在 Docker Compose 中运行 Sequelize Migration

如何解决在 Docker Compose 中运行 Sequelize Migration

我正在尝试弄清楚如何使用我的 docker compose 设置运行 Sequelize 数据库迁移，但到目前为止，两种不同的方法都失败了。安装 cli 后，我第一次尝试在 Dockerfile 中运行 npx sequelize db:migrate，但我认为失败了，因为数据库容器尚未运行，然后在第二次尝试创建一个容器依赖于数据库容器并使用 wait-for-it.sh 运行命令，但这导致我的 app 容器引用失败。两次尝试都失败了，但我想我理解需要发生的逻辑。

• 使用 Docker 文件内容构建容器
• 启动数据库容器以运行数据库
• 运行 sequelize 迁移
• 启动应用服务器

这听起来正确吗？有人知道好的方法吗？

Dockerfile：

FROM node:alpine
# Setting working directory. All the paths will be relative to workdir
workdir /usr/src/app
# Add bash to docker
RUN apk update && apk add bash
# Install dependencies
copY package*.json ./
RUN npm install
# Install sequelize-cli for migrations
RUN npm install sequelize-cli --save
# copying source files
copY . .
# copying shell script to ensure DB starts prior to server
copY wait-for-it.sh .

# Run sequelize database migrations
# RUN npx sequelize db:migrate # Failed ATTEMPT == ERROR: connect ECONNREFUSED 127.0.0.1:5432

# Build app
RUN npm run build
# Port
EXPOSE 3000
# Run the app
CMD [ "npm","start" ]

docker-compose.yml：

version: "3.9"
services:
    redis:
        image: redis:alpine
    database:
        image: postgres
        ports:
            - "5432:5432"
        environment: 
            POSTGRES_USER: ${DB_USERNAME}
            POSTGRES_PASSWORD: ${DB_PASSWORD}
            POSTGRES_DB: ${DB_DATABASE}
        volumes:
            - nextjs_auth_template:/var/lib/postgresql/data/ # persist data even if container shuts down
    app:
        image: nextjs-auth-boilerplate
        build: .
        depends_on:
            - redis
            - database
        # command: ["./wait-for-it.sh","database:5432","--","node","server.js"]
        ports:
            - "3000:3000"
        environment: 
            - REdis_HOST=redis
            - DB_HOSTNAME=database
    # migration:
    #     image: app:latest # Failed ATTEMPT == pull access denied for app
    #     command: ["./wait-for-it.sh","npm","run","db:migrate"]
    #     depends_on:
    #         - database
volumes:
    nextjs_auth_template:

.env:

DB_USERNAME=postgres
DB_PASSWORD=''
DB_DATABASE=nextjs_auth_template
DB_HOSTNAME=127.0.0.1
DB_URL=postgresql://postgres@127.0.0.1/nextjs_auth_template

package.json (npm run db:migrate)：

"db:migrate": "node_modules/.bin/sequelize db:migrate",
