🛑 Breaking changes 🛑

  • operator: change java instrumentation feature gate operator.autoinstrumentation.java into command line flag --enable-java-instrumentation (#2673, #2582)
  • operator: remove featuregate operator.autoinstrumentation.nodejs. Use command line flag --enable-nodejs-instrumentation instead (#2674)
  • operator: remove featuregate operator.autoinstrumentation.go. Use command line flag --enable-go-instrumentation instead (#2675)
  • target allocator: Remove operator.collector.rewritetargetallocator feature flag (#2796)
  • target allocator: Drop compatibility with older target allocator versions (#1907) We've made a breaking change to the target allocator configuration in 0.93.0. This change removes operator compatibility with target allocator versions older than that. Users running more recent target allocator versions are unaffected.

🚀 New components 🚀

  • collector: Enable reconciliation of Collector v1beta1 CRD. See CRD changelog for detailed information. (#2620, #1907) Users are expected to migrate to otelcol.v1beta1.opentelemetry.io. The support for otelcol.v1alpha1.opentelemetry.io will be removed in the future. Follow migration guide for upgrading already created collector instances. After all otelcol.v1alpha1.opentelemetry.io are stored as v1beta1 update the collector CRD to store only v1beta1 kubectl patch customresourcedefinitions opentelemetrycollectors.opentelemetry.io --subresource='status' --type='merge' -p '{"status":{"storedVersions":["v1beta1"]}}'. Only AllNamespaces install mode is now supported due to the conversion webhook from v1beta1 to v1alpha1. See OLM docs and OLM operator groups docs.

💡 Enhancements 💡

  • collector: Changes metric port logic to use intermediary struct. (#2603)
  • collector: Remove collector v1alpha1 defaulting and validating webhooks. (#2736) The functionality was moved to the collector v1beta1 webhooks.

🧰 Bug fixes 🧰

  • auto-instrumentation: Add attribute service.instance.id while pod is mutated. (#2679) service.instance.id is expected to be <namespace>.<podName>.<containerName>

    But while pod is created it may not have the podName yet at the podMutator webhooks.

    This changed to use the env var OTEL_RESOURCE_ATTRIBUTES_POD_NAME which will be present at runtime. <namespace>.$(OTEL_RESOURCE_ATTRIBUTES_POD_NAME).<containerName>

    Making a valid and complete value for service.instance.id to be added.

  • collector: Fixes a bug that would cause errant rollouts on a non-config related change. (#2899)

  • collector: resolves a bug that would create a junk selector for the service by merging rather than overriding. (#2873)

  • target allocator: Fix a metric relabel config unescaping bug (#2867) If only metric relabel configs were present, without target relabel configs, unescaping wouldn't be applied, leading to invalid Target Allocator configuration.

Components

🛑 Breaking changes 🛑

  • operator: change nginx instrumentation feature gate operator.autoinstrumentation.nginx into command line flag --enable-nginx-instrumentation (#2582, #2676)
  • operator: remove featuregate operator.autoinstrumentation.python. Use command line flag --enable-python-instrumentation instead (#2582, #2672)
  • target allocator: Promote operator.collector.rewritetargetallocator feature flag to stable (#2796)

💡 Enhancements 💡

  • auto-instrumentation: Bump NodeJS autoinstrumentations dependency to a version that supports enabling selected instrumentations via environment variable. (#2622) See the documentation for details. Usage example: export OTEL_NODE_ENABLED_INSTRUMENTATIONS="http,nestjs-core".

  • auto-instrumentation: CronJob name propagated to the OTEL Service Name (#2716) When instrumenting a CronJob it would generate a Job and then a Pod. Previously it would use the Job name as the Service name, generating too many different services on each cron execution. This release fixed to collect the Job parent's name, if it has one.

  • instrumentation: Instrumentation now automatically add node and pod ips as env vars OTEL_NODE_IP and OTEL_POD_IP to instrumented containers. (#2769)

  • auto-instrumentation: Remove NodeJS autoinstrumentation dev dependencies to reduce image size (#2802)

  • instrumentation: Remove env var prefix validation (#2768)

🧰 Bug fixes 🧰

  • collector: Fix the RBAC resources creation when the processor was only enabled (#2788)
  • operator: Added missing label for Service/Pod Monitors (#2251)
  • instrumentation: Don't preserve ownership of files copied from the autoinstrumenation image. This avoids issues when instrumenting workloads running as non-root (#2655)
  • opamp bridge: Fix opamp bridge configmap "app.kubernetes.io/version" label to be generated in the same way as other resource version labels (#2583)

Components

0.96.0

🛑 Breaking changes 🛑

💡 Enhancements 💡

  • operator: Created ability to filter out Annotations (#2627)

🧰 Bug fixes 🧰

  • target allocator: Fix per-node target allocation for targets from endpointslices (#2718) The per-node target allocation strategy was not matching endpointslice entries for with a kind of Node, such as those for the kubelet metrics created by the prometheus operator
  • operator: Removes UPDATE from pod mutating admission webhook since it only needs to mutate on pod CREATE events. (#1514) The pod webhook currently modifies the pod spec in invalid ways on UPDATE events, and UPDATES are not necessary in the webhook.

Components

0.95.0

🛑 Breaking changes 🛑

  • The operator now requires CRUD permissions for PersistentVolume and PersistentVolumeClaim. See #2575 for details. The official kustomize manifests and Helm Chart will include this change, otherwise it will need to be applied manually.
  • operator: remove featuregate EnableApacheHTTPAutoInstrumentationSupport. Use command line flag --enable-apache-httpd-instrumentation instead (#2582, #2670)

Components

0.94.0

💡 Enhancements 💡

  • target allocator: Add new "per node" allocation strategy to target allocator. This strategy will allocate targets to nodes on which given target resides. It should only be used conjunction with the daemonset mode. (#1828)

🧰 Bug fixes 🧰

  • operator: Fixed handling of protocol in exposed ports. (#2619) Make distinction not only on the port number, but also on protocol. This fix allows to have multiple exposed ServicePorts with the same port number, but different protocols.

  • operator: Fixed handling of exposed port protocol in syslog, tcplog and udplog receivers. (#767, #2619) Please note that the operator currently exposes just one port (tcp or udp) of syslog receiver due to the current receiver implementation (patches are welcome).

  • operator: Fixing WATCH_NAMESPACE for a single namespace value (#2589)

Components

❌ Breaking Changes ❌

  • Jaeger receiver no longer supports remote sampling. To be able to perform an update, it must be deactivated or replaced by a configuration of the jaegerremotesampling extension. It is important that the jaegerremotesampling extension and the jaegerreceiver do not use the same port. To increase the collector version afterwards, the update must be triggered again by restarting the operator. Alternatively, the OpenTelemetryCollector CRD can be re-created. (otel-contrib#14707)
