Docker-compose部署ELK的示例代碼

環境

主機IP 192.168.0.9
Docker version 19.03.2
docker-compose version 1.24.0-rc1
elasticsearch version 6.6.1
kibana version 6.6.1
logstash version 6.6.1

一、ELK-dockerfile文件編寫及配置文件

● elasticsearch

1、elasticsearch-dockerfile

FROM centos:latest
ADD elasticsearch-6.6.1.tar.gz /usr/local/
COPY elasticsearch.yml /usr/local/elasticsearch-6.6.1/config/
COPY jdk1.8 /usr/local/
ENV JAVA_HOME=/usr/local/jdk1.8
ENV CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
ENV PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH:$HOME/bin
RUN groupadd elsearch && \

useradd elsearch -g elsearch -p elasticsearch && \

chown -R elsearch:elsearch /usr/local/elasticsearch-6.6.1 && \

cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && \

echo "Asia/shanghai" > /etc/timezone && \

yum install which -y && \

mkdir /opt/data && \

mkdir /opt/logs
EXPOSE 9200 9300
#主要是切換到elsearch用戶啟動es
USER elsearch
WORKDIR /usr/local/elasticsearch-6.6.1/bin/
ENTRYPOINT ["./elasticsearch"]

2、elasticsearch.yml

[root@localhost elasticsearch]# egrep "^[^#]" elasticsearch.yml 
cluster.name: es-cluster
node.name: node-1
path.data: /opt/data
path.logs: /opt/logs
network.host: 0.0.0.0
http.port: 9200
cluster.routing.allocation.disk.threshold_enabled: true
cluster.routing.allocation.disk.watermark.low: 94%
cluster.routing.allocation.disk.watermark.high: 96%
cluster.routing.allocation.disk.watermark.flood_stage: 98%
discovery.zen.minimum_master_nodes: 1

● logstash

1、logstash-dockerfile

FROM centos:latest
ADD logstash-6.6.1.tar.gz /usr/local/
COPY logstash.yml /usr/local/logstash-6.6.1/config/
COPY logstash.conf /usr/local/logstash-6.6.1/config/
COPY jdk1.8 /usr/local/
COPY start.sh /start.sh
ENV JAVA_HOME=/usr/local/jdk1.8
ENV CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/jre/lib
ENV PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH:$HOME/bin
RUN mkdir /opt/data && \

mkdir /opt/logs && \

chmod +x /start.sh
ENTRYPOINT ["/start.sh"]

2、logstash-start.sh

#!/bin/bash
/usr/local/logstash-6.6.1/bin/logstash -f /usr/local/logstash-6.6.1/config/logstash.conf

3、logstash.yml

[root@localhost logstash]# egrep "^[^#]" logstash.yml 
path.data: /opt/data
path.logs: /opt/logs
pipeline.batch.size: 200

4、logstash.conf

input {
 file {
  path => "/usr/local/nginx/logs/access.log"
  type => "nginx"
  start_position => "beginning"
  sincedb_path => "/dev/null"
 }
 file {
  path => "/var/log/secure"
  type => "secure"
  start_position => "beginning"
  sincedb_path => "/dev/null"
 }
}
#詳細說明可以查看我之前的博客
filter {
  grok {
    match => {
      "message" => '(?<clientip>[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}) - - (?<requesttime>\[[0-9]{1,2}\/[A-z]+\/[0-9]{4}\:[0-9]{2}\:[0-9]{2}\:[0-9]{2} \+[0-9]*\]) "(?<requesttype>[A-Z]+) (?<requesturl>[^ ]+) (?<requestv>HTTP/\d\.\d)" (?<requestnode>[0-9]+) (?<requestsize>[0-9]+) "(?<content>[^ ]|(http|https)://[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\/)" "(?<ua>(a-Z|0-9| |.)+)"'
    }
     remove_field => ["message","log","beat","offset","prospector","host","@version"]
  }
}
#output指向es容器
output {
 if [type] == "nginx" {
 elasticsearch {
  hosts => ["es:9200"]
  index => "nginx-%{+YYYY.MM.dd}"
    }
   }
 else if [type] == "secure" {
  elasticsearch {
  hosts => ["es:9200"]
  index => "secure-%{+YYYY.MM.dd}"
    }
   }
 }

● kibana

1、kibana-dockerfile

FROM centos:latest
ADD kibana-6.6.1-linux-x86_64.tar.gz  /usr/local/
COPY kibana.yml /usr/local/kibana-6.6.1-linux-x86_64/config/
COPY start.sh /start.sh
RUN chmod +x /start.sh
EXPOSE 5601
ENTRYPOINT ["/start.sh"]

2、kibana.yml

[root@localhost kibana]# egrep "^[^#]" kibana.yml 
server.port: 5601
server.host: "0.0.0.0"
#指向es容器的9200端口
elasticsearch.hosts: ["http://es:9200"]

3、kibana-start.sh

#!/bin/bash
/usr/local/kibana-6.6.1-linux-x86_64/bin/kibana

二、docker-compose,yml文件編寫

[root@localhost elk_dockerfile]# cat docker-compose.yml


version: '3.7'
services:
 elasticsearch:
  image: elasticsearch:elk
  container_name: es
  networks:
   - elk
  volumes:
   - /opt/data:/opt/data
   - /opt/logs:/opt/logs
  expose:
   - 9200
   - 9300
  restart: always
  depends_on:
   - logstash
   - kibana
 logstash:
  image: logstash:elk
  container_name: logstash
  networks:
   - elk
  volumes:
   - /opt/logstash/data/:/op/data
   - /opt/logstash/logs/:/opt/logs

   - /usr/local/nginx/logs:/usr/local/nginx/logs
   - /var/log/secure:/var/log/secure
  restart: always
 kibana:
  image: kibana:elk
  container_name: kibana
  ports:
   - 5601:5601
  networks:
   - elk
  volumes:
   - /opt/elk/elk_dockerfile/kibana/kibana.yml:/usr/local/kibana-6.6.1-linux-x86_64/config/kibana.yml
