Docker - Angular 应用映像不工作（“/etc/nginx/html/index.html”未找到）

Question

所以我有一个角度应用程序，我已经为它创建了一个 Dockerfile 。试图从中创建构建，并在解决一些构建问题后成功。容器正在运行，但应用程序没有运行，这是我在 NgInx 日志中看到的

2021/11/26 13:13:03 [error] 8#8: *1 "/etc/nginx/html/index.html" is not found (2: No such file or directory), client: 172.17.0.1, server: localhost, request: "GET / HTTP/1.1", host: "localhost:82"
172.17.0.1 - - [26/Nov/2021:13:13:03 +0000] "GET / HTTP/1.1" 404 555 "-" "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/94.0.4606.81 Safari/537.36 Edg/94.0.992.50"

这是我的 docker 文件

FROM node:12 as build-stage
RUN mkdir -p /app
WORKDIR /app
COPY package.json ./
RUN npm install
COPY . /app
RUN npm run build

FROM nginx:1.17.1-alpine as production-stage
COPY nginx.conf /etc/nginx/nginx.conf
COPY --from=build-stage /app/dist/java-poc /usr/share/nginx/html

这是我在 package.json 文件中的构建脚本

"scripts": {  
    "build": "node --max_old_space_size=4096 node_modules/@angular/cli/bin/ng build --prod",
 },

这是我试图在 NGINX 映像中覆盖的 NgInx 配置文件。

有人能在某个方向指出我这里出了什么问题吗？

编辑：刚刚检查 index.html 是否存在。这也检查了

我的 conf 文件也被复制到那里，我也匹配了内容

Answer 1

似乎我将构建文件复制到错误的目录中。现在解决了。只需要更改dockerfile这一行

COPY --from=build-stage /app/dist/java-poc /etc/nginx/html
