Simple Docker Filebeat Elasticsearch Composition does not Log out Docker Logs

Question

I created a docker compose for educational purposes to explore the Filebeat Logging capabilities, but I do not get Filebeat to log the logs a specific container.

I create an elastic process with certificate security, then a Kibana container on top of that. I configure the Kibana/Elastic Setup with a Filebeat container and then I would have expected the Logs in the "Discover" Tab in Kibana, but nothing is visible, no logs.

Here is my docker-compose:

services:
  elastic-setup:
    image: docker.elastic.co/elasticsearch/elasticsearch:8.12.1
    user: "0"
    volumes:
      - ./elasticsearch/certs:/usr/share/elasticsearch/config/certs
    command: >
      bash -c '
        if [ ! -f config/certs/ca.zip ]; then
          echo "Creating CA";
          bin/elasticsearch-certutil ca --silent --pem -out config/certs/ca.zip;
          unzip config/certs/ca.zip -d config/certs;
        fi;
        if [ ! -f config/certs/certs.zip ]; then
          echo "Creating certs";
          echo -ne \
          "instances:\n"\
          "  - name: search\n"\
          "    dns:\n"\
          "      - search\n"\
          "      - localhost\n"\
          "    ip:\n"\
          "      - 127.0.0.1\n"\
          > config/certs/instances.yml;
          bin/elasticsearch-certutil cert --silent --pem -out config/certs/certs.zip --in config/certs/instances.yml --ca-cert config/certs/ca/ca.crt --ca-key config/certs/ca/ca.key;
          unzip config/certs/certs.zip -d config/certs;
        fi;
        echo "Setting file permissions"
        chown -R root:root config/certs;
        find . -type d -exec chmod 750 \{\} \;;
        find . -type f -exec chmod 640 \{\} \;;
        echo "Waiting for Elasticsearch availability";
        until curl -s --cacert config/certs/ca/ca.crt https://search:9200 | grep -q "missing authentication credentials"; do sleep 30; done;
        echo "Setting kibana_system password";
        until curl -s -X POST --cacert config/certs/ca/ca.crt -u "elastic:elastic" -H "Content-Type: application/json" https://search:9200/_security/user/kibana_system/_password -d "{\"password\":\"kibana\"}" | grep -q "^{}"; do sleep 10; done;
        echo "All done!";

The Filebeat Setup (I save in a filebeat subfolder, see volumes) is pretty simple:

filebeat.inputs:
  - type: filestream
    id: my-filestream-id
    enabled: false
# ============================== Filebeat modules ==============================

filebeat.config.modules:
  path: ${path.config}/modules.d/*.yml
  reload.enabled: false
  #reload.period: 10s

filebeat.autodiscover:
  providers:
    - type: docker
      hints.enabled: true
      hints.default_config.enabled: false

# ======================= Elasticsearch template setting =======================

setup.template.settings:
  index.number_of_shards: 1
setup.kibana:
  host: "kibana:5601"
  username: elastic
  password: elastic
output.elasticsearch:
  # Array of hosts to connect to.
  hosts: ["search:9200"]

  # Performance preset - one of "balanced", "throughput", "scale",
  # "latency", or "custom".
  preset: balanced

  # Protocol - either `http` (default) or `https`.
  protocol: "https"

  # Authentication credentials - either API key or username/password.
  #api_key: "id:api_key"
  username: "elastic"
  password: "elastic"

  ssl.certificate_authorities: ["/usr/share/filebeat/config/certs/ca/ca.crt"]
  ssl.certificate: "/usr/share/filebeat/config/certs/search/search.crt"
  ssl.key: "/usr/share/filebeat/config/certs/search/search.key"

Everything is more or less copied from the Elastic Documentation but:

1. Although I get some installed Dashboards in Kibana, during Filebeat initialiazation I get a lot of "kibana-1 | [2024-02-19T01:10:10.966+00:00][ERROR][http] 400 Bad Request" Logs and
2. As mentioned, no Logs from my Test "Logger" Container visible in the Kibana Discover Tab

Answer 1

I think you should use "container" filebeat input type instead of filestream.
