导入并上传镜像

docker load < filebeat6.tar.gz
    
    docker tag prima/filebeat:6 registry.cn-shanghai.aliyuncs.com/yjk-datag/filebeat:6
    
    docker push registry.cn-shanghai.aliyuncs.com/yjk-datag/filebeat:6

应用yaml

kubectl apply -f StatefulSet.yaml

等到容器启动完成

进入容器需要 -c 指定容器name

# 进入应用容器
    kubectl exec -it haozhuo-account-dp-0   -c haozhuo-account  /bin/bash -n test
    # 进入filebeat容器
    kubectl exec -it haozhuo-account-dp-0   -c filebeat  /bin/bash -n test
    
    # 如果不使用-c的话会进入sidecar容器

手动输出error到error日志或者info日志

echo '{"@timestamp":"2020-08-22T15:59:10.014+08:00","@version":1,"message":"请求url:http://192.168.1.164:8030/dingtalk/order/saveOrderDataRecord 入参:","logger_name":"com.haozhuo.common.sys.http.HttpRequest","thread_name":"account-updateOrderBizData_Worker-1","level":"INFO","level_value":20000,"HOSTNAME":"haozhuo-account-dp-0.haozhuo-account.test.svc.cluster.local","tid":"6494f345-b18e-40ac-b4fc-baf851cab191"} ' >> /data/tomcat-haozhuo-account/json.info.2020-08-22.log

观察filebeat 发现采集成功

![format_png 3][]

kubectl logs -f  haozhuo-account-dp-0  filebeat -n test 
    kubectl logs -f  haozhuo-account-dp-0  haozhuo-account -n test
