3.2.6.2. 手动注入 sidecar

Red Hat OpenShift distributed tracing platform Operator 只能自动将 Jaeger Agent sidecar 注入 Deployment 工作负载。对于 Deployment 以外的控制器类型，如 StatefulSets 和 'DaemonSets，您可以在规格中手动定义 Jaeger 代理 sidecar。

以下片段显示了您可以在 Jaeger 代理 sidecar 的 containers 部分中包含的手动定义：

StatefulSet 的 sidecar 定义示例

apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: example-statefulset
  namespace: example-ns
  labels:
    app: example-app
spec:

    spec:
      containers:
        - name: example-app
          image: acme/myapp:myversion
          ports:
            - containerPort: 8080
              protocol: TCP
        - name: jaeger-agent
          image: registry.redhat.io/distributed-tracing/jaeger-agent-rhel7:<version>
           # The agent version must match the Operator version
          imagePullPolicy: IfNotPresent
          ports:
            - containerPort: 5775
              name: zk-compact-trft
              protocol: UDP
            - containerPort: 5778
              name: config-rest
              protocol: TCP
            - containerPort: 6831
              name: jg-compact-trft
              protocol: UDP
            - containerPort: 6832
              name: jg-binary-trft
              protocol: UDP
            - containerPort: 14271
              name: admin-http
              protocol: TCP
          args:
            - --reporter.grpc.host-port=dns:///jaeger-collector-headless.example-ns:14250
            - --reporter.type=grpc

apiVersion: apps/v1

          image: registry.redhat.io/distributed-tracing/jaeger-agent-rhel7:<version>
           # The agent version must match the Operator version
          imagePullPolicy: IfNotPresent
          ports:

              protocol: UDP
            - containerPort: 14271
              name: admin-http
              protocol: TCP
          args:
            - --reporter.grpc.host-port=dns:///jaeger-collector-headless.example-ns:14250
            - --reporter.type=grpc
