AWSFireLens轻松实现容器日志处理

news 2025/8/13 12:07:34

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
