Ruby apps gain out-of-box tracing in Dash0 Operator

The Dash0 Operator for Kubernetes v1.151.0 introduces automatic instrumentation support for Ruby 3.3+. Ruby applications can now get auto-instrumentation with the operator injecting the Dash0 OpenTelemetry Ruby distribution at container startup. Rails apps, Bundler-managed services, and plain Ruby scripts all gain distributed tracing out of the box.

Monitoring activates for apps running on Ruby 3.3 or later. Workloads running older runtimes are unaffected — the distribution detects the version at startup and deactivates itself gracefully. Ruby monitoring is opt-in and off by default.

To enable it, upgrade to v1.151.0 and set operator.instrumentation.enableRubyAutoInstrumentation=true when installing or upgrading the Helm chart.
