AWSFireLens轻松实现容器日志处理

applog应用程序和fluent-bit共享磁盘，日志内容是json格式数据，输出到S3也是JSON格式

applog应用部分在applog目录：

Dockerfile文件内容
FROM alpine
RUN mkdir -p /data/logs/
COPY testlog.sh /bin/
RUN chmod 777 /bin/testlog.sh
ENTRYPOINT ["/bin/testlog.sh"]

testlog.sh文件内容
#!/bin/sh
while :
do
   echo "{"server_date":"2020-01-19","hostname":"ip-172-31-43-24.cn-northwest-1.compute.internal","pid":5404,"method":"POST","clientIP":"10.11.12.13","countryCode":"ID","url":"/v1/mail/list","status":"200","latency":7,"length":24,"userId":9536605,"code":20001}" >> /data/logs/access.log
   echo "{"server_date":"2020-01-19","hostname":"ip-172-31-43-24.cn-northwest-1.compute.internal","pid":1000,"method":"GET","clientIP":"20.21.22.23","countryCode":"ID","url":"/v1/mail/list","status":"500","latency":10,"length":12,"userId":1010001,"code":10001}" >> /data/logs/error.log
sleep 10
done

fluent-bit部分在fluent-bit目录：

Dockerfile文件内容
FROM amazon/aws-for-fluent-bit:latest
ADD extra.conf /extra.conf

extra.conf文件内容
[SERVICE]
    Parsers_File /fluent-bit/parsers/parsers.conf
    Flush 1
    Grace 30

[INPUT]
    Name tail
    Path /data/logs/access.log
    Tag access

[INPUT]
    Name tail
    Path /data/logs/error.log
    Tag error

[FILTER]
    Name parser
    Match *
    Key_Name log
    Parser json  
    Reserve_Data True

[OUTPUT]
    Name firehose
    Match access
    region us-east-1
    delivery_stream fluentbit-access

[OUTPUT]
    Name firehose
    Match error
    region us-east-1
    delivery_stream fluentbit-error  #要在firehouse里面设置

打镜像步骤：
cd fleuntbit
docker build -t fleuntbit:v3 .
docker tag fleuntbit:v3 402097323/fleuntbit:v3
docker push 402097323/fleuntbit:v3
