nginx 背后的 Angular 5 dockerized 应用程序

Question

我在尝试部署我的 Angular 5.1.2 应用程序时遇到问题，基本上它在本地运行良好，但它在我的服务器上显示一个空白页面，出现 404 错误，例如

加载脚本元素失败，源是...

对于像 inline.js、polyfills.js、scripts.js、main.js ...

我认为我在路径上做错了什么，知道如何解决这个问题吗？

Dockerfile

FROM node:boron

# Create app directory
WORKDIR /usr/app

# Install app dependencies
COPY package.json .
RUN npm install --quiet

# Bundle app source
COPY . .

EXPOSE 4200

我的 nginx 配置的一部分

server {
    listen 443 ssl http2;
    listen [::]:443 ssl http2;

    server_name url www.url;

    location / {
        proxy_pass         http://localhost:4200/;
        proxy_set_header X-Forwarded-Host $host;
        proxy_set_header X-Forwarded-Server $host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        try_files $uri $uri/ /index.html =404;
    }

    root /var/www/iothings-app;
 }

我运行：

docker build -t things-app .
docker run --name iothings-app -p 0.0.0.0:4200:4200 -d things-app

首先应该使用docker ps | grep 'things-app' 检查您的容器ID。获得 ID 后，您可以使用 docker logs ID 并检查问题所在。其次，您没有安装 Angular CLI，但您尝试构建。我不认为它会起作用。 Bellow 是我经常用来部署我的 Angular 应用程序的一个示例。但我使用http-server。我认为哪一个足以部署您的应用程序。还有一件事，如果您没有包含任何节点服务器代码（MEAN 堆栈），那么您根本不需要运行 npm start。有时我使用 expressJs 部署 MEAN 堆栈，以便我使用 npm start 来启动我的服务器。这是我的工作示例：

FROM node:alpine
# Create app directory
RUN mkdir -p /usr/src/app
WORKDIR /usr/src/app

# Install http-server
RUN npm install -g http-server

# Bundle app source
COPY . /usr/src/app

# Install AngularCLI
npm install -g @angular/cli

# Install app dependencies
COPY package.json /usr/src/app/
COPY .angular-cli.json /usr/src/app/
RUN npm install

CMD [ "ng", "build" ]

EXPOSE 3000

CMD ["cd", "/usr/src/app/dist", "http-server" ,"-p", "3000"]

最后，您可以使用

构建和运行您的容器

docker build -t things-app .
docker run --name iothings-app -p 4200:3000 -d things-app

您的应用将成为http://SERVER_IP_ADRESS:3000 上的服务器

您不再需要在此处配置 nGinx，因为您只是通过 IP 和端口为 App 提供服务
