What happened?

Description

When using Go auto-instrumentation on Kubernetes Jobs or CronJobs, the injected sidecar container does not terminate when the main application container exits. This causes the Job to remain in Running state indefinitely.

apiVersion: batch/v1
kind: CronJob
metadata:
  name: test-job
spec:
  schedule: "*/5 * * * *"
  jobTemplate:
    spec:
      template:
        metadata:
          annotations:
            instrumentation.opentelemetry.io/inject-go: "grafana/apm-instrumentation"
            instrumentation.opentelemetry.io/otel-go-auto-target-exe: /app
        spec:
          containers:
            - name: app
              image: my-go-app:latest
              command: ["/app"]

Expected Behavior

When the main container exits (code 0 or 1), the sidecar should terminate and the Job should complete.

Actual Behavior

• Main container: Terminated (exit code 0 or 1)
• Sidecar container: Running (indefinitely)
• Pod status: Running
• Job status: Never completes
