📝 WalkthroughWalkthroughThe operator now always reconciles the OTEL Collector and configures secure in-cluster OTLP export. Service-ca certificates are mounted for the collector.

Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The added Jaeger TLS test script has a bounded cleanup bug when invoked with --delete and uses a mutable image tag that can make future test deployments unpredictable.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Fix namespace resolution for --delete without a namespace argument.
The usage text at line 8 marks NAMESPACE optional for --delete. If the user runs hack/deploy-jaeger-tls.sh --delete, then $2 is unset and NAMESPACE becomes --delete. Every oc delete ... -n --delete command then fails, and set -e aborts the cleanup.
Parse the flag before resolving the namespace.

Use a shared error constant for the OTEL Service lookup.
Line 90 introduces a literal error prefix. Define or use the shared OTEL Service lookup error constant, then wrap the error as fmt.Errorf("%s: %w", utils.Err..., err).
As per coding guidelines, wrap errors with fmt.Errorf("%s: %w", ErrConstant, err). As per path instructions, use shared constants from internal/controller/utils/errors.go.

Remove the remaining image-gated OTEL Collector steps.
The OTEL Collector is now present in both always-included lists. When r.Options.OtelCollectorImage != "", the existing blocks at Lines 382-389 and Lines 533-551 append the same resource and deployment reconciliations again. This runs both OTEL reconciliations twice and adds duplicate OtelCollectorReady conditions to newStatus. The else branch can also report Disabled even though the Collector is unconditionally reconciled.
Keep the new unconditional entries and remove the old image-gated blocks.

OpenTelemetry Collector configtls ca_file include_system_ca_certs_pool custom CA system certificate pool behavior
💡 Result:
In the OpenTelemetry Collector, the include_system_ca_certs_pool configuration setting determines whether the system's default certificate authority (CA) pool is loaded alongside any custom CA certificates you provide [1][2]. Behavior and Configuration Details: 1. Default Behavior (When not configured): By default, include_system_ca_certs_pool is false [1][2]. If you define a custom CA using ca_file or ca_pem and leave include_system_ca_certs_pool as false, the OpenTelemetry Collector will use only the custom CA certificates you provided and will not include the system's root CA certificates [3][4]. 2. Enabling System Pool: When you set include_system_ca_certs_pool: true, the OpenTelemetry Collector loads the system certificate authority pool and appends your custom CA certificates (provided via ca_file or ca_pem) to that pool [3][4]. This is useful when you need to trust both the public internet's root CAs and your own internal or private CAs [1][2]. 3. Empty Configuration: If you do not specify a ca_file or ca_pem (i.e., they are empty), the Collector defaults to using the system root CAs regardless of the include_system_ca_certs_pool setting, as an empty configuration naturally falls back to the system's default trust store [1][3]. 4. Implementation Note: The implementation in the OpenTelemetry Collector's configtls package retrieves the system pool via the Go x509 library's system certificate pool functionality [3][4]. If include_system_ca_certs_pool is enabled, the collector initializes the certificate pool with the system's certs first, then appends the custom certs parsed from your file or PEM string [3][4].

Preserve system CA trust for configurable tracing endpoints.
spec.audit.tracingEndpoint accepts external OTLP backends, but buildCollectorConfigYAML forces tls.ca_file to the OpenShift service-CA bundle. The collector then excludes system roots unless include_system_ca_certs_pool is enabled. Public-CA endpoints can therefore fail TLS verification. Enable the system CA pool and support a separate CA path for private backends.
