Azure Linux Web 服务器没有响应我的 Docker 容器

我正在尝试通过 Azure 容器注册表将我的小型节点 js 应用程序部署到 azure web 服务。

这是我的 server.js

const express = require('express');
const path = require('path');

const app = express();

// Serve the static files from the build directory
app.use(express.static(path.join(__dirname, 'build')));

// Serve the React app on all other routes
app.get('*', (req, res) => {
    res.sendFile(path.join(__dirname, 'build', 'index.html'));
});

// Start the server
const port = 3000;
app.listen(port, () => {
    console.log('BEGIN');
    console.log(`Server started on port ${port}`);
});

这是我的 Dockerfile

# Use the official Node.js 16.x image as the base image
FROM node:16-alpine

WORKDIR /app

RUN npm install express

COPY "./server.js" .
COPY "./packages/claim-management/build" "./build"

EXPOSE 3000
CMD ["node", "server.js"]

我在端口暴露的配置中添加了两个变量。

  WEBSITES_CONTAINER_START_TIME_LIMIT   = 400
  WEBSITES_PORT                         = 3000

这是我来自 Azure 的日志：

容器在本地工作，我可以通过命令

docker run -p 3000:3000

运行它，但我可以看到 Azure 试图通过 `docker run -d --expose=3000 启动容器。我不知道我做错了什么。

回答如下：

我修好了： 只要确保（如果您是 mac m1 用户或任何其他与 Azure Web 服务不兼容的处理器）您将平台添加到您的 Dockerfile：

# Need platform to much with your current extension
FROM --platform=linux/amd64 node:16-alpine

WORKDIR /app

COPY "./server.js" .

EXPOSE 3000

CMD ["node", "server.js"]

确保在应用服务的配置部分使用 WEBSITES_PORT 变量，并且它与 Dockerfile 中的 EXPOSE 端口相匹配！
