Logback日志输出到ELK

用docker-compose本机部署elk

docker-compose.yml

    command: logstash -f /etc/logstash/conf.d/logstash.conf  #logstash 启动时使用的配置文件
    volumes:
      - $PWD/logstash/conf.d:/etc/logstash/conf.d  #logstash 配文件位置
      - $PWD/logstash/config/logstash.yml:/usr/share/logstash/config/logstash.yml  #logstash 配文件位置

    networks:
      - elk

logstash.conf

input {

    codec => json_lines
  }

  elasticsearch {
    hosts => ["http://es01:9200"]

docker-compose 命令

docker-compose up -d   		# 启动
docker-compose down 			# 停止
docker logs -f logstash   # 查看 logstash 输出的日志，这个方便调试
