k8s 搭建微服务日志收集 log-pilot + kafka + logstash + es + kibana
本文采用的是阿里云开源的log-pilot,根据filebeat二次开发而来的,而log-pilot对微服务的日志收集有着巨大的优势的,关于log-pilot更加详细的报告,大家可以看看这篇《利用开源组件Log-pilot搭建Kubernetes日志解决方案》
简单画了个图
各组件版本介绍
log-pilot: 0.9.7
kafka: 2.2.0
zookeeper: 3.4.10
logstash: 6.8.0
es: 6.8.0
kibana: 6.8.0
为了安全起见建议大家可以到 https://hub.docker.com docker官方镜像仓库去下载各个组件的docker镜像
- 部署kafka+zk
#存储大小和相关配置大家可以根据各自情况修改,
#没有具体需求大家可以先保持默认

2. 搭建log-pilot
搭建log-pilot 并把日志打到kafka里面
log-pilot建议大家根据自家日志情况配置好正则表达式收集,然后重新打包成镜像
