2. DB(Mysql) + Kafka + Zookeeper 띄우기

2.1. docker_compose.yml 작성

version: '3.8'

services:
  # 🐘 Zookeeper
  zookeeper:
    image: bitnami/zookeeper:latest
    container_name: zookeeper
    ports:
      - "2181:2181"
    environment:
      - ALLOW_ANONYMOUS_LOGIN=yes

  # 🦁 Kafka
  kafka:
    image: confluentinc/cp-kafka:7.5.1
    container_name: kafka
    ports:
      - "9092:9092"
    environment:
      KAFKA_BROKER_ID: 1
      KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181
      KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://localhost:9092
      KAFKA_LISTENER_SECURITY_PROTOCOL_MAP: PLAINTEXT:PLAINTEXT
      KAFKA_OFFSETS_TOPIC_REPLICATION_FACTOR: 1
    depends_on:
      - zookeeper

  # 🐬 MySQL
  mysql:
    image: mysql:8
    container_name: mysql-container
    ports:
      - "3306:3306"
    environment:
      MYSQL_ROOT_PASSWORD: 루트계정 비밀번호 입력
      MYSQL_DATABASE: testdb
    restart: always

• image : 이미지 + 버전
• container_name : 컨테이너 이름 지정
• ports : 로컬 포트와 컨테이너 포트 연결
• environment : 설정
