Docker Compose 部署 Postgres18

postgers18 及以后映射路径为 /var/lib/postgresql, 与 17 的 /var/lib/postgresql/data 不同

使用绑定目录挂载

services:
  postgres:
    image: postgres:18-alpine
    container_name: postgres18-bind-mount
    environment:
      TZ: Asia/Shanghai
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: postgres
      POSTGRES_DB: postgres
      POSTGRES_INITDB_ARGS: "--encoding=UTF8 --locale=C.UTF-8"
    volumes:
      - ./postgresql:/var/lib/postgresql
    ports:
      - "5432:5432"
    healthcheck:
      test: ["CMD-SHELL", "pg_isready -U postgres"]
      interval: 10s
      timeout: 5s
      retries: 5
    logging:
      options:
        max-size: "10m"
        max-file: "3"

使用命名卷方式挂载

services:
  postgres:
    image: postgres:18-alpine
    container_name: postgres18-volume
    environment:
      TZ: Asia/Shanghai
      POSTGRES_USER: postgres
      POSTGRES_PASSWORD: postgres
      POSTGRES_DB: postgres
      POSTGRES_INITDB_ARGS: "--encoding=UTF8 --locale=C.UTF-8"
    volumes:
      - postgres_data:/var/lib/postgresql
    ports:
      - "5432:5432"
    healthcheck:
      test: ["CMD-SHELL", "pg_isready -U postgres"]
      interval: 10s
      timeout: 5s
      retries: 5
    logging:
      options:
        max-size: "16m"
        max-file: "4"
 
volumes:
  postgres_data:
