Fluentd: Docker Compose ​

Following the official documentation, I found that the solution described here is already very outdated. Doesn't work. So I searched and found the solution here: [Issue #391] Docker compose example from official docs broken?

Prepare Docker ​

docker-compose.yml ​

yaml
version: "3"

services:
  web:
    image: httpd
    ports:
      - "80:80"
    links:
      - fluentd
    logging:
      driver: "fluentd"
      options:
        fluentd-address: localhost:24224
        tag: httpd.access

  fluentd:
    build: ./fluentd
    volumes:
      - ./fluentd/conf:/fluentd/etc
    links:
      - "elasticsearch"
    ports:
      - "24224:24224"
      - "24224:24224/udp"

  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch:8.1.2
    container_name: elasticsearch
    environment:
      - "discovery.type=single-node"
      - xpack.security.enabled=false
    expose:
      - "9200"
    ports:
      - "9200:9200"

  kibana:
    image: docker.elastic.co/kibana/kibana:8.1.2
    links:
      - "elasticsearch"
    ports:
      - "5601:5601"
