docker 容器日志集中 ELK + filebeat

docker 容器日志集中 ELK

ELK 基于 ovr 网络下

docker-compose.yaml

version: '2'
networks:network-test:external:name: ovr0
services:elasticsearch:image: elasticsearchnetwork-test:external:hostname: elasticsearchcontainer_name: elasticsearchrestart: alwaysvolumes:- /opt/elasticsearch/data:/usr/share/elasticsearch/datakibana:image: kibananetwork-test:external:    hostname: kibanacontainer_name: kibanarestart: alwaysenvironment:ELASTICSEARCH_URL: http://elasticsearch:9200/ports:- 5601:5601logstash:image: logstashnetwork-test:external:hostname: logstashcontainer_name: logstashrestart: alwaysvolumes:- /opt/logstash/conf:/opt/logstash/confcommand: logstash -f /opt/logstash/conf/filebeat:image: prima/filebeatnetwork-test:external:hostname: filebeatcontainer_name: filebeatrestart: alwaysvolumes:- /opt/filebeat/conf/filebeat.yml:/filebeat.yml- /opt/upload:/data/logs- /opt/filebeat/registry:/etc/registry

filebeat说明:
filebeat.yml 挂载为 filebeat 的配置文件
logs 为容器挂载日志的目录
registry 读取日志的记录，防止filebeat 容器挂掉，需要重新读取所有日志

logstash 配置文件如下：

第一种：使用 patterns .

logstash.conf： (配置了二种输入模式， filebeats, syslog)

input {beats {port => 5044type => beats}tcp {port => 5000type => syslog}}filter {if[type] == "tomcat-log" {multiline {patterns_dir => "/opt/logstash/conf/patterns"pattern => "(^%{TOMCAT_DATESTAMP})|(^%{CATALINA_DATESTAMP})"negate => truewhat => "previous"}if "ERROR" in [message] {    #如果消息里有ERROR字符则将type改为自定义的标记mutate { replace => { type => "tomcat_catalina_error" } }}else if "WARN" in [message] {mutate { replace => { type => "tomcat_catalina_warn" } }}else if "DEBUG" in [message] {mutate { replace => { type => "tomcat_catalina_debug" } }}else {mutate { replace => { type => "tomcat_catalina_info" } }}grok{patterns_dir => "/opt/logstash/conf/patterns"match => [ "message", "%{TOMCATLOG}", "message", "%{CATALINALOG}" ]remove_field => ["message"]    #这表示匹配成功后是否删除原始信息，这个看个人情况，如果为了节省空间可以考虑删除}date {match => [ "timestamp", "yyyy-MM-dd HH:mm:ss,SSS Z", "MMM dd, yyyy HH:mm:ss a" ]}}    if[type] == "nginx-log" {if '"status":"404"' in [message] {mutate { replace => { type => "nginx_error_404" } }}else if '"status":"500"' in [message] {mutate { replace => { type => "nginx_error_500" } }}else if '"status":"502"' in [message] {mutate { replace => { type => "nginx_error_502" } }}else if '"status":"403"' in [message] {mutate { replace => { type => "nginx_error_403" } }}else if '"status":"504"' in [message] {mutate { replace => { type => "nginx_error_504" } }}else if '"status":"200"' in [message] {mutate { replace => { type => "nginx_200" } }}grok {remove_field => ["message"]    #这表示匹配成功后是否删除原始信息，这个看个人情况，如果为了节省空间可以考虑删除}}
}output {elasticsearch { hosts => ["elasticsearch:9200"]}#stdout { codec => rubydebug }    #输出到屏幕上
}

下面我们配置容器日志输出：

docker里，标准的日志方式是用Stdout, docker 里面配置标准输出，只需要指定： syslog 就可以了。

对于 stdout 标准输出的 docker 日志，我们使用 logstash 来收集日志就可以。

我们在 docker-compose 中配置如下既可：

      logging:driver: syslogoptions:syslog-address: 'tcp://logstash:5000'

但是一般来说我们都是文件日志，那么我们就可以直接用filebeat

对于 filebeat 我们使用官方的 dockerhub 的 prima/filebeat 镜像。

官方的镜像中，我们需要编译一个filebeat.yml 文件，官方说明中有两种方案：

第一是 -v 挂载 -v /path/filebeat.yml:/filebeat.yml

第二是 dockerfile 的时候

FROM prima/filebeatCOPY filebeat.yml /filebeat.yml

编译一个 filebeat.yml 文件。

filebeat.yml 支持单一路径的 prospector，也支持多个 prospector或者每个prospector多个路径。

paths 可使用多层匹配，如： /var/log/messages* , /var/log/* , /opt/nginx/*/*.log

例：

filebeat:prospectors:-paths:- "/data/logs/catalina.*.out"input_type: filebeat-logdocument_type: tomcat-log-  paths:- "/data/logs/nginx*/logs/*.log"input_type: filebeat-logdocument_type: nginx-logregistry_file: /etc/registry/markoutput:logstash:hosts: ["logstash:5044"]logging:files:rotateeverybytes: 10485760 # = 10MB

filebeat 需要在每台需要采集的机器上面都启动一个容器。

执行 docker-compose up -d 查看启动的容器

加载 filebeat 模板进入 elasticsearch 容器中  (  docker exec -it elasticsearch bash  )curl -O https://gist.githubusercontent.com/thisismitch/3429023e8438cc25b86c/raw/d8c479e2a1adcea8b1fe86570e42abab0f10f364/filebeat-index-template.jsoncurl -XPUT 'http://elasticsearch:9200/_template/filebeat?pretty' -d@filebeat-index-template.json


filebeat-index-template.json

{"mappings": {"_default_": {"_all": {"enabled": true,"norms": {"enabled": false}},"dynamic_templates": [{"template1": {"mapping": {"doc_values": true,"ignore_above": 1024,"index": "not_analyzed","type": "{dynamic_type}"},"match": "*"}}],"properties": {"@timestamp": {"type": "date"},"message": {"type": "string","index": "analyzed"},"offset": {"type": "long","doc_values": "true"},"geoip"  : {"type" : "object","dynamic": true,"properties" : {"location" : { "type" : "geo_point" }}}}}},"settings": {"index.refresh_interval": "5s"},"template": "filebeat-*"
}

访问 http://kibana-IP:5601 可以看到已经出来 kibana 了，但是还没有数据

启动一个 nginx 容器

docker-compose

  nginx:image: alpine-nginxnetworks:network-test:hostname: nginxcontainer_name: nginxrestart: alwaysports:- 80:80volumes:- /opt/upload/nginx/conf/vhost:/etc/nginx/vhost- /opt/upload/nginx/logs:/opt/nginx/logs

本地目录 /opt/upload/nginx 必须挂载到 filebeat 容器里面，让filebeat 可以采集到。

可以看到 kibana 已经有数据出来了
