docker-compose start 无法从数据库获取连接

问题描述 投票：0回答：1

当我这样做时

docker-compose up
，一切正常，没有任何问题，后端成功连接到数据库，
但是当我执行 
docker-compose stop
以及 
docker-compose start
之后，即使数据库正在工作，后端也无法再次连接到数据库。

之后我用查询测试了数据库，一切都很好
这并不是因为数据库尚未准备好连接，因为商店容器依赖于 

postgresdb
容器，并且我尝试在测试带有查询的 
postgresdb
容器后运行商店容器

docker-compose.yml:

version: "3.8"
services:
  postgres:
    image: postgres:16.2
    container_name: postgresdb
    networks:
      - compose-shop
    ports:
      - "5432:5432"
    environment:
      POSTGRES_PASSWORD: postgres
    volumes:
      - ./init-db.sql:/docker-entrypoint-initdb.d/init-db.sql

  shop:
    image: danielschiavo/shop:1.0.0
    container_name: shop
    networks:
      - compose-shop
    ports:
      - "8080:8080"
    volumes:
      - filestorage:/home/shop/imagens
    depends_on:
      - postgres

networks:
  compose-shop:
    driver: bridge
    
volumes:
  filestorage:


application-prod.properties:

spring.datasource.url=jdbc:postgresql://postgresdb:5432/shop
spring.datasource.username=postgres
spring.datasource.password=postgres

这看起来您的容器之间存在竞争条件。

我建议您的客户端服务建立对数据库服务运行状况的依赖。

在下面的

docker-compose.yml
中有

    数据库服务上的
  • a 
    healthcheck
    ，以便只有在准备好接受连接时才会将其标记为“健康”并且
  • a 
    depends_on
    在客户端服务中，以便仅当数据库准备好接受连接时才会继续。

client
服务只是一个占位符，应适应您的 
shop
服务。它连接到数据库并执行简单的查询。上下几次这个堆栈，让自己确信服务之间的通信是稳健的。

version: "3.8"
services:
  postgres:
    image: postgres:16.2
    container_name: postgresdb
    networks:
      - compose-shop
    ports:
      - "5432:5432"
    environment:
      - POSTGRES_USER=postgres
      - POSTGRES_PASSWORD=postgres
    healthcheck:
      test: ["CMD-SHELL", "pg_isready -U postgres"]
      interval: 5s
      timeout: 5s
      retries: 5

  client:
    image: postgres:16.2
    container_name: client
    networks:
      - compose-shop
    environment:
      - PGPASSWORD=postgres
    depends_on:
      postgres:
        condition: service_healthy
    command: sh -c "psql -h postgres -U postgres -c 'SELECT * from pg_user;'"

networks:
  compose-shop:
