将tomcat日志从tomcat docker容器收集到Filebeat docker容器

2019年7月28日 301次阅读

我有一个Tomcat docker容器和Filebeat docker容器都启动并运行.

我的目标：我需要从运行Tomcat容器到Filebeat容器收集tomcat日志.

问题：我不知道如何从Tomcat容器中获取收集的日志文件.

到目前为止我尝试过：我尝试创建一个docker卷并将tomcat日志添加到该卷并从filebeat容器访问该卷,但结果没有成功.

结构：我在项目Logstash(项目的根目录)下编写了docker-compose.yml文件,其中包含以下项目结构.(这里我想从一个配置文件启动并运行Elasticsearch,Logstash,Filebeat和Kibana docker容器). docker-containers(项目的根目录)具有以下结构(这里我想从一个配置文件中启动并运行Tomcat,Nginx和Postgres容器).

> Logstash：包含4个主要子目录(Filebeat,Logstash,Elasticsearch和Kibana),ENV文件和docker-compose.yml文件.两个子目录都包含Dockerfiles来提取图像和构建容器.
> docker-containers：包含3个主要子目录(Tomcat,Nginx和Postgres). ENV文件和docker-compose.yml文件.两个子目录都包含单独的Dockerfiles以提取docker镜像并构建容器.
>注意：我认为这个基本结构有助于理解我的要求.

我的问题：

>我需要知道从tomcat容器中获取收集的tomcat日志的正确方法,并通过filebeat容器将它们转发到logstash容器.

任何讨论,回答或任何有助于理解这种方法的帮助都是非常期待的.

谢谢.

最佳答案 所以loooong …在所有容器中创建共享卷并设置tomcat以将日志文件保存到该文件夹​​中.如果您可以将所有服务放入一个docker-compose.yml,只需在内部设置卷：

泊坞窗,compose.yml

version: '3'
services:
  one:
    ...
    volumes:
      - logs:/var/log/shared
  two:
    ...
    volumes:
      - logs:/var/log/shared
volumes:
  logs:

如果您需要多个docker-compose.yml文件,请使用docker volume创建日志并将其映射到两个撰写文件中,提前全局创建卷：

version: '3'
services:
  one:
    ...
    volumes:
      - logs:/var/log/shared
  two:
    ...
    volumes:
      - logs:/var/log/shared
volumes:
  logs:
    external: true
