Docker安装logstash的详细过程

编辑docker-compose.yml，内容如下：

version: '3'
services:
  logstash02:
    image: logstash:6.4.1
    hostname: logstash02
    container_name: logstash02
    ports:
      - "5045:5045" #设置端口
    environment:
      xpack_monitoring_enabled: "false"
      pipeline.batch.size: 10
    volumes:
      - ./logstash/logstash.conf:/usr/share/logstash/pipeline/logstash.conf
    network_mode: "host"
    restart: always

./logstash/logstash.conf文件内容如下：

version: '3'
services:
  logstash02:
    image: logstash:6.4.1
    hostname: logstash02
    container_name: logstash02
    ports:
      - "5045:5045" #设置端口
    environment:
      xpack_monitoring_enabled: "false"
      pipeline.batch.size: 10
    volumes:
      - ./logstash/logstash.conf:/usr/share/logstash/pipeline/logstash.conf
    network_mode: "host"
    restart: always

然后运行docker-compose up启动logstash容器，在进行logstash测试的时候，

/usr/share/logstash/bin/logstash  -e 'input { stdin{} } output { stdout{ codec => rubydebug }}'

会提示 logstash实例已存在，如果要运行多个logstash实例，则需要通过命令定义path.data，如下：

bin/logstash -f <config_file.conf> --path.data path

/usr/share/logstash/bin/logstash --path.data /usr/share/logstash/data02 -e 'input { stdin{} } output { stdout{ codec => rubydebug }}'

输出如下：

输出到es、文件：

/usr/share/logstash/bin/logstash --path.data /usr/share/logstash/data02  -e 'input { stdin{} } output { elasticsearch {hosts => ["127.0.0.1:9200"] index => "logstashtest_%{+yyyy.mm.dd}" }}'

/usr/share/logstash/bin/logstash -e 'input { stdin{} } output { file { path => "/tmp/test_%{+yyyy.mm.dd}.log"}}'
