Coralogix's OpenTelemetry Integration Helm chart offers a way to enable auto-instrumentation without installing the CRD, using pod annotations like inject-java, inject-python, inject-dotnet, inject-nodejs, and inject-sdk to trigger SDK injection directly through native Kubernetes manifests. Troubleshooting guidance covers missing pod-level annotations, network/egress restrictions, API key/endpoint mismatches, unsupported runtimes, double-instrumentation conflicts, init container crashes from glibc/distroless mismatches, and webhook conflicts when a standalone Operator is also installed. ## Full article daily.dev links to this article rather than hosting it.

You can bypass the Instrumentation CRD entirely by enabling the opentelemetry-autoinstrumentation option in the Coralogix OpenTelemetry Integration Helm chart, which starts an OpenTelemetry Operator instance without installing the CRDs. Pod annotations like instrumentation.opentelemetry.io/inject-java then trigger init container injection directly from Helm-configured global settings, avoiding separate custom resource management. _daily.dev surfaces practical Kubernetes observability setups like this for engineers wiring up OpenTelemetry pipelines._ ### Why isn't my pod getting instrumented even though I added the OpenTelemetry inject-java annotation to my Deployment? The annotation must be present on the pod template metadata, not just the top-level Deployment metadata, or the mutating admission webhook will ignore it. Run kubectl get pod -o yaml to verify placement. Other causes include unsupported runtimes, disabled language flags in the Operator config, or a conflicting standalone Operator webhook fighting over the same pod creation events. _developers debugging auto-instrumentation gaps in Kubernetes can find similar troubleshooting notes on daily.dev._ ### What is the difference between inject-nodejs and inject-sdk annotations in the OpenTelemetry Operator? inject-nodejs and similar language-specific annotations add an init container that copies OpenTelemetry binaries or libraries into the pod, while inject-sdk skips that step and only injects base OpenTelemetry SDK environment variables such as OTLP endpoints and headers. Use inject-sdk when the application already has the SDK manually configured, to avoid double-instrumentation conflicts or duplicate spans. _teams choosing between instrumentation approaches can track these OpenTelemetry patterns on daily.dev._ ## Similar posts on daily.dev - [How to use auto-instrumentation with OpenTelemetry](https://daily.dev/posts/how-to-use-auto-instrumentation-with-opentelemetry-oji0ioxgp) · Red Hat Developer · 0 upvotes · 0 comments - [Instrument zero‑code observability for LLMs and agents on Kubernetes](https://daily.dev/posts/instrument-zero-code-observability-for-llms-and-agents-on-kubernetes-oatnwtwfq) · Grafana Labs · 2 upvotes · 0 comments - [The End of Manual Instrumentation: Scaling Observability with OTel OBI & Coralogix](https://daily.dev/posts/the-end-of-manual-instrumentation-scaling-observability-with-otel-obi-coralogix-hapgdb1o8) · Coralogix · 0 upvotes · 0 comments --- Tags: [#kubernetes](https://daily.dev/tags/kubernetes), [#observability](https://daily.dev/tags/observability), [#opentelemetry](https://daily.dev/tags/opentelemetry), [#helm](https://daily.dev/tags/helm), [#coralogix](https://daily.dev/tags/coralogix) [View this post on daily.dev](https://daily.dev/posts/zero-code-instrumentation-in-kubernetes-without-the-instrumentation-crd-c6edqijet)
