ELK学习实验018：filebeat收集docker日志
Filebeat收集Docker日志
1 安装docker
[root@node4 ~]# yum install -y yum-utils device-mapper-persistent-data lvm2
[root@node4 ~]# yum update
[root@node4 ~]# yum-config-manager –add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
[root@node4 ~]# yum makecache fast
[root@node4 ~]# yum -y install docker-ce
[root@node4 ~]# systemctl restart docker
[root@node4 ~]# systemctl enable docker
2 运行一个nginx容器
[root@node4 ~]# docker run –name nginx -p 8081:80 -d nginx
Unable to find image 'nginx:latest' locally latest: Pulling from library/nginx 8ec398bc0356: Pull complete dfb2a46f8c2c: Pull complete b65031b6a2a5: Pull complete Digest: sha256:8aa7f6a9585d908a63e5e418dc5d14ae7467d2e36e1ab4f0d8f9d059a3d071ce Status: Downloaded newer image for nginx:latest 9c29964182697e55e7ca0fd793f1e243a9e404c84868bee814afdb700760ba5a
[root@node4 ~]# docker ps -a

访问http://192.168.132.134:8081/
[root@node4 ~]# docker exec -it 9c2996418269 /bin/bash
3 查看docker日志
[root@node4 ~]# docker logs -f nginx

本地查看
[root@node4 ~]# tail -f /var/lib/docker/containers/9c29964182697e55e7ca0fd793f1e243a9e404c84868bee814afdb700760ba5a/9c29964182697e55e7ca0fd793f1e243a9e404c84868bee814afdb700760ba5a-json.log
是json格式日志
4 filebeat收集
docker的正确日志
错误日志
错误日志再stream显示的stdeer，正确的是stdout，根据这个规则配置filebeat
5 配置filebeat

6 运行多个容器
[root@node4 ~]# docker run –name nginx-v2 -p 8082:80 -v /data:/usr/share/nginx/html -d nginx
[root@node4 ~]# cd /data/
[root@node4 data]# echo “this is second container” > index.html
[root@node4 data]# docker ps -a

访问http://192.168.132.134:8082/
7 配置filebeat收集所有容器
想要收集所有的dokcer日志修改filebeat
filebeat.inputs: ##################################################### ## Nginx log ##################################################### - type: log enabled: true paths: - /usr/local/nginx/logs/access.log json.key_under_root: true json.overwrite_keys: true tags: ["access"] - type: log enabled: true paths: - /usr/local/nginx/logs/error.log tags: ["error"] ##################################################### ## tomcat log ##################################################### - type: log enabled: true paths: - /var/log/tomcat/localhost_access_log.*.txt json.key_under_root: true json.overwrite_keys: true tags: ["tomcat"] ##################################################### ## java log ##################################################### - type: log enabled: true paths: - /usr/local/elasticsearch/logs/my-elktest-cluster.log tags: ["es-java"] multiline.pattern: '^\[' multiline.negate: true multiline.match: "after" ##################################################### ## docker log ##################################################### - type: docker containers.ids: - '*' json.key_under_root: true json.overwrite_keys: true tags: ["docker"] ##################################################### ## Output ##################################################### setup.kibana: host: "192.168.132.131:5601" output.elasticsearch: hosts: ["192.168.132.131:9200","192.168.132.132:9200","192.168.132.133:9200"] #index: "nginx-%{[agent.version]}-%{+yyyy.MM.dd}" indices: - index: "access-%{[agent.version]}-%{+yyyy.MM.dd}" when.contains: tags: "access" - index: "error-%{[agent.version]}-%{+yyyy.MM.dd}" when.contains: tags: "error" - index: "tomcat-access-%{[agent.version]}-%{+yyyy.MM.dd}" when.contains: tags: "tomcat" - index: "javaes-access-%{[agent.version]}-%{+yyyy.MM.dd}" when.contains: tags: "es-java" - index: "docker-access-%{[agent.version]}-%{+yyyy.MM.dd}" when.contains: tags: "docker" stream: "stdout" - index: "docker-error-%{[agent.version]}-%{+yyyy.MM.dd}" when.contains: tags: "docker" stream: "stderr" setup.template.name: "nginx" setup.template.pattern: "nginx-*" setup.template.overwrite: true setup.template.enabled: true setup.ilm.enabled: false
随意访问nginx，查看索引
但是收集到日志以后，所有的容器日志集中在一起，无法分辨，则为每一个容器添加一个标签
使用docker-compose为容器添加新的标签
8 安装docker-compose
参考https://www.cnblogs.com/zyxnhr/p/12158816.html
[root@node4 src]# curl -L https://github.com/docker/compose/releases/download/1.25.0/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose

[root@node4 src]# chmod +x /usr/local/bin/docker-compose
[root@node4 src]# docker-compose –version
docker-compose version 1.25.0, build 0a186604
[root@node4 ~]# vim docker-compose.yaml

10 使用docker-compose发布容器

访问后查看索引
12 修改filebeat再细致划分

访问后
但是没有docker-error-httpd*
经过日志访问后，发现没有stderr的这个标记
