10.2. 配置 APIcast 进行追踪

流程

1. 为 APIcast 工具创建配置文件：

   • 配置文件规格在 NGINX 检测库存储库中定义。

     $ oc apply -f - <<EOF

     apiVersion: v1
     kind: Secret
     metadata:
       name: otel-config
     type: Opaque
     stringData:
       config.json: |
         # "otlp" is the only supported exporter in APIcast
         exporter = "otlp"
         processor = "simple"
         [exporters.otlp]
         # Alternatively the OTEL_EXPORTER_OTLP_ENDPOINT environment variable can also be used.
         host = "${COLLECTOR_HOST}"
         port = ${COLLECTOR_PORT}
         # Optional: enable SSL, for endpoints that support it
         # use_ssl = true
         # Optional: set a filesystem path to a pem file to be used for SSL encryption
         # (when use_ssl = true)
         # ssl_cert_path = "/path/to/cert.pem"
         [processors.batch]
         max_queue_size = 2048
         schedule_delay_millis = 5000
         max_export_batch_size = 512
         [service]
         name = "apicast" # Opentelemetry resource name
     EOF

2. 定义指定 openTelemetry 属性的 APIcast 自定义资源(CR)。在 CR 定义中，将 openTelemetry.tracingConfigSecretRef.name 属性设置为包含 openTelemetry 配置详情的 secret 的名称。以下示例显示有关配置 openTelemetry 的内容：

   apiVersion: apps.3scale.net/v1alpha1
   kind: APIcast
   metadata:
     name: apicast1
   spec:
     ...
     openTelemetry:
       enabled: true
       tracingConfigSecretRef:
         name: "$NAME_OF_SECRET"
