我的ec2实例上运行了几个Docker容器。

我想将这些容器中的日志直接保存到Logstash( flex 云)中。

当我尝试手动安装Filebeat时,一切正常。
我已经使用下载了它

curl -L -O https://artifacts.elastic.co/downloads/beats/filebeat/filebeat-7.2.0-linux-x86_64.tar.gz

我已将其解压缩,将 filebeat.yml 配置更改为
filebeat.inputs:

- type: log

  enabled: true

  fields:
    application: "myapp"

  fields_under_root: true

  paths:
    - /var/lib/docker/containers/*/*.log

cloud.id: "iamnotshowingyoumycloudidthisisjustfake"
cloud.auth: "elastic:mypassword"

这工作得很好,我可以在Kibana中搜索应用程序:“myapp” 后找到我的日志。

但是,当我尝试从Docker运行Filebeat时,没有成功。

这是我的docker-compose.yml的filebeat部分
filebeat:
    image: docker.elastic.co/beats/filebeat:7.2.0
    container_name: filebeat
    volumes:
      - ./filebeat/filebeat.yml:/usr/share/filebeat/filebeat.yml:ro
      - /var/lib/docker/containers:/var/lib/docker/containers:ro
      - /var/run/docker.sock:/var/run/docker.sock #needed for autodiscover


我以前的手动执行filebeat.yml文件不起作用,因此我尝试了许多示例,但没有任何效果。这是一个我认为应该起作用的示例,但事实并非如此。 Docker容器启动没有问题,但是无法以某种方式从日志文件读取。
filebeat.autodiscover:
  providers:
    - type: docker

filebeat.inputs:
- type: log
  enabled: true
  paths:
    - /var/lib/docker/containers/*/*.log
  json.keys_under_root: true
  json.add_error_key: true
  fields_under_root: true
  fields:
    application: "myapp"

cloud.id: "iamnotshowingyoumycloudidthisisjustfake"
cloud.auth: "elastic:mypassword"


我也尝试过这样的事情
filebeat.autodiscover:
  providers:
    - type: docker
      templates:
        config:
          - type: docker
            containers.ids:
              - "*"

filebeat.inputs:
  - type: docker
    containers.ids:
      - "*"
    processors:
      - add_docker_metadata:
    fields:
      application: "myapp"
    fields_under_root: true

cloud.id: "iamnotshowingyoumycloudidthisisjustfake"
cloud.auth: "elastic:mypassword"

我不知道还有什么尝试,filebeat日志仍然显示
 "harvester":{"open_files":0,"running":0}}

我100%确定来自容器的日志位于/var/lib/docker/containers/*/*.log ...下,正如我所说的,当手动安装Filebeat时,它工作正常,而不是docker image。

有什么建议吗?

最佳答案

嗯,我在Filebeat配置中看不到任何明显的原因,为什么它不起作用,我有一个非常相似的配置正在运行6.x Filebeat。

我建议在容器上执行docker inspect并确认安装在那里,也许检查权限,但是错误可能会在日志中显示。

您还可以尝试使用container input吗?我相信这是7.2+中推荐的容器日志方法:https://www.elastic.co/guide/en/beats/filebeat/7.2/filebeat-input-container.html
