apache skywalking 7.0.0无法在kubernetes集群中获取服务名称

Question

我使用Kubernetes(v1.16.0)集群中的apache skywalking(7.0.0)作为我的APM工具，但现在我无法在仪表板中获取服务名称。这是我在Dockerfile中的收集器配置：

FROM openjdk:8-jre-alpine

ADD dolphin-service/build/libs/dolphin-service-1.0.0-SNAPSHOT.jar /root/dolphin-service-1.0.0-SNAPSHOT.jar
ADD script/start-docker.sh /root/start-docker.sh

EXPOSE 11005
# ENTRYPOINT ["sh","/root/start-docker.sh"]

ENTRYPOINT exec java -Xmx256M -Xms128M -Dapp.id=0010020001 -javaagent:/opt/skywalking/agent/skywalking-agent.jar -Dskywalking.agent.service_name=0010020001 -Dskywalking.collector.backend_service=10.254.35.220:11800 -jar /root/dolphin-service-1.0.0-SNAPSHOT.jar

这是我的仪表板UI：

是不是我漏掉了什么？收集的所有数据(端点\缓存\数据库\MQ)，除了service.What之外，我应该做什么来收集服务数据？当我看到日志输出时：

是仪表板默认时间筛选值问题，时间范围不包含数据：

curl 'https://skywalking.example.net/graphql' \
  -H 'authority: skywalking.example.net' \
  -H 'pragma: no-cache' \
  -H 'cache-control: no-cache' \
  -H 'accept: application/json, text/plain, */*' \
  -H 'dnt: 1' \
  -H 'user-agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.97 Safari/537.36' \
  -H 'content-type: application/json;charset=UTF-8' \
  -H 'origin: https://skywalking.example.net' \
  -H 'sec-fetch-site: same-origin' \
  -H 'sec-fetch-mode: cors' \
  -H 'sec-fetch-dest: empty' \
  -H 'referer: https://skywalking.example.net/' \
  -H 'accept-language: en,zh-CN;q=0.9,zh;q=0.8,zh-TW;q=0.7,fr;q=0.6' \
  --data-binary $'{"query":"query queryServices($duration: Duration\u0021) {\\n    services: getAllServices(duration: $duration) {\\n      key: id\\n      label: name\\n    }\\n  }","variables":{"duration":{"start":"2020-06-03 1015","end":"2020-06-23 1030","step":"MINUTE"}}}' \
  --compressed

将时间开始和结束更改为具有收集数据区域。
