Filebeat: read file inside container

[pranay_sankpal]

Hi,

We are setting up logging for services running on kubernetes. These services generates logs file in the APP_DIR inside a container. How can I ship these logs to ES?

I've refered :
https://www.elastic.co/guide/en/beats/filebeat/current/configuration-autodiscover.html

Deployed filebeat as :

elastic/beats/blob/master/deploy/kubernetes/filebeat-kubernetes.yaml

my filebeat configmap :

kind: ConfigMap
metadata:
  name: filebeat-config
  namespace: kube-system
  labels:
    k8s-app: filebeat
data:
  filebeat.yml: |-
    setup.dashboards.enabled: true
    setup.template.enabled: true

    setup.template.settings:
      index.number_of_shards: 1

    filebeat.autodiscover:
      providers:
        - type: kubernetes
          templates:
            - condition.contains:
                kubernetes.container.image: my_app
              config:
                - type: my_app-logs
                  paths:
                    - "/var/www/my_app/app.log"
    processors:
      - add_cloud_metadata:
    cloud.id: ${ELASTIC_CLOUD_ID}
    cloud.auth: ${ELASTIC_CLOUD_AUTH}
    output.elasticsearch:
      hosts: ['${ELASTICSEARCH_HOST:elasticsearch}:${ELASTICSEARCH_PORT:9200}']
      username: ${ELASTICSEARCH_USERNAME}
      password: ${ELASTICSEARCH_PASSWORD}

Is it possible to read files inside container using filebeat-daemonset deployment?

Is above approach correct?

Some direction would be helpful.

I never used kubernetes that much, but it's like Docker, right. So maybe something like this:
https://kubernetes.io/docs/tasks/access-application-cluster/communicate-containers-same-pod-shared-volume/

A shared volume would be my best bet.
