          mountPath: /usr/share/logstash/pipeline/cdn_akamai.conf
          subPath: cdn_akamai.conf
        - name: logstash-jvm-options-config
          mountPath: /usr/share/logstash/config/jvm.options
          subPath: jvm.options
        - name: pipeline-config
          mountPath: /usr/share/logstash/config/pipelines.yml
          subPath: pipelines.yml
        command:
        - logstash
      volumes:
      - name: cdn-akamai-pipe-config
        configMap:
          name: cdn-akamai-pipe
      - name: logstash-jvm-options-config
        configMap:
          name: logstash-jvm-options
      - name: pipeline-config
        configMap:
          name: pipeline-akamai

kind: Service
apiVersion: v1

  selector:
    app: cdn-akamai-pipe
  ports:
  - protocol: TCP
    port: 9600
    targetPort: 9600
    name: logstash

并使用下一个命令

kubectl create configmap logstash-jvm-options --from-file jvm.options
kubectl create configmap cdn-akamai-pipe --from-file cdn_akamai.conf
kubectl create configmap pipeline-akamai --from-file pipelines.yml
kubectl create -f cdn_akamai.yml

文件在哪里

Data  
====
pipelines.yml: 
----
- pipeline.id: main
  path.config: "/usr/share/logstash/pipeline/cdn_akamai.conf


Data
====
jvm.options:

-XX:+HeapDumpOnOutOfMemoryError
-Djava.security.egd=file:/dev/urandom

Data
====
cdn_akamai.conf:
----
input {stdin{}}
output {stdout{}}

但我得到 Error 或 CrashLoopBackOff 作为

cdn-akamai-pipe-74c64757b9-t4k2f   0/1     Error     7          12m

我运行了一个hello word pod来验证我的集群是否正常，并且这个 pod 运行良好。

请问你能帮帮我吗？我的卷、服务、语法有什么问题吗？你看到什么了吗？
