如何解决Docker构建Angular 15项目时卡在RUN npm run build步骤的问题

我通过ng new ng-sandbox-15创建了全新的Angular 15项目，复用了之前可正常运行的Angular 14项目的Dockerfile、.dockerignore和nginx.conf文件，但构建时始终卡在RUN npm run build步骤。从日志来看，Angular的构建任务已经在26.5秒内完成，但该Docker步骤却一直卡住超过20分钟。

Dockerfile #

FROM node:16-alpine as builder

# Copy dependency definitions
COPY package.json package-lock.json ./

# disabling ssl for npm for Dev or if you are behind proxy
RUN npm set strict-ssl false

## installing and Storing node modules on a separate layer will prevent unnecessary npm installs at each build
RUN npm ci && mkdir /app && mv ./node_modules ./app

# Change directory so that our commands run inside this new directory
WORKDIR /app

# Get all the code needed to run the app
COPY . /app/

# Build the application
RUN npm run build


FROM nginx:1.17-alpine
## From 'builder' copy published folder
COPY --from=builder /app/dist /usr/share/nginx/html

COPY nginx/nginx.conf /etc/nginx/nginx.conf

# Expose the port the app runs in
EXPOSE 4000

CMD ["nginx", "-g", "daemon off;"]

问题细节 #

从截图可见，Angular构建任务已显示在26.5秒完成，但Docker的RUN npm run build步骤却持续卡住超过20分钟。之前见过类似问题，但不认同将构建命令放到CMD中的方案——这会导致容器启动时才执行构建，而镜像构建阶段就尝试复制未生成的dist目录到nginx，逻辑完全错误。
