrade routine still backfilled the
    older, deprecated address field for it. The 0.122.0 upgrade step then migrated address
    into a new reader, leaving two readers bound to the same host:port. The collector then
    failed to start with "address already in use". The 0.111.0 step now skips backfilling
    address when readers is already configured, and the 0.122.0 step now skips adding a
    reader for address if an equivalent one already exists.
  • collector: Add PersistentVolume and PersistentVolumeClaim RBAC rules for k8s_cluster receiver automatic RBAC generation. (#5421)
  • auto-instrumentation: Default OTEL_METRICS_EXPORTER to otlp for Node.js auto-instrumentation so metrics are exported without extra configuration. (#3768)
    The Node.js SDK only initializes its metrics pipeline when a metric reader is configured, and the
    webhook was not setting one. As a result, metrics silently stopped being exported for anyone relying
    on the previous default behavior. The webhook now sets OTEL_METRICS_EXPORTER=otlp by default,
    matching the existing behavior for Python auto-instrumentation, unless the user already set it.
