如何在生产中运行 docker-compose

Question

我已经用 nginx 前端构建了一个 MEAN 堆栈应用程序。

我有 2 个 docker 文件 - 一个用于前端，一个用于后端 我有一个 docker-compose 文件，可以将它们与数据库一起拉到一起

这在我的开发机器上效果很好

然后我将图像推送到我的 dockerhub 站点

在我的生产 ubuntu 机器上，我从我的 dockerhub 存储库中提取我想要的图像

但是我应该如何运行它们呢？

我将我的 docker-compose 文件传输到服务器并尝试运行它：

docker-compose -f docker-compose.prod.yml up

但它抱怨文件夹结构不是我的开发机器上的：

ERROR: build path /home/demo/api either does not exist, is not accessible, or is not a valid URL.

我不想将所有代码都放在服务器上并重新构建它。这肯定违背了使用 dockerhub 映像的目的吗？

我还需要 docker compose 文件来拉入 .prod.env 文件以获取数据库凭据等。

我知道我在这里遗漏了一些东西。 如何运行我的图像而不从头开始重建它们？

为此我需要其他服务吗？

使用包含 dockerhub 路径的完整图像名称为我解决了这个问题。

如下图所示的工作解决方案：

Dockerfile-PROD-UI

#GET ANGULAR ========================================
FROM node:10-alpine as base
WORKDIR /usr/src/app
COPY ui/package*.json ./
RUN npm install @angular/cli && npm install
COPY ui/. .

#BUILD ANGULAR ========================================
FROM base as build 
RUN npm run build
#RUN ls -lha

#NGINX ========================================
FROM nginx:1.18.0-alpine
COPY --from=build /usr/src/app/dist /usr/share/nginx/html
COPY ./nginx.conf /etc/nginx/conf.d/default.conf

Dockerfile-PROD-API

#SERVER ========================================
FROM node:10-alpine as server

WORKDIR /app

# Install dependencies
COPY package*.json ./
RUN npm install

# Bundle app source
COPY . .

#RUN ls -lha

EXPOSE 3000

CMD ["npm", "run", "start"]
