聰明的投資者都是看財報，看法說會，一般網友說的會比較法說會及財報準嗎？我個人是不相信，所以我在追蹤一檔股票時，財報、法說會在我心目中才是第一，這才是專業的人給出的結果，這種結果可信度就非常的高
docker & docker-compose 一堆坑
FROM alpine
RUN apk –no-cache upgrade
RUN apk update &&\
apk add bash
Use chown 1000 xxxoo xxxooo file name
logtest: build: context: logtest/ volumes: - ./logtest/logs:./logs:rw networks: - elk command: | /bin/sh -c '/bin/sh -s << EOF echo "Start filebeat...." filebeat run -c ./filebeat.yml -v & sleep 2 while [ ! -f ./logs/filebeat ] do sleep 2 done chown 1000 ./logs/filebeat tail -f /dev/null EOF'

解决方案为在filebeat里面新增一个fields字段，service : GameStatis都是自己定义的，定义完成后使用Logstash的if 判断，条件为if [fields][service] == “GameStatis”.就可以了。
docker-compose.yml
services: elasticsearch: logstash: kibana: nginx: docker-compose run ngnix
docker-compose run kibana

4 bit => hex 0000 2*2*2*2 = 16
so
one byte = 4bit + 4bit = hex + hex
