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: elasticsearch network-test: external: hostname: elasticsearch container_name: elasticsearch restart: always volumes: - /opt/elasticsearch/data:/usr/share/elasticsearch/data kibana: image: kibana network-test: external: hostname: kibana container_name: kibana restart: always environment: ELASTICSEARCH_URL: :9200/ ports: - 5601:5601 logstash: image: logstash network-test: external: hostname: logstash container_name: logstash restart: always volumes: - /opt/logstash/conf:/opt/logstash/conf command: logstash -f /opt/logstash/conf/ filebeat: image: prima/filebeat network-test: external: hostname: filebeat container_name: filebeat restart: always volumes: - /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 => 5044 type => beats } tcp { port => 5000 type => syslog } } filter { if[type] == "tomcat-log" { multiline { patterns_dir => "/opt/logstash/conf/patterns" pattern => "(^%{TOMCAT_DATESTAMP})|(^%{CATALINA_DATESTAMP})" negate => true what => "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: syslog options: 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/filebeat COPY 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
