Filebeat收集Docker日志
1 安装docker
[[email protected] ~]# yum install -y yum-utils device-mapper-persistent-data lvm2
[[email protected] ~]# yum update
[[email protected] ~]# yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
[[email protected] ~]# yum makecache fast
[[email protected] ~]# yum -y install docker-ce
[[email protected] ~]# systemctl restart docker
[[email protected] ~]# systemctl enable docker
2 运行一个nginx容器
[[email protected] ~]# docker run --name nginx -p 8081:80 -d nginx

[[email protected] ~]# 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
[[email protected] ~]# docker run --name nginx-v2 -p 8082:80 -v /data:/usr/share/nginx/html -d nginx
[[email protected] ~]# cd /data/
[[email protected] data]# echo "this is second container" > index.html

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

但是没有docker-error-httpd*
经过日志访问后,发现没有stderr的这个标记
关于Docker的日志收集介绍到这里
