Kubernetes 日志收集案例二 【实现daemonset和sidcar日志收集】
日志案例二、sidecar模式构架
一、制作logstash-sidecar镜像
#logstash-image-Dockerfile 每个node中添加logstash
[root@xianchaomaster1 1.logstash-image-Dockerfile]# ll

-rwxr-xr-x 1 root root 298 Apr 6 19:58 build-commond.sh

[root@xianchaomaster1 1.logstash-image-Dockerfile]# cat build-commond.sh
#!/bin/bash

#提前拉镜像
docker pull logstash:7.12.1
#编辑Dockerfile
vim Dockerfile

USER root
WORKDIR /usr/share/logstash
ADD logstash.yml /usr/share/logstash/config/logstash.yml
ADD logstash.conf /usr/share/logstash/pipeline/logstash.conf
[root@xianchaomaster1 1.logstash-image-Dockerfile]# cat logstash.conf
input {

}}
}
[root@xianchaomaster1 1.logstash-image-Dockerfile]# cat logstash.yml

#创建镜像同步到harbor
bash build-command.sh
#节点提早下载镜像
crictl pull harbor.sheca.com/baseimages/logstash:v7.12.1-sidecar二、创建Deployment-Tomcat应用
[root@xianchaomaster1 2.sidecar-logstash]# cat 2.tomcat-app1.yaml
kind: Deployment

#
kubectl apply -f 2.tomcat-app1.yaml三、编辑Tomcat Service文件 NodePort暴露端口
#NodePort端口：30090
[root@xianchaomaster1 2.sidecar-logstash]# cat 3.tomcat-service.yaml
---

#
kubectl apply -f 3.tomcat-service.yaml![]()
四、配置把Kafka中的数据传入Elasticsearch中
[root@xianchaomaster1 2.sidecar-logstash]# cat 4.logsatsh-sidecar-kafka-to-es.conf
input {
kafka {
bootstrap_servers => "192.168.40.180:9092,192.168.40.181:9092,192.168.40.182:9092"
topics => ["tomcat-app1-topic"]
codec => "json"
}
}
output {
#if [fields][type] == "app1-access-log" {
if [type] == "app1-sidecar-access-log" {
elasticsearch {
hosts => ["192.168.40.180:9200","192.168.40.181:9200"]
index => "sidecar-app1-accesslog-%{+YYYY.MM.dd}"
}
}
#if [fields][type] == "app1-catalina-log" {
if [type] == "app1-sidecar-catalina-log" {
elasticsearch {
hosts => ["192.168.40.180:9200","192.168.40.181:9200"]
index => "sidecar-app1-catalinalog-%{+YYYY.MM.dd}"
}
}
# stdout {
# codec => rubydebug
# }
}
[root@xianchaomaster1 conf.d]# cp 4.logsatsh-sidecar-kafka-to-es.conf /etc/logstash/conf.d/logstash-sidercar-kafka-to-es.conf
[root@xianchaomaster1 conf.d]# systemctl restart logstash
[root@xianchaomaster1 conf.d]# tail -f /var/log/logstash/logstash-plain.log

五、添加 Kibana索引-查看两个索引日志
#由于Pod做了liveness和readness的探测 所有访问日志 accesslog 有数据
5.1 此时应用日志没有，自己在容器中catalina.out 中添加数据 、再kibana中添加索引查看

5.2 测试 local_access log 因为是两个容器 找到sidercar-container容器 查看/var/log/applog
