Docker容器运行后立即退出

Question

我有一个 Angular 17 项目，我想对其进行 dockerize。我已经构建了我的图像，当我尝试使用

docker run -dit --name <container name> <imagename>

运行容器时，但容器随后立即退出。当我运行

docker ps

时，我的容器没有出现。

Dockerfile：

# Use node image as builder
FROM node:18.14 AS builder

# Set working directory in the container
WORKDIR /app

# Copy package.json and package-lock.json to the container
COPY package.json package-lock.json ./

# Install dependencies
RUN npm install

# Copy the rest of the application code
COPY . .

# Build the application
RUN npm run build --prod

# Use nginx image for serving the application
FROM nginx:latest

# Copy built application files from builder stage to nginx directory
COPY --from=builder /app/dist/project /usr/share/nginx/html

# Expose port 80 for nginx
EXPOSE 80

# Start nginx in foreground
CMD ["nginx", "-g", "daemon off;"]

我注意到我的图像无法在 docker 桌面中进行分析，如以下屏幕截图所示：

正如您在评论中提到的

exec /docker-entrypoint.sh: exec format error

是真正需要解决的问题。 你能想出一个最小的、可重现的例子吗？举个例子，这对我来说在本地工作

# Use node image as builder
FROM node:18.14 AS builder

# Set working directory in the container
WORKDIR /app

# (pretend to) Build the application
RUN echo "Hello world" > out.txt

# Use nginx image for serving the application
FROM nginx:latest

# Copy built application files from builder stage to nginx directory
COPY --from=builder /app/ /usr/share/nginx/html

这可能与处理器架构差异有关，请参阅在 M1 Mac 上构建时 Docker 失败（exec /usr/local/bin/docker-entrypoint.sh：exec 格式错误） 和 https://docs.docker.com/构建/指南/多平台/

如果您在本地构建图像并在其他地方运行它，这很可能是解决方案 - https://stackoverflow.com/a/69636473/131391

如果您在本地构建和运行，那么我首先确保您可以在编写 Dockerfile 之前简单地运行提到的基础映像。例如

docker run nginx:latest
