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

Question

我的目标：我需要收集从运行的tomcat容器到Filebeat容器的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的内容：我尝试创建一个docker卷并将tomcat日志添加到该卷中，并从filebeat容器访问该卷，但没有成功。

docker-containers：包含3个主子目录(Tomcat、Nginx和Postgres）。ENV文件和docker-compose.yml文件。这两个子目录都包含单独的Dockerfiles来提取docker映像并构建容器。

注意：我认为这个基本结构有助于理解我的需求。

docker-compose.yml文件

  elasticsearch:
    container_name: OTP-Elasticsearch

filebeat.inputs:
- type: log
  enabled: true
  paths:
    - /usr/local/tomcat/logs/.*log
output.logstash:
  hosts: ["logstash:5044"]

其他信息：

• 我使用的系统是Ubuntu 18.04
• 我的目标是从正在运行的tomcat容器中收集tomcat日志，并将它们转发给Logstash和filter日志，然后将这些日志转发给Elasticsearch，最后转发给Kibana，以便进行可视化。
• 现在我可以收集本地计算机（主机）日志，并在Kibana中可视化它们。(/var/log/)

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

Docker-compose.yml

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

如果需要几个docker-compose.yml文件，请预先使用docker volume create logs全局创建卷，并将其映射到两个compose文件中：

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